Abstract
OBJECTIVE: To comprehensively evaluate bioadhesive properties these materials by testing adhesion properties in vitro and in vivo. METHODS: Mucin from porcine stomach model, homemade adhesion measuring device and intestinal propulsion were used for in vitro and in vivo evaluation adhesive materials. RESULTS: Carbomer 934P and HPMCK100M with high viscosity had optimal adhesion in their class, besides chitosan can be specifically bound by mucin from porcine stomach and it performed better than other materials in vivo adhesion. CONCLUSION: Above researches indicate that the bioadhesive properties had a positive correlation with viscosity in the same type material, and the relative molecular mass the materials, moisture absorption capacity, specific binding mucin and other factors should be considered in different types materials in the comprehensive evaluation.
