Effect of trivalent and hexavalent chromium on renal and hepatic tissue glycogen metabolism of a fresh water teleost Anabas scandens.
The in vivo toxic impact of chromium in its two forms (trivalent and hexavalent) on glycogen metabolism in the liver and kidney of a fresh water teleost Anabas scandens was studied. In a sub-chronic exposure of 30 days, depletion of glycogen and glucose reserves reflected in the activity patterns of glycogen phosphorylases 'a and ab'. While both forms of chromium induced alterations in enzyme activities and metabolite levels in the two tissues, Cr(+6) exerted greater effects in the kidney.
