山茛菪硷及川芎嗪对大鼠实验性肺水肿有明显预防作用,肺水肿病理生理的中心环节是肺泡一毛细血管膜的通透性增高。为了解肺水肿组与两预防组肺的通透性变化作如下实验:雌性健康大鼠40只,180～220g,每组10只分四组:1.对照组静注伊文思兰(Evan′s blue EB)50mg/kg,30′后处死。2.肺水肿组先静注EB,再注入肾上腺素 Anisodamine and ligustrazine have significant preventive effects on experimental pulmonary edema in rats. The central part of the pathophysiology of pulmonary edema is the increased permeability of alveolar-capillary membrane. In order to understand the pulmonary edema group and the two prevention group of lung permeability changes for the following experiment: 40 healthy female rats, 180 ~ 220g, each group of 10 divided into four groups: 1. Control group intravenous Evans blue (Evan ’ s blue EB) 50mg / kg, 30 ’after sacrifice. 2. Pulmonary edema group intravenous injection of EB, and then injected epinephrine
