title: Distribution of 9 trace metals in 17 anatomic sites of dog heart tissue and their classification using pattern recognition.
abstract: The concentrations (geometric means of 11 determinations) of 9 trace metals in 17 anatomic regions of dog heart tissue and blood vessels were determined. The relationships recognized within the set of trace metal profiles were comparable to those reported earlier for the cardiovascular systems of pig [J. Mol. Cell Cardiol 6, 383 (1974)] and those of beef [Bioinorg, Chem. (in press)]. These included differences in trace metal concentrations that allowed differentiation of the following tissues from each other: (1) ordinary and specialized myocardium from blood vessels and heart valves, (2) blood vessels from heart valves and (3) arterial from venous tissues.
