乙醇脱氢酶(ADH)同工酶与肝脏的不同,在人的胃粘膜中存在。在所研究的所有7名黑人和11名白人美国人的手术标本中,胃粘膜中存在两条ADH活性条带,其中14例缺失,21名日本受试者中有3例几乎检测不到。类似的种族差异与性别有关,与胃部病理无关。这些酶带在淀粉凝胶电泳法上的迁移率与最近报道的μ-adh或σ-adh一致。这些酶带的缺失与还原亚硝基苯甲醛的能力下降了70%有关,后者是σ-ADH的首选底物,这表明日本人胃中缺失的酶带包括这种同工酶。
Alcohol dehydrogenase (ADH) isoenzymes different from these of the liver were shown to be present in the human gastric mucosa. Two ADH activity bands present in the gastric mucosa of surgical specimens from all 7 black and 11 white Americans studied were absent in 14 and barely detectable in 3 of 21 Japanese subjects evaluated. Similar ethnic differences pertained to both genders and were independent of the gastric pathology. The mobility of these bands on starch gel electrophoresis corresponded to those recently reported and named μ-ADH or σ-ADH. The absence of these bands was associated with a 70% decreased capacity to reducem-nitrobenzaldehyde, a preferred subtrate for σ-ADH, suggesting that the bands missing from the Japanese stomachs comprise this isoenzyme.
