[A radionuclide method of quantitative evaluation of the venous blood flow in the legs].

The determination of mean time of transport of an agent in radionuclide phlebography is technically a simple and highly effective method of diagnosis of diseases of the lower limb veins that can be effectively used in all hospitals, fitted out with gamma-cameras with a computerized system.

[Electron microscopic study of intestinal auto-, allo- and xenotransplants in the 1st hours following extracorporeal perfusion].

Mucous membrane ultrastructure was studied after extracorporeal perfusion of the small intestine under auto- (12 experiments), allo- (10 experiments) and xenotransplantations (4 experiments). In all mucosal structures the lesions are demonstrated to depend on nonspecific factors on the one hand, and on genetically foreigh tissue, on the other hand. In every experimental group, the earliest changes occur in microcirculatory bed.
