Wound healing potentials of Thevetia peruviana: Antioxidants and inflammatory markers criteria

Wound healing potentials of Thevetia peruviana: Antioxidants and inflammatory markers criteria
Thevetia peruviana is a medicinal plant used in the treatment of external wounds, infected area, ring worms, tumours etc. in traditional system of medicine. The aim of the study was to evaluate the wound healing potentials of T. peruviana leaves hexane (LH) and fruit rind (FW) water extracts and to prove the folkloric claims. The antimicrobial, antioxidant and anti-inflammatory potentials could be important strategies in defining potent wound healing drug. Based on these approaches the current study was designed using incision, excision and dead space wound models with the biochemical, antioxidant enzymes and inflammatory marker analysis. The fruit rind water extract showed highest WBS of 1133 ± 111.4 g. The extracts in excision model retrieved the excised wound i.e. complete healing of wound at day 14. The hydroxyproline content of FW and LH treated dry granuloma tissue was increased to 65.73 ± 3.2 mg/g and 53.66 ± 0.38 mg/g, accompanied by elevations of hexosamine and hexauronic acid with upregulation of GSH, catalase, SOD, peroxidase and the down regulation of the inflammatory marker (NO) and oxidative stress marker (LPO) in wet granulation tissue was documented. Conclusively, both the extracts showed enhanced WBS, rate of wound contraction, skin collagen tissue development, and early epithelisation. Therapeutic wound healing effect was further proven by reduced free radicals and inflammatory makers associated with enhanced antioxidants and connective tissue with histological evidence of more collagen formation. The present research could establish T. peruviana as potential source of effective wound healing drugs.
