The preventive effect of ambroxol hydrochloride chitosan on postoperative intraperitoneal adhesion formation in a rat model.

BACKGROUND

This study aimed to investigate the effects of ambroxol hydrochloride chitosan reduced the degree of peritoneal adhesion.

METHODS

A total of 120 Sprague-Dawley (SD) rats were experimented, group A: the damaged peritoneal was covered with ambroxol hydrochloride chitosan, group B: chitosan membrane only, group C: nothing. Enzyme-linked immunosorbent assay (ELISA), western blotting, and immunohistochemistry (IHC) were used to observe the expression of TNF-α and NF-κB p65.

RESULTS

TNF-α and NF-κB p65 in group A significantly decreased in comparison with the controls. IHC showed TNF-α and NF-κB p65 were significantly down-regulated in group A. Adhesion grade in the treatment group was significantly lower than in controls.

CONCLUSION

Ambroxol hydrochloride chitosan reduced the degree of peritoneal adhesion.
