Tsarev A. Changes of haemomicrocirculation of the muscle fibre in the limbs of rats with damage to the femoral and sciatic nerves

Work is devoted to the problem of regularity of the developmental features The aim of this study was to determine the changes occurring in the limbs of rats with damage to the femoral and sciatic nerves. Damage of femoral and sciatic nerves caused by cross clamping of back extremities at level of the top third of hip by means of a haemostatic clamp throughout 1-4 hours, and also by a section of this nerve. As the control back extremities contrlateralis the parties served. After transactions of the sciatic nerve changes in the limbs are a number of successive stages. We investigated the early changes in these conditions. In the first hour with transaction of the sciatic nerve, a decrease of the specific mass of the muscle fibre and its reduction by the fourth hour of the experiment by cutting the femoral nerve changes in the muscles of the front panel there are similar changes in the back of the thigh muscles and occur in the same sequence. When the femoral nerve transaction diameter of the arterioles to the fourth hour of the experiment is increased 1,46 times and 1,8 times in venules. The diameter of the capillaries does not change.
