[Objective] To study the effect of perfluorooctane sulfonate (PFOS-K)on the liver development in embryo of mice and the toxicity in the embryo.
[Methods] PFOS-K solution with concentrations of 3mg/kg and 12 mg/kg in a cumulative dose series was infused through gavage into nine-day-pregnant mice. Then, 4 days after the treatment the expression of signal transduction and activators of transcription 3(STAT3) protein in the embryo liver were measured by immunohistochemistry.
[Results] The expression rates of SATA3 protein in mice with dose 3 mg/kg and 12 mg/kg were 41.62% and 14.77%, respectively. The results showed significant difference (P<0.01).
[Conclusion] The results showed that PFOS-K could affect the expression amount of STAT3 protein in the embryo liver development. It could be concluded that PFOS-K has certain damage to the liver cell in embryo of mice.
