用荧光法测定111例正常人动脉血(其中23例同时测定静脉血)及9例闭塞性肺动脉高压病人动、静脉血中血管紧张素转换酶(ACE)活力。正常人动脉血中ACE活力高于静脉血(P<0.05);闭塞性肺动脉高压病人动、静脉血中ACE活力分别高于正常人动、静脉血(P<0.05)。
Fluorescence was used to measure the activity of angiotensin converting enzyme (ACE) in arterial and venous blood of 111 normal human subjects (including 23 venous blood samples simultaneously) and 9 patients with occlusive pulmonary hypertension. The ACE activity in arterial blood of normal people was higher than that of venous blood (P <0.05). The activity of ACE in arterial and venous blood of patients with occlusive pulmonary hypertension was higher than that of normal people (P <0.05).
