Abstract

The concentration of 10 elements has been determined in fingernail and hair of four groups representing normal and hepatosplenic (bilharzial) subjects. Samples were collected from rural inhabitants to the east of Alexandria City and irradiated with thermal neutrons from a Triga Mark III Reactor, for 10 minutes. Measurements were made using HPGe detector, ADC and PDP 11/34. The analysis were performed using the RAYGUNprogram. The results showed an increase in the concentration of Al, Cl and I in both fingernail and hair of bilharzial patients than normal while Mg, Ca, K, Mn, Cu, and Sr decreased. Most of the elements showed a higher concentration in fingernail than in hair.

摘要

已测定了四组代表正常人和肝脾（血吸虫病）患者的指甲和头发中10种元素的浓度。样本取自亚历山大市以东的农村居民，并在一台Triga Mark III反应堆中用热中子辐照10分钟。使用高纯锗探测器、模数转换器和PDP 11/34进行测量。分析使用RAYGUN程序进行。结果显示，血吸虫病患者的指甲和头发中铝、氯和碘的浓度高于正常人，而镁、钙、钾、锰、铜和锶的浓度则降低。大多数元素在指甲中的浓度高于头发。
