Using microdensitometry, the recovery courses of glycogen concentration and lactic dehydrogenase (LDH) reactivity were monitored following a standard period of epithelial anoxia. Although the reactivity imbalance of LDH between the superficial and basal cell layers was restored, as was the sagittal thickness of the epithelium, by about six hours, recovery of epithelial glycogen to preanoxic levels required about twice that time.
