Effects of alpha-MSH on corneal epithelial lesions in rats.


PMID 23390842

Abstract

We investigated the influence of alpha-melanocyte stimulating hormone (alpha-MSH) on the healing of corneal epithelial lesions in male Wistar rats. The lesions were induced by abrading corneal epithelium with a surgical lancet under a biomicroscope. Before the abrasion corneal epithelium was softened with 40% ethanol. alpha-MSH drops in a concentration of 1 x 10(-4) mg/mL significantly promoted epithelial healing, when compared to the control group treated with 0.9% NaCl. Significant reduction of ocular irritation was also observed. Topical alpha-MSH medication could promote the healing of corneal wounds and reduce local inflammatory response without the major side effects of the corticosteroid therapy.
