Histological effects of the smoke of Verbascum speciocum leaves on the healing of rats wounds

The aim of this study was to assess the effect of the smoke of Verbascum speciocum leaves grown in ''Bouein Zahra'' region، on the healing of skin lesions in Wistar rats. In this study in vivo conditions، 36 adult male Wistar rats were randomly divided into 3 groups. The operation day was considered as day zero and the procedure took 10 days. After the end of the treatment، i. e.، on the 14th day، rats were killed by choloroform and samples were collected for histological analysis Masson trichrome and Vangason staining for collogen and hydroxyprolline amino acid OD assessment was applied. Studies in experimental groups exposed to the smoke of the leaves revealed that there was no increase in epidermis thickness، hair follicles diameter، skin، nor in the number and diameter of blood vessels as compared with control and sham groups. However، the amount of hair follicles was decreased. There was an increase in collogen diameter but this increase was not significant. But a significant increase was observed in OD of hydroxyl proline amino acid assessment (p<0. 001) in experimental groups compared with sham and control groups. The results indicated that the use of smoke of V. speciocum leaves on the skin lesion had absolutely no increase on the wound healing ratios and its closure; it maximally could had very little effect on the proliferation as one step in the repair process، which needs further investigation.
