[Regulatory properties of the rat heart adenylate cyclase in the course of toxic-infective shock caused by Yersinia pestis].
Influence of intravenously administered to rats murine toxin of Y. pestis in the dose of I mg/ml (LD100) on the regulatory properties of heart plasma membranes adenylate cyclase (AC) has been studied during the intoxication. It has been shown that basal, fluoride,- and 5-guanylyl imidodiphosphate-stimulated AC activity remained unchanged during the intoxication. Stimulation of AC by isoproterenol, glucagon and histamine did not change during the first two hours and significantly decreased after 5 hours of intoxication. Affinity of AC for the investigated hormones did not change through the experiments.
