[Both fumigation and heating of moxibustion promote wound healing and tissue repair in rats with full-thickness skin incision].
摘要
OBJECTIVE: To investigate the effect of moxibustion on wound healing, new capillaries and tissue repair in rats with full thickness skin excision. METHODS: SD rats were randomly divided into control, moxa-fumigating and moxa-heating groups, with 24 rats in each group. The full-thickness skin excision injury model was replicated according to Balaji's and colleague's methods. Rats in the moxa-fumigating group received fumigation of moxa-smog at the wound surface (25 min/time) immediately after modeling through a smoke-heat separation device, and those of the moxa-heating group received conventional thermal stimulation of the ignited moxa over the wound (25 min/time) without moxa smog, once a day for 10 consecutive days. The wound color, pus, carrion, granulation, and healing status of the rats were observed. H.E. staining and Masson staining were used to observe the local tissues and collagen fibers of the wound on the 3rd and 7th days. Newly born capillaries at the wound surface were observed on the 10th day. RESULTS: <0.05). CONCLUSION: Both fumigation and heating of moxibustion can promote wound healing in rats with full-thickness skin excision injury，which may be related to their effects in controlling the inflammatory response and promoting the production of collagen fibers, granulation tissue and capillaries.
