环孢霉素A对小鼠妊娠失败模型妊娠预后的影响

Effect of cyclosporin A on prognosis of the abortion-prone murine model

目的 :探讨环孢霉素A(CyclosporinA ,CsA)对小鼠妊娠失败模型及正常妊娠模型妊娠预后的影响。方法 :于孕 4d分别给小鼠妊娠失败模型及正常妊娠模型腹腔注射不同剂量 (0 ,5 ,10 ,15mg kg)CsA ,于孕 14d处死各组小鼠 ,观察各实验组胚胎吸收率、胎鼠及胎盘重量变化。结果 :①CsA可使小鼠妊娠失败模型胚胎吸收率显著降低 ,接近于小鼠正常模型胚胎吸收率 ;同时胎鼠及胎盘重量无显著性差异 ,但有增加趋势。②CsA对小鼠正常妊娠模型胚胎吸收率无明显影响 ;胎鼠及胎盘重量亦无显著性差异。结论 :于孕早期 (胚胎着床期 )腹腔注射CsA可使小鼠妊娠失败模型胚胎吸收率恢复至正常水平 ,从而可能成为保胎的潜在药物。

Objective:To study effect of cyclosporin A(CsA) on the prognosis of the abortion prone murine model.Methods:0,5,10,15 mg/kg CsA were injected intraperitoneally to CBA/J female mice at the fourth gestational day which mated to DBA/2 or BALB/c male mice as an abortion prone model and a successful pregnancy model respectively,thereafter the fetus resorption rate,weight of placenta and fetus were surveyed.Results:CsA could reduce the fetal resorption rate of pregnancy loss model significantly,meanwhile the weight of fetus and plancenta did not have notable alteration,but tendency of the weight increase exists.However,CsA did not affect the fetal resorption rate or the weight of fetus and placenta of the successful pregnancy model.Conclusion:CsA injected intraperitoneally at the early stage of pregnancy could reduce the fetal resorption rate of pregnancy loss model to that of normal pregnancy.The weight of fetus and plancenta appeared to have an increase tendency although non significantly.Therefore,CsA seems to be a potential medicine for protecting pregnancy from abortion.
