Fig 3. Comparison of wound sizes on different days in animals not exercised and administered varying doses of PCB (n = 4–10).

C, E and F: The mean wound size is less on Day 2 through Day 6 in PCB 1000 treated animals as compared to PCB 0, PCB 100 and PCB 500 administered mice, though no significant differences or trends were observed. A, B, and D: No significant differences or trends and no difference in means were observed when the other doses of PCB were compared.
