本文到用从人胎盘后血青中提取的SP_1纯品,免度家免,获得了SP_1抗血清,并建立了SP_1单向屯疫扩散去。作者用比法寸妊娠23～11孕同的正常孕扫进行了观察,建立了36～11孕妇的临界值。SP_1≤100μg/ml为异常值,SP_1值>100μg/ml为正常值,此外对高危妊艰孕扫进行了观察。我仃认为测定孕妇血青SP_1水平可做为检查胎盘功能,监护高危妊娠的一项较好的指标。 In this paper, SP_1 antiserum was obtained from pure SP_1 extracted from human placental blood serum, and SP1 unidirectional tunogenic spread was established. The authors used gestational gestational 23 ~ 11 pregnant with the same normal pregnancy were observed, established 36 to 11 pregnant women, the critical value. SP_1≤100μg / ml as abnormal value, SP_1 value> 100μg / ml as normal value, in addition, the observation of high risk pregnant sweeping was observed. I Ding that the determination of serum SP_1 levels in pregnant women can be used as a check placental function, monitoring of high-risk pregnancy a better indicator.
