Human blood monocytes and neutrophils were incubated with an H202-generating system (glucose plus glucose oxidase) in the presence and absence of 2 mM sodium azide. to assess the importance of catalase in the protection of these cells against heavy external oxidative stress (50 nmole H202/mI/min). Before and after these incubations. the cell integrity was determined. as well as the following ce...

Heavy metals are the cause of major abiotic stresses in plants and a principal contributor to environmental pollution in recent decades. This study investigated the effects of exogenous hydrogen sulfide on the ascorbate-glutathione cycle in the leaves of coriander seedlings under copper stress. Results showed that copper stress not only reduced APX and GR activities but also decreased leaf AsA,...

The major aim of this work was to investigate how alcohol-induced oxidative stress in combined chemotherapy changes the metabolic function of the liver in experimental animals. This research was conducted to establish how bromocriptine, haloperidol and azithromycin, applied to the experimental model, affected the antioxidative status of the liver. The following parameters were determined: reduc...
