METHODS: The subjects were divided into three groups: H pylori-infected cholecystitis group, H pylorinegative cholecystitis group and control group. Pathologic changes of the gallbladder were observed by optic and electronic microscopes and the levels of interleukin-1, 6 and 8 (IL-1, 6 and 8) were detected by radioimmunoassay. RESULTS: Histological evidence of chronic cholecystitis including degeneration, necrosis, inflammatory cell infiltration, were found in the region where H pylori colonized. Levels of IL-1, 6 and 8 in gallbladder mucosa homogenates were significantly higher in H py/oriinfected cholecystitis group than those in Hpylorinegative cholecystitis group and control group. CONCLUSION: H pylon infection may be related to cholecystitis.展开更多
