Abstract: | Studies of lymphocyte blastogenesis with peripheral blood cultures from patients suffering from non-coronary-related diseases of the myocardium revealed considerable impairments of its kinetics in the patients with myocarditis and dystrophic injury to the cardiac muscle. The ability of the peripheral blood lymphocytes to blastogenesis correlated with the severity of the clinical symptoms of the disease. Depression of the functional activity of short-lived suppressants was observed in patients with steady residual symptoms of nonrheumatic myocarditis. |
