And Oxidative Stress

Effect of potassium dichromate was studied experimentally in African Catfish (Clarias gariepinus) with and without vitamin E in induced haematoxicity and oxidative stress. Blood samples were collected for haematology and plasma biochemical parameters while gills, liver and kidney samples were collected for evaluation of markers of oxidative stress. Exposure to potassium dichromate led to a significant decrease in PCV, RBC, haemoglobin concentration, MCV, MCH and total WBC when compared with the unexposed     control and those fed with vitamin E-supplemented feed. Nephrotoxicity was also observed as evidenced by increases in plasma creatinine levels. Exposure to potassium dichromate also led to increased oxidative stress as the concentrations of antioxidant endogenous enzymes - GPx, GST and GSH were depleted while potentiating lipid peroxidation and hydroxyl radical generation. The changes in the haematological, biochemical and antioxidant parameters were restored in the fish fed with vitamin E-supplemented feed. The study showed exposure to potassium dichromate to be toxic to African catfish, causing anaemia and kidney damage with free radical generation and depletion of GSH and other antioxidant defence system but the toxic effect can be minimised along with weight gain in fish supplemented by vitamin – E in aquaculture.

Barley Genotypes

The purpose of this paper was to examine the effect of water deficit on membrane injuries, superoxide radical generation and lipid peroxidation in the leaves of two barley genotypes. Six-day-old seedlings of the cv. Aramir and line R567 were used in the experiments. According to our earlier work these genotypes significantly differ in the level of membrane injuries under water deficit conditions. Water stress was applied directly to leaves or to roots. The stress caused considerable membrane injuries in the leaves of all genotypes investigated.The percentage membrane injury was higher in the line R567 than in the cv. Aramir. Water stress imposed on leaves caused higher membrane injuries than water stress imposed on roots. The water stress treatment followed by an oxidative stress in the leaves. Line R567 having noticeably larger membrane injuries also exhibited a higher level of superoxide radical generation than the cv. Aramir. The level of lipid peroxidation increased in the both genotypes under the conditions of water stress imposed on leaves, but not on roots.
