Applicant's summary and conclusion

Executive summary:

The test substance was applied by repeated introduction in stomach for 22, 45, or 90 days. Animals were observed for mortality and clinical signs.

Doses of 1/5, 1/10, and 1/20 LD50 (total cumulative dose= 4.5 times LD50; LD50= 975 mg/kg bw in rats and mouse). These doses did not provoke the death of animals; an increasing excitement, body weight loss, and respiratory effects were found.
