AbstractThe present study aims to evaluate for the first time the wound healing and in vivo anti-inflammatory effects of glycosaminoglycans from skins of smooth hound (SHSG) and grey triggerfish (GTSG). Thermal analysis of GTSG and SHSG was evaluated using differential scanning calorimetry (DSC). The rheologie properties and water absorption capacity of two gels prepared from SHSG and GTSG were also studied. The application of GTSG and SHSG based gels on dermal full-thickness excision wounds in a mouse model, enhanced significantly wound healing activity and a total closure was achieved after eleven days of wound induction for SHSG. Further, histological examination of biopsies showed advanced tissue regeneration, characterized by the presence of well-organized stratum of both derma and epidermis. The anti-inflammatory evaluation of GTSG and SHSG in mice showed a significant inhibition of edema paw, after 5 h of carrageenan injection. The edema inhibition was 91.6% and 90% for SHSG and GTSG, respectively at the dose of 50 mg/kg. Furthermore, the histological evaluation and the superoxide dismutase, catalase and malondialdehyde level in muscle tissue were investigated. In summary, this work demonstrates that both GTSG and SHSG could be promising drugs with good wound healing and anti-inflammatory effects in animal model.
