Background and objective: Synthesis of zinc oxide nanoparticles (ZnO NPs) with green tea extract (GTE) to form a complex is known to be one of the most multiuse nanoparticles with its application in treatment the toxicity of monosodium glutamate (MSG) on liver, kidney, testis, and pancreas. Therefore, the present study was concerned with the pontifical effect of ZnO NPs / GTE complex on the histological structure of spleen exposed to MSG. Materials and Methods: The toxicity of MSG was evaluated in male albino rats using two dosages (low, 6.0 and high, 17.5 mg/kg). The albino rats were taken for the experiment and randomly assigned into six groups; control, ZnO NPs, MSG-LD, MSG-HD, ZnO NPs / GTE + MSG-LD, and ZnO NPs / GTE + MSG-HD. The animals were decapitated after 30 days of exposure and spleens were dissected out and processed for the histological examination by light microscope. Results: The result revealed that MSG causes shrinkage in the white pulp nodule with increasing the area of the white pulp and degeneration of red pulp as compared to the control. The changes were more prominent in the rats treated with the higher dosage of MSG. The finding suggests that MSG may effect on adhesion of splenocytes and degeneration of red pulp in the rat leading to the reduced immunogenic response. Conclusions: The data could be demonstrated the effect of MSG on spleen tissue was a dose-dependent and led to hypertrophy of white pulp of the spleen. The ZnO NPs/GTE complex could provide a protective benefit against MSG-induced splenomegaly through its potent antioxidant properties due to the presence of GTE and reduction of the ZnO. The future study will be a concern on the thymus histology as it acts as the center of lymphoid organ. Keywords: Monosodium glutamate, ZnO nanoparticles, Spleen, Histology, Rats

Background: Zinc oxide Nanoparticles (NPs) present irreversible effects on the nervous system, memory, and learning. Objective: The current study aimed to investigate the effects of pentoxifylline on memory impairments, CA1 hippocampal pyramidal cells, and blood serum antioxidant enzymes in male rats treated with zinc oxide NPs. Methods: Male Wistar rats were divided into the control, zinc oxide NPs (1.25 mg/kg), pentoxifylline (50 mg/kg), and pentoxifylline with zinc oxide NPs groups. In all study groups, saline, zinc oxide NPs, and pentoxifylline were intraperitoneally injected 30 minutes before training. In the co-treatment group, pentoxifylline was injected one hour before injecting Zno NPs. After performing the behavioral test, the tested animals’ brains were fixed and the number of healthy neurons in the CA1 region of the hippocampus was counted. In all research groups, malondialdehyde levels, total antioxidant power, superoxide dismutase levels, and glutathione peroxidase in blood serum were measured. Results: Zinc oxide nanoparticles decreased memory and the number of healthy neurons in the CA1 region of the hippocampus and increased oxidative stress in blood serum, compared to the controls. In the co-treatment group, using pentoxifylline improved the above-mentioned factors and reached the level of the control group. Pentoxifylline alone presented no significant effect on the aforementioned characteristics, compared to the control group. Conclusion: ZnO NPs may decrease memory retrieval and cause cell death in the pyramidal neurons of the CA1 region of the hippocampus by increasing oxidative stress. Pentoxifylline, as a potent antioxidant, can prevent the harmful effects of ZnO NPs.

The Impact

Nanoparticles are widely applied in all aspects of modern life because of their unique features such as small size and high surface area. Several types of research have been carried out to discover the feasible detrimental impacts of Nano-particles on human reproduction. The purpose of this study was to examine the impact of zinc oxide nanoparticles in mature male rats through examining LH, FSH, and testosterone sex hormones. Therefore, 30 Naked Mole-Rat Initiative (NMRI) rats were divided into 5 groups. Different doses of zinc oxide nanoparticles (250, 500 and 700 mg.kg-1) were intra peritoneally injected to animals only once. Then, the serum level of luteinizing hormone (LH), Follicle Stimulating Hormone (FSH), and testosterone hormones were measured using Enzyme-Linked Immunosorbent Assay (ELISA) method after 21 days. The results were analyzed by ANOVA and Tukey tests. The results indicated that zinc oxide nanoparticles doses caused a significant increase in FSH and testosterone level of blood (Respectively) in 250 and 700mg.kg-1 in comparison with the control group. Moreover, this research illustrated that zinc oxide nanoparticle can cause a dose-related increase in Testosterone and FSH hormones levels while causing no significant change in LH hormone level.
