摘　　要：By using the Ladisch partitioning and microscale-analysis of HPTLC,the comparative quantitative and qualitative studies of gangliosides (Gg)and neutral glycosphingolipids(N-GSL)compositions from human chorionic villi tissues of normal early pregnant women and women treated with mifepristone, norethisterone(NET)and tamoxifen(TAM)were reported in this paper.The patterns of Gg and N-GSL in three treated groups were similar to those in normal pregnant group.The total values of Gg from the chorionic villi tissues reduced significantly in three treated groups(P<0.01).In all treated groups,the amounts of NeuNAC-Gal-Glc-cer(GM3),NeuNAC-NeuNAC-Gal-Glc-cer(GD3)and Gal-GalNAC-(NeuNAC)-Gal-Glc-cer(GM1)were decreased significantly compared with those in normal(P<0.01orP<0.05).In NET and TAM groups,Neu NAC-Gal-GalNAC-(NeuNAC-NeuNAC)-Gal-Glc-cer(GT1b) was markedly lower than that in normal(P<0.01).The total values of N-GSL extracted from the chorionic villi tissues were obviously higher in mifepristone and TAM groups than those in normal(P<0.01).The Gal-Glc-cer(LacCer)(CDH)and Gal-Gal-Glc-cer(Gal-LacCer)(CTH)were greatly increased in mifepristone group as compared with normal P<0.05).Paragloboside:Gal-GalNAC-Gal-Glc-cer(PG)in NETgroup was significantly higher than that in normal(P<0.01).By using the Ladisch partitioning and microscale-analysis of HPTLC,the comparative quantitative and qualitative studies of gangliosides (Gg)and neutral glycosphingolipids(N-GSL)compositions from human chorionic villi tissues of normal early pregnant women and women treated with mifepristone, norethisterone(NET)and tamoxifen(TAM)were reported in this paper.The patterns of Gg and N-GSL in three treated groups were similar to those in normal pregnant group.The total values of Gg from the chorionic villi tissues reduced significantly in three treated groups(P<0.01).In all treated groups,the amounts of NeuNAC-Gal-Glc-cer(GM3),NeuNAC-NeuNAC-Gal-Glc-cer(GD3)and Gal-GalNAC-(NeuNAC)-Gal-Glc-cer(GM1)were decreased significantly compared with those in normal(P<0.01orP<0.05).In NET and TAM groups,Neu NAC-Gal-GalNAC-(NeuNAC-NeuNAC)-Gal-Glc-cer(GT1b) was markedly lower than that in normal(P<0.01).The total values of N-GSL extracted from the chorionic villi tissues were obviously higher in mifepristone and TAM groups than those in normal(P<0.01).The Gal-Glc-cer(LacCer)(CDH)and Gal-Gal-Glc-cer(Gal-LacCer)(CTH)were greatly increased in mifepristone group as compared with normal P<0.05).Paragloboside:Gal-GalNAC-Gal-Glc-cer(PG)in NETgroup was significantly higher than that in normal(P<0.01).
