Constipation affects different persons differently; some persons with very obstinate constipation feel no inconvenience even though the bowls do not move more than once or twice a week, while others are worried and upset if the regular daily movement does not take place. The general health may not be affected for some time, and apart from a bad taste in the mouth and furred tongue there may be no other inconvenience, but if continued for long it are a feeling of distension of the stomach after food, belching, yawning, foul breath, apathy for any kind of physical or mental work, irritability, sleeplessness, a state of anxiety and unnecessary worries.
Muddiness of the skin, acne, pimples and boils may also be present. But all these symptoms are not present in all cases. In asthmatic subjects it often brings on an attack which is relieved by a purgative. The constant presence of hard lumps of facial matter in the intestine causes irritation, as a result of which a small quantity of thick mucus and a little facial matter are frequently, evacuated which simulates dysentery. Piles, fissure, ulceration or chronic inflammation of the colon or rectum may result from it.
The first step in the treatment of constipation is to remove the cause and adopt a diet containing a sufficient quantity of solid residue to simulate the intestinal muscle. For this purpose the diet should contain a liberal quantity of whole wheat bread, bran cooked in different ways, oatmeal, unpolished cereals, green vegetables, fresh fruit and nuts.We have reviewed a lot of guide for you and have found to be the best. The quantity of meat, poultry, fish, eggs, and other concentrated foods, should be limited. Fresh vegetables contain, in addition to indigestible residue, vitamins, iron, calcium, phosphorus and other minerals necessary for the maintenance of health.
Canned vegetables and fruit are not so wholesome as most of these elements deteriorate in the process of canning. Of the fruits papaya, guava, figs, and mangoes have a laxative action. The food should be eaten slowly and well masticated, the mouth and teeth kept clean and water or other liquid taken in sufficient quantity, especially after sweating and in hot weather.
Are you looking for natural lower back pain relief? Do you live in Fort Collins, Colorado and wish that you could get out and do all the things this beautiful city has to offer? As you know, living in Fort Collins gives one access to a multitude of outdoor activities that can be done year round, and for those who love to stay active, there really is no better place to be. But if you’re stuck at home with a bum back, it can be hard to really get out there and do all those fun things in the Colorado sun. Even daily tasks can be daunting when dealing with lower back pain.
Thankfully Fort Collins also has a wonderful holistic community that can help you get back on your feet quickly, without the use of drugs or invasive procedures. Here are some holistic techniques to try that will get you back in the saddle again…or the snowshoes…or the skis…or the snowboard, or….well, you get the idea!
Massage
Massage is probably the best known modality for releasing tension within the body, and is an excellent way to relieve back pain. There are different styles of massage ranging from relaxation to therapeutic. The severity of your back pain will more than likely determine the style you choose. Relaxation massage is wonderful for increasing blood flow, lessening pain and tension and can possibly increase the range of motion in your back. Sports massage, neuromuscular rehabilitation techniques and other therapeutic styles focus more on increasing range motion, re-organizing muscle fibers to an appropriate resting length, and correcting established muscular patterns so they are more healthy and functional. Either way, massage is great way to relieve back pain.
Acupuncture
Acupuncture has been around for thousands of years. By focusing on the channels of energy that run through the body, also known as meridians, an Acupuncturist can recognize any blocks that are causing pain and dysfunction in the body. An Acupuncturist stimulates our meridians by placing thin needles accurately and gently underneath the skin along the lines of the energy channel. This stimulation helps to remove the blocks that are preventing our life-force from flowing freely. The result is a body that is pain-free, balanced, and healthy.
Yoga
Also an ancient practice of health and wellness, yoga has been embraced by our culture enthusiastically, and its popularity continues to grow. Yoga is a wonderful exercise to help alleviate lower back pain. Its gentle, slow and methodical stretches, coupled with deep breathing can have a profound effect on the body and mind. Yoga looks to establish in its practitioners core strength, flexibility, quiet mindfulness, and overall health.
Network Chiropractic Care
While still considered a form of chiropractic care, Network Chiropractic techniques are completely different than traditional methods. In a session, the Chiropractor focuses on releasing distortions within the spinal cord by gently applying pressure to the connection points of where the spinal cord and vertebrae touch. Rather than focusing on adjusting the vertebrae themselves, as in traditional chiropractic, Network Chiropractic focuses on specific contact points, called spinal gateways, which alters the state or tone of the spinal cord, allowing the vertebrae to self correct and the neurology to release tension held in the system. Not only will Network Chiropractic alleviate lower back pain, it supports the body in staying balanced and healthy, eliminating future occurrences.
Of all the holistic options available in Fort Collins that can be used as natural lower back , I would have to say that Network Chiropractic Care is the best. Not only are you alleviating the dysfunction of lower back pain, you are also given the tools to continue living pain free, as well as having a fully functional and balanced body from the inside out. For the best Network Chiropractic care for lower back pain in Fort Collins, Colorado visit or call 970-224-5006 to schedule your complimentary 20 minute consultation today!
In 1990 one of us published with his colleagues a paper suggesting that a specific genetic anomaly was linked to alcoholism (Blum et al. 1990). Unfortunately it was often erroneously reported that they had found the “alcoholism gene,” implying that there is a one-to-one relation between a gene and a specific behavior. Such misinterpretations are common-readers may recall accounts of an “obesity gene,” or a “personality gene.” Needless to say, there is no such thing as a specific gene for alcoholism, obesity or a particular type of personality. However, it would be naive to assert the opposite, that these aspects of human behavior are not associated with any particular genes. Rather the issue at hand is to understand how certain genes and behavioral traits are connected.
In the past five years we have pursued the association between certain genes and various behavioral disorders. In molecular genetics, an association refers to a statistically significant incidence of a genetic variant (an allele) among genetically unrelated individuals with a particular disease or condition, compared to a control population. In the course of our work we discovered that the genetic anomaly previously found to be associated with alcoholism is also found with increased frequency among people with other addictive, compulsive or impulsive disorders. The list is long and remarkable-it comprises alcoholism, substance abuse, smoking, compulsive overeating and obesity, attention-deficit disorder, Tourette’s syndrome and pathological gambling.
We believe that these disorders are linked by a common biological substrate, a “hard-wired” system in the brain (consisting of cells and signaling molecules) that provides pleasure in the process of rewarding certain behavior. Consider how people respond positively to safety, warmth and a full stomach. If these needs are threatened or are not being met, we experience discomfort and anxiety. An inborn chemical imbalance that alters the intercellular signaling in the brain’s reward process could supplant an individual’s feeling of well being with anxiety, anger or a craving for a substance that can alleviate the negative emotions. This chemical imbalance manifests itself as one or more behavioral disorders for which one of us (Blum) has coined the term “reward deficiency syndrome.”
This syndrome involves a form of sensory deprivation of the brain’s pleasure mechanisms. It can be manifested in relatively mild or severe forms that follow as a consequence of an individual’s biochemical inability to derive reward from ordinary, everyday activities. We believe that we have discovered at least one genetic aberration that leads to an alteration in the reward pathways of the brain. It is a variant form of the gene for the dopamine D2 receptor, called the A1 allele. This is the same genetic variant that we previously found to be associated with alcoholism. In this review we shall look at evidence suggesting that the A1 allele is also associated with a spectrum of impulsive, compulsive and addictive behaviors. The concept of a reward deficiency syndrome unites these disorders and may explain how simple genetic anomalies give rise to complex aberrant behavior.
The pleasure and reward system in the brain was discovered by accident in 1954. The American psychologist James Olds was studying the rat brain’s alerting process, when he mistakenly placed the electrodes in a part of the limbic system, a group of structures deep within the brain that are generally believed to play a role in emotions. When the brain was wired so that the animal could stimulate this area by pressing a lever, Olds found that the rats would press the lever almost nonstop, as many as 5,000 times an hour. The animals would stimulate themselves to the exclusion of everything else except sleep. They would even endure tremendous pain and hardship for an opportunity to press the lever. Olds had clearly found an area in the limbic system that provided a powerful reward for these animals.
Research on human subjects revealed that the electrical stimulation of some areas of the brain (the medial hypothalamus) produced a feeling of quasi-orgasmic sexual arousal (Olds and Olds 1969). If certain other areas of the brain were stimulated, an individual experienced a type of light-headedness that banished negative thoughts. These discoveries demonstrated that pleasure is a distinct neurological function that is linked to a complex reward and reinforcement system (Hall, Bloom and Olds 1977).
During the past several decades research on the biological basis of chemical dependency has been able to establish some of the brain regions and neurotransmitters involved in reward. In particular it appears that the dependence on alcohol, opiates and cocaine relies on a common set of biochemical mechanisms (Cloninger 1983, Blum et al. 1989). A neuronal circuit deep in the brain involving the limbic system and two regions called the nucleus accumbens and the globus pallidus appears to be critical in the expression of reward for people taking these drugs (Wise and Bozarth 1984). Although each substance of abuse appears to act on different parts of this circuit, the end result is the same: Dopamine is released in the nucleus accumbens and the hippocampus (Koob and Bloom 1988). Dopamine appears to be the primary neurotransmitter of reward at these reinforcement sites.
Although the system of neurotransmitters involved in the biology of reward is complex, at least three other neurotransmitters are known to be involved at several sites in the brain: serotonin in the hypothalamus, the enkephalins (opioid peptides) in the ventral tegmental area and the nucleus accumbens, and the inhibitory neurotransmitter GABA in the ventral tegmental area and the nucleus accumbens (Stein and Belluzi 1986, Blum 1989). Interestingly, the glucose receptor is an important link between the serotonergic system and the opioid peptides in the hypothalamus. An alternative reward pathway involves the release of norepinephrine in the hippocampus from neuronal fibers that originate in the locus coeruleus.
In a normal person, these neurotransmitters work together in a cascade of excitation or inhibition-between complex stimuli and complex responses-leading to a feeling of well being, the ultimate reward (Cloninger 1983, Stein and Belluzi 1986, Blum and Koslowski 1990). In the cascade theory of reward, a disruption of these intercellular interactions results in anxiety, anger and other “bad feelings” or in a craving for a substance that alleviates these negative emotions. Alcohol, for example, is known to activate the norepinephrine system in the limbic circuitry through an intercellular cascade that includes serotonin, opioid peptides and dopamine. Alcohol may also act directly through the production of neuroamines that interact with opioid receptors or with dopaminergic systems (Alvaksinen et al. 1984; Blum and Kozlowski 1990). In the cascade theory of reward, genetic anomalies, prolonged stress or long-term abuse of alcohol can lead to a self-sustaining pattern of abnormal cravings in both animals and human beings.
Support for the cascade theory can be derived from a series of experiments on strains of rats that prefer alcohol to water. Compared to normal rats, the alcohol-preferring rats have fewer serotonin neurons in the hypothalamus, higher levels of enkephalin in the hypothalamus (because less is released), more GABA neurons in the nucleus accumbens (which inhibit the release of dopamine), a reduced supply of dopamine in the nucleus accumbens and a lower density of dopamine D2 receptors in certain areas of the limbic system (Russell, Lanin and Taljaard 1988; McBride et al. 1990; Zhou et al. 1990; McBride et al. 1993).
These studies suggest a four-part cascade in which there is a reduction in the amount of dopamine released in a key reward area in the alcohol-preferring rats. The administration of substances that increase the supply of serotonin at the synapse or that directly stimulate dopamine D2 receptors reduce craving for alcohol (McBride et al. 1993). For example, D2 receptor agonists reduce the intake of alcohol among rats that prefer alcohol, whereas D2 dopamine-receptor antagonist increase the drinking of alcohol in these inbred animals (Dyr et al. 1993).
Support for the cascade theory of alcoholism in human beings is found in a series of clinical trials. When amino-acid precursors of certain neurotransmitters (serotonin and dopamine) and a drug that promotes enkephalin activity were given to alcoholic subjects, the individuals experienced fewer cravings for alcohol, a reduced incidence of stress, an increased likelihood of recovery and a reduction in relapse rates (Brown et al. 1990; Blum and Tractenberg 1988; Blum, Briggs and Tractenberg 1989). Furthermore, the notion that dopamine is the “final common pathway” for drugs such as cocaine, morphine and alcohol is supported by recent studies by Jordi Ortiz and his associates at Yale University School of Medicine and the University of Connecticut Health Services Center. These authors demonstrated that the chronic use of cocaine, morphine or alcohol results in several biochemical adaptations in the limbic dopamine system. They suggest that these adaptations may result in changes in the structural and functional properties of the dopaminergic system.
We believe that the biological substrates of reward that underlie the addiction to alcohol and other drugs are also the basis for impulsive, compulsive and addictive disorders comprising the reward deficiency syndrome.
An alteration in any of the genes that are involved in the expression of the molecules in the reward cascade might predispose an individual to alcoholism. Indeed, the evidence for a genetic basis to alcoholism has accumulated steadily over the past five decades. The earliest report comes from studies of laboratory mice by the American psychologist L. Mirone in 1952. Mirone found that, given a choice, certain mice preferred alcohol to water. Gerald McLearn at the University of California at Berkeley took this a step farther by producing an inbred mouse (the C57 strain) that had a marked preference for alcohol. The alcohol-preferring C57 strain bred true through successive generations-it was the first clear indication that alcoholism has a genetic basis (McLearn and Rodgers 1959).
The first evidence that alcoholism has a genetic basis in human beings came in 1972 when scientists at the Washington University School of Medicine in St. Louis found that adopted children whose biological parents were alcoholics were more likely to have a drinking problem than those born to nonalcoholic parents (Schuckit, Goodwin and Winokur 1972). In 1973 Goodwin and Winokur, working at the Psykologisk Institutin Copenhagen, studied 5,483 men in Denmark who had been adopted in early childhood. They found that the sons born to alcoholic fathers were three times more likely to become alcoholic than the sons of nonalcoholic fathers.
In the late 1980s research on the inheritance of alcoholism suggested that there might be important genetic differences between alcoholics and nonalcoholics (Cloninger, Bohman and Sigvardsson 1981; Goodwin 1979). One of us (Blum) and his colleagues suspected that the activity of the chemical signaling molecules in the reward pathways of the brain might be involved. Over the course of two years we compared eight genetic markers associated with various neurotransmitters (including serotonin, endogenous opioids, GABA, transferrin, acetylcholine, alcohol dehydrogenase and aldehyde dehydrogenase). In each instance we failed to find a direct association between the genetic markers and alcoholism.
The opportunity to investigate a ninth genetic marker arose after Olivier Civelli of the Vollum Institute at Oregon University cloned and sequenced the gene for one form of the dopamine D2 receptor. The D2 receptor is one of at least five physiologically distinct dopamine receptors (D1, D2, D3, D4 and D5) found on the synaptic membranes of neurons in the brain (Sibley and Monsma 1992). Previous studies had established that D2 receptors are expressed in neurons within the cerebral cortex and the limbic system, including the nucleus accumbens, the amygdala and the hippocampus. Because these are the same areas of the brain (with the exception of the cortex) that are believed to be involved in the reward cascade, Civelli’s work provided the opportunity to investigate an important molecular candidate for genetic aberrations among alcoholics.
The technique we used to distinguish between the D2 receptor genes of alcoholics and those of nonalcoholics relies on the detection of restriction-fragment-length polymorphisms (RFLPs). This approach involves the use of DNA-cutting enzymes (restriction endonucleases) that cleave the DNA molecule at specific nucleotide sequences. If there are genetic differences between two individuals such that a restriction enzyme cuts their DNA along different points in (or near) a gene, the resulting fragments of their genes will be of different lengths. These differing fragments, or polymorphisms, are recognized by the use of a radioactively labeled DNA probe-in this case a short sequence of the D2 receptor gene-that binds to a complementary DNA sequence on the fragments. Radiolabeled fragments of different lengths signify a difference in the cleavage sequence recognized by the restriction enzyme (Grandy et al. 1989).
The restriction enzyme (Taq 1) cuts the nucleotide sequence at a site just outside the coding region for the D2 receptor gene. This produces the Taq 1A polymorphisms. To date there are four Taq 1A alleles known, the A1, A2, A3 and A4 alleles. The A3 and A4 alleles are rare, whereas the A2 allele is found in nearly 75 percent of the general population and the A1 allele in about 25 percent of the population.
In 1990 we used the Taq I enzyme to search for TaqIA polymorphisms in the DNA extracted from the brains of deceased alcoholics and a control population of nonalcoholics. The results were striking: In our sample of 35 alcoholics we found that 69 percent had the A1 allele and 31 percent had the A2 allele. In 35 nonalcoholics we found that 20 percent had the A1 allele and 80 percent had the A2 allele.
Since our 1990 study, some laboratories have failed to find a connection between the A1 allele and alcoholism. However, a review of their work shows that their samples were not limited to severe forms of alcoholism, which we believe to be an important distinguishing criterion. In our original study, over 70 percent of the alcoholics had cirrhosis of the liver, a disease suggestive of severe and chronic alcoholism. Moreover, the negative studies failed to adequately assess controls to eliminate alcoholism, drug abuse and other related “reward behaviors.” In this regard, Katherine Neiswanger and Shirley Hill of the University of Pittsburgh recently found a strong association of the A1 allele and alcoholism and suggested that early failures were the result of poor assessment of a true phenotype in the controls (Neiswanger, Kaplan and Hill 1995). To date, 14 independent laboratories have supported the finding that the A1 allele is a causative factor in severe forms of alcoholism, though perhaps not in milder forms (Blum and Noble 1994). These findings do not prove that the A1 allele of the dopamine D2 receptor gene is the only cause of severe alcoholism, but they are a powerful indication that the A1 allele is involved with alcoholism.
Further evidence for the role of biology in alcoholism comes from efforts to find electrophysiological markers that might indicate a predisposition to the addictive disorder. One such marker is the latency and the magnitude of the positive 300-millisecond (P300) wave, an indicator of the general electrical activity of the brain that is evoked by a specific stimulus such as a tone. It turns out that abnormalities in the electrical activity of the brain are evident in the young sons of alcoholic fathers. Their P300 waves are markedly reduced in amplitude compared to the P300 waves of the sons of nonalcoholic fathers. These results raised the question as to whether this deficit had been transferred from father to son and whether this deficit would predispose the son to substance abuse in the future (Begleiter, Porjexa, Bihari and Kissin1984).
Experiments carried out since then have answered both questions. The alcoholic fathers had the same P300-wave deficit seen in their sons, and the sons showed increased drug-seeking behaviors (including alcohol and nicotine) compared to the sons of nonalcoholic fathers. Moreover, the sons of alcoholic fathers had an atypical neurocognitive profile (Whipple, Parker and Noble 1988). It now appears that children with P300 abnormalities are more likely to abuse drugs and tobacco in later years (Berman, Whipple, Fitch and Noble1993).
Remarkably, Noble and his colleagues found an association between the A1 allele and a prolonged latency of the P300 wave in children of alcoholics (Noble et al. 1994). Two of us (Blum and Braverman) extended this work and observed a similar correlation between the A1 allele and a prolonged P300 latency in a neuropsychiatric population. Subjects who are homozygous for the A1 allele showed significantly prolonged P300 latency compared to A1/A2 and A2/A2 carriers.
Cocaine can bring intense, but temporary, pleasure to the user. The aftermath is addiction and severe psychological and physiological harm. Various psychosocial theories have been advanced to account for the abuse of cocaine and other illicit drugs. In contrast to alcoholism, where growing empirical evidence is implicating hereditary factors, relatively little has been known about the genetics of human cocaine dependence. However, some recent studies have suggested that hereditary factors are involved in the use and abuse of cocaine and other illicit drugs.
Studies of adopted children, for example, show that a biological background of alcohol problems in the parents predicts an increased tendency toward illicit drug abuse in the children (Cadoret, Froughton, O’Gorman and Heywood 1986). Similarly, family studies of cocaine addicts show a high percentage of first- or second-degree relatives who have been diagnosed as alcoholics (Miller, Gold, Belkin and Klaher 1989; Wallace 1990).
Behavioral anomalies such as conduct disorder (in which children violate social norms and the rights of others) and antisocial personality (the adult equivalent of conduct disorder) are often found to be associated with alcohol and drug problems. Several investigators have noted that sociopathic behavior in children predicts a tendency toward antisocial personality behavior, alcohol abuse and drug problems later in life. An analysis of 40 studies showed a strong positive correlation between alcoholism and drug abuse, between alcoholism and antisocial personality, and between drug abuse and antisocial personality (Schubert et al. 1988).
Although there is little known about the genetics of cocaine dependence, extensive scientific data are available on the effects of cocaine on brain chemistry. The current view is that the system that uses dopamine in the brain plays an important role in the pleasurable effects of cocaine. In animals, for example, the principal location where cocaine takes effect is the dopamine D2 receptor gene on chromosome 11 (Koob and Bloom 1988). Recently George Koob and his colleagues of the Scripps Research Institute in La Jolla, California, found evidence suggesting that the dopamine D3 receptor gene is a primary site of cocaine effects. The exact effect of cocaine on gene expression is unknown. However, we do know that D2 receptors are decreased by chronic cocaine administration, and this may induce severe craving for cocaine and possibly cocaine dreams (Volkow et al. 1993).
A recent study by Ernest Noble of the University of California at Los Angeles and Blum found that about 52 percent of cocaine addicts have the A1 allele of the dopamine D2 receptor gene, compared to only 21 percent of nonaddicts. The prevalence of the A1 allele increases significantly with three risk factors: parental alcoholism and drug abuse; the potency of the cocaine used by the addict (intranasal versus “crack” cocaine); and early-childhood deviant behavior, such as conduct disorder. In fact, if the cocaine addict has three of these risk factors, the prevalence of the A1 allele rises to 87 percent. These findings suggest that childhood behavioral disorders may signal a genetic predisposition to drug or alcohol addiction (Noble et al. 1993).
A recent survey by the National Institute of Drug Abuse of five independent studies showed that the A1 allele is also associated with polysubstance dependence (Uhl, Blum, Noble and Smith 1993). The A1 allele is also associated with an increase in the amount of money spent for drugs by polysubstance-dependent people (Comings et al. 1994).
Although not viewed in the same light as the use of cocaine and other illicit drugs, cigarette smoking is another form of chemical addiction. Most attempts to stop smoking are associated with withdrawal symptoms typical of the other chemical addictions. Although environmental factors may be important determinants of cigarette use, there is strong evidence that the acquisition of the smoking habit and its persistence are strongly influenced by hereditary factors.
Of particular significance are studies of identical twins, which show that when one twin smokes, the other tends to smoke. This is not the case in nonidentical twins. In one twin study, Dorit Carmelli of the Stanford Research Institute and her associates examined a national sample of male twins who were veterans of World War II. A unique aspect of this study was that the twins were surveyed twice, once in 1967-68 and again 16 years later. This allowed an examination of genetic factors in all aspects of smoking-initiation, maintenance and quitting. In general, whatever happened to one identical twin happened to the other-including the long-term pattern of not smoking, smoking and then quitting smoking. The absence of these similarities in a control population of nonidentical twins suggests a strong biogenetic component in smoking behavior (Swan et al. 1990).
Animal studies have suggested that the dopaminergic pathways of the brain may be involved. For example, the administration of nicotine to rodents disturbs dopamine metabolism in the reward centers of the brain to a greater extent than does the administration of alcohol.
With this in mind, one of us (Comings) and his colleagues investigated the incidence of the A1 allele in a population of Caucasian smokers. These smokers did not abuse alcohol or other drugs, but had made at least one unsuccessful attempt to stop smoking. It turned out that 48 percent of the smokers carried the A1 allele. The higher the prevalence of the A1 allele, the earlier had been the age of onset of smoking, the greater the amount of smoking and the greater the difficulty experienced in attempting to stop smoking. In another sample of Caucasian smokers and nonsmokers, Noble and his colleagues found that the prevalence of the A1 allele was highest in current smokers, lower in those who had stopped smoking and lowest in those who had never smoked (Noble et al. 1994).
Obesity is a disease that comes in many forms. Once thought to be primarily environmental, it is now considered to have both genetic and environmental components. In a Swedish adoption study, for example, the weight of the adult adoptees was strongly related to the body-mass index of the biological parents and to the body-mass index of the adoptive parents. The links to both genetic and environmental factors were dramatic. Other studies of adoptees and twins suggest that heredity is an important contributor to the development of obesity, whereas childhood environment has little or no influence. Moreover, the distribution of fat around the body has also been found to have heritable elements. The inheritance of subcutaneous fat distribution is genetically separable from body fat stored in other compartments (among the viscera in the abdomen, for example). It has been suggested that there is evidence for both single and multiple gene anomalies (Bouchard 1995).
Given the complex array of metabolic systems that contribute to overeating and obesity, it is not surprising that a number of neurochemical defects have been implicated. Indeed at least three such genes have been found: one associated with cholesterol production, one with fat transport and one related to insulin production (Bouchard 1995). The ob gene and its product the leptin protein have also been implicated in regulating long-term eating behavior (Zhang et al. 1994). Most recently another protein, glucagon-like peptide 1 (GLP-1) has been found to be involved in the regulation of short-term eating behavior (Turton et al. 1996). The relationship between leptin and GLP-1 is not known. The ob gene may be involved in the animal’s selection of fat, but perhaps not in the ingestion of carbohydrates, which appears to be regulated by the dopaminergic system. It may be that the ob gene is functionally linked to the opioid peptodergic systems involved in reward.
Whatever the relation between these systems, the complexity of compulsiveeating disorders suggests that more than one defective gene is involved. Indeed, the relation between compulsive overeating and drug and alcohol addiction is well documented (Krahn 1991, Newman and Gold 1992). Neurochemical studies show that pleasure-seeking behavior is a common denominator of addiction to alcohol, drugs and carbohydrates (Blum et al. 1990). Alcohol, drugs and carbohydrates all cause the release of dopamine in the primary reward area of the brain, the nucleus accumbens. Although the precise localization and specificity of the pleasure-inducing properties of alcohol, drugs and food are still debated, there is general agreement that they work through the dopaminergic pathways of the brain. Other studies suggest the involvement of at least three other neurotransmitters serotonin, GABA and the opioid peptides.
Variants of the dopamine D2 receptor gene appear to be risk factors in obesity. The A1 allele was present in 45 percent of obese subjects as compared to 19 percent of nonobese subjects (Noble, Noble and Ritchie 1994). Furthermore, the A1 allele was not associated with a number of other metabolic and cardiovascular risks, including elevated levels of cholesterol and high blood pressure. In contrast, when the subject’s profile included factors such as parental obesity, a later onset of obesity and carbohydrate preference, the prevalence of the A1 allele rose to 85 percent. More recently another study found a significant association between genetic variants of the D2 receptor and obese subjects (Comings et al. 1993).
There is also an increased prevalence of the A1 allele in obese subjects who have severe alcohol and drug dependence (Blum et al. 1996a). When obesity, alcoholism and drug addiction were found in a patient, the incidence of the A1 allele rose to 82 percent. In contrast, the allele had an incidence of zero percent in nonobese patients who were also not substance abusers and did not have a family history of substance abuse. The presence of the dopamine D2 receptor gene variants increases the risk of obesity and related behaviors.
Pathological gambling-in which an individual becomes obsessed with the act of risking money or possessions for greater “payoffs”-occurs at a rate of less than two percent in the general population. Although it is the most socially acceptable of the behavioral addictions, pathological gambling has many affinities to alcohol and drug abuse. Clinicians have remarked on the similarity between the aroused euphoric state of the gambler and the “high” of the cocaine addict or substance abuser. Pathological gamblers express a distinct craving for the “feel” of gambling; they develop tolerance in that they need to take greater risks and make larger bets to reach a desired level of excitement, and they experience withdrawal-like symptoms (anxiety and irritability) when no “action” is available (Volberg and Steadman 1988). Indeed, there is a typical course of progression through four stages of the compulsive-gambling syndrome: winning, losing, desperation and hopelessness-a series not uncommon to other addictive behaviors.
Might the dopamine pathways in the brain be involved with pathological gambling? A recent study of Caucasian pathological gamblers found that 50.9 percent carried the A1 allele of the dopamine D2 receptor (Comings et al. 1996b). The more severe the gambling problem, the more likely it was that the individual was a carrier of the A1 allele. Finally, in a population of males with drug problems who were also pathological gamblers the incidence of the A1 allele rose to 76 percent.
This disorder is most commonly found among school-age boys, who are at least four times more likely to express the symptoms than are young girls. These children have difficulty applying themselves to tasks that require a sustained mental effort, they can be easily distracted, they may have difficulty remaining seated without fidgeting and they may impulsively blurt out answers in the classroom or fail to wait their turn. Although normal children occasionally display these symptoms, attention-deficit disorder is diagnosed when the behavior’s persistence and severity impedes the child’s social development and education. Early speculation about the causes of attention-deficit disorder focused on potential sources of stress within the child’s family, including marital discord, poor parenting, psychiatric illness, alcoholism or drug abuse. It has become progressively clear, however, that stress within the family cannot explain the incidence of the disorder. There is now little doubt that the disorder has a genetic basis.
Evidence in support of this notion comes from patterns of inheritance in the families of children with the disorder and from studies of identical twins. For example, consider instances in which full siblings and half-siblings (who have only half of the genetic identity of full siblings) are both raised in the same family environment. If the behavioral symptoms of attention-deficit disorder were “learned” in the family, then the incidence of the disorder should be the same for full siblings as it is for half-siblings. In fact, half-siblings of children with attention-deficit disorder have a significantly lower frequency of the disorder than full siblings (Lopez 1965). In another study, investigators found that if one identical twin had attention-deficit disorder, there was a 100 percent probability that the other also had the disorder. In contrast, the incidence of concordance among nonidentical twins was only 17 percent. This result has been supported by two other independent studies of identical twins (Willerman 1973). Finally, one of us (Comings) and his coworkers found that the A1 allele of the dopamine D2 receptor gene was present in 49 percent of the children with attention-deficit disorder compared to only 27 percent of the controls (Comings et al. 1991).
Some other recent work has linked attention-deficit disorder with another impulsive disorder: Tourette syndrome. More than 100 years ago the French neurologist Giles de la Tourette described a condition that was characterized by compulsive swearing, multiple muscle tics and loud noises. He found that the disorder usually appeared in children between 7 to 10 years old, with boys more likely to be affected than girls. Tourette suggested that the condition might be inherited.
In the early 1980s one of us (Comings) and his colleagues studied 246 families in which at least one member of the family had Tourette disorder. The study indicated that virtually all cases of Tourette syndrome are genetic (Comings et al. 1991). Subsequent studies also found that there was a high incidence of impulsive, compulsive, addictive, mood and anxiety disorders on both sides of the affected individual’s family (Comings and Comings 1987). The A1 allele was implicated in a recent report showing that nearly 45 percent of the people diagnosed with Tourette disorder carried the aberrant gene (Comings et al. 1991). Moreover, the A1 allele had the highest incidence among people who had the severest manifestations of the disorder.
As mentioned earlier, Tourette syndrome appears to be tightly coupled to attention-deficit disorder. In studies of the two disorders, it was found that 50 to 80 percent of the people with Tourette syndrome also had attention-deficit disorder. Furthermore, an increased number of relatives of individuals with Tourette disorder also had attention-deficit/hyperactivity disorder (Knell and Comings 1993). It now appears that Tourette syndrome is a complex illness that may include attention-deficit disorder, conduct disorder, obsessive, compulsive and addictive disorders and other related disorders. The close coupling between these disorders has led one of us (Comings) to propose that Tourette syndrome is a severe form of attention-deficit disorder (Comings and Comings 1989; Comings 1995).
The high frequency of the A1 allele among people with Tourette syndrome and attention-deficit disorder raises the question of whether other genes affecting dopaminergic function might also be involved in these disorders. Two others that have been considered are the gene for the enzyme dopamine B-hydroxylase, which converts dopamine to norepinephrine, and the gene for the dopamine transporter, which takes dopamine back into the presynaptic terminal after it is released into the synapse. In both cases, variant forms of these genes are associated with Tourette syndrome (Comings et al. 1996c). The anomalous dopamine B-hydroxylase gene (the “DBH Taq B1″ allele) was further associated with learning disabilities, conduct disorder and substance abuse, whereas the variant of the dopamine transporter (the “10 repeat” allele) was also associated with alcohol abuse, depression and obsessive-compulsive disorder. This observation was supported by other work showing that the 10 repeat allele for the dopamine transporter gene was associated with attention-deficit/hyperactivity disorder (Cook et al. 1995). Moreover, elevated levels of the dopamine transporter molecule have been found in the brains of patients with Tourette syndrome (Malison et al. 1995).
If these dopamine-related molecules are indeed associated with various behavioral disorders, it might be expected that having more than one variant would increase the severity or the likelihood of having a disorder. Indeed, this is the case: The severity of attention-deficit disorder, conduct disorder, substance abuse and mood disorders progressively increased from individuals carrying none of the genes to those who carried all three genes (Comings et al. 1996c).
Given the widespread prevalence of attention-deficit disorder among children, and its frequent association with alcoholism, drug dependence and other behavioral disorders, it may be that childhood attention-deficit disorder is a predisposing cause to various disorders among adults. For example, there is a significant correlation between attention-deficit hyperactivity disorder and adult drug abuse (Gittleman, Mannuzza, Shenker and Bonagura 1985).
The A1 allele carries a behavioral risk factor that shows up not only in substance addiction and attention-deficit disorder, but also in antisocial behavior, conduct disorder and violent or aggressive behavior. In a recent study the A1 allele was present in 60 percent of a sample population of young adolescents between 12 and 18 years old who were diagnosed as “pathologically violent” subjects (Blum Unpublished). A variant of the dopamine transporter gene (VENT 10 repeat) was present in 100 percent of the adolescents. Of these 70 percent had the so-called 10/10 form whereas 30 percent carried the 10/9 allelic form. Another study found that 59 percent of Vietnam veterans with post-traumatic stress disorder also carried the A1 allele, compared to only 5 percent of veterans who were exposed to similar stress but did not develop the disorder (Comings, Muhleman and Gysin 1996).
Why would carriers of the A1 allele be predisposed to the spectrum of disorders associated with the reward deficiency syndrome? Individuals having the A1 allele have approximately 30 percent fewer D2 receptors than those with the A2 allele (Noble et al. 1991). Since the D2 receptor gene controls the production of these receptors, the finding suggests that the A1 allele is responsible for the reduction in receptors. In some way that we do not yet understand, carrying the A1 allele reduces the expression of the D2 gene compared to carrying the A2 allele. Perhaps a regulatory site for the D2 receptor gene is affected in A1 carriers.
Fewer numbers of dopamine D2 receptors in the brains of A1 allele carriers may translate into lower levels of dopaminergic activity in those parts of the brain involved in reward. A1 carriers may not be sufficiently rewarded by stimuli that A2 carriers find satisfying. This may translate into the persistent cravings or stimulus-seeking behavior of A1 carriers. Moreover, because dopamine is known to reduce stress, individuals who carry the A1 allele may have difficulty coping with the normal pressures of life. In response to stress or cravings, A1 carriers may turn to other substances or activities that release additional quantities of dopamine in an attempt to gain temporary relief. Alcohol, cocaine, marijuana, nicotine and carbohydrates (like chocolate) all cause the release of dopamine in the brain and bring about a temporary relief of craving. These substances can be used singly, in combination or to some extent interchangeably.
Although we believe that the gene for the D2 receptor plays a critical role in reward deficiency syndrome, other genes (such as the dopamine transporter gene) are undoubtedly involved in the different manifestations of the syndrome. Scientists from Israel and the National Institute of Mental Health recently showed that a genetic variation of the dopamine D4 receptor gene is associated with people who are novelty (or sensation) seekers (Ebstein et al.1996 and Benjamin et al. 1996). Both studies set out to test the hypothesis advanced by Robert Cloninger of Washington University that novelty-seeking behavior is modulated by the way brain cells process dopamine. Richard Ebstein and his colleagues at the Herzog Memorial Hospital in Jerusalem found that novelty seekers-who tended to be compulsive, exploratory, fickle, excitable, quick-tempered and extravagant-were much more likely to have a longer version of the receptor gene than individuals who were not novelty seekers. Subjects with the shorter version of the gene scored lower on test of novelty seeking and tended to be reflective, rigid, loyal, stoic, slow-tempered and frugal. Jonathan Benjamin and his colleagues found similar results in their sample of 315 American subjects.
The work from the laboratories of Benjamin and Ebstein provide support of the earlier work of Susan George and associates at the University of Toronto who found a strong association between variants of the D4 gene and alcoholism and nicotine dependence. The D2 receptor gene and the D4 receptor gene have fairly similar nucleotide sequences and may have similar physiological functions. In this respect, it is intriguing that investigators at the University of California, Los Angeles found an association between the A1 allele and individuals who were classified as “sensation seekers” and were characterized by agitation, impulsivity, excitability and a “hot temper” (Compton et al. unpublished). All of these studies further support a connection between the reward deficiency syndrome and the dopaminergic system.
In the United States alone there are 18 million alcoholics, 28 million children of alcoholics, 6 million cocaine addicts, 14.9 million people who abuse other substances, 25 million people addicted to nicotine, 54 million people who are at least 20 percent overweight, 3.5 million school-age children with attention-deficit disorder or Tourette syndrome, and about 448,000 compulsive gamblers. We believe that recognizing the role of dopamine and the D2 receptor in the manifestation of these addictions and disorders is the first step toward rational treatment for a devastating problem in our society.
There is reason to believe that a pharmacological approach could help people with reward deficiency syndrome. It is tempting to speculate that the pharmacological sensitivity of alcoholics to dopaminergic agonists (bromocriptine, bupropion and n-propylnor-apomorphine) may be partly determined by the individual’s D2 genotoype. We predict that A1 carriers should be pharmacologically more responsive to D2 agonists, especially in the treatment of alcoholics or stimulant-dependent people. At least one study has already shown that the direct microinjection of the D2 agonist n-propylnor-apomorphine into the rat nucleus accumbens significantly suppresses the animal’s symptoms after the withdrawal of opiates (Harris and Aston-Jones, 1994).
A recent double-blind study demonstrates the utility of this approach in human subjects (Lawford et al. 1995). The D2 agonist bromocryptine or a placebo was administered to alcoholics who were carriers of the A1 allele (A1/A1 and A1/A2 genotypes) or who only carried the A2 allele (A2/A2). The greatest improvement in the reduction of craving and anxiety was found among the A1 carriers who were treated with bromocryptine. The attrition rate was highest among the A1 carriers who were treated with the placebo.
These findings provide an important rationale for DNA testing to detect genetic variants for the D2 receptor or other dopamine-related genetic variants in the tertiary treatment of alcoholism. Unlike certain other complex disorders, such as Alzheimer’s disease, the early identification and treatment of alcohol and drug abuse can occasionally alter the devastating course of these addictions. Consider the successes of self-help programs such as Alcoholics Anonymous and Narcotics Anonymous, psychopharmacological adjunctive therapy, neuroregulation or brain-wave training and electrophysiological stimulation. Identifying individuals with the A1 allele offers the possibility of helping individuals before alcoholism or substance abuse affect their lives. We foresee the possibility for better treatment, new forms of prevention and the removal of the social stigma attached not only to alcoholism but also to related “reward-seeking” behaviors comprising the reward deficiency syndrome.

A hammer toe is a joint deformity that occurs in the second, third or fourth toe. It is described as a hammer toe because the toe looks bent. If your toe is still flexible, you have a mild case of hammer toe. If your toe is rigid and hard to move, it is a more severe case of hammer toe.
What causes a hammer toe?
As is the case with most , a hammer toe usually is the result of shoes that are too tight. The constant pressure applied to your toes causes toes to bend over time. Basically, a hammer toe forms because your toes are cramped inside shoes for long periods of time. High heels, especially, can lead to hammer toes. Symptoms of a hammer toe include , corns and .
How can I treat a hammer toe?
If a hammer toe is not treated, it will only get worst. You can treat a hammer toe simply by choosing shoes that fit comfortably. This means that high heels, pointy shoes and shoes that are too narrow or short should be avoided so that your foot condition gets better. Apply non-medicated pads to the corns on your feet until they go away. Soaking your feet in warm water for 15 minutes daily will help to remove calluses. Toe exercises are also very helpful. Practice stretching your toes out or try picking items off of the floor with your foot. Depending on the severity of your hammer toe, you may have to go through physical therapy or undergo surgery. Find out what my favorite bloggers have to say about treating hammer toes:

With the typical Western diet being largely unhealthy, the incidences of digestive disorders continue to rise each year. Sometimes, traditional medical treatments do not sufficiently treat, or cure, these disorders. In other cases, people are simply looking for alternative treatments that do not involve taking medication. Acupuncture is an alternative treatment that has become increasingly popular for people who are suffering from a variety of conditions.
Acupuncture is a natural treatment process in which fine needles are inserted into designated points on the body. It is an ancient Chinese medical practice that is believed to help align our bodies and bring about homeostasis, or balance. In addition to providing overall balance and a sense of well being, acupuncture helps to stimulate our healing energies to improve organ function.
Traditional Chinese medicine promotes the belief that the spleen is the primary organ involved in gastrointestinal function. The reason for this is that the spleen is responsible for transporting food in the body and helping it to eliminate waste. When the balance between the spleen and the stomach is disrupted, gastrointestinal distress is likely to occur. This type of distress may also occur along with any disruptions to the function of the liver.
Acupuncture helps to bring about balance within the gastrointestinal system because the practice focuses on specific points on the body. By inserting needles just below the surface of the skin at precise locations, gastrointestinal muscle contraction helps to reduce gastric acid secretion, as well as promote relaxation, which collectively act to help alleviate digestive symptoms.
Generally, a combination of acupuncture and herbal medicine are used to treat digestive problems, but it is possible to obtain relief from digestive symptoms with acupuncture as a stand-alone treatment. If you do decide to try herbal medicine, make sure that you have a thorough exam and consultation with an acupuncture specialist so that you can discuss your health conditions, current medications, and any supplements that you may be taking. It is very important that you do this because some herbal treatments may interact negatively with over the counter and prescription drugs.
Acupuncture has been successfully used to treat the following types of digestive disorders:
Bacterial infections
Gastrointestinal infections
Gastrointestinal bleeding
Heartburn
Hiatal hernia
Inflammatory conditions (such as gastritis)
Inflammatory diseases (such as Crohn’s disease and ulcerative colitis)
Ulcers
There are a wide variety of other conditions that may be helped through the treatment of acupuncture. If you are suffering from a condition and you are seeking alternative, drug-free treatments, you might want to consider seeking the advice of a trained acupuncturist.
It is important that you thoroughly check the credentials of any acupuncturist that you are thinking about going to for treatment, however. You want to be sure that you enlist the services of a highly trained professional, preferably one who is trained in both Chinese and Western medicine. You can usually find out all of the information you need by conducting a search online. If you can not find out whether a practitioner is duly licensed or not, do not go to that person for treatment.

Are you suffering from a cold and at the same time have blisters present on your mouth , nose and lips? Well, you might have cold sores. It might not be a good sight to look at and it needs to be treated immediately. It is better to treat it at home away from other people. Isolating yourself from others would be a good idea since it will lessen the possibility that you will be spreading the cold sore. A home remedy for cold sore is needed, it usually last about two weeks but if it persists then that is the time to see a doctor.
Meanwhile since we can still use home remedy for cold sore, then we do it. Ice application is advised at the start of cold sores, applying it at least 5 minutes for each hour per day, you can do it alternately with a tea bag, a tea has antiviral properties. After which you can also apply a warm tea bag each hour for 20 minutes, you will see a change in a period of 5 days.
Diet also plays a role in providing remedy. Avoid foods that are acidic, high in arginine and salty. If you love drinking coffee then you better learn to decrease your consumption. Taking vitamins like folic acid and B12 can also help in strengthening and fighting off cold sores. Other applications with the use of salt, aloe vera and lemon can also help speed up the healing process.
You can also use witch hazel, a cornstarch paste, spirit of camphor may as well help. Apply it directly on the sore but of course you do not put everything at the same time. Consuming tea has its benefits as well, it is as good as direct application to the sore. Always wash your hands after touching your sore, avoiding contact with others who have no cold sore and always replace your toothbrush after each sore attack.
Home remedy for cold sore is easy to follow, but applying all of the above mentioned tips is not an assurance that you will be healed. If the symptoms persists after 2 weeks it is time for you to visit your doctor and have yourself checked. In this way, you will know what needs to be done and how you can put a stop to your cold sores.
Cold sores are red blisters that are usually present on the lips, mouth and nose. Although there are a lot of cures, remedies and treatments published about cold sores, well here are some of the best cures for cold sores that I can suggest. Usually if you have this, you have the symptoms of a cold plus the blisters present. Cold sores or fever blisters may not be good to look at, so here are a few cures to help you.
Everything starts with hygiene. Yes, make sure that you refrain from touching your sores and wash your hands always. This would prevent the spread of cold sores or further irritating it. Here are some of the best cures for cold sores. Remember not to cover them or conceal them, covering them with make up or concealer can further exacerbate or worsen the sore.
Do not let it dry. You can moisten it with a lip balm or a petroleum jelly. In this way, cracking, bleeding or drying of the sore can be prevented. When you are out in the sun, you can use a sunscreen to protect the sores from the sun’s rays. One of the products that you can use is tea, it contains tannic acid which has antiviral properties. Tea can be enjoyed by drinking or as compress.
You can also use herbs like aloe vera, sage, ginger and peppermint. Avoidance of foods rich in arginine can also help, examples of this are chocolate and nuts. If you think you will be better off with medications then ask your doctor about what medications you can use. It will also help if you know what are the triggering factors of cold sores. Fatigue as well as hormonal imbalances can contribute to the sores.
The best cure for cold sores is prevention. Knowing what triggers and causes it will help you avoid it. Staying away from it will help. Practice good hygiene and good hand washing. If you have a friend who has cold sores , it is better that you stay away from them, let them heal first for cold sores are contagious. Strengthen your immune system and keep yourself healthy.
