Porcine acellular dermal
collagen (PDC), which is a
biological material derived from processing porcine dermis, has already been used for urologic, gynecologic,
plastic, and general surgery procedures up to now. The aim of this study is to investigate the effectiveness of PDC on wound healing as a dermal substitute in the rat model. Twenty Wistar albino rats were divided into two groups. Standard full-thickness skin defects were created on the back of the rats. In the control group (Group 1), the dressings moisturized with saline were changed daily. In the study group (Group 2), porcine dermal
collagen was implanted onto each
wound and fixed with 4-0
polypropylene sutures. Contraction percentages of
wound areas were calculated on the third, seventh, tenth, and fourteenth days by using the planimetric program. On fourteenth day, the
wound areas were excised for histopathological examination, inflammatory scoring, and evaluation of
collagen deposition. The study group was superior to the control group in terms of inflammatory scoring, type I/
type III collagen ratio, and
wound contraction rates. Porcine dermal
collagen may be used effectively and safely on full-thickness
wounds as a current dermal substitute.
