Placental and lactating transfer of {sup 147}Pm in mice

Technical Report:

Abstract

The placental and lactating transfer of {sup 147}Pm in late pregnant mice and lactating mice as well as the distribution of {sup 147}Pm in some organs of mother mice were studied and compared. The pregnant mice and lactating mice had intravenous injection with {sup 147}Pm nitrate at the 17th day of gestation and the next day of parturition respectively. The two groups were sacrified at the 1st, 4th, 9th, 14th and 21st day after the injection. The retentions of {sup 147}Pm in the liver, right femur, uterus, spleen, placenta, fetal membrane and litter were determined by the method of liquid scintillation. The results showed that the amount of {sup 147}Pm in litters of both groups was increasing with the days after injection. In the 1st and 4th day of injection the amount of {sup 147}Pm in litters of lactating mice was 20 times higher than those in litters of pregnant mice. The amount of {sup 147}Pm in livers and skeletons and the half-retention time of prenant and lactating dams were much greater than those of control group.
