摘要
采用微量注射法对大鼠侧脑室注入牛磺酸,观察对血压的影响。结果表明,①侧脑室注射牛磺酸可致血压明显降低,并呈现量效依赖关系,差异均有极显著性(P均<0.01);②侧脑室注射心得安可明显阻断牛磺酸的降压效应,而酚妥拉明对牛磺酸的降压效应无明显影响。提示侧脑室注射牛磺酸引起的降压效应与肾上腺素能β-受体的活动有关。
The effect and mechanism of taurine on blood pressure were investigated by microinjections into cerebroventricle of rats.The results were as follows:①Taurine injected decreased blood pressure and induced a dose-ependent relationship.②The depressor response of taurine could be antagonized by proprenolol,but not by phentolamine.The results show that the cardiovascular effects of taurine appears to be mediated β-adrenergically.
