The metallothionein (MT) content in hairless mouse skin was determined after topical application of various glucocorticoids or zinc oxide (ZnO). Dexamethasone (1%) in a cream base or zinc paste (20% zinc oxide) were applied twice daily, at a dose of 0.5 g, to the dorsal surface of the mouse. These experiments were conducted for 7 days. The MT content of the skin increased in a time-dependent manner after dexamethasone application with maximal values (7.1 +/- 0.29 pmol MT/mg wet weight) seen after 5 days, whereas zinc paste caused only slight increases after 3 days of treatment. The effect of hydrocortisone and triamcinolone-acetonide on the MT content of the skin was also studied. The physiological significance of these results is briefly discussed.
