The review was focused on the data demonstrating that flow induced arterial dilation depends not only on intact endothelium but on intact endothelial glycocalyx, as well. These data demonstrate that filaments of the endothelial glycocalyx serve as me

In the review we analyze a counteraction of two mechanogenic mechanisms that control vascular hydraulic resistance: 1) myogenic response, and 2) ability of vascular endothelium to change the smooth muscle tone in responce to changes of wall shear str

In experiments on cultured endothelial cells of human umbilical vein, we found that incubation of these cells during 24 hours with malondiaidehyde (cone. 200 microM) led to over two-fold increase in the cell stiffness. These data suggest that manifol

The effect of control of arterial diameter by the shear stress at the endothelium on noradrenaline-induced constriction of femoral vascular bed was investigated in anaesthetised cats. We compared noradrenaline-induced responses during the perfusion o

In anaesthetised cats, the arterial input impedance in combination with seven-element lumped-parameter model was used to estimate the resistance change in arteries of different caliber. The results show that the method gives reasonable estimations of

Vascular input impedance can be used as an effective tool in estimating hydraulic parameters of arterial bed. These parameters may be interpreted as hydraulic resistance, elastance and inertance of particular sites of the arterial system. There is no

Treatment of the femoral artery luminal surface with glutaraldehyde dimere or dithiosuccinimidyl propionate reduced or eliminated flow-induced dilation, the responses to acetylcholine and the ATP being preserved. The findings suggest that the endothe

In 19 anaesthetised cats, the response of vascular bed to increasing perfusion pressure at a constant blood flow perfusion consisted of two phases: a myogenic constriction and a subsequent arterial dilatation. The latter depended on ability of the en

A decrease in the blood viscosity due to hemoconcentration, caused arterial dilatation. These viscosity-induced responses depended on intact endothelium. The dilatory responses caused by equal increments in flow rate, increased in systemic hemoconcen
