Abstract

Neutral alpha, 1-4 glucosidase activity was assayed by a spectrophotometric method using p-nitro-phenyl-alpha-D-glucopyranoside as the substrate in the seminal plasma of normal, vasectomized, and oligospermic men. The latter groups showed lower values than the controls. These results suggest that the main source of the alpha, 1-4 glucosidase activity is between the vasectomy site and the tubule, and that the enzyme is related to sperm density or to a spermatogenesis factor.

摘要

采用分光光度法，以对硝基苯基-α-D-吡喃葡萄糖苷为底物，对正常男性、输精管结扎男性和少精子症男性的精浆中的中性α-1,4-葡萄糖苷酶活性进行了测定。后两组的数值低于对照组。这些结果表明，α-1,4-葡萄糖苷酶活性的主要来源在输精管结扎部位与小管之间，并且该酶与精子密度或生精因子有关。
