Any other information on results incl. tables
LD50 for rats was 250.54 mg/kg. Compared with the control group, organ body coefficient of liver in high and middle dose groups showed significant difference as well as that of lung in female rats in high dose group. The leucocytes of rats and the proportion of neutrophils significantly increased in all treated groups. The platelet in female rats of high dose group increased. The serum creatinine of female rats increased in high dose group. The pathological examination did not show any abnormality in all treated groups.
Nano-FeO3-Glu belonged to common drug, which had not led to pathological changes although it induced certain effect on blood system, liver and kidney function and there is difference in pathological changes between males and females.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
