The effects on epidermal DNA synthesis of topically applied cycloheximide

Abstract
An animal model [female A2hr mice] for investigating topically applied epidermal cytotoxic drugs to determine optimum therapeutic doses and schedules is described. It is used here to examine the effect of cycloheximide on epidermal DNA synthesis, as measured by 3H-thymidine incorporation in vivo, in terms of dose/response [for cutaneous malignancy and psoriasis] and activity/time profiles and potential systemic toxicity.
