Alcohol flush reaction is a condition in which an individual develops flushes or blotches associated with erythema on the face, neck, shoulders, and in some cases, the entire body after consuming alcoholic beverages. The reaction is the result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol, and is caused by an acetaldehyde dehydrogenase deficiency. This syndrome has been associated with an increased risk of esophageal cancer in those who drink.〔(Alcohol Flush Signals Increased Cancer Risk among East Asians ) March 23, 2009 News Release - National Institutes of Health (NIH)〕 It has also been associated with lower than average rates of alcoholism, possibly due to its association with adverse effects after drinking alcohol. Because of the association with Asian ancestry, alcohol flush reaction has also been referred to by such informal names as Asian flush syndrome, Asian flush, and Asian glow. ==Signs and symptoms== Individuals who experience the alcohol flushing reaction may be less prone to alcoholism. Disulfiram, a drug sometimes given as treatment for alcoholism, works by inhibiting acetaldehyde dehydrogenase, causing a five to tenfold increase in the concentration of acetaldehyde in the body. The resulting irritating flushing reaction is intended to discourage alcoholics from drinking. For measuring the level of flush reaction to alcohol, the most accurate method is to determine the level of acetaldehyde in the blood stream. This can be measured through both a breathalyzer test or a blood test.〔http://www.criticalimprov.com/index.php/surg/article/viewArticle/982/〕 Additionally, measuring the amount of alcohol metabolizing enzymes alcohol dehydrogenases and aldehyde dehydrogenase through genetic testing can predict the amount of reaction that one would have. More crude measurements can be made through measuring the amount of redness in the face of an individual after consuming alcohol. Computer and phone applications can be used to standardize this measurement. Other effects include "nausea, headache and general physical discomfort".〔http://dujs.dartmouth.edu/fall-2009/esophageal-cancer-and-the-‘asian-glow’〕 Many cases of alcohol-induced respiratory reactions, which involves rhinitis and worsening of asthma develop in 1-60 minutes of drinking alcohol and are due to the same causes as flush reactions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「alcohol flush reaction」の詳細全文を読む スポンサード リンク
