摘要
Objective: To explore the molecular biological mechanism of Arnebia root oil promoting wound surface healing by observing histological change and bFGF expression in wound surface tissue as well as wound surface healing rate. Methods: Raw surface in patients were randomly divided into 2 groups. Experimental group was treated by Arnebia root oil and control group was treated by petrolatum gauze, then the tissular structure of raw surface was observed by histology, histochemistry. electron microscope and raw surface healing rates was compared either. bFGF expression in wound surface tissue was also evaluated by Western-blot. Results: Raw surface healing rate of experimental group and control group had obvious difference(P<0. 05). Raw surface of experimental group had more fibroblast, collagen and blood capillary. bFGF was expressed in both groups, and the level of bFGF expression in experimental group was higher than that in control group in every period. There were significant differences between 2 groups in gray-density value ( P<0. 05). Being as an internal control, no significant change was found for β-actin expression, although it occured in various phases. Conclusion: Arnebia root oil plays an important regulative role in the course of healing of wound and it can promote skin raw surface repair and accelerate wound surface healing, which are caused by enhancing bFGF in the wound tissue.
