Abstract

This study was undertaken to evaluate the wound healing properties of Tragopogon porrifolius (TP) on cutaneous wounds in rat. A full-thickness cutaneous defect (2×2cm) was induced on the back of 60 Sprague-Dawley rats. The animals were randomly divided into four equal groups, treated with 1ml basal cream (placebo group), 1ml tetracycline (3%), 1ml TP 10% and untreated (control). Five animals of each group were euthanized at each of 7, 14 and 21 days post-injury (DPI) and wounds were evaluated through histopathological analyses. Treated animals with TP showed a significant reduction in the wound surface area at 14 and 21 DPI compared to other groups. In addition, treatment with TP reduced the number of lymphocytes and enhanced the number of fibroblasts at the earlier stages of wound healing and increased number of fibrocytes at the later stages of wound healing. TP significantly improved alignment of the healing tissue, re-epithelilization and epithelial formation, enhanced maturity of the collagen fibres and fibroblasts and large capillary-sized blood vessels. The present study demonstrated that the methanolic extract of T. porrifolius promoted wound healing activity in animal as a preclinical study. These results showed that application of TP extract on wounds induces significant wound contraction and accelerated healing and it may be suggested for treating various types of wounds in animal and human beings.
