Abstract
Changes in oxidative enzyme and acid phosphatase activity, glycogen, ribonucleic acid (RNA), and lipid were demonstrated by histochemical technics in gingival epithelium of squirrel monkeys after experimental arteriolar occlusion. After 24 hours, glycogen and lipid content increased, and all enzyme activity, except lactic dehydrogenase, was depressed. By 72 hours, enzyme activity associated with the hexose monophosphate shunt was elevated.
