本文用等离子光量计对昆明小鼠经急性重复缺氧１、２、４次及急性重复缺氧４次后饲养２天，其脑组织中磷、钾、钙、镁等４种宏量元素及铅、金、铝、钛、镉、铋、镓、银、钡、锶、铟、镧、铈、钇、钪、铍等１６种微量元素的溶解态、非溶解态及总含量进行了测定，以未经急性重复缺氧的动物为对照组，同时测定其脑组织中相应的元素含量。实验组动物脑组织中各元素含量与对照组相比，发现钾、金、钛、铟、铈、钇、镓、银、钡、镧、铍等１１种元素的含量在不同实验组、不同状态下有改变。结果提示，动物经急性重复缺氧，对其脑组织中多种元素的含量有一定影响。这一实验结果对揭示急性重复缺氧可引起动物神经系统的生理生化变化有一定的意义。
In this paper, Kunming mice were treated with acute and repeated hypoxia 1,2,4 times and acute repeated hypoxia for 4 days after feeding for 2 days. The contents of four macro elements (phosphorus, potassium, calcium and magnesium) The dissolved, non-dissolved and total contents of trace elements including lead, gold, aluminum, titanium, cadmium, bismuth, gallium, silver, barium, strontium, indium, lanthanum, cerium, yttrium, scandium and beryllium were measured. Animals without acute hypoxia were used as control group, and the corresponding elements in brain tissue were also determined. Compared with the control group, the contents of 11 elements in the brain tissue of the experimental group were found to be significantly different among the experimental groups, the different states, the concentrations of potassium, gold, titanium, indium, cerium, yttrium, gallium, silver, barium, There are changes. The results suggest that animals with acute repeated hypoxia, its content of various elements in the brain have a certain impact. The results of this experiment reveal some acute hypoxia can cause physiological and biochemical changes in the nervous system of a certain significance.
