Abstract

In 12 out of 32 non-insulin-dependent diabetic subjects, the activity of FAD-linked glycerophosphate dehydrogenase in T lymphocyte homogenates was abnormally low when measured by both a colonimetric and radioisotopic procedure. A comparable situation characterized by a deficient activity of FAD-linked glycerophosphate dehydrogenase in both the colonimetric and radioisotopic assays was only observed once among 26 other subjects including 11 healthy volunteers, 9 non-diabetic patients, 5 type-1 (insulin-dependent) diabetics, and 1 pancreatectomized diabetic. By analogy, it is speculated that an impaired activity of FAD-linked glycerophosphate dehydrogenase in the insulin-producing pancreatic B-cell could represent a far-from-uncommon contributive factor in the pathogenesis of non-insulin-dependent diabetes mellitus.

非胰岛素依赖型糖尿病是否可归因于fad相关甘油磷酸脱氢酶的缺乏?
在32名非胰岛素依赖型糖尿病患者中,12名患者的T淋巴细胞匀浆中fad连接的甘油磷酸脱氢酶活性异常低。在其他26名受试者中,包括11名健康志愿者、9名非糖尿病患者、5名1型(胰岛素依赖)糖尿病患者和1名胰切除术糖尿病患者,仅观察到一次fad相关甘油磷酸脱氢酶活性不足的类似情况。通过类比,我们推测胰岛素生成胰腺b细胞中fad连接的甘油磷酸脱氢酶活性受损可能是非胰岛素依赖型糖尿病发病机制中一个并不罕见的促成因素。
