[Comparative analysis of the regenerative activity o the muscular and neural tissues after trauma and after transplantation of minced muscle].
Regenerative processes in the body muscle of fish Variocorhinus capoeta sevangi were studied both after the excision of a portion of three muscle segments and following autografting minced muscle into the defect formed. Muscle trauma resulted in a damage field, including the defect and the adjacent degeneration zone. The inflammation, necrotic mass resolution and regeneration of the nerve and muscle tissues were lengthy. Formation of myogenic elements started during the 3rd week only. Individual regenerating nerve fibers in the damage zone appeared 2 months later. Filling the defect with minced muscle accelerated the regeneration. The grafted muscle fiber fragments were not only involved in the regenerative process, but also stimulated the plastic activity of the muscle and nerve tissues of the grafted bed.
