strophanthin/inflammation

Effects of histamine and serotonin on strophanthine cardiotoxicity were examined in experiments on 312 cats. It was shown that inflammation mediators exert sympathomimetic action on the myocardium and potentiate strophanthine cardiotoxicity. These effects can be prevented by premedication with the

In isadrin-induced myocarditis, the rat heart shows an increase in the activity of acid phosphatase, glucose-6-phosphate dehydrogenase. The heart weight also rises, whereas ATPase activity and magnesium content fall. Under these conditions strophanthin produces a marked decrease in acid phosphatase

The results of these experiments permit a comparison of the action of strophanthin in the normal and the infected animals. In cats the percentage of deaths following the injection of 0.1 mg. of strophanthin per kilo of body weight was the same in normal and in pneumonic cats. The number of

The effect of various pathogenic factors and drugs on sensitivity to strophanthin and the possibility of pharmacoprophylaxis of toxicosis caused by this cardiotonic agent were studied in acute and chronic experiments on 375 cats. It is shown that impaired blood supply to the myocardium, toxic
