Backgrounds & Hypericum is a traditional medicinal plant that used for the topical treatment of superficial wounds, burns and dermatitis.the aim of this study was to evaluate the effect of Hypericum perforatum extract and1 % silver sulfadiazine on a second degree burn wound healing in the male rat. This experimental study was performed on 30 adult male Wistar rats weighing 50 ± 200 gr. To make the second degree burns wound at area of 2 square centimeters with boiling water, animals were anesthetized using sodium thiopental. The animals then divided into three equal groups randomly. Control group was washed with sailine every day. The second and the third groups were treated with 1% silver sulfadiazine ointment and Hypericum perforatum extract respectively. After thirty-five days of treatment, mice were anesthetized and tissue samples were taken for processing and staining with hematoxylin and eosin and examined under light microscope. Data were analyzed using one-way ANOVA. Average surface burns,thickness of the epidermis and malondialdehyde levels in HP treatment compared with 1% silver sulfadiazine was close to normal control but no significant differences was found between Hypericum perforatum extract and silver sulfadiazine at duration of treatment (p> 0.05). Although there was no statistically significant difference, but the restorative effects of HP -treated group compared with the other groups showed better result.
