Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 10,000 mg/kg bw for P and F1 generation when CD male and female rats were treated with Barium lithol red orally in diet for 30 month.
- Executive summary:
In a Chronic Toxicity and Potential Carcinogenicity Study,CD male and female rats were treated with Barium lithol redin the concentration of 0 and10,000 mg/kg bw/day orally in diet for 30 month. No mortality, Clinical signs,change in Body weight and Food consumption of treated rats were observed as compared to control. Similarly,No significant effect on reproductive performance of treated rat were observed as compared to control rats. In addition, no effect on reproductive parameters and gross pathologicalof treated rats were observed in treated rat as compared to control.No effect on viability, sex ratio and body weight of pups were observed as compared to control. No external abnormality were observed in pups as compared to control. Therefore, NOAEL was considered to be 10,000 mg/kg bw for P and F1 generation when CD male and female rats were treated with Barium lithol redorally in diet for 30 month.
