Electron spin resonance (ESR) spectrum of paraffin embedded human liver tissue. A possible method for the estimation of copper content. 1979

G Elek, and K Lapis, and A Rockenbauer

Human liver tissues embedded in paraffin wax for histological examination have been studied by Electron Spin Resonance (ESR) spectroscopy. A signal was detected at g approximately 2.05 section of the spectrum. The amplitude of this signal was correlated with the copper content of the embedded specimens measured by flame atomic absorption technique. The positive correlation which has been found can make ESR spectroscopy suitable for estimating the copper content of tissues without damaging the sample. The limits and errors of this method have also been analysed.

D003300	Copper	A heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55.	Copper-63,Copper 63
D004578	Electron Spin Resonance Spectroscopy	A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
