作者对病因不明于16～20周流产胎儿5例进行研究,经父母同意取其脑、肺、心、肝、肾、肌肉及皮肤各约0.5g。将含有已知量的目的元素的标准试剂与上述试剂,置于同一条件的原子炉中进行热中子照射,以放射分析法测定其中铝(Al)、锰(Mn)、铜(Cu)、锌(Zn)等4种元素的含量。结果Al虽非人体所必需的微量元素,但在本次测定中,上述各脏器中广泛存在,尤以肌肉、皮肤的含量最高(168.7±49.9;108.0±34.7微克/克·干重,单位下同),远比其它脏器含量(37.0±11.5～59.8±17.7)高出2倍以上。Mn在肝与肾脏含3以上,从其它脏器中未检查出来。Cu只从肾脏中检查出来(256.5±48.9)。Zn以肝脏(891±22.6)、肾脏(536.1±370.2)为最高,肺、心脏、皮肤100～140左右,脑62.4±11.9,而从肌肉中未检出。现认为必须微量元素有Zn、Cu、硒(Se)、
The author of the unknown etiology of 16 to 20 abortion fetus in 5 cases to study, by the consent of their parents brain, lung, heart, liver, kidney, muscle and skin of about 0.5g. A standard reagent containing a known amount of the target element and the above reagent were placed in a nuclear reactor under the same conditions and subjected to thermal neutron irradiation. The content of aluminum (Al), manganese (Mn), copper (Cu) Zinc (Zn) and other four kinds of elements content. Results Although Al is not necessary for human body trace elements, but in this determination, the above-mentioned organs are widespread, especially in muscle and skin (168.7 ± 49.9; 108.0 ± 34.7 μg / g · dry weight, unit The same below), far more than other organs (37.0 ± 11.5 ~ 59.8 ± 17.7) more than 2 times higher. Mn in the liver and kidney contains 3 or more, not checked out from other organs. Cu was examined only from the kidneys (256.5 ± 48.9). Zn was highest in the liver (891 ± 22.6) and kidney (536.1 ± 370.2), with lungs, heart and skin around 100-140 and brain 62.4 ± 11.9, but not detected in muscle. Now that the necessary trace elements are Zn, Cu, selenium (Se),
