title: [Comparative morphometry of vessels of the microcirculatory bed of the cat pericardium in impregnated preparations and during in vivo microscopy].
abstract: In impregnated (with silver nitrate) preparations of the cat pericardium and in photonegative pericardial microvessels photographed in vital experiments, diameters of the main vascular groups in the microcirculatory bed (arterioles, precapillaries, capillaries, postcapillaries and venules) were comparatively estimated. When impregnated, the vascular diameter decreases; the degree of the changes is not equal and depends on the wall structure. Therefore, when studying impregnated preparations, it is necessary to introduce the correction coefficients in order to make the data obtained comparable with the vital ones.
