血管紧张素转化酶(Angiotensin con-verting enzyme,简称ACE)是具有血管收缩作用的酶,1978年,Gronhagen-R-iska等人、Dandvea等人和日本的四元等人曾报道矽肺病人血清中ACE活性增强,然而ACE活性增强与矽肺病的进展程度、暴露于粉尘的历史及其他病人方面因素的关系,详细分析报道者罕见,其结果也不一致。因此,作者们对许多矽肺病人的血清 Angiotensin con-verting enzyme (ACE) is an enzyme with vasoconstriction. In 1978, Gronhagen-R-iska et al., Dandvea et al. And Japan’s Quaternary et al. ACE activity increased, however, ACE activity increased with the degree of progression of silicosis, the history of exposure to dust and other patient factors, the detailed analysis of the report were rare, the results are inconsistent. Therefore, the authors of the sera of many patients with silicosis
