  • Hepatic DNA Damage in Mice Given Organochlorine Chemicals

抄録

The effects of organochlorine chemicals, mainly pesticides, on DNA single-strand breaks (DNA SSB) and the formation of 8-hydroxydeoxyguanosine (8-OHdG) in DNA were examined in mouse liver. Male mice were treated with organochlorine chemicals per os for 5 days, and killed 4hrs after the last administration. The daily dose of each chemical was about one-fifth of the reported LD50. The chemicals examined were endrin, dieldrin, γ-BHC, chlorpyrifos, heptachlor, pentachloronitrobenzene, pp′-DDT, pentachlorophenol, chlordane, 2, 4-D, mirex, pentachlorobenzene, hexachlorobenzene, chlorobenzilate, methoxychlor and trichloroethylene. The administrations of dieldrin, heptachlor, chlordane, mirex, pentachlorobenzene, hexachlorobenzene, chlorobenzilate, and trichloroethylene significantly increased relative liver weight. The 8-OHdG level in hepatic DNA of vehicle-treated mice was 1.2per 105 dG and comparable values were found in all groups treated with the chemicals. Hepatic DNA SSBs in mice treated with trichloroethylene and pentachlorophenol were significantly enhanced, but the effect was slight.
