The phospholipid-hydrolyzing activity of rat liver lysosomes has been studied. These lysosomes contain a phospholipase that cleaves both fatty acid ester linkages of lecithin and of phosphatidyl ethanolamine and releases free fatty acids from both po

The purpose of this research was to determine the mechanism of damage to protein by the free radical intermediates formed during the peroxidation of lipids. The reaction system consisted of linolenic acid, cytochrome c, and oxygen. The addition react

Fatty acids of mitochrondria from hearts and livers of fresh-water and marine fish, marine birds, fur seal, and from sweet potato have been analyzed by gas-liquid chromatography. Cytochrome patterns, determined from difference spectra, were similar f

Human embryonic diploid lung fibroblasts of the WI-38 line were assayed for the activities of acid hydrolases normally associated with lysosomes. Present in the fibroblasts were: β-acetylhexosaminidases, acid phosphatase, α-glucosidase, β-glucosid

Exposure of rats to low concentrations of ozone (as low as 0.2 ppm) continuously for 8 days, or intermittently (8 hours/day) for 7 days, significantly increased the activities of the glutathione (GSH) peroxidase system in lung tissue. Linear regressi

Lipid peroxidation and DNA damage were evaluated in liver slices incubated for 2 h at 37 degrees C with 1 mM-t-butyl hydroperoxide (t-BOOH), 1 mM-BrCCl3 or 50 microM-ferrous iron. t-BOOH induced the greatest amount of damage to DNA and increased the
