Abstract :
Background & aim: Wound healing is a complex programmed sequence of cellular and molecular processes. The objective of the present study was to evaluate the ability of earthworm’s hydro-alcoholic body extract (EBE) to heal the experimental skin wound in goldfish (Carassius auratus gibelio).Materials and Methods: Fish (independent triplicate, 14/group), for 14 days, were divided into 5 groups 1) negative control (Unwounded); 2) pseudo-control (sham): wound treated with EBE carrier (mixture of castor oil and white vaseline); 3) Positive control: wound treated with sodium phenytoin 1%; 4) 1 mg/gr EBE-treated wound, 5) 10 mg/gr EBE-treated wound. In this study, macroscopic and microscopic evaluations and collagen turnover (Hydroxyproline content) in the skin, along with determination of lysozyme activity in blood sera were carried out. Results: In fish in group 4 (1 mg/gr EBE-treated wound), an increase in the epithelium diameter, good presence and appropriate synthesis of collagen with and low edema in dermis; increased hydroxyproline content; and elevated blood lysozyme activity were observed comparing to other groups.Conclusion: Our results revealed that application of 1 mg/gr EBE might be as an effective medicinal material in the process of animal wound healing particularly in aquatics.
