Oxidative Stress in Lead and Cadmium Toxicity and Its Amelioration
Oxidative stress has been implicated to play a role, at least in part, in pathogenesis of many disease conditions and toxicities in animals. Overproduction of reactive oxygen species and free radicals beyond the cells intrinsic capacity to neutralize following xenobiotics exposure leads to a state of oxidative stress and resultant damages of lipids, protein, and DNA. Lead and cadmium are the co...

متن کاملResponse of Ultimobranchial and Parathyroid Glands of the Indian Skipper Frog, Euphlyctis cyanophlyctis to Cadmium Toxicity
Background: Cadmium toxicity has been shown in aquatic animals but the effect on frog’s endocrine glands is not known. We investigated the effects of cadmium on ultimobranchial and parathyroid glands of Indian skipper frog, Euphlyctis cyanophlyctis. Methods: Frogs were exposed to cadmium chloride for short and long terms and sacrificed after 24, 48, 72 or 96 h (short-term) and after 5, 10, 1...
متن کاملBiochemical and Cellular Response of Catharanthus roseus Callus Cells to Cadmium Toxicity
Catharanthus roseus is a medicinal and ornamental plant with growing attention toward its economical value. Cell suspension from C. roseus were treated with 0 to 60mM of cadmium nitrate for 1, 3 and 6 days, then cell viability was determined using trypan blue and MTT assay. Cell morphology was investigated using 0, 10, 30 and 50 mM of cadmium nitrate as selected dose for 3 days. Callus of C.ros...
متن کاملLiver and Cadmium Toxicity
Cadmium (Cd) is an important industrial and environmental toxicant with many industrial applications. Cd emissions to the atmospheric, aquatic, and terrestrial environment have increased during the last century. Since Cd is not degraded in the environment, the risk of human exposure is constantly increased due to Cd also enters to the food chain [1]. Humans are generally exposed to Cd by two ma...
