大鼠高盐饮食可形成高血压,脑啡肽和β-内啡肽与心血管系统的功能调节有关,它也可能与高血压的发病机制有联系。本文目的,用我们实验室已建立的脑啡肽(EK)和血管紧张素Ⅱ(ATⅡ)的放射免疫分析法(RIA),观察大鼠长期高盐饮食对血压、ATⅡ和五个不同脑区EK含量的影响。 大鼠来源相同、雌雄不论,按年龄配对分成两组:1,高盐摄取组(47只),食物和饮水中食盐的浓度分别为7％,1％;2,对
High-salt diet in rats produces high blood pressure. Enkephalin and β-endorphin are related to the functional regulation of the cardiovascular system. It may also be related to the pathogenesis of hypertension. The purpose of this article is to use the radioimmunoassay (RIA) of the enkephalin (EK) and angiotensin II (ATII) established in our laboratory to observe the long-term high-salt diet in rats on blood pressure, ATII, and five different brain regions. Effect of EK content. Rats were of the same origin, whether male or female, divided into two groups according to age: 1, high salt intake group (47), food and drinking water concentration of 7%, 1%; 2,
