Expression of vascular endothelial growth factor and tumor necrosis factor-alpha in synovium of rats with adjuvant arthritis / 中国病理生理杂志

ABSTRACT

AIM: To investigate the expression of vascular endothelial growth factor (VEGF) and tumor necrsis factor-alpha (TNF-?) in synovium of rats with adjuvant arthritis (AA) and the relationship between the pathological score and the expression of VEGF and TNF-? protein. METHODS: AA was produced in Wistar rats by inoculating complete Freund's adjuvant (CFA). The arthral pathological score was calculated, production of VEGF and TNF-? protein were assayed by histoimmunochemical staining at different stage after CFA inoculation. RESULTS: In AA group, the pathological score and expression of VEGF protein in synovium increased significantly (P
