Reductions of cellular levels of myo-inositol results in the inhibition of the phosphoinositide cycle. Neurotrophic Factors
Various neurotrophic factors such as BDNF and mesencephalic astrocyte-derived neurotrophic factor have been shown to be modulated by various mood stabilizers. History
Lithium was first used in the 19th century as a treatment for gout after scientists discovered that, at least in the laboratory, lithium could dissolve uric acid crystals isolated from the kidneys. The levels of lithium needed to dissolve urate in the body, however, were toxic. Because of prevalent theories linking excess uric acid to a range of disorders, including depressive and manic disorders, Carl Lange in Denmark and William Alexander Hammond in New York City used lithium to treat mania from the 1870s onwards. By the turn of the 20th century, as theory regarding mood disorders evolved and so-called "brain gout" disappeared as a medical entity, the use of lithium in psychiatry was largely abandoned; however, a number of lithium preparations were still produced for the control of renal calculi and uric acid diathesis. As accumulating knowledge indicated a role for excess sodium intake in hypertension and heart disease, lithium salts were prescribed to patients for use as a replacement for dietary table salt (sodium chloride). This practice and the sale of lithium itself were both banned in 1949, following publication of reports detailing side effects and deaths.Also in 1949, the Australian psychiatrist John Cade rediscovered the usefulness of lithium salts in treating mania.
Alcohol intolerance  is due to a genetic polymorphism of the enzyme alcohol dehydrogenase, the enzyme that metabolises ingested alcohol. This polymorphism is most often reported in Asian patients. It can also be an effect or side effect associated with certain drugs such as disulfiram, metronidazole, or nilutamide. Stuffy nose and skin flushing are the most common symptoms when ingesting alcohol. It may also be characterized as intolerance causing hangover symptoms similar to the "disulfiram-like reaction" of aldehyde dehydrogenase deficiency or chronic fatigue syndrome. Severe pain after drinking alcohol may indicate a more serious condition.If people are intolerant, some non-alcoholic beverages may be a problem, similar to alcohol-containing medications, vinegar, inhalation of alcohol or the vapour of alcohol-containing cleaning agents.Drinking alcohol first or afterwards together with calcium cyanamide, an inorganic compound used as a fertilizer, can cause permanent or long lasting intolerance (nitrolime disease), contributing  together with other substances to the accumulation of harmful acetaldehyde by inhibiting the enzyme acetaldehyde dehydrogenase.
