Abstract: In this paper the authors analyse the trace elements in hair and liver of giant panda by PIXE and test the ratios of trace element contents in liver and hair to Zn separately. Trace elements in the foreleg hair and liver of epileptic and normal giant panda were measured by PIXE. Experimental results show that the K and Fe contents in the liver of diseased giant panda are very much higher than normal giant panda, but the Ca and Cu contents of the latter are significantly higher than the former. The K, Ca, Zn contents in the hair of diseased giant panda are very much higher than normal giant panda, whereas the Fe content of the latter is significantly higher than the former. However the Mn and Zn contents in the liver, the Mn and Cu contents in the hair of the diseased panda do not differ from the normal animal.

摘要: 众所周知,微量元素对生物的生存、健康和疾病有着重大的关系。通过长期的研究,已逐步形成了微量元素医学学科(孔祥瑞,1982;Prosad,A.S.,1976;Underwood,E.J.,1977)。 我们应用PIXE(质子激发X射线)分析方法,对比研究了健康的和有疾病的大熊猫的毛发和肝脏内微量元素的变化,为大熊猫的人工饲养和临床诊断提供一些数据和资料。
