    Abstract:
    8-Hydroxydeoxyguanosine (8-OH-dG) levels were examined in liver and kidney DNA after di(2-ethylhexyl)phthalate (DEHP), di(2-ethylhexyl)adipate (DEHA) and phthalic anhydride administration to male 6-week-old F-344 rats in the diet at concentrations of 1.2, 2.5 and 1.5%, respectively. Significant increases in 8-OH-dG levels were observed only in the liver (target organ of DEHP and DEHA carcinogenesis) DNA after 1 and 2 weeks of treatment with DEHP and DEHA, respectively. The results suggest the involvement of oxidative DNA damage in hepatocarcinogenesis by peroxisome proliferators.
