Abstract:
Objective: To investigate the efficacy of oral, external and oral plus external application of recipes for promoting granulation on chronic skin ulcers in rats. Methods: Sixty SD male rats were randomly divided into normal group, untreated group, oral group, external group and combined group (n=12). Chronic skin ulcer was induced by hydrocortisone injection and back skin incision. After oral administration of Fuzheng Huyu Recipe or (and) external application of Baiyu ointment, the compound traditional Chinese medicines for wound healing, healing time and healing rate of the ulcers were observed. Results: The healing rate was lower and the healing time was longer in the untreated group than in the normal group (P<0.01). The healing rates of the oral group and the combined group were higher than those of the untreated group at all observation points (P<0.05), and the healing rate of the external group was higher on the 3rd and 14th day after model establishment (P<0.05). On the 7th and 10th day after model establishment, the healing rates of the oral group and the combined group were higher than those of the external group (P<0.05), and the healing time of the combined group was shorter than that of the oral group and external group (P<0.05). Conclusion: Both orally and externally administered wound healing recipes can promote the restoration of chronic refractory ulcers; the effect of combined administration is superior to single administration. Oral, external and combined application can all improve the wound healing in inflammatory phase. Oral and combined application can obviously improve the wound healing in granulation phase and epithelial phase.
