妊娠期检测血清白细胞介素-10的临床意义

open access: yesZhongguo shiyan zhenduanxue, 2011
目的通过对妊娠女性不同时期检测血清中自细胞介素-10(IL-10),探讨妊娠女性不同时期机体免疫状态变化的相关性研究。方法取63例不同孕期妊娠女性和21例未孕女性血清,应用双抗体夹心ELISA法动态检测四组血清IL-10值。结果妊娠早期妊娠女性血清IL-10浓度为351.2±27.3(pg/ml);妊娠中期妊娠女性血清IL-10浓度为224.5±23.6(pg/ml)、妊娠晚期妊娠女性血清IL-10浓度为103.6±21、7(pg/ml),非妊娠期女性血清IL-10浓度为为92.5±21.6(pg/ml)
