Abstract

The histochemical methods were used to study alkaline phosphomonoesterase of capillaries, glycosaminoglycanes of vascular walls, and tissular basophils of rat brain after local gamma-irradiation of the head with doses of 51.6-645 mC/kg. During the first minutes and hours after irradiation, the actively functioning capillary network lengthened and secretion of indolylamines by tissular basophils increased. It is assumed that the changes observed are compensatory.

摘要

采用组织化学方法研究了大鼠头部局部γ射线照射剂量为51.6 - 645 mC/kg后,其脑内毛细血管碱性磷酸单酯酶、血管壁糖胺聚糖及组织嗜碱性粒细胞的变化。照射后的最初几分钟和几小时内,活跃功能的毛细血管网延长,组织嗜碱性粒细胞的吲哚胺分泌增加。推测所观察到的变化是代偿性的。
