本文研究了影响依色林对大鼠升压作用的几项因素。预先给予蛇根硷经常能抑制或取消依色林的升压反应。正肾上腺素,二羟基苯丙氨酸或者5羟基色胺的缓慢静脉灌注对预先给予蛇根硷的大鼠只能偶尔恢复依色林的升压作用。伯利特林(Bretylium)和溴化2,6-二甲苯乙醚胆硷(Cboline 2.6-xylyl ether bromide)能显著地减低甚至取消依色林的升压作用;前者的作用更强于后者。可卡因能对抗伯利特林影响依色林的作用。伯利特林在显著减低依色
This article studies several factors that affect the effect of icrin on rats. Snakehead alkaloids can often inhibit or cancel the vasopressin response. Slow intravenous infusion of norepinephrine, dihydroxyphenylalanine or 5-hydroxytryptamine only occasionally restored the ochrine-boosting effect on rats administered snakene. Bretylium and Cboline 2.6-xylyl ether bromide significantly reduced or even abolished the step-up effect of emeraldine; the former was more effective than the latter. Cocaine can counter the effect of beitrin on ezine. Buritelin significantly reduces the color by
