Abstract

Dietary exposure of rats to three different concentrations of zinc pyridinethione (ZPT; 166, 332, 498 ppm) caused delayed onset failure in a treadmill test and, at the higher concentrations (332 and 498 ppm), death. Daily treatment with d-penicillamine (d-PEN) increased the latency period for treadmill failure and lethality. Comparable levels of toxicity were achieved only after d-PEN treated rats had consumed 2-3 times more ZPT than rats not treated with d-PEN. In contrast to ZPT, administration of d-PEN did not affect the onset of treadmill failure associated with acrylamide, p-bromophenylacetylurea or 2,5-hexanedione. Thus, d-PEN provided protection which was selective for ZPT.
