作者通过中子活化分析法观察各胎儿期不同脏器中分布的微量元素,推测了各脏器发育中微量元素的正常动态变化,并研究了各脏器发育与微量元素间的生物学关系.对象与方法以怀孕16～20周经流产且无明显疾病因素的5例胎儿为对象,全部病例都进行了病理解剖.在尽量无血液混入的条件下用聚丙烯容器采取部分脑、肺、心脏、肝脏、肾脏、肌肉、皮肤标本(约0.5克)冰冻干燥.把各标本用聚乙烯小袋分装作为反应堆照射用
The author observed the distribution of trace elements in different organs of each fetus by neutron activation analysis, speculated the normal dynamic changes of trace elements in the development of various organs, and studied the biological relationship between the development of various organs and trace elements. Subjects and Methods All fetuses were subjected to pathological examination in 5 fetuses who had abortion with no apparent disease at 16 to 20 weeks of pregnancy.Part of the brain, lungs and heart were taken from a polypropylene container without blood as much as possible , Liver, kidney, muscle, skin specimens (about 0.5 g) were lyophilized.The specimens were packed in polyethylene sachets for reactor irradiation
