- Soft tissue examinations: Yes: half per litter
- Skeletal examinations: Yes: half per litter
- Head examinations: Yes: [half per litter ] - Statistics:
- Statistical treatment of the results was conducted where appropriate. Statistical evaluation of equality of means was done by an appropriate one way analysis of variance and a test for ordered response in the dose groups. First, Bartlett's Test was performed to determine if the dose groups had equal variance . If the variances were equal, the testing was done using parametric methods (ANOVA + Dunnett's), otherwise nonparametric techniques were used (Kruskl-Wallis + Dunn's Summed Rank Test). Fetal malformation and variation incidence data were analyzed for statistical significance as follows: First, a standard chi-square analysis was performed to determine if the proportions of incidences differ between the groups tested. Next, each treatment group was compared to the control group using a 2 x 2 Fisher Exact Test.

Details on embryotoxic / teratogenic effects:
There were statistically significant differences in individual skeletal variations, but were limited to an increase in the incidence of rudimentary lumbar ribs in the 400 mg/kg dose group (14.2%) compared with controls (4.2%) on a per fetus basis. This increased incidence was within the historical control range of this laboratory (3.7-28.8), greater than that observed at higher doses, and thus, not considered biologically important. The statistically significant increases in the total fetuses with skeletal variations in the 400 mg/kg dose groups were directly driven by the increased incidence of rib variations and thus, were similarly considered as biologically unimportant (within HC range). - Key result

- Conclusions:
- In conclusion, overt signs of maternal toxicity were not apparent at any dose tested, as indicated by the absence of adverse clinical or postmortem findings or effects on body weight, food consumption, and/or uterine implantation data. Similarly, there were no treatment-related adverse effects on fetal development or growth observed at any dose level tested. Accordingly, the maternal and developmental NOAELs (No Observable Adverse Effect Level) were established at 1000 mg/kg (the limit dose) under the conditions of this study.
- Executive summary:
The test material was administered by oral gavage to three groups of Crl:CDBR female rats at doses of 400, 800, and 1000 mg/kg/day. A fourth group (Group 1) served as a control and received the carrier (corn oil) only. Mated females were dosed once daily from Gestation Day (GD) 6 through GD 15. Dosing volumes were 5 mL/kg for all groups and based on the animals' most recent body weights.
There was no evidence of overt systemic maternal toxicity at any dose level tested. overt signs of maternal toxicity were not apparent at any dose tested, as indicated by the absence of adverse clinical or postmortem findings or effects on body weight, food consumption, and/or uterine implantation data.
Similarly, there were no treatment-related adverse effects on fetal development or growth observed at any dose level tested. There was a statistically significant increase in the incidence of rudimentary ribs in the low dose (400 mg/kg/day) group, but not at the higher doses, compared with controls, which resulted in an increased incidence of total fetuses with skeletal variations in the 400 mg/kg/day group. However, all these incidences were within the historical control range of this laboratory. Therefore, this common finding in fetal rats was not considered biologically important.
Accordingly, the maternal and developmental NOAELs (No Observable Adverse Effect Level) were established at 1000 mg/kg/day under the conditions of this study.
