[Effect of hypodynamia on the hemomicrocirculatory bed of the triceps muscle and brachial fascia in the rat].
By means of amputation of the forearm (the place of the brachial musculus attachment is kept intact) in 30 male rats certain conditions are produced for decreasing force activity in the m. triceps brachii. Anatomical changes in structure and in distribution of links of the hemomicrocirculatory bed (HMCB) are followed in the medial head of the muscle and in the fascia covering it. Time of observations - 1-60 days. The sections of the muscles and some parts of the fascia are impregnated with silver nitrate solution. The greatest changes are observed to occur in the capillary-venular links of the HMCB during the interval of 1.14-4.5 days and are manifested as initial congestion of venous blood in these links. Later (4.5-15.3 and further 60 days) together with stable dilatation of all venous components of the blood bed certain qualitative changes take place in the arteriolar links of the HMCB.
