Abstract

It was established in experiments on unanesthetized rats given intraventricular injections of drugs that hyperthermic effect of prostaglandin E2 (PGE2) was markedly weakened by administering clofelin while isoproterenol had no appreciable effect on PGE2 effects were not prevented by noradrenaline, 5-hydroxytryptamine, phenoxybenzamine, propranolol, deseril, nicotine, metamyzyl and IEM-506. Preliminary administration of oxotremorine and hemicholinium-3 averted PGE2 effect. The disorders of the thermo-regulation centers caused by excess PGE2 are likely to be counterbalanced by the central effect of some synaptically active drugs which affect in particular the function of cholinergic synapses and alpha-adrenoreceptors.
