Abstract: | In the present study effect of asiaticoside, on healing of skin wounds in Cirrhinus mrigala is reported. Skin wound, approx. 2 mm in diameter was excised using sterile disposable biopsy punch. Immediately after infliction of the wound, epidermis from wound edge starts migrating as thin sheet toward wound gap. Fronts of migrating epidermis gradually advance, and results in complete epithelialization of wound. Experiments were conducted for 30 days and fishes were divided into control, sham, vehicle control and asiaticoside treated groups. Immunohistochemical localization of proliferating cell nuclear antigen positive cells indicating cellular proliferation and caspase 3 positive cells reflecting apoptosis was carried out and their density at different post wound intervals in each fish group was analyzed. Significant increase in cellular proliferation as well as decrease in apoptosis in both epidermis and dermis in fish treated with asiaticoside compared to sham and vehicle control fish is observed at different intervals of wound repair. This suggests that in treated group healing of skin wounds in fish is enhanced than in sham and vehicle control groups. Asiaticoside treatment in healing of skin wounds would greatly be beneficial to fish farmers as it could protect fish from invasion of pathogens and check fish mortality. |
