Glutathione in human epidermal tumors. Basal and squamous cell epithelioma, verruca seborrhoeica.

Methods for the determination of glutathione in small epidermal and tumor fragments are compared. The best results were obtained by an enzymatic cycling technique. The total glutathione concentrations in basal cell epithelioma, squamous cell epithelioma, and verruca seborrhoeica were 2.08, 1.81, and 1.87 mg/g dry weight, respectively. In normal epidermis adjacent to the basal cell epitheliomas the concentration was 1.27 mg/g dry weight.
