In 29 patients with clinical diagnosis of rheumatic valvular disease the quantitative values of active rosettes and the specific sensitization to human heart myosin were examined. The specific sensitization to human heart myosin was examined by two methods concurrently: method of inhibiting leucocyte migration in agarose and method for direct specific lymphocytolysis with myosin. The results were compared with those of 44 clinically healthy controls. In the patients with rheumatic valvular disease (RVD) the values of the active rosettes are significantly lower (p less than 0.01) than in the healthy controls. With the method of direct specific lymphocytolysis with myosin statistically significant sensibilization of the lymphocytes to myosin was found in the patients with RVD (p less than 0.001). In 5 patients examined before and after operation it was established that 2-4 weeks after a successful correction of the hemodynamics the specific sensibilization of the lymphocytes to myosin was no more present.

In patients with various forms of ischemic heart disease the following indices were examined by radial immunodiffusion: alpha-1-acid glycoprotein, alpha-1-antitrypsin, haptoglobin, alpha-2-glycoprotein, beta-2-glycoprotein, immunoglobulin, C3 and C4 complement fractions. The changes in the serum glycoproteins during the acute phase of myocardial infarction are pointed out. The changes in the immunoglobulins and the complement fractions in patients with ischemic heart disease are discussed. Their determination in patients with stenocardia and past myocardial infarction is of no diagnostic value.

The changes in the basic hemdynamic indices and in the phase structure of the cardiac cycle in patients with acute infarction prior to and post treatment with beta-blockers (Obsidan and Trasicor) were studied. Manifested changes in the hemodynamics were established, namly: pulse rate and cardiac flow decrease, the total peripheral resistance grows; veloqcilty of blood flow is slowed down. The preparations used have a negative effect upon the phase structure of left ventricle as well. The authors underline that beta-blockers administration in acute myocardial infarction should be evaluated very carefully and in the presence of clinical signs for cardiac insufficiency, it should be carried out on the background of cardiotonic treatment.
