[Homo- and contralateral changes in muscle cholinergic enzymes 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 determination on the proximal, ventral and distal portions showed a correlation between quantitative changes in AChE activity, and reappearance of its terminal activity demonstrated histochemically by other workers with the same experimental model.
