【摘要】 目的:测定早期妊娠母体及绒毛中微量元素铁、锌的含量,并探讨二者的关系。方法:采集12孕周内人工流产患者的绒毛组织及枕后新近长出头发,5∶2HNO3+H2O2体系消解,电感耦合等离子体发射光谱仪(ICP)检测微量元素铁、锌的含量,统计软件SPSS10.0进行数据分析。结果:①绒毛中铁量为(18.26±6.81)μg/g,锌含量为(17.44±10.12)μg/g;母发中铁、锌含量分别为(49.61±34.01)μg/g、(216.39±90.26)μg/g,明显高于绒毛中铁、锌含量(P<0.05)。②绒毛与母体头发中铁含量的相关系数为0.31(P<0.05)、锌含量的相关系数为0.04(P>0.05)。结论:绒毛中铁含量与母发存在正相关性,可以通过检测母亲头发中铁的含量了解胚胎营养状况;而绒毛中的锌与母发中的锌不存在相关性。更多还原

【Abstract】 Objective:To measure the content of essential trace element-iron and zinc in villi and maternal body,and analyze the relationship between them.Methods:The villi tissue and the hair at the back of the patients’ head were adopted when artificial abortion(less than 12 weeks) was operated. Inductively coupled plasma atomic emission spectrophotometry(ICP) was used to measure the content of trace element-iron and zinc. The statistic software SPSS10.0 was applied to deal with the data.Results:①The iron content in villi was (18.26±6.81)μg/g, was less than that in the hair-(49.61±34.01) μg/g. And the zinc content in villi was (17.44±10.12)μg/g, was less than that in the hair-(216.39±90.26)μg/g. ② The coefficient correlation of iron in villi and maternal hair was 0.31(P<0.05), and the coefficient correlation of the content of zinc was 0.04(P>0.05).Conclusion:There is positive corelation between the iron content in villi and that in the hair of maternal body, so the iron content in maternal hair could forecast the nutritional status of embryo.There is no corelation between the zinc content in villi and that in the hair of maternal body.更多还原
