[The kallikrein-kinin system of blood in hypertensive crises in hot climate]. / Kallikrein-kininovaia sistema krovi pri gipertonicheskikh krizakh v usloviiakh zharkogo klimata.

The values of depressive humoral factors drastically decrease in healthy subjects and patients with hypertensive disease running with crisis in the areas of hot climate in summer. After arresting hypertensive crises, the levels of kallikreinogen, kallikrein, kininogen increase. In the crises, there is a significant inverse correlation between the blood pressure and blood kallikrein and kininogen concentrations. The values of kallikrein-kinin system components clearly characterize the clinical status of patients with hypertensive disease running with crisis and are of predictive value for clarification of the body's protective reserves.

[Eicosanoids in chronic liver diseases]. / Eikozanoidy pri khronicheskikh zabolevaniiakh pecheni.

The results could be contributing to diagnosing and treating chronic inflammation in the liver.

[Study of the calmodulin-dependent regulation of calcium adenosine triphosphatase of erythrocyte membranes in patients with ischemic heart disease]. / Issledovanie kal'modulinzavisimoi reguliatsii Ca-ATFazy membran éritrotsitov bol'nykh ishemicheskoi bolezn'iu serdtsa.

The inhibitor calmodulin (R 24571) was examined for effects on the activity of red blood cell Ca-ATPases in patients with coronary heart disease during the treatment with nitrates, beta-blockers and calcium antagonists. The maximum activity of Ca-ATPase was measured in the erythrocytes perforated with saponine in the presence of endogenous regulators at a concentration of Ca2+ of 3-5 microM. Patients with high and low Ca-ATPase activity were identified. In the control group R24571 failed to affect Ca-ATPase activity. In patients, the calmodulin inhibitor caused both Ca-ATPase activation and inhibition. The effects of R 24571 correlated with the severity of the patients' condition. In effective therapy, the action of the calmodulin inhibitor became lower on Ca-ATPase activity. It was concluded that there was Ca-ATPase regulation imbalance in patients with coronary heart diseases.

[The clinical manifestations and the plasma levels of fibronectin and fibrin-fibrinogen degradation products in different morphological forms of chronic hepatitis]. / Klinicheskie proiavleniia, soderzhanie fibronektina, produktov degradatsii fibrina i fibrinogena plazmy pri razlichnykh morfologicheskikh formakh khronicheskikh gepatitov.

The paper provides the results of studying the clinical disease manifestations, the plasma content of fibronectin and fibrin and fibrinogen degradation products in patients with chronic hepatitis (CH). It is shown that they are determined not only by the morphological form of CH but also by the structure of inflammatory infiltrates in liver tissue.

[The treatment of atherosclerosis and hypertension using extracorporeal therapy methods]. / Lechenie ateroskleroza i gipertonicheskoi bolezni s primeneniem metodov ékstrakorporal'noi terapii.

Extracorporeal techniques (hemosorption, plasmapheresis, thrombocytoplasmapheresis, quantum hemotherapy) were studied for their impact on the clinical course of a disease and some hemostatic parameters in 370 patients with cardiovascular diseases (coronary heart disease, hypertensive disease, lower extremity at atherosclerosis obliterans). They were found to be effective in managing patients with atherosclerosis and arterial hypertension who are refractory to the conventional drug therapy. When there was a positive clinical action of therapy, the patients with coronary heart disease were demonstrated to show better parameters of lipid metabolism, immunological status and blood aggregation control system. The hypotensive effect of plasmapheresis in patients with arterial hypertension was followed by a decrease in pressor hormone levels and peripheral vasodilatation.

[Pathogenetic and therapeutic significance of the angioprotective systems in patients with coronary arteriosclerosis]. / Patogeneticheskoe i terapevticheskoe znachenie éndogennykh angioprotektornykh sistem u bol'nykh koronarnym aterosklerozom.

The examination of 194 patients with coronary heart disease concurrent with clinical manifestations of angina pectoris established that the development of coronary atherosclerosis was accompanied by suppressed prostacyclin (PGI2) synthesis and increased thromboxane A2 (TxA2) leukotriene (LT) synthesis. The activation of synthesis of the vasoconstrictor and proaggregate TxA2 depended on the severity of clinical signs of angina pectoris. The imbalance of PGI2 to- TxA2 metabolite ratios was associated with dyslipidemias and the extent of coronary atherosclerosis. Bicycle ergometry testing resulted in prostanoid imbalance. The determination of the dynamics of prostanoids was used to check the efficiency of antianginal therapy. The concomitant application of inhibitors of thromboxane synthetase and LT synthesis was recommended for secondary prevention of thrombotic complications in patients with coronary atherosclerosis.

[Fibronectin in acute and chronic hepatitis]. / Fibronectin pri ostrom i khronicheskom gepatite.

[Several aspects of the pathogenesis of chronic circulatory failure in ischemic heart disease: role of atrial natriuretic peptide]. / Nekotorye aspekty patogeneza khronicheskoi nedostatochnosti krovoobrashcheniia pri ishemicheskoi bolezni serdtsa: rol' predserdnogo natriiureticheskogo peptida.

Alpha-atrial natriuretic peptide (ANP) levels, plasma renin activity, and plasma aldosterone levels were measured in 103 patients with coronary heart disease (CHD) having signs of various circulatory failures. The parameters were studied in relation to central hemodynamic values, and their dependence on the stage of chronic circulatory failure. Alpha-ANP was found to be one of the factors of the humoral systems implicated in the pathogenesis of chronic circulatory failure in CHD patients. The plasma level of alpha-ANP was found to be related to the state of the renin-angiotensin-aldosterone system both in healthy subjects and CHD patients.
