Studies on the Experimental Myocarditis by Tubercle Bacillus(IV)

Abstract

The clinical Observations of the Second Experiment. Sensitizing rabbits by the intravenous and intratesticular inoculation of tubercle bacilli with the rabbit-heart-muscle-phosphatide, I injected the same again 9 weeks after I found the tubercle interdermal reaction proved positve even it diluted to 10^<-9>. The clinical observations are as follows: 1) Body temperature, body weight, blood pressure and blood picture gave me almost the same results as the first experiment, though rather weak. 2) In electrocardiogram, after the second injection, T_2 showed conspicuous elevated and T_2, T_3 showed declined or inverted, therefore this experiment made me suppose the existence of severe myocardial demage.
