Abstract. Eteng OE, Moses CA, Enobong J, Akamo AJ, Akinloye DI, Ugbaja RN, Akinloye OA. 2020. Protective effects of Curcuma longa rhizomes ethyl acetate extract against alcohol induced oxidative stress and nephrotoxicity in female Wistar rats. Biofarmasi J Nat Prod Biochem 21: 5-12. This study aimed to evaluate the protective effect of Curcuma longa Linn. (syn. Curcuma domestica Val.) rhizomes ethyl acetate extract (CLREAE) facing alcohol-induced oxidative stress and nephrotoxicity. Thirty female (30) Wistar rats were categorized randomly into six groups. Groups 1, 2, 3, 4, 5 and 6 were treated with normal saline; 20% ethanol; 100 mg of CLREAE + 20% ethanol; 200 mg of CLREAE + 20%; 350 mg of CLREAE + 20% ethanol and 350 mg of CLREAE respectively for 14 days. A significant (p<0.05) decrease in the SOD, CAT and GPx activities and GSH concentration of rat treated with only 20% ethanol were found when compared to the normal control group, whereas a significant (P<0.05) increase in the groups pretreated with different doses of the CLREAE were also found when compared to groups with only 20% ethanol treatment. Thus, comparing to the normal control group, treatment with the CLREAE fetched a significant (p<0.05) decrease in the renal biomarkers (creatinine and urea).  Whilst, comparing to the groups with 20% methanol treatment, a significant (p<0.05) increase happened in the groups pretreated with different doses of the CLREAE. There was a significant (p<0.05) decrease on Kidney MDA level in rats pretreated with different doses of CLREAE compared with the normal control. It was shown in the results of the histology that there was a physiologic recovery in the kidney tissues as groups were treated with different doses of the CLREAE. Evidenced by reduced necrosis of tubular and glomerular epithelial, the signs of protection against toxicity were found on the rats. The study suggested that through in vivo free radical scavenging ability, the CLREAE has protective effects against alcohol-induced oxidative stress and nephrotoxicity in female Wistar rats.

Doxorubicin-induced cardiotoxicity is the leading cause of morbidity and mortality among cancer survivors. The present study was aimed to investigate the cardioprotective potential of methyl gallate; an active polyphenolic nutraceutical, against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats (150–200 g) were divided into four groups (n = 6) which consist of normal control (group I), doxorubicin control (group II), test-A (group III), and test-B (group IV). Group III and group IV animals were prophylactically treated with methyl gallate 150 mg/kg/day and 300 mg/kg/day orally, respectively, for seven days. Doxorubicin (25 mg/kg; single dose) was administered through an intraperitoneal route to group II, III, and IV animals on the seventh day to induce acute cardiotoxicity. On the 8th day, besides ECG analysis, serum CK, CK-MB, LDH, AST, MDA, and GSH were assayed. Following gross examination of isolated hearts, histopathological evaluation was performed by light microscopy. A significant ( p  < 0.05) cardiac injury, as well as oxidative stress, was observed in doxorubicin control rats in comparison to normal control rats. Methyl gallate at both the doses significantly ( p  < 0.05) reduced doxorubicin-induced ECG changes, dyslipidaemia, and elevation of CK, CK-MB, LDH, AST, MDA and increased GSH level. Methyl gallate reversed the doxorubicin-induced histopathological changes in the heart. The present study revealed that methyl gallate exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats by suppressing oxidative stress. Our study opens the perspective to clinical studies for consideration of methyl gallate as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.

AbstractBackgroundHypertension is a silent killer with no obvious signs and symptoms; thus, it is crucial to prevent its development. Oxidative stress and hyperlipidemia are associated risk factors for developing hypertension. This study aimed at investigating the role of a crude extract of Senecio serratuloides in preventing the development of hypertension, oxidative stress and hyperlipidemia in a rat model of nitric oxide deficiency.MethodsFemale Wistar rats were co-treated with Nω-Nitro L-arginine methyl ester (L-NAME) (40 mg/kg) and the hydroethanolic extract of S. Serratuloides (HESS150 or HESS300 mg/kg) for 4 weeks. Twenty-hour urine samples were collected weekly during the study. At the end of the study serum, heart and kidneys were harvested for biochemical and histopathological analysis.ResultsThe higher dose (300 mg/kg) of the extract was more effective in preventing increase in systolic (p<0.001) and diastolic (p<0.05) blood pressure. At the end of the treatment period HESS300 treated rats had significantly (p<0.01) higher concentration of creatinine (91.24 ± 6 mg/dL) in urine and significantly (6.36 ± 0.4 mg/24 h; 0.001) lower proteinuria compared to L-NAME control rats (55.75 ± 8 mg/dL and 18.92 ± 2 mg/24 h, respectively). Creatinine clearance and glomerular filtration rate were lower in the L-NAME control group compared to all treatment groups. HESS300 prevented L-NAME-induced decrease in serum angiotensin II concentration, significantly decreased malondialdehyde concentration in serum (p<0.05) and kidneys (p<0.001). It also significantly (p<0.001) decreased low-density lipoprotein concentration while increasing the concentration of high-density lipoprotein cholesterol. It showed cardio- and reno-protective effects and significantly (p<0.01) prevented collagen deposition in these target organs.ConclusionThese findings demonstrate the potential of S. Serratuloides in protecting rats from developing hypertension, hyperlipidemia and oxidative stress.

Abstract Objectives We investigated the effect of apelin-13 on the cellular model of AD, amyloid-β (Aβ) treated SH-SY5Y cells in rats. Methods The SH-SY5Y cells were pretreated with different doses of apelin-13 (1, 2.5, 5, and 10 μg/mL), half an hour before adding 50% Aβ treatment. After 24 h, cells were evaluated for survival, oxidative stress, mitochondrial calcium release, caspase-3, and cytochrome c levels, compared to control group (beta-actin). Statistical analysis was performed by SPSS 16. Results Apelin-13 at the dose of 2.5 μg/mL protected against IC50 Aβ (p<0.001). Apelin-13 at doses of 1, 2.5, and 5 μg/mL showed protective effects against the reactive oxygen species (ROS) produced by Aβ (p<0.001). Apelin-13 at doses of 2.5 and 5 μg/mL reduced calcium release, caspase-3, and cytochrome c (all p<0.001). Conclusions Apelin-13 prevented apoptosis, oxidative stress, and mitochondrial toxicity and can be a suitable option for treatment of AD. The appropriate treatment strategy for humans has to be investigated in future studies.

Polysaccharides, the mainly bioactive ingredient ofRadix Astragali, were evaluated for its effects on the oxidative stress induced by exhaustive swimming exercise of mice. A total of 48 mice were randomly divided into four groups: control group, low-dose polysaccharide fromAstragali radix(RAP) treated group, medium-dose RAP treated group, and high-dose RAP treated group. The control group received only distilled water ig, and the RAP treated groups received different doses of RAP (50, 100, and 200 mg/kg, ig) for 28 days. After the final treatment with RAP, the mice were subjected to swimming to exhaustion and the superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) were measured. The data showed that RAP promote increases in the activities of SOD, GPX and CAT in liver and muscle of mice, and the high-dose RAP (200 mg/kg) presented the best effect. These results indicated that RAP possessed protective effects against exercise-induced oxidative stress.

Etoposide (ETO) and methotrexate (MTX) are two effective chemotherapeutic drugs. However, the clinical use of these drugs is limited by its toxicity in normal tissues, especially in kidney and in liver tissues. Recombinant human erythropoietin (rhEPO), erythropoietin hormone, has also been shown to exert tissue protective effects. The purpose of this study was to explore the protective effect of rhEPO against oxidative stress and genotoxicity induced by ETO and MTX in vivo. Adult male Wistar rats were divided into 10 groups (6 animals each): control group, rhEPO alone group, ETO alone group, MTX alone group and rhEPO + ETO/MTX groups. In rhEPO + ETO/MTX groups, three doses of pretreatment with rhEPO were performed: 1000, 3000 and 6000 IU/kg. Our results showed that rhEPO pretreatment protects liver and kidney tissues against oxidative stress induced by the anticancer drugs. The glycoprotein decreased malondialdehyde (MDA) levels, reduced catalase activity and ameliorated glutathione depletion. Furthermore, we showed that rhEPO administration prevented drug-induced DNA damage accessed by comet test. Altogether, our results suggested a protective role of rhEPO, especially at 3000 IU/kg, against ETO- and MTX-induced oxidative stress and genotoxicity in vivo.

Abstract Objectives This study examined the possible protective roles of exogenous glycine (Gly) and L-Arginine (l-Arg) against Diclofenac (DIC)-induced gastro-duodenal damage in rats. Methods Rats were divided into Group A (control), Group B (DIC group) and Groups C–F which were pre-treated for five days with Gly1 (250 mg/kg), Gly2 (500 mg/kg), l-Arg1 (200 mg/kg) and l-Arg2 (400 mg/kg), respectively, before co-treatment with DIC for another three days. Hematological, biochemical and histopathological analyses were then carried out. Results DIC produced significant (p<0.05) reduction in PCV (13.82%), Hb (46.58%), RBC (30.53%), serum total protein (32.72%), albumin (28.44%) and globulin (38.01%) along with significant (p<0.05) elevation of serum MPO activity (83.30%), when compared with control. In addition, DIC increased gastric H2O2 and MDA levels by 33.93 and 48.59%, respectively, while the duodenal levels of the same parameters increased by 19.43 and 85.56%, respectively. Moreover, SOD, GPx and GST activities in the DIC group were significantly (p<0.05) reduced in the stomach (21.12, 24.35 and 51.28%, respectively) and duodenum (30.59, 16.35 and 37.90%, respectively), compared to control. Treatment with Gly and l-Arg resulted in significant amelioration of the DIC-induced alterations although l-Arg produced better amelioration of RBC (29.78%), total protein (10.12%), albumin (9.93%) and MPO (65.01%), compared to the DIC group. The protective effects of both amino acids against oxidative stress parameters and histological lesions were largely similar. Conclusions The data from this study suggest that Gly or l-Arg prevented DIC-induced gastro-duodenal toxicity and might, therefore be useful in improving the therapeutic index of DIC.

Aging is a neurological disease that is afforded by incidence of oxidative stress. Chitosan has received global interests due to its wide medical uses. Quercetin (Q) is a bioflavonoid and widely distributed in vegetables and fruits. Resveratrol is considered as a potent antioxidant and is a component of a wide range of foods. The using of either chitosan nanopartciles (CH-NPs), querectin (Q), and resveratrol (RV) to reduce the oxidative stress and biochemical alterations on brain and testicular tissues induced by D-galactose (DG) (100 mg/Kg) were the aim of the present study. This study investigated the probable protective effects of CH-NPs in two doses (140,280 mg/Kg), Q (20 mg/Kg) and RV (20 mg/Kg), against DG induced aging and neurological alterations. Brain antioxidant capacity as malonaldehyde (MDA), catalase (CAT), and glutathione reductase (GRx), as well as histopathological damages of the brain and testicular tissues were measured. The DG treated group had significantly elevated the oxidative stress markers by 96% and 91.4% in brain and testicular tissues respectively and lower significantly the antioxidant enzyme activities of both brain and testicular tissues than those of the control group by 86.95%, 69.27%, 83.07%, and 69.43%. Groups of DG that treated with a combination of CH-NPs in two doses, Q and RV, the levels of oxidative stress marker declined significantly by 68.70%, 76.64% in brain tissues and by 74.07% and 76.61% in testicular tissues, and the enzymatic antioxidants increased significantly by 75.55%, 79.24%, 62.32%, and 61.97% as compared to the DG group. The present results indicate that CH-NPs, Q, and RV have protective effects against DG-induced brain and testis tissue damage at the biochemical and histopathological levels. Mechanisms of this protective effect of used compounds against neurological and testicular toxicity may be due to the enhanced brain and testis antioxidant capacities.

ABSTRACT Background: Recent studies showed that Interleukin-8 (IL-8), activated cytokine immune response which plays an important role in the development of acute and chronic gastritis. Harmless anti-inflammatory therapeutic alternatives have been proposed, for example, the consumption of Sechium Edule Jacq. Swartz (chayote). Antioxidant (flavonoid) and cell regeneration (alkaloid) agents were found in chayote. This study aimed to determine the effect of chayote Sechium Edule Jacq. Swartz extracts on the level of IL-8 in Wistar rats with aspirin- induced gastritis. Subjects and Method: This was a randomized controlled trial (RCT) conducted at the laboratory of Mathematics and Natural Science, Universitas Sumatra Utara from January to February 2020. A total of 35 male Wistar rats was selected for this study and randomly allocated into 7 groups: (1) Negative control; (2) Positive control; (3) 100 mg/ kg BW chayote ethanol extract ; (4) 200 mg/kg BW chayote ethanol extract; (5) 100 mg/ kg BW chayote ethyl acetate fraction; (6) 200 mg/kg BW chayote ethyl acetate fraction; and (7) 20 mg omeprazole. The rats in positive control and treatment groups were induced with aspirin (200mg/ kg BW). The negative control group received no intervention. The dependent variable was level of IL-8 measured by ELISA. The independent variables were treatment status. The data were analyzed by One Way Anova and post hoc test. Results: The mean differences of IL-8 level were not statistically significant between study groups (p= 0.327). Mean of IL-8 level was higher in positive control group (Mean= 160.80; SD= 6.90) than in negative control group (Mean= 141.20; SD= 10.98). The lowest IL-8 level was in 100mg/ kg BW chayote ethanol extract group (Mean= 149.94; SD= 40.4), followed by 200mg/ kg BW (Mean= 152.4; SD= 30.73) and 100mg/ kg BW (Mean= 164.60; SD= 25.04) chayote ethyl acetate fraction groups, 20 mg omeprazole group (Mean= 170.60; SD= 21.58), and 200 mg/ kg BW chayote ethanol extract group (Mean= 176.80; SD= 10.98). Conclusion: The low dose (100mg/ kg BW) chayote ethanol extract has the most potential antiinflammation effect on in vitro gastritis with the lowest IL-8 level of all doses of chayote ethanol extract, chayote ethyl acetate fraction, and omeprazole.
