Description

This study was performed to establish a circular excisional wound model treated with hydrocortisone (HC-P) and to estimate the following parameters in this model: wound area, hydroxyproline (Hyp) content, histological characteristics and microscopical measurements of histological sections. HC-P inhibited the reduction of wound area, the increase in Hyp content and proliferation of granulation tissue in a dose-dependent manner. The application of ZnO ointment significantly accelerated the reduction of wound area and the increased Hyp content in rats treated with HC-P. From these results, we concluded that this experimental model is useful for the objective evaluation of the efficacy of drugs that promote wound healing.
