In rat hepatocytes, we examined the relationship between cell volume, bleb formation, and loss of cell viability during chemical hypoxia with KCN plus iodoacetic acid. In hypotonic media (150-200 mosmol/kgH2O), cells swelled to a greater extent during chemical hypoxia than in isotonic media, but
Little is known about changes in the amount of iron in the intracellular low molecular weight pool, which catalyzes the Fenton reactions during reperfusion after ischemia. In this study a new approach is presented to measure low molecular weight iron and it is applied to normal hearts during
The massive leakage of intracellular enzymes which occurs during reoxygenation of heart tissue after hypoxic or ischemic episodes has been suggested to result from the formation of oxygen radicals. One purported source of such radicals is the xanthine oxidase-mediated metabolism of hypoxanthine and
The antinecrotic potential of a new drug, 3-palmitoyl-(+)-catechin (PC), which is a derivative of (+)-cyanidanol-3, was studied in two different experimental models of necrosis of the liver in the rat: acute hepatitis induced by galactosamine and liver damage induced by a combination of chronic
