Zinc Toxicity in Rats
The evaluation of the nutritional quality of foods and feeds requires a more definite knowledge of the physiological role of the various micro nutrient inorganic elements in the animal body than is now available. Problems of immediate concern include the effects of one or more of these elements on the utilization of another, for example the effect of traces of arsenic in reducing the toxicity o...
متن کاملZinc Toxicity in Humans
In dealing with zinc’s essentiality/toxicity (Dr. Jekyll and Mr. Hyde) duality, biological systems have developed the homeostatic ability to tightly regulate the zinc levels through a complicated framework for import and export, transport and distribution and sensing of zinc status to ensure that zinc does not participate in toxic reactions. In spite of the thousands of papers that have been pu...

atomic number above 20. These properties are not the world. In India it is cultivated under 83.00 ha of relevant for biological effects, yet the heavy metals land with production of 7.9 lakh metric tonnes. Keeping enclose essential nutrients, beneficial elements and these points in view the present investigation has been elements which, at the present stage of knowledge, are made to study the e...
متن کاملProtection against zinc toxicity by metallothionein and zinc transporter 1.
Cells protect themselves from zinc toxicity by inducing proteins such as metallothionein (MT) that bind it tightly, by sequestering it in organelles, or by exporting it. In this study, the interplay between zinc binding by MT and its efflux by zinc transporter 1 (ZnT1) was examined genetically. Inactivation of the Znt1 gene in baby hamster kidney (BHK) cells that do not express their Mt genes r...
متن کاملModeling zinc toxicity for terrestrial invertebrates.
Acute and chronic ecotoxicity tests with zinc were performed with the earthworm Eisenia fetida, the potworm Enchytraeus albidus, and the springtail Folsomia candida. To assess the influence of the soil type on zinc toxicity for these soil invertebrates, these tests were carried out in a standard artificial soil, a sandy and a loamy field soil. Based on the results of this experimental work and ...
