Abstract

The paper deals with the influence of 1-(o-chlorophenyl)-1-(p-chlorophenyl)-2.2-dichloroethane (o,p'-DDD, chloditane) on NADPH-dependent reduction of cytochrome c, ferricyanide, 2,6-dichlorophenolindophenol and neotetrazolium; 156 and 312 mumol o,p'-DDD was added to the dog adrenal mitochondrial and microsomal suspension. Ferricyanide reduction decreased and neotetrazolium reduction increased under the influence of o,p'-DDD. Reduction of cytochrome c was inhibited in microsomal fraction and activated in mitochondrial one. o,p'-DDD exerted no influence on 2,6-dichlorophenolindophenol reduction in the adrenal subcellular fractions. The possible mechanisms of o,p'-DDD action on the electron transport system were discussed.

摘要

本文探讨了1-(邻氯苯基)-1-(对氯苯基)-2,2-二氯乙烷(邻,对'-滴滴滴,氯地孕酮)对细胞色素c、铁氰化物、2,6-二氯酚靛酚和新四氮唑NADPH依赖性还原的影响;向犬肾上腺线粒体和微粒体悬浮液中加入156和312μmol邻,对'-滴滴滴。在邻,对'-滴滴滴的影响下,铁氰化物还原减少,新四氮唑还原增加。微粒体部分中细胞色素c的还原受到抑制,而线粒体部分中细胞色素c的还原被激活。邻,对'-滴滴滴对肾上腺亚细胞部分中2,6-二氯酚靛酚的还原没有影响。讨论了邻,对'-滴滴滴对电子传递系统作用的可能机制。
