Abstract: The exposure of benzyl isothiocyanate (BITC) to mouse skin resulted in the attenuation of 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced oxidative damage through not only inhibition of the NADPH oxidase system but also leukocyte clearance at inflamed region. In spite of little ability to affect TPA-induced edema formation, pretreatments of mouse skin with BITC before the first or second TPA treatment significantly decrease the H_2O_2 level. A histological study also demonstrated that BITC enhanced the terminal deoxynucleotidyl transferase-dUTP nick end labeling (TUNEL)-positive index in mouse skin, suggesting that BITC might accelerate the disappearance of infiltrated leukocytes. Thus, these gathered data further supported that BITC has a potential as an anti-inflammatory agent.
