RESUMO

We have summarized in this paper main conceptions on structure and function of vascular endothelium with special attention to the role of caveolae both in regulation of function of endothelium itself and transvesicular transport of metabolic substrates. We have also described the role of shear stress in activation of vascular endothelium and putative mechanisms of its action.

RESUMO

Patients with FC II-IV CHD and angina of effort were divided into 3 groups (compensated, subcompensated, and decompensated types) based on vascular reaction to local ischemic load Serum lipid spectrum, parameters of hemostasis and blood flow were evaluated before and after the load. It was shown that each type of vascular reaction had specific predictors. Vasodilation in "compensated" patients was largely due to hydrodynamic changes in the vascular bed. The "subcompensated" type was characterized by reduced sensitivity to this changes "decompensated" type of reactivity was related to metabolic rather than hydrodynamic disorders accounting for paradoxic vasoconstriction in response to ischemic load.

RESUMO

Hemostatic parameters and the diameter of the brachial artery were studied in patients with functional classes II and III angina on exertion before and after an ischemic test. A multivariate statistical analysis was used to determine the significant parameters that distinguish vascular endothelial function in these patients. At the same time it was established that endothelial dysfunction in patients with varying angina pectoris is determined by different predictors of thrombocytic-vascular hemostasis.

RESUMO

We studied effects of neonatal hepatocytes transplantation (NHT) on lipid metabolism and hemostasis in experimental hypercholesterolemia. A positive NHT influence on lipid metabolism, lipid peroxidation and hemostasis was established. The experimental data evidence for preferential influence of intrahepatic NHT on lipid metabolism and hemostasis compared to intravenous NHT.

RESUMO

The study included 30 IHD patients with primary hypercholesterolemia (22 males and 8 females). 18 and 12 patients have received a single daily dose of fluvastatin 20 and 40 mg, respectively, in the evening for 12 weeks. The drug effect was assessed by changes in the clinical status, lipid spectrum, transport-metabolic and absorption-secretory functions of the liver. IHD patients with hypercholesterolemia were found to have dysfunction of the hepatobiliary system. Fluvastatin treatment reduced the level of total cholesterol (Ch), LDLP Ch, triglycerides. HDLP Ch levels remained unchanged. Atherogenic lipoproteins aggregation diminished. Positive changes occurred in hepatic metabolism: bilirubin concentrations lowered, serum albumin went up, absorption-secretory function of hepatocytes normalized, hepatic mono-oxidase system activated. Fluvastatin-related hepatic damage was not reported in the course of 12-month follow-up.

RESUMO

It is demonstrated that negative, "subatmospheric" pressure developing in the heart ventricles during the rapid-filling phase is an evidence of active diastole and inflated capacity of heart chambers. Diastolic activity of the heart increases as a result of insufficient blood inflow to the ventricles coupled with inadequate venous return or narrowed atrioventricular orifice. It is assumed that the heart's diastolic activity is an adaptive-compensatory mechanism adequately stabilizing circulation under changing hemodynamic conditions.
