Abstract:

OBJECTIVE: To assess the wound healing potential ofon cutaneous wounds in diabetic rats.

METHOD: Full-thickness excisional wounds were made on the back of male, Sprague-Dawley rats with diabetes. The rats were randomly allocated into four treatment groups: 1ml basal cream; tetracycline (3%);10% for 14 days; and a control group. At days seven, 14 and 21 post-injury, five animals of each group were euthanised, and wounds were assessed through gross, histopathological and oxidant/antioxidant evaluations. Additionally, the dry matter and hydroxyproline contents of the skin samples were measured.

RESULTS: A total of 60 rats were used in the study. A significant decrease in the wound size was observed in treated animals withcompared with other groups during the experiment. Additionally, treatment withdecreased the number of lymphocytes and improved the number of fibroblasts at the earlier stages and increased a number of fibrocytes at the later stages of wound healing. Other parameters such as re-epithelialisation, tissue alignment, greater maturity of collagen fibres and large capillary-sized blood vessels revealed significant changes when compared with the control.significantly reverted oxidative changes of total antioxidant capacity, malondialdehyde and glutathione peroxidase induced by diabetic wounds (p<0.05). Furthermore, it significantly increased the dry matter and hydroxyproline contents at various stages of wound healing (p<0.05).

CONCLUSION: The present study showed that application ofextract promotes wound healing activity in diabetic rats. The wound-healing property ofcan be attributed to the phytoconstituents present in the plant.
