一种新型的生物瓣材料—Ⅹ.牦牛心包中部分酶的组织化学观察

An Observation of 15 Enzyme Histochemistry in Yak Pericdarum

本文通过对九只(3～9岁)正常牦牛心包的心前区进行光镜酶组织观察,得知:(1)3～9岁牦牛心包的超微结构有差异,但酶的活性与年龄无关;(2)除AKP酶外,其余14种酶的活性一般规律是,问皮细胞的活性大于纤维细胞的活性;(3)间皮细胞和纤维细胞的代谢特点以糖酵解为主。

Histochemical studies of normal anterior parietal pericardium derired from nine yaks (3-9 years old) revealed that: (1) the activity of 15 enzymes does not appear to be related to age (3-9 years old), although a small ultrastructural difference could be seen. (2) the activity of most enzymes in mesothelial cells is higher than that in fibrocytes, except AKPase and ATPase, which suggests that the metabolic actvity is greater in the mesothelial cells. (3) the main metabolic feature of the mesothelial cells and the fibrosa is anaerobic degradation.
