摘要

(1) Activity of superoxide dismutase (CuZn- and Mn-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), glutathione S-transferase (GST) and thioredoxin reductase (TR), and the amount of glutathione (GSH) were assayed in the skin of control (22 +/- 1degreesC), cold-adapted rats (45 days, 5 +/- 1degreesC), and cold-adapted rats brought back to room temperature after 1, 3, 7 and 15 days.
