Abstract

The effect of cholinolytics inhibiting the transmission of signals in the cholinergic system on the rate of feeding reaction of juvenile carp Cyprinus carpio L. has been studied. We have revealed differences in the rate and duration of the impacts of cholinolytics affecting M- and N-cholinergic receptors on one of the parameters of the feeding behavior of fish: the rate of feeding reaction. The administration of the highest rate (1.0 mg/kg of fish weight) of some substances results in the maximal increase in the latent feeding time (or a decrease in the rate of the feeding reaction) of fish: by 710 and 224% in 1.5 h upon the use of atropine and metacin, respectively, and 249% in 30 min after pentamine administration. The period of return to the norm is 9 h for atropine and metacin and 8 h for pentamine. A decrease in the dose of all studied cholinolytics causes a dose-dependent decrease in the period of their action and in the feeding latent time. Different rates of the decrease in the rate of feeding reaction at the administration of cholinolytics of predominantly central (atropine) and peripheral (metacin and pentamine) effect testify to the dependence of this parameter on their effect on M- or N-cholinergic receptors.

溶胆素对鲤鱼摄食反应速率的影响。

摘要

cholinolytics的喂养的少年鲤鱼反应速率抑制胆碱能系统的信号传递中的作用鲤L.已被研究。我们已经揭示了影响M-和N-胆碱能受体的胆碱溶解剂对鱼类摄食行为参数之一的影响的速率和持续时间的差异：摄食反应速率。某些物质的最高添加量（1.0 mg / kg鱼重）的施用会导致鱼的潜在喂食时间最大增加（或喂食反应速率降低）：在1.5中增加710和224％戊胺给药后30 h分别使用阿托品和metacin，h分别为249％。阿托品和metacin恢复正常的时间为9小时，戊胺恢复为正常的时间8小时。所有研究的胆碱分解酶剂量的减少都会导致其作用时间和进食潜伏时间的剂量依赖性降低。
