Objective: To explore the mechanism of Shengji Huayu Recipe (SJHYR) and its 3 disassembled formulae in accelerating wound healing toward skin restoration.
Methods: Using in vitro cultured fibroblasts from granulation tissue of wound and compared with the normal skin fibroblast of suckling rat, who were treated separately by drug serum containing high and low dose SJHYR and its disassembled prescriptions (Shengji formula and Huayu formula). The type I and III collagen contents in the fibroblasts were determined with immunocytochemical ABC method.
Results: Shengji formula could increase the levels of type I and III collagens in fibroblasts, which was significantly higher than those in model cells and control (P < 0.01). Huayu formula lowered them to the levels below those in model cells (P < 0.01), while in comparing the levels in the cells treated by high or low dose SJHYR with those in control, no significant difference was shown(P > 0.05).
Conclusion: SJHYR might accelerate wound healing toward skin restoration through regulating the ratio of collagen type I and III, to adjust their metabolism.
