The Determination of Selenium and Sulphur in Human Tissues by Means of Radioactivation Analysis

Abstract

<p> A procedure was established for instrumental radioactivation analysis of selenium in biological materials using se77m, and used to determine selenium bound to plasma and cells of blood from 254 normal individuals. Variations with time, age, sex and hematocrit were investigated. Analysis of subfractions of plasma and cells indicated the highest selenium concentration in the plasma alpha and beta globulins. The selenium content of other tissues was determined for two individuals.</p> <p> A method was devised for instrumental radioactivation analysis of sulphur in dialyzed biological material using s37. The bound sulphur content of samples of plasma and cells from normal human blood was determined. The method would appear to have application in the instrumental activation analysis for other elements in various matrices.</p>
