Objective:To explore the effect of the Nephritis No.3(N-3)recipe on nitric oxide(NO),nitric oxide synthase(NOS)secreted by cultured mesangial cells(MC)and its gene expression of the in-ducible nitric oxide synthase(iNOS).Methods:The drug(nephritis No.3)-containing serum was preparedwith serum pharmacological technique,and then was applied to react on mesangial cells cultured In fetalcalf serum(FCS)and cells cultured in FCS plus lipopolysaccharide.To observe the secretion of NO andNOS and the gene expression of iNOS by means of RT-PCR.Results:Under the two kinds of culture con-ditions,the content of NO and NOS in the groups with drug-containing serum were higher than thosewithout drug-containing serum(P<0.05,P<0.01),and the expression of iNOS mRNA was up-regula-ted too.Conclusion:The N-3 could significantly promote the secretion of NO and NOS and the mRNA ex-pression of iNOS in rats.
