摘要：Bisphenol A (BPA) is active in immature AP rat uterotrophic assays when evaluated using either the oral or the subcutaneous (sc) injection routes of exposure (three daily administrations of 400-800 mg/kg BPA). Premature vaginal opening was seen for 8 of 14 animals exposed to 600 and 800 mg/kg BPA by sc injection. Vaginal opening was not produced by BPA in the gavage studies. These results are consistent with those of Dodds and Lawson [Nature 137:96 (1936)] who found that BPA induces persistent vaginal cornification in ovariectomized rats exposed to three twice-daily injections of 85 mg/kg BPA (total daily dose 170 mg/kg), but they conflict with the reported inactivity of BPA in the immature mouse uterotrophic assay. The uterotrophic activity of diethylstilbestrol in the rat is also established (0.04 mg/kg/day for three days). Full text Full text is available as a scanned copy of the original print version.
