Vancomycin-induced nephrotoxicity has been reported to occur in 5%–25% of patients who were administered with it. Several natural antioxidants were found to be effective against drug-induced toxicity. We evaluated the possible protective effects of spirulina and pycnogenol alone or in combination on vancomycin-induced renal cortical oxidative stress. Forty-nine rats were randomly divided into 7 groups: group I, control; group II, received spirulina 1000 mg/kg per day; group III, received pycnogenol 200 mg/kg per day; group IV, received vancomycin 200 mg/kg per day every 12 h; group V, (spirulina + vancomycin); group VI, (pycnogenol + vancomycin); and group VII, (pycnogenol + spirulina + vancomycin). At the end of the experiment, kidney functions were estimated and then the kidneys were removed, weighed, and sampled for histopathological, immunohistochemistry, and biochemical studies. Administration of spirulina and pycnogenol alone or in combination decreased elevated serum creatinine, blood urea nitrogen, renal malondialdehyde, and immunoexpression of the proapoptotic protein (Bax), autophagic marker protein (LC3/B), and inducible nitric oxide synthase induced by vancomycin. They increased reduced glutathione, glutathione peroxidase, superoxide dismutase, and immunoexpression of the antiapoptotic protein (Bcl2). They also ameliorated the morphological changes induced by vancomycin. The combination therapy of spirulina and pycnogenol showed better protective effects than the corresponding monotherapy.

Background: Long-term administration of valproic acid (VPA) is known to promote renal tubular injury mediated by increase in renal oxidative stress. Recent evidence indicates that natural antioxidants are alternative to attenuate oxidative stress and kidney damage. Objective: This study was performed to investigate the protective effects of n-butanol extract of Rhanterium suaveolens, vitamin E (Vit E) and vitamin C (Vit C) against VPA induced nephrotoxicity in mice. Methods: Mice were randomly divided into 6 groups (n: 8) and treated daily for 12 days. They received VPA (300 mg/kg intraperitoneally (ip)), buthanolic extract (100 mg/kg), Vit E (100 mg/kg), and Vit C (16.66 mg/kg) 1h prior to administration of VPA. On day 13, blood and Kidneys samples were analyzed for biomarker levels and histopathological changes. Kidneys homogenates were used for determination of oxidative stress parameters that include malondialdehyde (MDA), glutathione (GSH) level and glutathione peroxidase (GPx) activity. Result: Treatment with VPA showed a significant increase in the levels of serum creatinine, urea and malondialdehyde (MDA) and decreasing the enzymatic activity (GPx) as well as GSH levels in kidney with marked necrotic epithelial cells and infiltration in kidney sections as compared to the control group. Pretreatment with the n-butanol extract of R. suaveolens, Vit C or Vit E 1 h prior to administration of VPA showed a significant decrease in the levels of serum creatinine, urea, and MDA, as well as an improvement in the antioxidant elements and histological changes compared to those previously seen in the group treated with VPA alone. Conclusion: It is concluded that n-butanol extract of R. suaveolens, Vit C and Vit E pretreatment effectively improved renal function and tissue oxidative damage caused by VPA.

The current study was designed to determine the antioxidant effects of vitamin C and vitamin E against oxidative stress induced by vancomycin in some antioxidants changes in the male rats. The study was conducted in the animal house of the Faculty of Science/University of Kufa for the period from April, 2018 to May, 2018 on 119 animals of male rats aged 2.5–3 months and the weight of 150-200 gm. Two experiments designed in this study addressed the first and two experiments to study the oxidative effect of vancomycin in addition to the protective effects of vitamin C and vitamin E to reduce these effects in the treatment of animals for one week and three weeks with vancomycin and vancomycin plus vitamins. The results indicated a significant increase (p less than 0.05) in the MDA, CAT, and significant decrease (p less than 0.05) in SOD, and GPX. In the animals treated with vancomycin 40,60 mg/kg only compared to the control group for the two periods of administration at the same time occur a significant decrease(p less than 0.05) in the MDA, CAT and a significant increase (p less than 0.05) in the SOD and GPX after treated animals with vancomycin 40,60 mg/kg with vitamin C and vitamin E for a period of one and three weeks compared with vancomycin group.

The models of oxidative damage-induced aging were established by adding ethanol (C2H5OH), hydrogen peroxide (H2O2) and 6-hydroxydopamine (6-OHDA) to zebrafish embryos in this research. To find effective protective drugs/foods, Salvianolic acid B (Sal B) was added after the embryos were treated by these oxidative reagents. After being treated with ethanol, H2O2 and 6-OHDA, the morphological changes were obvious and the deformities included spinal curvature, heart bleeding, liver bleeding, yolk sac deformity and pericardial edema, and the expression of oxidative stress-related genes Nrf2b, sod1 and sod2 and aging-related genes myl2a and selenbp1 were significantly up-regulated compared to the control group. While after adding 0.05 μg/mL and 0.5 μg/mL Sal B to the ethanol-treated group, death rates and MDA levels decreased, the activity of antioxidant enzyme (SOD, CAT and GSH-Px) changed and Nrf2b, sod1, sod2, myl2a, selenbp1, p53 and p21 were down-regulated compared to the ethanol-treated group. The bioinformatics analysis also showed that oxidative stress-related factors were associated with a variety of cellular functions and physiological pathways. In conclusion, Sal B can protect against aging through regulating the Keap1/Nrf2 pathway as well as antioxidative genes and enzyme activity.

Abstract Background Typha capensis is one of the medicinal plants commonly used to manage male fertility problems. The objective of the present study was to assess its fertility-promoting effects in a rat model of cadmium-induced infertility. Methods A total of 30 male Wister rats were randomly divided into five groups of six animals each. Animals of group I, which served as control, were administered with cadmium chloride (CdCl2; 2.5 mg/kg) and normal saline (2 mL/kg). Group II was served with 0.5 mL normal saline only. Animals of groups III–V were treated with CdCl2 (2.5 mg/kg) plus T. capensis extract at doses of 100, 200, and 400 mg/kg, respectively. Animals were sacrificed under sedation. Testes and epididymal weights and sperm count were determined. Histological assessment of the testes was conducted. Results T. capensis at any dose did not improve (p > 0.05) testicular and epididymal weights compared with those of the CdCl2-exposed control group. Histology revealed moderate necrosis in the same group. T. capensis modestly increased the sperm count by 14%, 31%, and 35%, for groups treated with the extract at doses 100, 200, and 400 mg/kg, respectively, when compared with the CdCl2 control group, although the differences were not significant statistically (p > 0.05). Conclusions Results of our study demonstrated that T. capensis can neither offer protective effects against oxidative stress nor promote fertility in an animal model of cadmium-induced infertility.

This study was conducted to evaluate the potential cardioprotective effect of cardamom (CAR) against myocardial injuries induced by doxorubicin (DOX) in rats through investigation of histological alterations and the associated oxidative stress, apoptosis, inflammation, and angiogenesis. This study included 30 adult male albino rats that were randomized to 3 groups (n = 10/group): group I (control), group II (DOX) rats injected with DOX (2.5 mg/kg body weight [BW] i.p.) every other day for 2 weeks, and group III (CAR+DOX) received CAR extract (200 mg/kg BW) orally for 3 weeks, and 1 week later (starting from the 2nd week) they were injected with DOX (2.5 mg/kg BW i.p.) every other day for 2 weeks. Rats treated with DOX alone exhibited notable myocardial damage (discontinuity and disorganization of cardiac muscle fibers, mononuclear cell infiltration, and apparent increases in collagen fiber deposition) accompanied by loss of function (revealed by elevated serum levels of lactate dehydrogenase, creatine kinase, and cardiac troponin), induction of oxidative stress (indicated by higher levels of nitric oxide and malon­dialdehyde, and lower levels of superoxide dismutase, catalase, and glutathione peroxidase), apoptosis (evidenced by high caspase 3 activity and immunostaining), and inflammation (marked by high cardiac NFκB level). However, administration of CAR not only ameliorated all deleterious effects of DOX but also induced angiogenesis, as indicated by a significant increase in VEGF immunoreactivity. These data indicate that CAR could relieve DOX-induced cardiotoxicity, at least in part, via reductions in oxidative stress, apoptosis, and inflammation and increased tissue regeneration via induction of angiogenesis. Therefore, CAR could be a promising cytoprotective agent against DOX cardiotoxicity.

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.

This study compared the possible protective effects of silymarin and melatonin against gentamicin (GEN)-induced nephrotoxicity in rats. Rats were allocated to 6 groups: Group I, control group; Groups II and III, administered with silymarin or melatonin; Group IV, injected with GEN; and Groups V and VI, administered with silymarin or melatonin, and then injected with GEN. Compared with the rats in the control group, all rats injected with GEN significantly presented elevated levels of serum creatinine and urea that was accompanied by an increase in relative kidney weight, increase in renal reactive oxygen species (ROS) and malondialdehyde (MDA) levels, and reduction in renal glutathione (GSH) level and superoxide dismutase (SOD) activity. Silymarin and melatonin pretreatment significantly lowered the elevated serum urea and creatinine concentration, kidney weight, and renal ROS and MDA levels. In addition, silymarin and melatonin significantly enhanced renal GSH level and SOD activity. This study indicates that silymarin and melatonin can attenuate renal injury in rats treated with GEN possibly by reducing the ROS level.

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.

Intraperitoneal injection of ferric nitrilotriacetate (Fe-NTA) to rats and mice results in iron-induced free radical injury and cancer in kidneys. This study was designed to investigate the effect of catechin, a bioflavonoid with antioxidant potential, on Fe-NTA-induced nephrotoxicity in rats. Four groups were employed in the present study. Group I served as control group, Group II animals received Fe-NTA (8 mg iron/kg body weight i.p.), Group III animals were given 40 mg/kg catechin p.o. twice a day for 4 days and on the 5th day Fe-NTA was challenged, and Group IV animals received catechin alone for 4 days. Renal function was assessed by measuring plasma creatinine and blood urea nitrogen. The oxidative stress was measured by renal malondialdehyde levels, reduced glutathione levels and by enzymatic activity of catalase, glutathione reductase and superoxide dismutase. One hour after a single intraperitoneal (i.p.) injection of Fe-NTA (8 mg iron/kg), a marked deterioration of renal architecture, renal function and severe oxidative stress was observed. Pretreatment of animals with catechin markedly attenuated renal dysfunction, reduced elevated thiobarbituric acid reacting substances (TBARS), restored the depleted renal antioxidant enzymes and normalized the renal morphological alterations. These results clearly demonstrate the role of oxidative stress and its relation to renal dysfunction, and suggest a protective effect of catechin on Fe-NTA-induced nephrotoxicity in rats.
