[The prostaglandin and cyclic nucleotide levels in the organs of mice with experimental anthrax intoxication].

In this work the influence of Bacillus anthracis toxin, introduced intraperitoneally in a dose of LD100, on the content of prostaglandins E and F2 alpha, 6-ketoprostaglandin F1 alpha, thromboxane, cAMP and cGMP in the lungs, heart, liver and spleen of BALB/c mice in the time course of experimental intoxication has been studied. The concentration and proportion of prostaglandins and cyclic nucleotides have been shown to undergo-sharp changes in all organs under study in the process of intoxication. The level and proportion of prostaglandins in the lungs ensures the development of vaso- and bronchodilatation processes even at early stages of the action of the toxin. B. anthracis toxin sharply increases the content of cGMP in the organs under study and cAMP in the liver. The activating effect on the adenylate cyclase system of tissue cells is not linked with the action of the edematous factor of the toxin. The role of cyclic nucleotides and prostaglandins in the development of pulmonary edema in intoxication with B. anthracis toxin is discussed.
