Adenyl cyclase activity was constantly present in the plasma membrane, and granular precipitates suggesting activity in the mitochondria were noted in some fibers after reaction stimulation with activators. In the muscle degenerated by plasmocid, the localization of adenyl cyclase activity did not change, but in general, the intensity of the enzyme activity decreased slightly in comparison to that of the normal muscle. NaF or epinephrine stimulation of injured muscle resulted in a less marked increase of reaction than that of the normal muscle. This was considered to be a possible indication of changes in the plasma and mitochondria membranes in the acute phase of plasmocid injury of skeletal muscles.
