[In vivo study of microcirculatory pathways by the contact microscopy technic]

Microcirculatory bed in some organs of a normal brown frog Rana temporaria has been studied at vital observation by means of the luminescent photomicroscope LIUMAM K-1. Elements of the microcirculatory bed have been determined according to the direction of blood stream and the diameter of its separate links. Certain peculiar features of the blood stream have been studied in the dark field in the organs such as: the skin, the tongue, the gastric wall, the intestinal wall, the lungs and others. The range of morpho-functional lability in the microvessels and structural organization of the bed in question depend on the structure of certain organs. A close connection between the microvascular wall and melanocytes has been revealed.
