AMP deaminase histoenzymatic staining in rat intrafusal muscle fibers and other skeletal muscle tissues.

AMP deaminase activity is detected by histoenzymological technique in intrafusal skeletal muscle fibers, at the level of the Schwann sheath of nerve fibers, in the intima, and in the media of arteries and in the capillary walls. The localization of high AMP deaminase activity appears to correspond to the localization of high ATPase and high glycolytic activity.
