Abstract

The effect of (+) IPNEA on various stimulant drugs was examined on isolated rat uterus. Addition of (+) IPNEA (1 times 10- minus 5 g/ml) to the organ bath, produced marked potentiation in the contractile responses of oxytocin and prostaglandins. Potentiation was less significant to 5-HT, vasopressin, angiotensin and bradykinin. (+) INPEA did not potentiate the responses of oxytocin on isolated rat mammary strip and the responses of prostaglandins on rat stomach (fundus) strip, guinea-pig tracheal chain and guinea-pig ileum. The significance of these findings has been discussed.

摘要

在离体大鼠子宫上研究了(+)异戊烯腺嘌呤对各种兴奋性药物的作用。向器官浴槽中加入(+)异戊烯腺嘌呤(1×10⁻⁵ g/ml)后,催产素和前列腺素的收缩反应出现明显增强。对5-羟色胺、血管加压素、血管紧张素和缓激肽的增强作用较小。(+)异戊烯腺嘌呤对离体大鼠乳腺条上催产素的反应以及前列腺素对大鼠胃(胃底)条、豚鼠气管链和豚鼠回肠的反应均无增强作用。已对这些发现的意义进行了讨论。
