摘要：The mutagenic/carcinogenic activities of DEHP and MEHP were studied in bacteria and mammalian cells. MEHP but not DEHP exerted a dose-dependent DNA damaging effect to B. subtilis in Rec-assay. DEHP and MEHP showed mutagenic activities to S. typhimurium TA-100, with and without S-9 mix, respectively. MEHP produced not only the mutation in E. coli WP2B/r but also sister chromatid exchanges (SCE) in Chinese hamster V79 cells. It also induced 8AG/6TG-resistant gene mutations and chromosomal aberrations in the V79 cells. Transplacental administration of DEHP or MEHP to the Syrian golden hamster embryos was carried out by administering DEHP or MEHP to gravid animals on day 11 of gestation, followed by the cultivation of embryonic cells for 15-20 days. Both DEHP and MEHP induced 8AG/6TG-resistant mutation, chromosomal aberrations and morphological transformation in the embryonic cells of the Syrian golden hamster.
