Abstract
1. Cytochrome oxidase activity of epidermis of mice on 4th day of hair growth cycle was appreciably higher than of epidermis of 12th and 22nd days of cycle. 2. Hair follicle preparations from very young mice had much greater cytochrome oxidase activity than did epidermis of 12th and 22nd days of cycle. 2. Hair follicle preparations from very young mice had much greater cytochrome oxidase activity than did epidermis regardless of stage of hair growth. 3. DPNH-cytochrome c reductase activity of epidermis of 12th day of hair growth cycle was significantly less than that of epidermis removed on 4th and 22nd days of cycle. 4. Activity of cytochrome oxidase appears associated to some extent with mitotic activity of tissues examined.Keywords
