The present study was designed to investigate the in vivo effects of oral administration of arsenic trioxide (As2O3; 0.5 and 1 mg/kg body weight/day for 45 days) on cerebral hemispheres and cerebellum in male mice, Mus musculus. Arsenic reduced the concentration of glutathione (GSH) in cerebral hemisphere and cerebellum at both the dose levels; while increased lipid peroxidation (LPO) in cerebr...

The growing D. discoideum cells were killed in a dose-dependent manner when exposed to 100 and 140 ppm of arsenic (As2O3) at mid-log phase for 20 min. Reduced plaque sizes and changed cell and colony morphologies were observed in the treated cells. Endocytotic functions (both phagocytosis and pinocytosis) were also inhibited in the treated cells. Arsenic treated cell showed a lower DNA and prot...
