title: [Determination of the copper content of liver tissue from paraffin-imbedded samples by electron spin resonance spectroscopy].
abstract: The Electron Spin Resonance spectrum of human liver specimens embedded in paraffin was investigated. An easily registrable mark could be seen in the g 2.05 range of the spectrum. A correlation was detected between the amplitude of this mark of the embedded specimens and the copper content of them measured by a flame ionic-absorptive technique. Authors assume that ESR-spectroscopy is a useful tool for the estimation of the copper content of a specimen, it does interfere with the following histological processing of it. Sources of errors are shortly discussed.
