Abstract

Purpose: The successful wound healing means the scarless wound with adequate strength. It has been shown in vivo and in vitro that steroid retard the collagen synthesis. We studied the effect of steroid on the wound breaking strength in rats. Methods: 40 Sprague - Dawley rats were evenly assigned to two groups. One group was served as control, the other group was experimental. We made dorsal midline incision and closed the wound. In the experimental group, we medicated methylprednisolone (0.15 mg/g/day) for 1 week. Then, we compared the differences of the breaking strength and microscopic histology between control and experimental group at 2, 4, 6 and 8 week. Results: Up to 4 week, the breaking strength of the experimental group was markedly decreased than that of control group, while at 6 week the strength of experimental group attained to that of control group nearly. In histologic findings, control group demonstrated dense organization of collagen to experimental group at 4th week. Conclusion: In this experiment, steroid significantly inhibited the strength gain in wound at early period of the wound healing process. When using steroid after the surgery or the wound formation, it is desirable to administrate carefully and need thorough wound management to prevent delayed wound healing.
