Abstract:
Objective To investigate the relation of changes of fetal bile acid and morphologic ultrastructure of human placental syncytial cells in intrahepatic cholestasis of pregnancy (ICP). Methods(Total bile acid of cord venous blood was measured by cycle enzyme method between intrahepatic cholestasis of pregnancy and control groups after birth. The ultrastructure of human placental syncytial cell was analyzed by morphologic study in two groups. Results (1) The total bile acid of cord venous blood in ICP group was significantly higher than in control group[(8.6?3.2) ?mol/L vs (4.6?1.5)?mol/L ](P0.05). The average volume, surface area density and volume density of mitochondrion in ICP group [respectively (0.0200?0.0020) ?m~3,(0.600?0.010) ?m~2/?m~3,(0.0800?0.0090)?m~3/?m~3] were significantly enlarged than in control group [respectively (0.0100?0.0050)?m~3, (0.500?0.030) ?m~2/?m~3,(0.0500?0.0020) ?m~3/?m~3](P0.05). Conclusion In ICP, high levels of bile acids may impair cellular organelle, resulting in abnormality of physiological function of syncytial cells, and affecting the synthesis and transportation functions of placenta.
