肾素血管紧张素系统（RAS）是心血管系统体内平衡的调节机制之一，在许多疾病的病理生理中起着重要作用。血管紧张素11（Aug11）是IthS中主要的活性肽，目前所知的RAS的效应，大多通过Angll的各种生理作用表现出来，如：收缩血管，导致血压升高和后负荷增加；刺激醒固酮释放， The renin-angiotensin system (RAS) is one of the regulatory mechanisms of cardiovascular homeostasis and plays an important role in the pathophysiology of many diseases. Angiotensin 11 (Aug11) is the major active peptide in IthS. The effects of RAS so far known are mostly manifested by various physiological effects of Angll, such as: vasoconstriction, leading to increased blood pressure and postload; Tone release,
