Hyper-induction of skin ornithine decarboxylase activity in psoriatic patients.
Ornithine decarboxylase activity was measured in skin from 14 normal and 24 psoriatic subjects (with stable plaque type psoriasis vulgaris) using punch biopsies carried out immediately (0 h) and 6 h after stimulation by cellotape stripping. At 0 h, no significant difference was found between normal and involved or uninvolved psoriatic skin, but a significant increase was measured 6 h after tape stripping. This increase was significantly greater in uninvolved and involved psoriatic skin compared with normal skin. Preliminary results indicated that these changes were localized in the epidermis.
