[Changes in the microcirculation of the pericardium of the dog during adaptation to static muscular loads]

The data obtained revealed an increase of physiological working ability, economizing of a number of functions on the systemic level as well as morphological parameters of the vascular microregion in the course of training--adaptation to muscular loads in dogs. Apart from that, an increasing permeability for water and protein was maintained due to a beneficial readjustment of the microregion--module communications as well as to augmentation of all the parameters of the metabolic link. Desadaptation led to decreasing physiological working ability and inadequate increase in the circulation and respiration on the level of systemic parameters. On the other hand, the transcapillary exchange of water and protein was significantly decreased with a respective morphological reduction of the pericardium capillaries' metabolic surface.
