| 摘 要： | 在微量注射大量肝脏ｍＲＮＡ之后，通过电压箝方法进行功能鉴定，两栖类卵母细胞成功地表达了ＡＶＰＶ１ａ受体。但在灌流ＡＶ４－８溶液时，却不能诱导卵母细胞产生内向振荡电流反应。提示ＡＶＰ４－８不能通过ＡＶＰＶ１ａ受体而介导生理学效应。

| Abstract: | The AVP V1a receptors can be expressed and functionally identified by the voltage-clamp method in amphibian oocytes after injection of rat liver mRNA.AVP4-8 is a segment of AVP and improve learning and memory markedly in the rat. This work is to investigats the action of AVP4-8 on the V1a receptors in oocytes. When AVP4-8 was bath-applied to the oocytes,no inward membrane current could be elicited. The data showed that AVP4-8 can not mediate physiological effect through AVP V1a receptors. |
