Results and discussion

Results: maternal animals

Effect levels (maternal animals)

Remarks on result:
other: No deaths or dose dependent changes in kg bw/ or uterine weight were identified. However in line with the findings from repeat dose studies, changes were observed in liver, lung and spleen weight in the mothers.
