微量元素为人体正常生命活动所必需,而体内含量低于0.01%的无机元素.正常人体内含铁、铜、锌、锰、硒等几十种微量元素.铜和锌在妊娠期有重要而复杂的生理作用,直接影响胎儿的生长发育,高危妊娠与体内铜、锌含量的异常有关.为此,我们将284例正常妊娠和高危妊娠铜、锌含量及其变化进行对比分析,现报道如下.资料与方法 Trace elements are necessary for human normal life activities, while the content of less than 0.01% in the body of inorganic elements. Normal human body contains iron, copper, zinc, manganese, selenium and other dozens of trace elements. Copper and zinc in pregnancy is important and Complex physiological effects, a direct impact on fetal growth and development, high-risk pregnancy and copper, zinc content of the abnormalities.To this end, we will 284 cases of normal pregnancy and high-risk pregnancy copper and zinc content and its changes were compared, are reported below .Materials and Methods
