Any other information on results incl. tables

All rats at the 1600 and 3200 mg/kg bw/d doses died or were sacrificed moribund prior to the end of treatment. Treated animals were inactive, ataxic, prostrate and dyspnoeic. Histologically, rats showed changes in the brain, liver, spleen and testes. Reticulocyte counts and methaemoglobin levels were increased (all dosage groups); haemoglobin and red blood cells were decreased. No quantitative details on blood parameters included in the report.
