[Methods of intravital study of the microcirculatory bed and assessment of vital dye transport in the pericardium].
The method of vital microscopy was used to obtain new data on the features of blood microcirculation in different links of the vascular bed in the pericardium. The work of dynamic structures of microcirculation pathways controlling processes of redistribution of blood streams is shown such as arteriolar anastomoses, zones of branching of resistance microvessels, the pathways of magistralization of the capillary blood stream, venular anastomoses and microvalves. By means of calorimetric study of the serous fluid obtained from the pericardium cavity, after a preliminary intravenous injection of the vital dye a quantitative evaluation of the transcapillary transport of the dye was made under conditions of a normal and altered permiability.
