The Impact

This study aimed to describe the protective efficacy of Moringa oleifera ethanolic extract (MOEE) against the impact of cobalt chloride (CoCl2) exposure on the rat’s kidney. Fifty male rats were assigned to five equal groups: a control group, a MOEE-administered group (400 mg/kg body weight (bw), daily via gastric tube), a CoCl2-intoxicated group (300 mg/L, daily in drinking water), a protective group, and a therapeutic co-administered group that received MOEE prior to or following and concurrently with CoCl2, respectively. The antioxidant status indices (superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH)), oxidative stress markers (hydrogen peroxide (H2O2), 8-hydroxy-2-deoxyguanosine (8-OHdG), and malondialdehyde (MDA)), and inflammatory response markers (nitric oxide (NO), tumor necrosis factor (TNF-α), myeloperoxidase (MPO), and C-reactive protein (CRP)) were evaluated. The expression profiles of pro-inflammatory cytokines (nuclear factor-kappa B (NF-kB) and interleukin-6 (IL-6)) were also measured by real-time quantitative polymerase chain reaction (qRT-PCR). The results showed that CoCl2 exposure was associated with significant elevations of oxidative stress and inflammatory indices with reductions in the endogenous tissue antioxidants’ concentrations. Moreover, CoCl2 enhanced the activity of the NF-κB inflammatory-signaling pathway that plays a role in the associated inflammation of the kidney. MOEE ameliorated CoCl2-induced renal oxidative damage and inflammatory injury with the suppression of the mRNA expression pattern of pro-inflammatory cytokine-encoding genes. MOEE is more effective when it is administered with CoCl2 exposure as a prophylactic regimen. In conclusion, MOEE administration exhibited protective effects in counteracting CoCl2-induced renal injury in rats.

There have been major concerns that the nephrotoxicity of commercial formulations of Roundup herbicide is due to the active ingredient glyphosate. We therefore investigated and compared the mechanisms underlining the nephrotoxicity of Roundup herbicide and glyphosate alone in rat. Fifty-six adult male rats randomized into 7 groups of 8 rats per group were exposed to Roundup formulation and glyphosate alone daily by gavage at 3.6, 50.4, and 248.4 mg/kg body weight (bw) of glyphosate concentrations for 12 weeks with distilled water administered to the control group. Kidney biomarker (serum urea and creatinine, plasma cystatin-C, and neutrophil gelatinase-associated lipocalin), oxidative stress indices in the kidney tissue, activities of kidney membrane-bound enzymes (Mg-adenosine triphosphatase [ATPase], Ca-ATPase, Na/K-ATPase, and total ATPase), and histopathological changes in the kidney were monitored. Glyphosate concentration in the kidney was quantified by high-performance liquid chromatography with ultraviolet detection. Significant ( P < 0.05) alterations in the levels of the kidney biomarker, oxidative stress markers, and membrane-bound enzymes were observed in the rats exposed to Roundup compared to the rats exposed to glyphosate alone. Rats exposed to Roundup accumulated more glyphosate residue in their kidney tissue. Severe histopathological lesions were only seen in the kidneys of rats exposed to Roundup. The nephrotoxicity observed cannot be due to the active ingredient in the Roundup formulation, as glyphosate alone has virtually no effect on the renal function of the exposed animals. Therefore, the general claim attributing nephrotoxicity of a glyphosate-based herbicide to its active ingredient should be discouraged.

The Impact

It is common for food to be made more palatable through the use of the flavour enhancer monosodium glutamate, also known as vetsin powder. The purpose of the study described in this paper was to explore how vetsin-induced hepatic toxicity, DNA fragmentation, damage, and oxidative stress modifications could be mitigated with moringa leaf extract (MLE). To that end, 40 male rats were separated into four groups: normal control, positive control or MLE, vetsin, and vetsin combined with MLE. Results indicated that, compared to the control group, the levels of serum alanine aminotransferase (ALT), aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), liver malondialdehyde (MDA), DNA damage, injury, PCNA, and P53 expressions were significantly enhanced by the administration of vetsin (P<0.05). However, the vetsin group had significantly reduced levels of albumin, globulin, total protein, liver glutathione (GSH), superoxide dismutase enzyme (SOD), catalase, and glutathione S-transferase (GST) enzyme activities (P<0.05) by comparison to control. Meanwhile, modifications in liver functions, oxidative stress, DNA damage, liver injury, and PCNA expression were alleviated when vetsin was administered alongside MLE. The authors conclude that vetsin may have many side effects and that MLE can ameliorate biochemical changes, oxidative stress, hepatic injury, PCNA, and P53 alterations induced by vetsin administration.

Sepsis Score

Sepsis is one of the leading causes contributing to the incidence of acute kidney injury (AKI). Oxidative stress can be used as the main approach against sepsis-induced AKI. One of the primary antioxidants that plays a role in warding off oxidative stress is superoxide dismutase (SOD). This research aimed to observe the effect of antioxidant SOD in inhibiting sepsis in AKI based on kidney tissue histopathology. The research method was an experimental laboratory with a post-test-only control group design. Twenty-five adult male rats aged 12–16 weeks, weighing between 200 and 250 g, were randomly divided into five groups: Group I, as a positive control, where rats were injected with lipopolysaccharides (LPS); Group II, as a negative control; Group III, as treatment 1, where rats were injected with LPS and administered orally with SOD (Glisodin®) 250 IU daily; Group IV, as treatment 2, where rats were injected with LPS and administered orally with SOD (Glisodin®) 500 IU daily; and Group V, as treatment 2, where rats were injected with LPS and administered orally with SOD (Glisodin®) 1000 IU daily. Rats were administered with SOD (Glisodin®) by oral gavage with a flexible feeding tube for 16 weeks, given once daily in the morning, and then injected with LPS of 10 mg/kg body weight. Glisodin SOD had a significant effect on murine sepsis score (MSS). MSS influenced the tubular injury score linearly. We conclude that the optimal dose of SOD at 1000 IU for inhibiting sepsis-induced AKI incidence is compared to SOD at a dose of 250 and 500 IU. The antioxidant effect of SOD can prevent sepsis-induced AKI with oxidative stress events.

Objective: This experimental study was conducted to elucidate the possible protective/therapeutic effects of quercetin against methotrexate (Mtx)-induced kidney toxicity with biochemical and histopathological studies. Methods: Twenty-four adult male rats were randomly divided into four groups, as follows: control group (saline intraperitoneally (i.p.), 9 days), Mtx group (20 mg/kg i.p., single dose), Mtx + quercetin group (50 mg/kg quercetin was orally administered 2 days before and 6 days after Mtx administration) and only quercetin group (50 mg/kg oral, 9 days). Structural changes were evaluated by hematoxylin–eosin and periodic acid–Schiff stainings. Apoptotic changes were investigated by terminal deoxynucleotidyl transferase dUTP nick end labeling assay and caspase-3 antibody. Superoxide dismutase (SOD) and malondialdehyde (MDA) levels were measured in tissue and plasma samples. Results: Mtx compared with the control group, there was significant increase in nephrotoxic tissue damage findings, in addition to apoptotic index (APOI) and caspase-3 expression ( p < 0.05). Mtx + quercetin group revealed significantly lower histopathological damage and APOI and caspase-3 expression decreased when compared to Mtx group. MDA levels were increased in Mtx group compared to others, and by the use of quercetin, this increase was significantly reduced. SOD levels were higher in Mtx group than others. This increase was evaluated as a relative increase arising from oxidative damage caused by Mtx. Conclusion: As a result, Mtx administration may involve oxidative stress by causing structural and functional damage in kidney tissue in rats. Quercetin reduced the Mtx-induced oxidative stress through its antioxidant properties and so quercetin may be promising to alleviate Mtx-induced renal toxicity.

Retinol binding protein 4 (RBP4) is a transporter of vitamin A that is secreted mainly by hepatocytes and adipocytes. It affects diverse pathophysiological processes, such as obesity, insulin resistance, and cardiovascular diseases. MicroRNAs (miRNAs) have been reported to play indispensable roles in regulating various developmental processes via the post-transcriptional repression of target genes in mammals. However, the functional link between RBP4 and changes in miRNA expression in porcine granulosa cells (GCs) remains to be investigated. To examine how increased expression of RBP4 affects miRNA expression, porcine GCs were infected with RBP4-targeted lentivirus for 72 h, and whole-genome miRNA profiling (miRNA sequencing) was performed. The sequencing data were validated using real-time quantitative polymerase chain reaction (RT-qPCR) analysis. As a result, we obtained 2783 known and 776 novel miRNAs. In the experimental group, 10 and seven miRNAs were significantly downregulated and upregulated, respectively, compared with the control group. Ontology analysis of the biological processes of these miRNAs indicated their involvement in a variety of biological functions. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses indicated that these miRNAs were involved mainly in the chemokine signaling pathway, peroxisome proliferators-activated receptors (PPAR) signaling pathway, insulin resistance pathway, nuclear factor-kappa B(NF-kappa B) signaling pathway, and steroid hormone biosynthesis. Our results indicate that RBP4 can regulate the expression of miRNAs in porcine GCs, with consequent physiological effects. In summary, this study profiling miRNA expression in RBP4-overexpressing porcine GCs provides an important reference point for future studies on the regulatory roles of miRNAs in the porcine reproductive system.

Abstract: Objective: To investigate the effect of tripterine on Notch signaling pathway in renal tissue of IgA nephropathy rats. Methods: SD male rats were divided into the control group, IgAN nephropathy model group, benazepril group, 1mg/kg/d tripterine intervention group and 10mg/kg/d tripterine intervention group according to the random number table method, with 10 rats in each group. The urinary sediment and 24-hour urinary protein quantity were detected by conventional methods. The expressions of Notch1, Jagged1, Hes1 and Hey1 in renal tissue of rats were detected by real-time fluorescent quantitative PCR. Results: IgA nephropathy model was successfully established. The hematuria and proteinuria in model group were higher than those of control group (P<0.05). The expressions of Notch1, Jagged1, Hes1 and hey1 in kidney tissue of IgA nephropathy rats were significantly increased (P<0.05). Compared with the model group, hematuria and proteinuria in tripterine intervention group were alleviated. The expressions of Notch1, Jagged1, Hes1 and Hey1 in rat renal tissue were decreased (P<0.05). Moreover, the expressions of Notch1, Jagged1, Hes1 and Hey1 in renal tissue of rats in 10mg/kg/d tripterine intervention group were decreased (P<0.05). Conclusion: Tripterine can decrease the levels of hematuria and proteinuria in IgA nephropathy rats. The expression of Notch signaling pathway in IgA nephropathy rats is increased by the down-regulation of tripterine, suggesting that tripterine has a certain therapeutic effect on IgA nephropathy rat. And its role may be realized through this signal pathway so as to provide the new mentality for the diagnosis and treatment of IgA nephropathy.

Abstract Tramadol is a synthetic opioid analgesic used for moderate-to-severe pain structurally related to codeine and morphine, where their analgesic mechanism is a result of opioid and non-opioid mechanisms. This study was designed to evaluate the effects of Moringa oleifera leaves extract (MLE) on tramadol-induced testicular toxicity, sperm changes, testicular damage, and oxidative stress in male rats. Forty male albino rats were divided into four groups and treated for 4 weeks (group 1, as control; group 2, MLE; group 3, tramadol; group 4, MLE + tramadol). The relative body weight, relative testes weight, serum total testosterone, luteinizing hormone, follicle-stimulating hormone, sperm counts, vitality, total sperm motility, catalase, and superoxide dismutase activities were significantly decreased in tramadol-treated group when compared with the control group. In contrast, sperm abnormality, immotile sperm percent, testicular injury, and TBARS concentration in testes were significantly increased in the tramadol-treated group. In addition, histopathological examination for the tramadol-treated group has shown incomplete spermatogenesis, moderate degeneration in some seminiferous tubules with a significant decrease in the number of spermatogenic cells and depletion of Leydig cells. The administration of MLE with tramadol ameliorates the testicular toxicity, injury, sperm count, abnormalities, and oxidative stress induced by tramadol.

Introduction: Taking anabolic steroids can affect the state of oxidative stress in different tissues of the body such as kidneys. This study aimed to examine the effect of 8 weeks of resistance training with testosterone enanthate consumption on tissue oxidation indicators in male rats. Methods: In the current experimental study, 18 rats with an average weight of 250 ± 50 g were divided into 3 groups of 6 animals including: (1) control, (2) training, and (3) training + testosterone. Rats in the training and training + testosterone groups underwent resistance training for 8 weeks and 5 sessions per week. Also, rats in the training + testosterone group received 20 mg/kg of testosterone enanthate by intramuscular injection 3 days a week. The resistance training protocol consisted of climbing a 1-meter ladder 5 days a week (4 sets of 6 with a rest interval of 60 to 90 seconds) in which the weights were 60% of the rats’ body weights in the first week, and 20% of the body weight was added to the weights every week. One-way analysis of variance was used to analyze the research findings (P≤0.05). Results: Glutathione peroxidase (GPx) level in the training + testosterone group was significantly lower than the control group (P=0.007); however, there were no significant differences in malonaldehyde (MDA) (P=0.64) and superoxide dismutase (SOD) (P=0.29) levels between the research groups. Conclusion: It seems that testosterone consumption can be effective in increasing oxidative stress factors in the kidney tissue of resistance-trained rats.
