There are four kind of isoforms of endothelin in human and other mammals named ET-1, ET-2, ET-3 and ET-β, which are slightly different in construction and pharmacological effect. In human beings, ET-1 is the dominative subtypes. ET-1 remains in blood at a low level about 5ng per liter on physical state. It is synthesized, stored, released and metabolized locally. The half-life of ET-1 is about 1 hour. ET-1 is the most potent vasoconstrictive factor till now, and it is more functional in vein than in artery. In vascular bed, there are two kind of ET receptors. Type A mainly located in smooth muscle cells, whereas type B in endothelial cells. The latter can stimulate intimal hyperplasia via a parasecretion way and activate some oncogenes such as c-fos and c-myc and then enhance their expression. These alterations result in constriction of blood vessels, thus the SMC steps into proliferate state from silent state.
人及哺乳动物体内有四种结构及药理学性质略有差异的异物体,分别为ET-1、ET-2、ET-3、ET-β,而在人主要是ET-1,在生理条件下,ET-1在血浆中含量较低,约为5ng〓,故ET-1不是一个循环激素,而是局部合成释放,局部起作用的活性物质,半衰期约1小时,ET-1是目前已知的最强的血管收缩剂,对静脉的作用比动脉强,在血管床,ET受体有A、B两型,A型主要分布在平滑肌细胞,B型主要分布在内皮细胞,它可以通过旁分泌途径刺激内膜增生,具有有丝分裂原效应,可以激活某些癌基因如C-fos、C-myc使其表达增强引起血管收缩,使静止期SMC进入增殖期,还可以通过信号传导途径,与bFGF、GTF-β、PDGF等生长因子协同作用,起共有丝分裂原作用。

So researches reveal that HT could release the perimenopausal syndrome,protect Osteoporosis and Alzheimers disease which were resulted from low level of estrogen in the body. However, long term HT may increase the incidence rate of phlebothrombosis and breast cancer, and estrogen therapy without progestogen will increase the incident rate of endometrial carcinoma.
大量资料表明:HT可以缓解绝经女性体内雌激素水平低下导致的围绝经期综合征,预防骨质疏松及老年性痴呆的发病,但长期应用HT增加深静脉血栓形成及乳腺癌的发病风险,仅用雌激素治疗而不加用孕激素者子宫内膜癌发病率明显升高。
