Studies on on Metabolism of RNase Inhibitor, Sialic Acid and Lipids in Human Serum

The serum samples were obtained from the rnaternal and fetal pairs and various cancer patients. The serum levels of RNase inhibitor atd sialic acid were determined and the serum lipid were also separated by the thin-layer chromatography. folio wed by elution and colorimetric determination. The following results were obtained. 1) The serum RNase inhibitors in 12 maternal and fetal pairs showed 28±6% and 18±6% inhibition respectively. and the maternal level is higher than the fetal one with significance( P <0. 01) The maternal level is also higher than the control value of 16±4% with significance( P
