[Effect of melatonin on wound healing and various biochemical characteristics of granulation-fibrous tissue in rats].

The influence of melatonin application on wounds healing and biochemical composition of rat regenerating granulation tissue was studied. Melatonin decreased healing rate of wounds. The differences in electrophoretic pattern of proteins extracted by neutral saline solutions were detected. Melatonin increased quantity of neutral soluble collagen fraction and gene expression of minor types of collagen in normal skin. Spectrum of glycosaminoglycans' was changed, and earlier increase of chondroitinsulfats induced by administration of melatonin was observed.
