为了探讨肾素活性(PRA)和血管紧张素Ⅱ(AT-Ⅱ)在低氧性肺动脉高压中的作用,我们按钟南山方法作实验性低氧性(猪)动脉模型。低氧前后收集主动脉弓和肺动脉血,进行PRA和AT-Ⅱ的测定。材料及方法1.低氧通气前(3小时)和
To investigate the role of renin activity (PRA) and angiotensin II (AT-II) in hypoxic pulmonary hypertension, we conducted an experimental hypoxic (porcine) arterial model by Zhong Nanshan method. Aortic arch and pulmonary arterial blood were collected before and after hypoxia for the determination of PRA and AT-II. Materials and methods 1. Before hypoxia (3 hours) and
