This study investigated the effects of dietary Ca2+ on branchial Ca2+ and Zn2+ uptake, new and total zinc accumulation in target tissues (gill, liver and kidney), calcium and zinc homeostasis, and acute tolerance to waterborne zinc in fish chronically exposed to waterborne zinc. Juvenile rainbow trout (Oncorhynchus mykiss) were maintained on a calcium-enriched diet [41.2 mg vs. 21.2 mg (control...

Adult male and female albino rats (R. norvegicus) were administered rodenticide, zinc phosphide ranging from 4, 2, 1, 0.5, 0.25 and 0.125% in the diet containing 10(A), 17(B) and 24%(C) protein. Zinc phosphide induced 100% mortality at 4, 2, 1, 0.5% in diet A; 4 and 2% in diet B; and 4% in diet C. The results reveal influence of dietary protein in modulating the toxicity of zinc phosphide, sugg...

BACKGROUND ZIP5 localizes to the baso-lateral membranes of intestinal enterocytes and pancreatic acinar cells and is internalized and degraded coordinately in these cell-types during periods of dietary zinc deficiency. These cell-types are thought to control zinc excretion from the body. The baso-lateral localization and zinc-regulation of ZIP5 in these cells are unique among the 14 members of ...

Lethal effects of zinc sulphate (ZnSO4.H2O), a widespread environmental pollutant was evaluated following exposure at different concentrations of the toxicant to Tilapia species, Oreochromis niloticus based on toxicity index of 96 hrs LC50 values. The obtained results were analyzed by the Finney’s Probit Analysis LC50 Method and 96 hrs LC50 value for Oreochromis niloticus was found to be 72.431...
