Abstract

Experiments were conducted to test the commonly held assumption that analysis of a portion of rat liver is representative of the elemental concentration of the whole organ. Male Sprague-Dawley rats (initial body weight approximately 250 g) fed a chow diet or weanling male Long-Evans rats (initial body weight approximately 50 g) fed a semipurified diet with or without copper in the mineral premix were sacrificed after 4 wk on their respective diets and livers were dissected into seven portions representing major anatomical divisions of this organ. Elemental analyses by atomic absorption spectroscopy (calcium, magnesium, iron, zinc, copper, manganese), atomic emission spectroscopy (sodium, potassium), or colorimetric assay (phosphorus) demonstrated no statistically significant differences in composition of these nine elements among anatomical regions of liver. Dietary copper deficiency led to equivalently reduced copper concentration in all portions of rat liver and did not cause any other significant alterations in liver composition of these nine elements within the 4 wk of these studies. These results confirm the validity of the common assumption that analysis of a portion of rat liver can be representative of the elemental composition of the whole organ. This conclusion will allow more analyses to be performed on fewer animals, thereby reducing animal use and reagent costs without sacrificing analytical accuracy.
