作者对血压正常、中度和高度高血压病人组成的三组受试者,比较了基础状态下和在水平位上头部倾斜85°后的血浆垂体加压素的水平。A 组为无高血压史,舒张压≤85mmHg 的正常受试者;B 组为舒张压在90—109mmHg 的轻度和中度原发性高血压病人;C 组为舒张压≥110mmHg 的重度高血压患者。受试者四周内均未服用任何药物。用 Korotkoff Ⅰ和Ⅳ型血压计测量血压。受试者在实验前禁水、烟、酒12小时。仰卧休息60分钟,在电动手术床上被慢慢倾斜到头部水平位的85°,持续60分钟。分别于倾斜前5分,倾斜后15分、30分、45分、和60分钟由肘前静脉
The authors compared the plasma pituitary-vasopressin levels at baseline and at an incline of 85 ° in the basal state for three groups of subjects with normotensive, moderate, and high blood pressure. Group A is a normal subject with no history of hypertension and diastolic blood pressure <85mmHg; Group B is mild and moderate essential hypertension with diastolic blood pressure of 90-109mmHg; Group C has severe diastolic blood pressure <110mmHg Blood pressure patients. Subjects did not take any medication for four weeks. Blood pressure was measured with Korotkoff type I and type IV sphygmomanometers. Subjects in the experiment before the water, tobacco, alcohol 12 hours. Supine rest 60 minutes, in the electric operating bed was slowly tilted to the head level of 85 ° for 60 minutes. 5 minutes before tilting, 15 minutes after tilting, 30 minutes, 45 minutes, and 60 minutes from the antecubital vein
