RT Journal Article ID 2489ffaa0ec18b0f A1 Singh, Amarjit A1 Kalla, Natwar R. A1 Sharma, Raj P. A1 Sharma, Rajeshwar T1 Effects of Hexaammine Cobalt (III) Chloride on Oxidative Stress-Related Parameters and Drug Metabolizing Enzymes in Mice JF Journal of Environmental Pathology, Toxicology and Oncology JO JEP(T) YR 2007 FD 2007-05-30 VO 26 IS 1 SP 1 OP 8 AB Hexaammine cobalt (III) chloride has been advocated as a potential anticarcinogenic compound. There is no information on the effects of this compound on oxidative stress-related parameters in animals. In the present study the effects of administration of hexaammine cobalt (III) chloride in drinking water to balb/c male mice at doses of 25, 50, and 100 ppm for 14 weeks were examined. The tissue distribution of the compound was seen in liver, kidney, lung, intestine, blood, and spleen. The effects of the compound were monitored on levels of lipid peroxidation, GSH content, and activities of SOD, catalase, GST, and Cyt P450, along with the liver and kidney function tests. The results show that the cobalt accumulated maximally in kidney followed by liver, intestine, blood, spleen, and lung in decreasing order, in a dose-dependent manner. GSH and GST also showed increase in a dose-dependent manner while SOD and catalase showed increase with the highest dose only. Liver and kidney function tests showed no untoward change with any dose at the end of the study. The results suggest an antioxidant potentiating effect of the hexaammine cobalt (III) chloride besides nontoxicity to liver and kidney. Since the ability to induce an increase of GSH and GST along with other detoxifying enzymes by anticarcinogenic agents has been reported to correlate with the inhibition of tumorigenesis, the cobalt complex might qualify as a potential cancer chemopreventive agent.
