Impact of Morphine Dependency on Secondary Intention Wound Healing in Rat
Abstract
Wound healing has always been among important and crucial subjects in medicine. Morphine dependency has also been a social and health problem in the Middle East. This study was aimed to investigate the effects of morphine dependency on pro-inflammatory and fibroblast cell recruitment, as well as re-epithelialization and the revascularization processes involved in secondary intention wound healing in rats. A full-thickness wound (2×2 cm in diameters) was created on the dorsum of two groups of rats, a control group and a second group consisted of morphine dependent rats. During the first 14 days of post wounding the wound was excised consecutively at priorly planned days with peripheral margins of normal skin. The specimens were evaluated by two pathologists, who were blind to the study design, and the cellular population, re-epithelialization and revascularization were reported by them. Histological examination of the wound tissue showed evidence of increased population of fibroblasts and a plateau or decreased recruitment of macrophage and neutrophile cells. In the dependent group re-epithelialization was observed to be enhanced significantly in comparison to the control group while having an inhibitory effect on revascularization. The present study demonstrates that morphine dependency enhances re-epithelialization as well as tissue recruitment of fibroblasts; thereby probably enhancing secondary intention wound healing.
