Background There is growing evidence for the role of oxidative damage in chronic diseases. Although ozone (O3) is an oxidant pollutant to which many people are exposed, few studies have examined whether O3 induces oxidative stress in humans. Objectiv

Analysis of carcinogen-DNA adducts has been regarded as a useful means of assessing human exposure to chemical carcinogens. We have established a method for quantitation of 4-aminobiphenyl (4-ABP)-DNA adducts by alkaline hydrolysis and gas chromatogr

Correlations of blood polychlorinated biphenyl (PCB) levels or PCB patterns and blood pressures were studied in 59 patients with yusho (PCB poisoning) above 40 years old. In spite of the passage of 13 years from the onset, 52.5% of these patients sti
