Objective:To explore the underlying molecular mechanisms of specific cyclooxygenase-2 inhibitor(Rofecoxib)and to evaluate its efficacy on MRL/lpr mice.Methods:12-week female MRL/lpr mice were given Rofecoxib (10mg·kg -1 ·d -1 )for 12 weeks.Suppressive effect of the drugs on serum and urinary levels of tumor necrosis factor-α(TNF-α)
interleukin-6(IL-6) and urinary TXB 2 level were determined by using radio-immunological assay.Changes in proteinuria
serum creatinine
pathology of ltidney and the expression of CD14 in renal tissues were observed.Results:Compared with the ones in the control group
mice treated with Rofecoxib had lower levels of proteinuria( P <0.01)
serum creatinine( P <0.01)
urinary TXB 2 ( P <0.01)
TNF-α and IL-6( P <0.05) and the thickness of glomerular base membrane (GBM) ( P <0.05).The number of CD14 expression of the positive cells in renal tissue significantly decreased.Conclusion:TNF-α and IL-6 may take part in immune pathogenesis of lupus nephritis(LN).Serum and urinary levels of TNF-α
IL-6 may be useful indicators for monitoring disease degree of renal damage in LN.Rofecoxib may have a significant effect on inhibiting the production of INF-α
IL-6 in the monocytes/macrophages cells.Rofecoxib may decrease the levels of serum and urinary TNF-α
IL-6 and ameliorate renal injuries in lupus MRL/lpr mice.The specific cyclooxygenase-2 inhibitor has a renoprotective effect on MRL-lpr/lpr mice.
