Omo- and contralateral changes in cholinergic enzymes in muscles following immobilization, in the rabbit

Changes in ChAc and AChE activity were observed in the caput longum of the triceps of both forelimbs of 45-day-old rabbits when the left antebrachium was immobilized in total extension on the brachium for periods of up to 60 days. Enzyme determinations on the proximal, ventral and distal portions showed a correlation between quantitative changes in AChE activity, and the reappearance of its terminal activity demonstrated histochemically by other workers with the same experimental model.
