EC number: 203-804-1 | CAS number: 110-80-5
rabbit (Gross E): albuminuria, hematuria (see also more details in publication: Gross E., cited in Patty F.A., 1963)
Results subchronic oral gavage rat (13 weeks):
At doses of 50, 100 and 100/400 µL/kg/day (increased dosage from 100 to 400 µL/kg at day 59 of the study period) no treatment related systemic changes in the analysed organs were observed. The administration of 200 µL/kg/day resulted in all 5 male rats in obvious changes in the testes (interstitium loosened oedematously). In the tubuli there was a lack of the last ripening step from the normally arranged germinal epithelium to the spermatocytes. In the spleens of all animals haemosiderin deposits were observed. Nearly same results were observed in the dose group 200/800 µL/kg/day (increased dosage from 200 to 800 µL/kg at day 59 of the study period).
Results subchronic oral gavage (gelatine capsules) dog (13 weeks):
At doses of 50 and 100 µL/kg/day no macroscopic nor histological treatment related systemic changes in the analysed organs were observed. At 200 µL/kg/day changes of the testes in the 3 male dogs were seen. In 2 male and one female slight changes were observed at the kidneys.
Summarised results (rat and dog):
Mortalities: none (13 wk rat study; 11d dog study; 13 wk dog study)
Symptoms: none (13 wk rat study; 11 d dog study; 13 wk dog study)
Body weight development: at dosage including level 800 µl/kg/d from day 60 on slightly retarded for males (13 wk rat study); 1 and 3 kg, 2 and 2.6 kg (11 d dog study); no effect (13 wk dog study)
Feed consumption: at dosage including level 800 µl/kg/d from day 60 on reduced (13 wk rat study); not measured (11 d dog study); no effects (13 wk dog study)
Hemoglobin and hematocrite:
no effect (11 d dog study)
13 wk rat study:
13 wk dog study:
Results on developmental toxicity:
The administration of 0, 12.5, 25, 50, 100, 200, or 400 µL/kg/day during gestation (day1 to day 21) resulted in a NOEL for the rat of 25 µL/kg/day. As this value was the lowest according to the complete study results of Stenger et al. (1971), the author of this IUCLID dossier considered this low value also as the overall NOEL for this endpoint.
