[A functional-morphologic analysis of reactive changes in nerve fibers during development of collateral circulation in nerves].
After stopping the blood circulation along the femoral artery the collateral blood circulation is developing unevenly in different nerves. It depends on the architectonics of blood vessels of the zone. In time the intravenous anastomosis in the distal part of the ischiatic nerve sharply increases. It is pulsing and compressing the nerve bundles and may have a negative influence on nerve fibres. Reactive morphological changes of the axis cylinder, myelin incisions and Ranvier's constrictions are found in such a nerve. The analysis has shown that the changes noted have a character of local non-specific process accompanying physiological manifestations of parabiosis.
