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 (ZnO NPs) are increasingly utilized in both industrial and medical applications. Therefore, the study was aimed to investigate the effect of green nanoparticle complex (green tea extract/zinc oxide nanoparticles complex, GTE/ZnO NPs) on oxidative stress induced by monosodium glutamate (MSG) on the liver of rats. Methods: Wistar male rats (n=64) weighing between 200-250 g were divided randomly into eight groups: control group was given physiological saline (1 mg/kg), two groups were treated with two different doses of MSG (MSG-LD, MSG-HD; 6 and 17.5 mg/Kg, respectively), GTE was given 1 mg/mL, 5th group was treated with ZnO NPs and 6th group was treated with GTE/ZnO NPs complex while, 7th and 8th groups were treated with MSG-LD + GTE/ZnO NPs complex and MSG-HD + GTE/ZnO NPs complex, respectively. All substances were given orally for 30 consecutive days. At the end of the study, the liver was homogenized for measurement of the oxidative stress status and anti-inflammatory biomarkers as well as histological and transmission alternations. Results: Results showed that the antioxidant enzymes activity and glutathione level were significantly decreased in MSG groups than control in a dose-dependent manner. Conversely, the malondialdehyde and inflammatory cytokines levels were significantly increased in MSG groups than the control group. The liver indicated no evidence of alteration in oxidative status, anti-inflammatory and morphological parameters in GTE, ZnO NPs and GTE/ZnO NPs complex groups. Conclusion: In conclusion, MSG at both doses caused oxidative stress and inflammation on liver after 28 days of exposure that supported histological analysis and transmission view of hepatic parenchyma. GTE/ZnO NPs act as partial hepato-protective against MSG.

Monosodium glutamate (MSG) is used worldwide as a food additive, the survey has disclosed some of MSG's deleterious effects on various organs and tissues of rats. This research was achieved to determine the impact of MSG on the albino rats' antioxidant and histology of cardiac tissue. 48 male rats were divided into six groups of eight rats each. Group one used for monitoring and normal saline, whereas rats of group two were given the lower dosage of MSG 6 mg/Kg, rats in group three received 17.5 m/kg body weight of MSG, while rats in group four were given 10 mg/kg body weight of zinc oxide nanoparticles /green tea extract (ZnO NPs/GTE) complex, the fifth and sixth groups were treated with the lower and the higher doses of MSG with ZnO NP/GTE complex for 30 days. Each animal was sacrificed at the end of the treatment period and the heart was thoroughly separated, determining the antioxidant parameter and the histopathological changes. MSG administration to the rats has shown a substantial rise in peroxidation of cardiac heart tissue, decline in the activities of catalase, superoxide dismutase, and glutathione peroxidase beside the decrease in the glutathione level as compared to those in the control animals. The treatment the induced-rats with MSG using complex showed some degree of recovery by a reduction in LPO of the heart and enhancement of antioxidant enzymes. The findings suggested that the intrinsic antioxidant of the heart tissue can significantly be alternated with the use of MSG in a dose-dependent manner and these changes could be improved by using the green ZnO NPs complex. This complex acts as a factor to decrease the histological damage that could be happening by the induction of MSG.

Background and Objective: This study was designed to estimate the long-term effects of zinc oxide nanoparticles/green tea (ZnONPs/GTE) complex against monosodium glutamate (MSG). The antioxidant/oxidative status, testosterone levels, DNA damage, and histopathological changes of testis were evaluated. Methods: The rats were divided into eight groups that were treated as follows: saline, the lower dosage of MSG (6.0 mg/kg), the higher dosage of MSG (17.5 mg/Kg), GTE, ZnONPs, ZnONPs/GTE and the last two groups were treated with the lower dosage of MSG or the higher dosage of MSG with ZnONPs/GTE complex. The data showed minimal toxicity in testicular tissue after the administration of ZnONPs. Results: The MSG treatment in the adult male rats reduced testosterone levels and disrupted testicular histology, which revealed dose-dependence of MSG. Also, ZnONPs induced testicular dysfunction through the interference of antioxidant/oxidant balance and suppression of testosterone levels as well as induction of cellular damage of testis. The combination of ZnONPs with GTE complex significantly protects against MSG or ZnONPs toxicity by decreasing the DNA damage, oxidative stress, and enhancement of antioxidant as well as histological structure of testis. Conclusion: We could recommend using ZnONPs/GTE complex to reduce the toxicity of ZnONPs and MSG on the testis at the cellular and oxidative stress levels.

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.

Background Monosodium glutamate (MSG) is used extensively as a food additive in the diets of many countries around the world. Aim of the study Our aim was to determine the effects of green zinc oxide nanoparticles on MSG-induced oxidative damage, neurotransmitter changes, and histopathological alternation in the cerebral cortexes of rats. Methods MSG was administered orally at two doses of 6 and 17.5 mg/kg body weight. The higher dose was associated with a significant decline in the activities of superoxide dismutase, catalase, and glutathione peroxidase, as well as the levels of brain-derived neurotrophic factor (BDNF) and glutathione (GSH) in the cerebral cortex of rats. Results The administration of zinc oxide nanoparticles/green tea extract (ZnO NPs/GTE) to 17.5 mg/kg MSG-treated rats was associated with significant improvements in all parameters previously shown to be altered by MSG. The higher dose of MSG induced significant histopathological variation in brain tissue. Co-treatment of rats with ZnO NPs/GTE and MSG-HD inhibited the reduction of neurotransmitters and acetylcholinesterase by MSG. Conclusions ZnO NPs/GTE have the potential to protect against oxidative stress and neuronal necrosis induced by MSG-HD. ZnO NPs/GTE conferred a greater benefit than the control treatment or ZnO NPs or GTE administered separately.

Positive Effects

AbstractZinc oxide nanoparticles (ZnO NPs) demonstrate potential positive effects on reproduction. However, their protective role against the reproductive toxicity pollutants has not yet been adequately studied at the molecular level. This study was designed to assess this objective using Benzo[α]pyrene B[a]P as reproductive toxic agent . Forty-eight mature male rats were randomly distributed into six groups: Group1 (negative control); Groups 2 and 3 (positive control I and II, wherein the animals were treated with 10 and 30 mg ZnO NPs/kg BW, respectively); Group 4 (B[a]P group; treated with 150 mg B[a]P/kg BW); and Groups 5 and 6 (subjected to B[a]P treatment co-administered with different concentrations of ZnO NPs). We investigated oxidative stress biomarkers; cholesterol side-chain cleavage enzyme (CYP11A1), steroidogenic acute regulatory protein (StAR), and 3β-hydroxysteroid dehydrogenase (3β-HSD) gene expression; testosterone levels; and histopathology of the liver, kidney, and testicles. The B[a]P-treated group showed significant deterioration in all reproductive parameters and displayed induced oxidative stress. ZnO NPs remarkably reduced oxidative stress, effectively upregulated the mRNA levels of CY11A1, StAR, and 3β-HSD, and improved the histological pictures in the examined organs. At their investigated doses and given their NPs properties, ZnO NPs demonstrated a marked ameliorative effect against the reproductive toxic effects of B[a]P. Further studies are needed to thoroughly investigate the molecular mechanisms of ZnO NPs.
