Abstract

Concentration of 5 elements (Ca, Cu, Fe, Mg, Zn) in 10 organs (brain, heart, lung, liver, kidney, spleen, testis, thymus, salivary gland and bone) and serum of rats were determined by inductively-coupled argon plasma atomic emission spectrometry (ICP). Samples were digested with nitric acid and perchloric acid in a sealed double Teflon vessel with polypropylene jacket by heating with a microwave oven. The concentration of 5 elements in the organs can be grouped into 5 categories as follows. (1) heart, liver and spleen (Mg > Fe > Ca > Zn > Cu) (2) lung and kidney (Mg > Ca > Fe > Zn > Cu) (3) brain, thymus and testis (Mg > Ca > Fe = Zn > Cu) (4) serum and bone (Ca > Mg > Fe = Zn > Cu) (5) salivary gland (Ca = Mg > Fe > Zn > Cu).

摘要

采用电感耦合氩等离子体原子发射光谱法（ICP）测定大鼠10个器官（脑、心、肺、肝、肾、脾、睾丸、胸腺、唾液腺和骨骼）及血清中5种元素（钙、铜、铁、镁、锌）的含量。样品在带聚丙烯外套的密封双层聚四氟乙烯容器中用硝酸和高氯酸消化，通过微波炉加热。器官中5种元素的含量可分为以下5类：（1）心脏、肝脏和脾脏（镁＞铁＞钙＞锌＞铜）；（2）肺和肾脏（镁＞钙＞铁＞锌＞铜）；（3）脑、胸腺和睾丸（镁＞钙＞铁 = 锌＞铜）；（4）血清和骨骼（钙＞镁＞铁 = 锌＞铜）；（5）唾液腺（钙 = 镁＞铁＞锌＞铜）。
