RESUMEN
AIM:To study the protective effects and mechanism of Fushen Jiangzhuo formula (FSJZ) on the rat renal interstitial fibroblasts with renal tubulointerstitial lesion .METHODS:The serum containing FSJZ and blank con-trol serum were prepared .The rat model of mesangial proliferative glomerulonephritis ( MsPGN) was established and ex-tended the time of modeling to 20th weeks for developing tubulointerstitial lesion naturally .The rat renal interstitial fibro-blasts at the end of 12, 16, 20 week of modeling were isolated and cultured .The effects of FSJZ on the expression of hepa-tocyte growth factor (HGF) and bone morphogenetic protein-7 (BMP-7) at mRNA and protein levels in the pathological re-nal interstitial fibroblasts were determined .RESULTS:The anti-fibrosis factors HGF and BMP-7 were changed in patho-logical renal interstitial fibroblasts .Renal tubulointerstitial lesion significantly down-regulated the expression of HGF and BMP-7, while the drug containing serum of FSJZ significantly up-regulated the expression of HGF and BMP-7.CONCLU-SION:Drug containing serum of FSJZ has protective effect on pathological renal interstitial fibroblasts by regulating the mRNA and protein expression of HGF and BMP-7.
RESUMEN
Objective To study the effect of different extraction parts from Xiongjiang Decoction(XD) on promoting uterine muscle contraction(UMC).Methods UMC in normal mice was measured in vitro by applying serologic pharmacological test.Results Alcohol extracts of XD had an obvious effect on promoting UMC,but the volatile oil and water-extraction alcohol-precipitation extracts had an inhibitory effect.Chloroform part of alcohol extracts had a stronger effect on UMC than other extraction parts.Conclusion The different parts or components extracted from the same decoction have different effects.
