Combined Effects of Retinoic Acid and Hydro-Alcoholic Extract of <i>Rosa Damascena Mill </i>on Wound in Diabetic Rats

Abstract

Retinoic acid and Rosa damascena are compounds that have considerable effects in the cellular proliferation and synthesis of extracellular matrix. The present study was designed to assess the combined effects of retinoic acid and Rosa damascena mill on wound in diabetic rats. Seventy-two rats were used in this study. Diabetes was induced by a single intraperitoneal injection of streptozotocin (60 mg. Kg-1). Then, a full thickness wound was created on dorsal surface of all animals. After that, rats were divided, into three groups; control (normal saline), positive control (Phenytoin), and case (combined of 0.1% Tretinoein lotion and hydro-alcoholic extract of Rosa damascena mill). Afterward, wounds were evaluated macroscopically and microscopically on days 5, 10 and 15. Macroscopic and microscopic evaluations showed a significant improvement (p
