Abstract
BACKGROUND
The goal of the present study was to investigate the wound-healing potential of marine collagen peptides (MCPs) from chum salmon skin administered to rats following cesarean section (CS).
METHODS
Ninety-six pregnant Sprague-Dawley rats were randomly divided into four groups: a vehicle group and three MCP groups. After CS, rats were intragastrically given MCPs at doses of 0, 0.13, 0.38, 1.15 g/kg*bw, respectively. On postoperative days 7, 14, and 21, the uterine bursting pressure, skin tensile strength, hydroxyproline (Hyp) concentrations, and histological and immunohistochemical characteristics of the scar tissue were examined.
RESULTS
In the MCP groups, the skin tensile strength, uterine bursting pressure, and Hyp were significantly higher than those in the vehicle group at all three time points (p<0.05). The formation of capillary, fibroblast, and collagen fiber, the expression of platelet-endothelial cell adhesion molecule-1, basic fibroblast growth factor, and transforming growth factor beta-1 were increased in the MCP groups (p<0.05).
CONCLUSION
MCPs could accelerate the process of wounding healing in rats after CS.
