    Abstract:
    Background Diabetic wound are the major problem of society because of its delay healing of wound in hyperglycemia patient. The target of this study need to know the gallic acid compelling synergistically wound healing in diabetic animals as it is available in fruit extract or is more effective in given pure form in diabetic animals. Methods The wound healing effects of fruit extract Terminalia bellerica Roxb. and gallic acid were evaluated in experimentally induced hyperglycemic animals. In this investigation, excision and dead space wound models were used. The contraction wound %, re-epithelialization days, area of scar, histopathological examination of tissue, hydroxyproline level and weight of tissue granuloma were evaluated in this study. Results Terminalia bellerica fruit extract (400 mg/Kg) and gallic acid (200 mg/Kg) have been ingested by orally in streptozotocin induced diabetic rats. They were founded significantly (p<0.05) improved percentage wound contraction and decreased the size of scar area and days of re-epithelialization in excision wound model. Also, they were improved the level of hydroxyproline level in diabetic rats as compared to diabetic control group in dead space wound model. Standard drug vitamin C was also founded significantly improved wound healing activity in rats. These results suggested that treated groups accelerated wound healing activity in diabetic rat. Conclusions The observations and results obtained in the present study indicated the wound healing efficacy of fruit ethanolic extract and gallic acid in diabetic animals. Yet, the wound healing effect was increasingly reported with gallic acid.
