[METABOLIC CHANGES OF SKELETAL MUSCLES IN TRAUMATIC INJURY OF PERIPHERAL NERVE AND AUTOPLASTY IN EXPERIMENT].

ABSTRACT

The changes in metabolism of the amine acids, enzymes, electrolytes, fat acids (FA) in skeletal muscles of anterior and posterior extremities of rats in significant defects of peripheral nerve and its autoplasty were studied in experimental investigation. Metabolic changes in skeletal muscles are accompanied by significant intensity of proteolysis, lowering of the enzymes activity, energetic metabolism and in a less extent of the electrolytes balance and the FA metabolism. After autoplasty of big defects in the traumatized nerve the proteins' synthesis and restoration of activity of lactate dehydrogenase and creatine phosphokinase constitute the markers of muscular tissue restoration. Surgical restoration of the nerve is accompanied by a protein synthesis activation in muscles, but normalization of the enzyme systems indices, the lipids metabolism and the electrolytes balance was not observed. Metabolic dysbalance needs a certain pharmacological correction and prevention of a progress of pathological process in skeletal muscles.
