【摘要】 目的　探讨羊水板层体计数 (L am ellar body count,L BC)预测胎肺成熟度的价值。　方法　采用库尔特 Micro Diff II全自动血细胞分析仪对 41例正常足月妊娠剖宫产时的羊水标本进行L BC的测定 ,并对同一标本采用薄板层析法测定了卵磷脂 /鞘磷脂比值 (L ecithin- sphingomyelin,L / S比值 )。　结果 (1)正常足月妊娠时羊水 L BC为 (86± 43)× 10 3 (范围 72 .5× 10 3 ～ 99.4× 10 3 )。 (2 )羊水 L BC与 L / S比值之间存在正相关 ,r=0 .6 6 ,P=0 .0 0 1。　结论　羊水 L BC是一种快速、准确地判断肺成熟度的方法更多还原

【Abstract】 Objective To discuss the value of amnionic fluid lamellar body count(LBC) as a predictor of fetal lung maturity. Methods Amnionic fluid was obtained during the cesarean section of 41 normal term pregnancies. LBC was performed on each specimen, and lecithin-sphingomyelin(L/S) ratio was detected simultaneously. Results (1)Amnionic fluid LBC was (86±43)×10 3 (72.5×10 3~99.4×10 3) in normal term pregnancy. (2) Positive correlation was shown between the amnionic fluid LBC and L/S ratio(r=0.66,P=0.001). Conclusion The LBC is a rapid and accurate method to determine the fetal lung maturity.更多还原
