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.

The aim of this study was to investigate the possible protective role of caffeic acid phenethyl ester on testicular toxicity of methotrexate in rats. Nineteen male rats were divided into three groups as follows: group I, control; group II, methotrexate-treated; group III, methotrexate + caffeic acid phenethyl ester-treated. In the second day of experiment, a single dose of methotrexate was intraperitoneally administered to groups II and III, although a daily single dose of caffeic acid phenethyl ester was intraperitoneally administered to group III for 7 days. At the end of the experiment, the testes of the animals were removed and weighed. In the tissue, the level of lipid peroxidation as malondialdehyde and activities of superoxide dismutase were higher in the methotrexate group than in the control group. Lipid peroxidation levels and superoxide dismutase activities were decreased in caffeic acid phenethyl ester + methotrexate group compared with methotrexate group. The activities of catalase in the methotrexate group decreased insignificantly although its activities were significantly increased by caffeic acid phenethyl ester administration. The activity of glutathione peroxidase did not change in the groups. There was significant difference in body weight between control and methotrexate-induced groups. In conclusion, the administration of methotrexate causes elevation of oxidative stress although treatment with caffeic acid phenethyl ester has protective effects on the oxidative stress in testes.

Statins are a promising new strategy to prevent contrast-induced acute kidney injury (CI-AKI). In this study we compared the ameliorative effect of different statins in a rat model of CI-AKI. Sprague-Dawley rats were divided into five groups: control group; CI-AKI group; CI-AKI + rosuvastatin group (10 mg/kg/day); CI-AKI + simvastatin group (80 mg/kg/day); and CI-AKI + atorvastatin group (20 mg/kg/day). CI-AKI was induced by dehydration for 72 hours, followed by furosemide intramuscular injection 20 minutes before low-osmolar contrast media (CM) intravenous injection. Statins were administered by oral gavage once daily for 3 consecutive days before CM injection and once 4 hours after CM injection. Rats were sacrificed 24 hours after CM injection, and renal function, kidney histopathology, nitric oxide (NO) metabolites, and markers of oxidative stress, inflammation, and apoptosis were evaluated. The results showed that atorvastatin and rosuvastatin but not simvastatin ameliorated CM-induced serum creatinine elevation and histopathological alterations. Atorvastatin and rosuvastatin showed similar effectiveness against CM-induced oxidative stress, but simvastatin was less effective. Atorvastatin was most effective against NO system dysfunction and cell apoptosis, whereas rosuvastatin was most effective against inflammation. Our findings indicate that statins exhibit differential effects in preventing CI-AKI when given at equivalent lipid-lowering doses.

Abstract: Overtraining accelerates aging due to the excessive production of free radicals that can cause oxidative stress. Banana floret extract contains bioactive compounds with antioxidant capacity which can increase the body's defence to deal with the oxidative stress by increasing the level of superoxide dismutase (SOD). This study was aimed to prove that the banana (Musa x paradisiaca) floret extract could prevent the decrease of superoxide dismutase (SOD) levels in overtraining-induced mice (Mus musculus) BALB/c liver. This was a true experimental study with the post-test only control group design. Subjects were 36 male mice (Mus musculus), BALB/c strain, 12 weeks old, weighing 20-22 g, which were divided into two groups with 18 mice each. The control group (P0) was treated with a placebo of 1 ml aquadest and overtrained for 14 days meanwhile the treatment group (P1) was treated with banana (Musa x paradisiaca) floret extract of 400 mg/kgBW/day and overtrained for 14 days. The results showed that after 14-day treatment, the mean SOD level in the liver tissue of the P0 group was 568.82±9.558 U/mg protein whereas in the P1 group was 588.37±10.629 U/mg protein (P < 0.01). The t-independent test showed a t value of -5.804 and a P value of 0.000 which indicated that after treatment, the levels of SOD in liver tissue of both groups were significantly different. Conclusion: Banana (Musa x paradisiaca) floret extract could prevent the decrease of superoxide dismutase (SOD) levels in the liver tissue of overtraining-induced mice (Mus musculus) BALB/c.Keywords: banana floret, SOD, liver, overtrainingAbstrak: Aktivitas fisik berlebih mempercepat penuaan karena meningkatkan produksi radikal bebas yang dapat menyebabkan stres oksidatif.

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 objective of this study was to investigate the molecular mechanism of the histopathological characteristics of liver cirrhosis (LC) complicated with acute kidney injury (AKI) and the signaling pathway of silent information regulator 1 (SIRT1)-peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) during the pathogenesis of LC. 20 healthy male rats with AKI complicated by laparoscopic cholecystectomy were selected and divided randomly into control group (C group), lipopolysaccharide (LPS) group, bile duct ligation (BDL) group, and model group (lipopolysaccharide+BDL) (D group). The indexes of all the rats were determined, including serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), sarcoplasmic enzyme (Scr), and blood urea nitrogen (BUN); the SIRT1 and PGC-1α expressions in renal tissues of rats from each group was detected. Results showed that the AST and ALT levels in BDL group and D group were higher markedly than those before surgery (P < 0.05). The serum levels of Scr and BUN in D group 4 hours after LPS injection increased hugely compared with before injection (P < 0.05). Compared with BDL group, the protein levels of SIRT1 and PGC-1α in renal tissue of group D were decreased sharply (P < 0.05), and the SIRT1 protein expression was positively correlated with PGC-1α (r = 0.836 and P < 0.01). When LC were complicated with AKI, SIRT1 activity was reduced and PGC-1α expression was inhibited. Moreover, SIRT1-PGC-1α signaling pathway played a protective role in pathogenesis of LC complicated with AKI.

Many studies proposed that oxidative stress and apoptosis are key mechanisms in the pathogenesis of contrast-induced acute kidney injury (CI-AKI). Xylose-pyrogallol conjugate (XP) is an original effective antioxidant that showed decent antioxidant and anti-apoptosis effect before. Thus the therapeutic effect and mechanism of XP in preventing CI-AKI in the short and long term were investigated in this research. Renal function and histological grade were evaluated to determine the severity of renal injury. Kidney samples were then collected for the measurement of oxidative stress markers and the detection of apoptosis. Transmission electron microscopy (TEM) and western blot of mitochondrial protein were utilized for the analysis of the mitochondrial conditions. The results demonstrated that the CI-AKI rats caused a significant decrease in renal function accompanied by a remarkable increase in Malondialdehyde (MDA), bax, caspase-3, cytochrome c (Cyt C) level, TdT-mediated dUTP nick end labeling (TUNEL) positive apoptotic cells, and damaged mitochondria, while a decline in antioxidase activities and mitochondrial superoxide dismutase 2 (SOD2) expression compared with the control rats. However, when XP (50 or 100 or 200 mg/kg/day) was given orally for consecutive 7 days before CI-AKI modeling, XP (200 mg/kg) showed a better capability to restore renal dysfunction, histopathological appearance, the level of apoptosis, mitochondrial damage, oxidative stress, and fibrosis generation without interference in computed tomographic imaging. Our study indicated that antioxidant XP played a nephroprotective role probably via antiapoptotic and antioxidant mechanisms. Besides, XP may regulate the mitochondria pathway via decreasing the ratio of bax/bcl-2, inhibiting caspase-3 expression, cytochrome c release, and superoxide dismutase 2 activity. Overall, XP as a high-efficient antioxidant may have the potentials to prevent CI-AKI.

Melatonin (ML) is a potent antioxidant that reduces oxidative stress. This study was designed to examine the protective effect of melatonin on potassium dichromate- (PDC-) induced male reproductive toxicity. Forty rats were divided into five groups: the control group, rats administered PDC orally (10 mg/kg body weight) for eight weeks, rats administered ML intraperitoneally at doses of either 2.5 or 5 mg/kg followed by the administration of PDC, and rats administered 5 mg/kg ML only. The treatment of rats with PDC led to a decrease in the levels of plasma sex hormones, glutathione, superoxide dismutase, catalase, carnitine, sperm count, and motility. Testicular malondialdehyde levels, nitric oxide concentrations, and abnormalities increased significantly in the PDC group. Melatonin administration to the PDC-treated rats reduced the increase of malondialdehyde and restored the activity of antioxidant enzymes (superoxide dismutase and catalase), glutathione, and sex hormone levels. Moreover, ML attenuated PDC-induced increase in levels of tumor necrosis factor-alpha or interleukin-6. ML alleviated histopathological changes and an increase of p53-positive immune reaction due to PDC. Furthermore, ML inhibited PDC-induced decrease in the DNA content of spermatogenic cells. This study proposed that melatonin may be useful in mitigating oxidative stress-induced testicular damage due to potassium dichromate toxicity.

This study explores the protective mechanism of angiotensin (1-7) [Ang-(1-7)] on kidneys by examining its effects on renal histomorphology, inflammatory response, oxidative stress, and NF-κB signaling in mice suffering from sepsis-induced acute kidney injury. A sepsis-induced acute kidney injury mouse model was established by intracervically injecting lipopolysaccharides (LPS group), followed by the administration of Ang-(1-7) [LPS + Ang-(1-7) group]. The serum levels of urea nitrogen, creatinine and cystatin. c were measured with an automatic biochemical analyzer, and changes in proinflammatory cytokines and angiotensin II (Ang II) in the serum and kidneys were quantified by enzyme-linked immunosorbent assays. Changes in oxidative stress indices in the renal cortex were detected by colorimetry. The localization of Ang II in kidneys was examined by immunohistochemistry. Western blotting was used to examine phosphorylated NF-κB-p65 and IκBα levels in kidneys. Compared with the control group, the serum levels of urea nitrogen, creatinine and cystatin. c were increased, whereas the levels of Ang II, TNFα, IL-1β, IL-6, and malondialdehyde (mda) were increased significantly. The levels of Ang II and phosphorylated NF-κB-p65 were elevated in kidneys, whereas the levels of superoxide dismutase (sod), Total antioxidative capacity (TAOC), and inhibitor of NF-κB (IκBα) were reduced in the LPS group (p &lt; 0.05). Pathological damage was also observed in kidneys of LPS-group mice. In Pearson correlation analysis, there was a positive correlation between Ang II and phosphorylated NF-κB-p65 levels, and a negative correlation between Ang II and IκBα levels (p &lt; 0.05). After the application of Ang-(1-7), the levels of urea nitrogen, creatinine, cystatin. c, Ang II, TNFα, IL-1β, IL-6, and mda, as well as the expression of Ang II and phosphorylated NF-κB-p65 in kidneys of LPS + Ang-(1-7)-group mice, were lower than those in kidneys of LPS-group mice, but the levels of sod, TAOC, and IκBα were higher than those of LPS-group mice (p &lt; 0.05). Pathological changes were less severe in mice of the LPS + Ang-(1-7) group. Overall, Ang-(1-7) can decrease the Ang II level, inhibit NF-κB signaling, reduce the inflammatory response, decrease oxidative stress, and mitigate sepsis-associated acute kidney injury.

Clinical application of gentamicin (GM) is well known to be associated with the development of acute kidney injury (AKI). This study was the first to investigate the possible protective effects of D-limonene (D-lim) on AKI following GM administration in rats. 32 rats arranged in four groups ( n = 8 ): (1) the control group received saline intraperitoneally (0.5 ml/day) and orally (0.5 ml/day), (2) the D-lim group received D-lim (100 mg/kg) orally and saline (0.5 ml/day) intraperitoneally, (3) the GM group received GM (100 mg/kg/day) intraperitoneally and saline (0.5 ml/day) orally, and (4) the treated group received intraperitoneal GM (100 mg/kg) and oral D-lim (100 mg/kg). All treatments were performed daily for 12 consecutive days. Results revealed that D-lim ameliorated GM-induced AKI, oxidative stress, mitochondrial apoptosis, and inflammation. D-lim showed nephroprotective effects as reflected by the decrease in serum urea and creatinine and improvement of renal histopathological changes. D-lim alleviated GM-induced oxidative stress by increasing the activities of renal catalase, serum and renal glutathione peroxidase, and renal superoxide dismutase and decreasing renal malondialdehyde and serum nitric oxide levels. Intriguingly, D-lim suppressed mitochondrial apoptosis by considerably downregulating Bax and caspase-3 (Casp-3) mRNA and protein expressions and markedly enhancing Bcl2 mRNA and protein expressions. Furthermore, D-lim significantly decreases GM-induced inflammatory response through downregulation of NF-κB, IL-6, and TNF-α mRNA and/or protein expressions and decrease in renal myeloperoxidase activity. Finally, D-lim remarkably downregulated PCNA protein expression in the treated group compared with the GM group. In brief, this study showed that D-lim alleviated AKI following GM administration in rats, partially through its antioxidant, anti-inflammatory, and antiapoptotic activities as well as downregulation of PCNA expression.
