Abstract:The levels of tumor necrosis factor-α(TNF-α) and Platelet-derived growth factor(PDGF) in human antralmucose of patients with H. Pylori (HP) infection were investigated by radioimmunoassay and bioactivity assay- The resultsshowed that antral TNF-Q and PDGF levels in patients with HP infection were significantly greater than those in patientswithout HP infection and normal controls. TNF-Q level was significantly higher in patients with active gastritis than in thosewith inactive gastritis. In contrast, PDGF activity were raised in both active and inactive gastritis.
