[Immunologic autoagression in patients with diabetic retinopathy under type I diabetes mellitus].

Presence of IgG autoantibodies to broad spectrum of tissues' antigens in patients with diabetic retinopathy under type I diabetes mellitus was studied. Increased levels of antibodies to different antigens were observed in 56% of patients. Increased levels of antibodies to hypophysis, denaturated DNA, and myelin basic protein were detected most frequently.

[Systemic autoantibodies and their correction in patients with diabetic retinopathy in type 1 diabetes mellitus].

Examination of 91 patients with diabetic retinopathy in the presence of type I diabetes mellitus (DM-1) showed that 56% of the patients had a great variety of organ-specific and organ-nonspecific autoantibodies (AABs), including those to the microsomal and cytoplasmic fractions of endocrine glands, such as pancreas, thyroid, and pituitary. AABs were most common to the pituitary (23.2%), total myelin protein (18.

[Alterations in the functional activity of platelets in patients with angina pectoris during the cold test].

The functional activity of platelets was examined in patients with coronary heart disease and healthy individuals during cold test (CT). Patients prone to vasospastic responses to CT exhibited platelet activation along with beta-thromboglobulin release and formation of spontaneous platelet aggregates. Comparison of functional changes in platelet functional activity which occurred during cold test and intravenous ergometrine test suggest that the response to CT may be substantially higher if platelet aggregability is concurrently determined.
