    ABSTRACT: On the basis of earlier executed studies of hypotensive effect of dinitrosyl iron complexes (DNIC) with glutathione, the drug has been created in industrial conditions named oxacom. Preliminary pharmacological studies of oxacom have not revealed negative qualities. The drug has been now tested in 14 healthy men in whom at single intravenous introduction it caused typical response - a decrease of diastolic as well as systolic arterial pressure on 24-27 mmHg through 3-4 min with subsequent very slow restoration in 8-10 hours. The heart rate after initial rise was quickly normalized. Echocardiography revealed unaltered cardiac output in spite of reduced cardiac filling by 28%. The multilateral analysis of clinical and biochemical data has revealed an absence of essential alterations which could lead to pathological consequences. The drug is recommended for carrying out of the second phase of clinical trial. The comparative study of the efficiency of hypotensive action of oxacom, S-nitrosoglutathione (GS-NO) and sodium nitrite (NO2) in rats has shown that the duration of effect was the greatest at oxacom action.

    ABSTRACT: We studied morphological characteristics of platelets and parameters of platelet aggregation in patients with dilation cardiomyopathy. Augmented aggregatory activity of platelets was found in 76% of patients. In blood of majority of patients we found circulating leukocyte-platelet aggregates. This evidenced for development of inflammatory process and could be related to disturbances of blood rheology. In 2 patients examined by virusological method we revealed presence of a virus inside platelets. This phenomenon might serve as one of possible pathological pathways of disease progression at the account of spread of viral infection along vascular bed during thrombus formation.

    ABSTRACT: To study morphological features and functional activity of platelets, their relations with the level of inflammation markers in coronary heart disease (CHD) patients with depression. The study group consisted of 33 CHD patients with stable effort angina (NY-HA FC I-III), 14 had depression, 19 were free of depression. Sixteen healthy volunteers comprised the control group. Platelet aggregation was registered by a mean size of aggregates and turbidometrically. Platelets shape, leukocytic-thrombocytic and erythrocytic-thrombocytic aggregates (LTA, ETA) in the whole blood were studied electron-microscopically. The levels of IL-2, IL-6, TNF-alpha, sVCAM, hsCRP were measured in the blood, serotonin--in platelets. Spontaneous aggregation enhanced in 52.6% CHD patients (p < 0.05). The blood contained reticular platelets, high number of prothrombocytes (p < 0.05), mean volume of thrombocytes was greater (p < 0.05). This reflected changes in megakaryocytopoiesis. Some of the patients had LTA and ETA. Out of inflammation markers, only IL-6 and sVCAM were elevated (p < 0.01), hsCRP concentration rose, but not above normal range. Serotonin in platelets was the same in the patients and controls. Depression aggravated the disorders and elevated other indices. Spontaneous aggregation was high in 71.4% of depressive CHD patients. The count of reticular platelets, prothrombocytes, mean volume platelets were also elevated. LTA and ETA were high in all the depressive patients. Elevated were also concentrations of IL-6, sVCAM, IL-2, hsCRP. Serotonin in platelets was low (p < 0.05). Depression stimulates functional activity of platelets, is a factor of risk of intravascular inflammation and contributes to development of thrombotic complications in CHD patients.
