diets containing 0.7 g of sodium tungstate (ICN) per kg of body weight or standard diets (2). In some experiments, sodium molybdate (60 mg/kg in 5.0 mM potassium phosphate buffer, pH 7.4) was given i.p. 6 hr before heart isolation. Rats were injected i.p. with 30 ug of human recombinant IL-la per kg of body weight (specific activity, 3 x 108 units/mg by D10 assay with

reperfusion injury.

Hearts isolated from rats treated 36 hr before with interleukin 1 (IL-1) had increased glucose-6-phosphate dehydrogenase (G6PD) activity and decreased...
