Peripheral administration of nicotinic receptor antagonists with a quaternary ammonium group (hexamethonium and chlorisondamine) did not prevent the development of seizures induced by systemic treatment with nicotine in the toxic dose. The Me3N+ group with stable positive charge inhibits transport of these compounds into the brain through the blood-brain(More)
Prenatal administration of the n-cholinolytic ganglerone to pregnant female rats at different periods of gestation was found to lead to long-term changes in sexual behavior in pubescent offspring: there was a reduced dynamic of acquiring sexual experience and a very low level of sexual activity, with significant impairment to the motivational and(More)
The data obtained have shown that prenatal exposure of pregnant rat females of 9-19-day pregnancy to N-cholinolytics as compared to M-cholinolytics produce long-term behavioural changes in pubescent rat progeny. Pubescent rat progeny had low dynamics of gaining sexual experience and decreased sexual activity with equal disturbance of motivation and coitus.(More)
The results of experiments on mice showed that some imidazole-4,5-dicarboxylic acid derivatives injected into lateral cerebral ventricles produce a dose-dependent convulsant or anticonvulsant effects, that is, possess the properties of partial NMDA receptor agonists. The most promising partial NMDA receptor agonist selected for further investigation is(More)
The pyrogenic potential of natural and recombinant human IL-1 beta in rabbits was found to be very similar when the substances were given intravenously. Under these conditions, stabilization of rIL-1 beta with human serum albumin (HSA) failed to affect the pyrogenic activity of recombinant IL-1 beta. When the two preparations were administered directly into(More)
