[The hormone level of the blood from the aorta and the coronary sinus in patients with ischemic heart disease under conditions of preoperative stress].

A total of 156 patients with ischemic heart disease were examined under conditions of preoperative stress in a multiple-modality study performed with the aid of such techniques as echocardiography involving calculation of the myocardial mass index, coronaroventriculography, measurements of the adrenocorticotrophic hormone, hydrocortisone, somatotrophic hormone, triiodothyronine and thyroxin in the blood from the coronary sinus and aorta. A conclusion has been reached that emotional strain influences myocardial hypertrophy. A possible significance of the studied hormonal indices is shown together with features thereof in IHD patients presenting with different degrees of left ventricular hypertrophy.

[Immunologic aspects of renal involvement in patients with type II diabetes mellitus].

Besides the known factors contributing to the pathogenesis of diabetic nephropathy, the role of immune mechanisms in types I and II diabetes is discussed of late; the contribution of autoimmune mechanisms to pathogenesis of noninsulin-dependent diabetes (NIDDM) is virtually unknown. Seventy-six patients with NIDDM and 48 with insulin-dependent condition were examined. Under study were levels of antibodies to FxIA and renal glomerular basal membrane antigens in the blood sera of donors and patients with types I and II diabetes, as well as concentrations, size, and pathogenicity of immune complexes.

[The vasospastic component in the pathogenesis of unstable angina].

A comprehensive dynamic investigation revealed a group which included 31 (9.8%) patients with a response to the introduction of a probe-electrode during transesophageal pacing. It was characterized by ST-segment elevation and development of an anginal attack.
