Hair as a biopsy material V. Hair metal as an index of hepatic metal in rats: copper and zinc

Abstract
Hair copper in 500 day-old adult rats was found to correlate directly with copper in whole liver (P < 0.001) and the subcellular liver nuclear (P < 0.022), and cytosol fractions (P < 0.001). An inverse correlation was found between copper in liver microsomes and plasma cholesterol (P < 0.044). Similar data analysis for zinc showed no significant correlations (P > 0.05). The determination of copper in hair may be useful for assessing total liver copper content in human beings. Copper in liver microsomes may participate in the control of plasma cholesterol.
