Cadmium (Cd) is a highly toxic environmental and industrial cumulative pollutant that affects many organs, especially the liver. The present study was designed to evaluate the antioxidant effect of green tea on cadmium-induced hepatic dysfunction and oxidative stress in rats. Adult male Wistar rats were administered cadmium by injection of 20 micromoles/kg bw/every 3 days for six months. This study revealed significant (p < 0.05) liver dysfunction, lipid peroxidation and a decline in antioxidant enzyme activities in the liver of cadmium-treated rats compared to control animals. Compared to control rats, the activities of lactate dehydrogenase (LDH), gammaglutamyl transferase (GGT), acid phosphatase (PAC), phosphatase alkaline (PAL), as well as bilirubin and thiobarbituric acid-reactive substances (TBARs), were significantly (p < 0.05) increased in Cd-treated rats. Moreover, antioxidant enzyme activities, such as superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase, were significantly (p < 0.05) decreased in the liver of cadmium-treated rats. The oral administration of 5% aqueous green tea extract, along with cadmium treatment for six months, caused a significant (p < 0.05) improvement in cadmium-induced toxicity by significantly decreasing (p < 0.05) the activities of enzymatic markers of liver dysfunction (LDH, GGT, PAC, PAL activities, as well as the bilirubin rate). Indeed, green tea extract significantly increased (p < 0.05) antioxidant enzymatic activities (SOD, Catalase, GPX) in rat liver, compared to those given cadmium alone. Thus, the oral administration of green tea, along with cadmium significantly (p < 0.05) improves cadmium-induced liver dysfunction and stress oxidant in rats' liver.

The sunflower (Helianthus annuus L. cv. PAC 36) seedlings were inoculated with plant growth promoting rhizobacteria (PGPR), viz. Azotobacter chroococcum (A+), Bacillus polymyxa (B+), separately and in combination of the two (AB+). Relative water content and seedling growth were maximum in AB+ seedlings under control. Water stress significantly decreased the RWC, growth and dry mass of non-inoculated seedlings. However, inoculated seedlings maintained higher growth even under water stress. Pigments and protein contents decreased under water stress, but higher amount of the same was observed in stressed AB+ seedlings. Enhanced activity of nitrate reductase was recorded in AB+ seedlings with maximum in control. Water stress significantly decreased the nitrate reductase activity. A significant increase in the activity of superoxide dismutase (SOD) in leaves was recorded under water stress except in B+ with maximum increase in non-inoculated seedlings. Catalase (CAT) activity decreased in stressed non-inoculated seedlings while increased in the leaves of A+ and AB+ seedlings. Almost similar trends were recorded for both leaves and cotyledons. PGPR improved the water status in stressed seedlings and thereby physiological and biochemical parameters and thus ameliorated the severe effects of water stress.
