Abstract:Objective To investigate the influence of Celecoxib on the secretion of inflammatory cytokines in RAW 264.7 macrophages model induced by lipopolysaccharide(LPS).Methods Mouse RAW 264.7 macrophage was cultured. 24 h after mouse RAW 264.7 macrophage was stimulated by LPS 1 μg/ml,then cell culture medium was collected.NO was tested by using Griess and the content of TNF-α and PGE2was tested by ELISA.Then the RAW 264.7 macrophage inflammation model was established.The toxic effect of celecoxib on LPS stimulated RAW 264.7 macrophages assayed by MTT.8.00 μmol/L Celecoxib was used to pretreat cell for 1 h,following of 1 μg/ml LPS added to stimulate cell for 24 h. Cell culture medium was collected to test the content of inflammatory factors NO,TNF-α and PGE2in culture medium. Results After 1 μg/ml of LPS stimulated RAW macrophages for 24 h,cell morphology changed obviously,the content of inflammatory factors NO,TNF-α and PGE2in culture medium were obvious higher than those of the control group(P<0.01).Compared with DMSO control group,8.00 μmol/L Celecoxib group could significantly inhibit the release of inflammatory cytokines NO,TNF-α and PGE2induced by LPS in RAW 264.7 cells(P<0.01).Conclusion Establishment of LPS induced macrophage model of RAW 264.7 and celecoxib can obvious inhibit the release of inflammatory cytokines NO,TNF-α and PGE2.
