renin

1.Sympathetic innervation of the juxtaglomerular apparatus in the kidney releases renin;

肾脏肾小体的交感神经支配释放肾；

2.The intracytoplasmic renin containing granules in Juxtaglomerular Cell Tumor are PAS+e, diastase-resistant.

细胞瘤细胞的胞浆内肾颗粒PAS染色阳性。

3.Renin, a proteolytic enzyme formed in the granules of the juxtaglomerular apparatus cells, catalyzes conversion of the protein angiotensinogen to angiotensin I, a decapeptide.

肾是肾小体细胞颗粒内形成的一种蛋白水解酶，催化蛋白血管紧张原转换为血管紧张Ⅰ，即十肽。

4.Conclusion: The changes of circadian variation of blood pressure are associated with the role of sympathetic nerve and intracardial renin angiotensin system.

结论血压昼夜变化受交感神经与肾血管紧张系统等双重作用有关。
