(二)肾素-血管紧张素活动增强及其他机理有许多因素和条件可以影响肾脏分泌肾素:在妇女妊娠期血浆肾素活性(ARP)增高,月经周期的黄体期,由于孕酮的作用,血浆肾素活性也增强,口服避孕药也有同样的作用。ACTH,前列腺素(PGE)能刺激肾素分泌,这种作用受体内的离子负荷影响;正常人食物中K~+过多可使血浆肾素活性下降,而缺钾则使肾素活性增强;在肾动脉内注入含高钾的溶
(B) of the renin - angiotensin activity and other mechanisms to enhance a number of factors and conditions can affect the secretion of renin in the kidney: women in pregnancy plasma renin activity (ARP) increased menstrual cycle luteal phase due to the role of progesterone , Plasma renin activity also increased, oral contraceptives have the same effect. ACTH, prostaglandin (PGE) can stimulate renin secretion, this effect is affected by the ion load in the body; normal human food K ~ + too much plasma renin activity decreased, while potassium is renin activity increased ; In the renal artery into the solution containing high potassium
