This study which designed to evaluate the inhibitory effect of Ethanolic extract of (Quercusrobur) and Zinc oxide nanoparticles on the growth of one genus of enterobacteriacae (Salmonella). In vitro. For this purpose graduate concentrates for plant extract (50, 100, 200, 400 )mg/ml which prepared and compared with Zinc oxide nanoparticles of different concentration (2, 1, 0.5, 0.25) μg/ml,and examined. The result showed that the studied medicinal plant has antibacterial activity against this bacteria which used. The result showed that the plant has good activity in decrease the growth of this bacteria. The results of the study also showed that the nano-ZnO has very effective antibacterial action against the studied bacteria which was Salmonella,nanoparticles concentrations lead to increasing in the inhibition zones of tested bacterial growth. We also study the effect of three antibiotics Lomefloxacin (LOM), Ciprofloxacin (SIP) and Rifampin (RA) and the result showed,in a comparison within the tested bacteria,Salmonella had a significant inhibition increase in Lomefloxacin ; the ciprofloxacin showed effect on tested bacteria. However,Rifampin does not show any effect on tested bacteria.

Background: Zinc oxide nanoparticles (ZnO NPs) are robustly used biomedicine. Moreover, no study has been conducted to explore the consequence of green synthesis of ZnO NPs with Camellia sinensis (green tea extract, GTE) on kidneys of rats treated with monosodium glutamate (MSG). Methods: Therefore, the objective of the research was designed to explore the possible defensive effect of GTE/ZnO NPs against MSG-induced renal stress investigated at redox and histopathological points. Results: The levels of urea and creatinine increased as the effect of a high dose of MSG, in addition, the myeloperoxidase and xanthine oxidase activates were elevated significantly with the high dose of MSG. The levels of non-enzymatic antioxidants (uric acid, glutathione, and thiol) were decreased sharply in MSG-treated rats as compared to the normal group. Conclusion: The data displayed that GTE/ZnO NPs reduced the effects of MSG significantly by reduction of the level peroxidation and enhancement intracellular antioxidant. These biochemical findings were supported by histopathology evaluation, which showed minor morphological changes in the kidneys of rats.
