[Microcirculatory bed and the structure of the compact substance of the cat tibial diaphysis normally and after multiple exposure to G loads].

Blood bed and structure of the compact substance of the cat tibial diaphysis have been studied at normal conditions and after repeated effect of gravitational overloadings. Hypergravitation produced a noticeable rearrangement in the microcirculatory bed and in histoarchitectonics of the bone compact substance. The date obtained demonstrate that the changes produced depend on the number of parameters participating in the gravitational effect and on the position of the animal in the container, as well as on the time when the animal falls ill after the experiment.
