[Effects of fibronectin instillation on reparative regeneration of the corneal tissue (an experimental study)].

Comprehensive morphologic studies (including light microscopy, morphometry, autoradiography) of experimental rabbits have revealed a stimulating effect of fibronectin instillations on healing of central penetrating wounds of the cornea. A polypotent mechanism of the stimulating effect of fibronectin instillations during all the stages of the reparative process in the corneal tissue was proved.

[Impairment of glucose metabolism and changes in insulin activity during open heart surgery].

The examination of 147 surgical patients with cardiac diseases revealed that the onset of an operative intervention (skin incision) was accompanied with a substantial rise in endogenous insulin antibody titers in the blood of the operated patients, which is likely to trigger glucose metabolic disturbances. Insulin, 0.8-1.0 U/(kg/hour), and glucose, 0.4-0.5 g/(kg/hour), therapy (IGT) initiated prior to the skin incision and continued up to the application of forceps to the aorta was found to prevent the increase in insulin antibody titers both during the surgery and within 16-18 hours of the nearest postoperative period. IGT was demonstrated to improve myocardial contractility of patients in the preperfusion period and to provide an additional protection of the heart during its temporary anoxia. Insulin synthetic processes were activated in the nearest postoperative period in patients receiving IGT, unlike patients from the control group, the latter showing signs of diminished functional activity of B cells in the pancreas along with a moderate enhancement in the titer of antibodies to endogenous insulin. It was concluded that intraoperative IGT is a pathogenetically substantiated therapeutic modality in the complex of anesthetic supply during open heart surgeries.

[Solid-phase immunoenzyme method of determining myoglobin in the diagnosis of acute myocardial infarction].

A solid-phase immunoassay was developed for quantitative estimation of myoglobin in human biological fluids. This technique was used for analyses of blood serum and plasma from patients with acute myocardium infarction. The method developed was similar to radioimmunoassay by its diagnostic characteristics but more simple and available. The immunoassay might be used in diagnosis of myocardium infarction as well as in estimation of the disease severity at least in clinics.

[A solid-phase immunoenzyme method of the quantitative determination of insulin antibodies].

A test system for quantitative estimation of antibodies towards insulin was developed using the solid phase immunoenzymatic procedure. The test system was calibrated using affinity antibodies towards insulin, obtained after immunosorption of blood plasma of insulin-resistant patient with diabetes. The normal content of autoantibodies, estimated by means of the procedure in human blood serum, constituted 35.2 X 10(-3) +/- 12.4 X 10(-3) g/l. In the patients with diabetes increased content of autoantibodies towards insulin was usually determined--70 X 10(-3)-180 X 10(-3) g/l.

[Quantitative immunoenzyme determination of fibronectin in biological fluids].

Quantitative immunoenzyme assay of fibronectin in blood plasma is developed. Isolation and purification of fibronectin from human blood plasma, harvesting of specific antibodies to fibronectin, production of the antibodies and peroxidase conjugates and step-by-step procedure of the immunoenzyme assay in a "sandwich" modification are described. The assay was applied for diagnostics of several infectious and somatic diseases.

[Erythrocyte equidistance and heavy metals in the pathogenesis of disseminated intravascular coagulation in myocardial infarct patients at the hospital rehabilitation stage].

Blood levels of fibrin degradation products and free haemoglobin were studied in 108 inpatients with acute transmural myocardial infarction in the period of rehabilitation. At the same time contents of cadmium, vanadium, lead and nickel in blood cells and plasma were determined spectrographically. It was established that heavy metals take part in activation of blood clotting and haemolysis which decrease equidistance and accelerates sedimentation of erythrocytes.
