Abstract

In anaesthetized dog, right atrial stretch leads in the first five minutes to a decrease in plasma renin activity, when measured in inferior vena cava just above the renal veins. Bilateral cervical vagotomy increases plasma renin activity. After vagotomy, atrial stretch no longer has any effect on plasma renin activity. The results support the hypothesis of a control of renin secretion originating from atrial volume receptors.

摘要

在麻醉犬中，右心房扩张在最初五分钟会导致肾静脉上方下腔静脉中测得的血浆肾素活性降低。双侧颈迷走神经切断术会增加血浆肾素活性。迷走神经切断术后，心房扩张对血浆肾素活性不再有任何影响。这些结果支持了肾素分泌受心房容量感受器控制这一假说。
