CHARACTERISATION OF RESORBABLE AND NON- RESORBABLE SUTURES COATED WITH Punica granatum SEED EXTRACT: AN in vitro PILOT STUDY.

BACKGROUND: In order to achieve uneventful and rapid healing of the tissues, a suture material should be biocompatible, easy to handle, sterile, and have good and uniform tensile strength. Hence, in the present study, characterization of the suture materials was done through a novel green chemistry approach using Punica granatum seed extract.

MATERIALS AND METHODS: Ethanolic extract of P. granatum seed was prepared by dissolving 25 g of P. granatum seed powder with 100 mL of ethanol. The obtained extract was coated in silk and Vicryl suture material and was tested for its surface morphology (SEM), tensile strength, anti-microbial activity, biocompatibility, and wound healing potential.

RESULTS: Silk and Vicryl sutures coated with P. granatum seed extract showed the uniform coating and deposition of extract with sustaining integrity. Vicryl suture coated with the extract had good tensile strength and antimicrobial activity. The in vitro scratch assay and biocompatibility test showed that the P. granatum seed extract had excellent wound healing potential and can be used without any effect on the viability of the normal cells.

CONCLUSION: Within the limitations of the study it can be concluded that P. granatum seed extract coated Vicryl sutures had good tensile strength and anti-microbial activity. P. granatum seed extract also showed excellent biocompatibility and wound healing potential.
