Protective Effects of Dietary Spirulina platensis against Cadmium-Induced Oxidative Stress in Gills of Rainbow Trout

Protective Effects of Vitamin C and Chitosan against Cadmium-Induced Oxidative Stress in the Liver of Common Carp (Cyprinuscarpio)

Background: Cadmium (Cd) intoxication can cause oxidative stress and involve the antioxi-dant defense system in hepatocytes. Administration of vitamin C, chitosan, or a combination of both may prevent Cd-induced oxidative damage. Methods:Cyprinus carpio were distributed into six groups. The control group received normal feed (Group I). Group II was exposed to 0.2 mg.L-1 cadmium chloride. Gr...

Cadmium inhibition of Ca2+ uptake in rainbow trout gills

Cadmium inhibition of Ca2+ uptake in rainbow trout gills.

The effects of cadmium (Cd2+) on calcium (Ca2+) transport in the gills of rainbow trout (Salmo gairdneri) were studied. The gill epithelium of freshwater fish represents a model for a Ca2+-transporting tight epithelium. Unidirectional Ca2+ fluxes in the gills were estimated in an isolated saline-perfused head preparation. Ca2+ influx was not affected when up to 10 microM Cd were added to the ve...

Protective Effects of Crocin against Cisplatin-Induced Acute Renal Failure and Oxidative Stress in Rats

Background. The major side effect of cisplatin, used in some tumours, is nephrotoxicity. Reactive oxygen species and oxidative damage are the most important factors in cisplatin-induced acute renal failure. The main purpose of this study is to investigate the protective effects of crocin against cisplatin-induced acute renal failure and oxidative stress in rat. Methods. In this study, animal...

Protective effects of erythropoietin against cuprizone-induced oxidative stress and demyelination in the mouse corpus callosum

Objective(s): Increasing evidence in both experimental and clinical studies suggests that oxidative stress plays a major role in the pathogenesis of multiple sclerosis. The aim of the present work is to investigate the protective effects of erythropoietin against cuprizone-induced oxidative stress. Materials and Methods: Adult male C57BL/6J mice were fed a chow containing 0.2 % cuprizone for 6 ...

Physiological effects of dietary cadmium acclimation and waterborne cadmium challenge in rainbow trout: respiratory, ionoregulatory, and stress parameters.

A suite of respiratory, acid-base, ionoregulatory, hematological, and stress parameters were examined in adult rainbow trout (Oncorhynchus mykiss) after chronic exposure to a sublethal level of dietary Cd (500 mg/kg diet) for 45 days and during a subsequent challenge to waterborne Cd (10 microg/L) for 72 h. Blood sampling via an indwelling arterial catheter revealed that dietary Cd had no major...
