冠心病患者循环血中内皮细胞、内皮素和6－酮－前列环素F_（1a）的动态变化及意义

以循环内皮细胞（ＣＥＣ）作为血管内皮细胞（ＶＥＣ）损伤的指示物，以血浆内皮素（ＥＴ）和前列环素（ＰＧＩ２）反映ＶＥＣ的功能变化，对８５例冠心病患者与３０例正常人进行对比研究，并对５０例不稳定型心绞痛及２０例急性心肌梗塞进行了动态观察．结果表明：冠心病外周血中ＣＥＣ、ＥＴ明显升高（Ｐ＜０．００１），ＰＧＩ２明显下降（Ｐ＜０．００１），尤以不稳定型心绞痛和急性心肌梗塞更显著，与病情的严重程度相一致．提示冠心病ＶＥＣ损伤，以及它所分泌的内皮源性舒缩因子失平衡参与了冠心病的病理过程。

Effects of chronic U50,488H treatment on binding and mechanical responses of the rat hearts

The effects of chronic injection of U50,488H (trans-3,4-dichloro-N-[2-(1-pyrrolidinyl)cyclohexyl]benzeacetamidel++ +), a selective kappa opioid agonist, on the properties of the binding sites of tritiated U69593 [(5 alpha,7 alpha,8 beta)-(-)-N-methyl-N-(7-(1-pyrrolidinyl)-1-oxaspiro (4,5)dec-8-yl)benzeneacetamide], another selective kappa opioid agonist, and mechanical responses to U50,488H of the heart were studied. Rats received injection twice a day with U50,488H for 4 days. Binding studies on the crude membrane homogenates revealed that there was no change in maximum binding, but a significant increase in Kd after the treatment, indicating that the number of kappa binding sites remained unchanged whereas the affinity of the binding sites to kappa-agonist decreased. The study on the mechanical responses to U50,488H in the isolated perfused heart preparation showed that although the agonist at 10(-6) M caused MR2266 reversible reductions in heart rate and force of contraction as well as ventricular ectopic beat in the heart of rats in the control group, its effects were absent in the U50,488H-treated group, indicating the development of tolerance to the mechanical effects of U50,488H on the heart. The results indicate that the development of tolerance to the mechanical effects of a kappa-agonist after chronic treatment with the agonist was not accompanied by down-regulation, but only a slight and significant reduction in affinity of kappa binding sites in the rat heart.
