    Abstract:
    The effects of four hexose sugars (D-glucose, D-fructose, D-galactose, D-mannose) on the developing granulation tissue in rats were examined. Cylindrical hollow sponge implants were used as an inductive matrix for the growth of granulation tissue. In the test group, the implants were injected with 0.1 ml of solution containing the different hexoses in 0.01, 0.1 and 1 M concentrations daily for 7 days while the implants of the control groups were injected with 0.1 ml of phosphate-buffered saline solution only. Analyses of granulation tissue and wound fluid in the sponge implants were carried out 7 days after implantation. The results demonstrated that galactose caused a significant increase in the accumulation of granulation tissue as estimated by histological analyses, but no significant differences were observed in various chemical analyses. In striking contrast, statistically significant decreases were observed in the number of leukocytes in wound fluid, in the amount of DNA, RNA, collagen hydroxyproline, nitrogen, hexosamines and uronic acids in sponges treated with 0.1 or 1 M mannose, reflecting decreased granulation tissue formation. This effect was also observed in histological analyses of the specimens. There were no major changes in sponges treated with glucose or fructose. In summary, the findings of the present study demonstrate that galactose may enhance wound healing and mannose treatment inhibits the inflammatory reaction in wound healing and decreases granulation tissue formation in an experimental wound model.
