Results and discussion

Results: maternal animals

Maternal developmental toxicity

Details on maternal toxic effects:

Maternal toxic effects:yes

Details on maternal toxic effects:
In the highest dose, body weights of both males and females in both treated generations were sporadically and not always statistically significant decreased compared to controls.
At necropsy organ weight differences in liver, lung, kidney and heart were observed in the F1 generation, but no pathological findings were associated with the affected organs.
