中国生理学会第２０届理事会工作报告

中国生理学会第２０届理事会于１９９８年９月２１日在江西省庐山召开的全国会员代表大会上经选举后成立。理事会成立至今已近四年,在中国科协和卫生部领导的关怀、支持和帮助下,我们认真贯彻执行中国科协学会作为“学术交流主渠道,科普工作主力军”等的各项指示,遵照本会会章的规定,成功地组织和开展了一系列活动,取得了比较好的成绩,得到了广大会员的赞许,有些工作还曾得到科协领导的多次表扬。以下是我受本届理事会、杨雄里理事长的委托,向学会第２ｌ届会员代表大会提出的理事会工作报告,请大家审议。

K—阿片受体拮抗剂MR—2266—BS对ACTH和催乳素释放的影响

The effect of intravenous injection of different doses of MR-2266-BS, a selective antagonist of kappa-opiate receptor, on plasma adrenocorticotropin (ACTH) and prolactin (PRL) in conscious male rats bearing an intrajugular cannulae was assessed. The results revealed that the MR-2266-BS of 3 mg/kg completely blocked the restraint stress-induced increase in plasma ACTH levels, and further elevated plasma PRL levels in these animals, while there were no effects on the resting levels of ACTH and PRL. MR-2266-BS of 6 mg/kg significantly increased the resting levels of plasma ACTH and also further elevated the restraint stress-induced increase of plasma ACTH and PRL. The present data suggest that kappa-opiate receptor and its endogenous ligand may be involved in the regulation of the resting and restraint stress-induced release of ACTH, and their action appears to be both stimulatory and inhibitory. Furthermore, kappa-opiate receptor and its endogenous ligand may only inhibit the stress-induced release of PRL.
