Abstract
In preparation for experiments to determine the effects of various orally administered tumor promoters and antipromoters on human skin ornithine decarboxylase (ODC) activity, it was observed that intradermal lidocaine hydrochloride inhibited 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ODC. Topically applied ethyl chloride had variable and unpredictable effects on ODC induction. Adequate local anesthesia can be obtained by using intradermal 1.0% procaine hydrochloride or normal saline; neither of these agents inhibited TPA induction of epidermal ODC activity in incubated human skin punch biopsies.
