摘要: 目的与方法 研究17β-雌二醇(E2)对KCl和5-羟色胺(5-HT)引起离体猪基底动脉收缩的拮抗及保护作用。结果 E2浓度依赖性地对抗KCl引起的最大收缩作用,IC50为10-4.8mol/L。E2预处理后,浓度依赖性地抑制KCl引起的最大收缩,IC50为10-4.8mol/L,并降低5-HT引起收缩的浓度效应曲线的最大反应,其pD2'为4.57。结论 E2对离体猪基底动脉有舒张作用。

关键词: 17β-雌二醇, 猪基底动脉, 5-HT

Abstract: Aim and Methods The relaxing and inhibitory effects of 17β-estradiol(E2)on KCland 5-HT induced contraction of isolated pig basilar arteries were observed.Results After incubation with E2(10-5,10-4.2mol/L),the phasic contract ion induced by KCl was inhibited in a concentration-dependent manner in artery rings(IC50was10-4.8mol/L),and the concentration effect curve generated by 5-HT was also inhibited (pD2'was4.57).Conclusion E2 has vasodilatory effect on isolated pig basilar arteries.

Key words: 17β-estradiol, isolated pig basilar arteries, 5-HT
