Effects of denervation and nerve crushing on chicken muscle.
When compared with the standard free muscle grafts, predenervated and nerve crushed chick gastrocnemius muscle grafts followed an identical and ordered sequence of tissue degeneration-regeneration. Atrophy of the fibres during ischaemic degeneration was accompanied by loss of weight, noncollagenous proteins and increment in lytic enzymes (acid and alkaline phosphatase), glucose 6-phosphatase, glycogen and succinate dehydrogenase. Regeneration was more rapid in standard free muscle grafts. Trophic insults to muscle via denervation and nerve crushing prior to transplantation did not influence graft renewal when compared with standard free muscle grafts though relatively increased recovery was shown by predenervated muscle grafts.
