In vitro susceptibility of duck, chicken, and pig erythrocyte lipids to peroxidation

Abstract

e susceptibility of erythrocyte lipid to in vitro peroxidation as measured by TBARS (thiobarbituric acid-reactive substances) and concentration of reduced glutathione (GSH) in whole blood and erythrocyte suspension before and after incubation with hydrogen peroxide was assessed in ducks, chickens and pigs. A high susceptibility of erythrocytes to peroxidation in vitro was observed in all animals tested, but this susceptibility was of different intensity. Pig erythrocytes exhibited the lowest resistance to oxidative stress in vitro as compared with that in ducks (P < 0.01) and chickens (P < 0.02). A high level of GSH in the erythrocytes of ducks and chickens offers higher resistance to oxidative stress in comparison with that in the pig erythrocytes.

Changes in the oxidative status of dual-purpose hens rearing in the free-range system during cold, thermoneutral and hot period

“…Plasma and erythrocyte levels of tGSH are one of the main indicators of oxidative-reductive processes in the body. Its depletion in the birds is associated with the development of OS(Gradinski-Vrbanac et al 2002). As regards the antioxidant enzymes assessed in this study, an increase in the erythrocyte SOD and GPX activity during the cold and hot periods compared to the thermoneutral period was observed.…”

Delta-ALA-D inhibitory potential and protective action ofSyzygium jambosandSolanum guaraniticumleaf extracts on oxidatively stressed erythrocytes

“…1 The erythrocytes are constantly exposed to oxidative injury, but their metabolic activity is capable of reversing the injury under normal conditions. 2 Erythrocytes are protected by the powerful action of the endogenous antioxidant enzymes present in its membranes and cytoplasmic compartments against the continuous production of free radicals by preventing the production of ROS, reducing the generated molecules, or repairing the damage caused by them. 3 However, following an increase in oxidative stress, irreversible damage to erythrocytes occurs, resulting in their ultimate loss by hemolysis and removal from circulation.…”
