DIESEL EXHAUST AFFECTS THE ABNORMAL DELIVERY IN PREGNANT MICE AND THE GROWTH OF THEIR YOUNG

Tsukue, Naomi, Tsubone, Hirokazu, Suzuki, Akira K.·2002·Inhalation Toxicology

Abstract

To clarify the toxic effects of diesel exhaust (DE) on delivery in mice and on growth of young, C57Bl-strain females were exposed to 0.3, 1.0, or 3.0 mg diesel exhaust particles (DEP)/m3 or filtered clean air (control) for 4 mo (12 h/day, 7 days/wk). After exposure, some females from each group were examined by necropsy, and the remainders were mated with unexposed males. Estrous females for necropsy who had been exposed to 1.0 mg DEP/m3 had significantly lower uterine weights than the control estrous females. In the mated females, 9.1, 10.0, or 25.0% (0.3, 1.0, or 3.0 mg DEP/m3 of the pregnancies resulted in abnormal deliveries (abortion and unable delivery), but this was not significant. The rate of good nest construction by delivered females exposed to 3.0 mg DEP/m3 was significantly lower. Young were weighed at 11, 14, and 21 days, and weekly from wk 4 to 9 after birth. Body weights of male young of dams exposed to 1.0 or 3.0 mg DEP/m3 were significantly lower at 6 and 8 wk of age. Body weights of female young of dams exposed to 1.0 or 3.0 mg DEP/m3 were also significantly lower at 6, 8, and 9 wk. Vaginal orifices of young female mice whose dams were exposed to 0.3 and 1.0 mg DEP/m3 opened significantly earlier. The young were killed at 30 or 70 days during deep anesthesia, and their body weights, organ weights, and body lengths were measured. Anogenital distance (AGD) of 30-day-old males whose dams were exposed to 0.3 mg DEP/m3 was significantly shorter than that of the…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
