虽然有许多技术可用以作肺部损害的临床估计,但多较复杂、昂贵和费时。近年来测定器官特异性酶的释放成为临床一种有用的诊断工具。如血浆肌酐磷酸激酶、乳酸脱氢酶同功酶可诊断心肌梗塞和心肌梗塞的范围。血浆血管紧张素转换酶(angiotensinconverting enzyme,ACE)则用于诊断肺部疾病。肺内ACE含量极高,主要位于内皮细胞,巨噬细胞和纤维母细胞含量则较少。肺的ACE能催活血管紧张素Ⅰ变成血管紧张素Ⅱ,使缓激肽灭活。
Although there are many techniques available to make clinical estimates of lung damage, they are more complicated, expensive and time-consuming. Determination of organ-specific enzyme release in recent years has become a clinically useful diagnostic tool. Such as plasma creatinine kinase, lactate dehydrogenase isoenzyme diagnosis of myocardial infarction and myocardial infarction range. Plasma angiotensin converting enzyme (ACE) is used to diagnose lung disease. High levels of ACE in the lungs, mainly in the endothelial cells, macrophages and fibroblasts content is less. Lung ACE can activate angiotensin Ⅰ into angiotensin Ⅱ, bradykinin inactivation.
