The present study was undertaken to evaluate the protective effects of Linum usitatissimum oil (LuO) against sub-chronic Roundup (RDP)-induced toxicity and oxidative stress in rats. Rats were divided into four groups: control group (no treatment), RDP group (Roundup at 269.9 mg/kg b.w.), LuO group (0.5 g/kg b.w. of LuO) and RDP+LuO group (RDP and LuO simultaneously). LuO decreased the ferric reducing antioxidant power (FRAP) (IC50=10.36 μg/ml) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) (IC50=22.85 mg/ml) in the tested tissues. The 30-day exposure of rats to RDP caused an increase in serum hepatic and renal markers: AST, ALT, ALP, LDH, γGT, bilirubin, urea, and creatinine. In addition, SOD, CAT and GST activities decreased by 43%, 61%, and 61%, respectively, while GPx activity, MDA and PCOs levels increased by 80%, 46%, 25%, respectively. LuO treatment alleviated hepatotoxicity in RDP-treated rats, showing improved levels of oxidative stress biomarkers and plasma biochemical parameters. The histological examination of the liver and kidney confirmed the changes in Roundup-treated rats and demonstrated the protective role of LuO.

Cadmium (Cd) is a toxic non-essential element, while calcium (Ca) is an essential element with high chemical similarity to Cd. Dietary intake is the major Cd exposure pathway for non-smokers. A multi-concentration dietary intervention experiment was designed to explore the optimum concentration of Ca in diet with obvious protective effects against the toxicity of livers and kidneys induced by Cd in mice. The mice were divided into six groups with different concentrations of Cd and Ca in their food: control-group (no Cd or Ca), Ca-group (100 g/kg Ca, without Cd), Cd-group (2 mg/kg Cd, without Ca), CaL+Cd-group (2 mg/kg Cd, 2 g/kg Ca), CaM+Cd-group (2 mg/kg Cd, 20 g/kg Ca) and CaH+Cd-group (2 mg/kg Cd, 100 g/kg Ca). The organ indexes, oxidative stress biomarkers, lesions and Cd concentrations were detected after a 30-day exposure period. Results showed that serum Aspartate Aminotransferase (AST) level in CaH+Cd-group was significantly lower than that in Cd-group, while close to that in control-group. The contents of Serum Blood Urea Nitrogen (BUN) in different groups showed the same trend. Concentrations of all oxidative stress biomarkers (GSH-Px, SOD, CAT, GSH and MDA) in CaH+Cd-group were close to the normal levels of control-group while significantly different from those in Cd-group. The only exception was the Malondialdehyde (MDA) levels in kidneys. This study suggests that Ca plays a protective role in relieving the Cd-induced toxicity of livers and kidneys and a concentration of 100 g/kg for Ca in diet showed the best protective effects. These findings could provide a clue for further studies concerning human diet intervention for Cd control.

Responses of wildlife to multiple stressors fit in the ecological concept of trade-off. While toxicity of non-steroidal anti-inflammatory drugs and heavy metals for free-ranging birds has been shown in single exposures, the present study aims to evaluate oxidative stress, and liver and kidney damage caused by single and combined effects of diclofenac and lead in the Japanese quail. Forty Japanese quail (Coturnix coturnix japonica) were divided into equal groups of controls, diclofenac, Pb, and Pb+diclofenac exposures. The birds were exposed to the respective chemicals through insertion of lead shots (1.5 g) into the crop on day 0 of the experiment and/or administration of 5 mg/kg of diclofenac intramuscularly in two treatments on days 0 and 5. Groups in liver and kidney tissues of birds were then compared after 10 days using histopathology and biochemistry markers such as glutathione reductase (GR), ferric reducing antioxidant power (FRAP), and lipid peroxidation measured as total thiobarbituric acid reactive species (TBARS). The liver damage score gradient was Pb+diclofenac exposure group > Pb exposure group > diclofenac exposure group and hepatic TBARS values were significantly increased in the group of birds exposed to a combination of diclofenac and lead compared to the healthy control group. The study has shown that, apart from the reported nephrotoxicity of diclofenac, hepatic toxicity should also be considered. Avian clinicians should be cautious when selecting drugs for therapy of wild birds with unknown history of exposure to toxic substances.

In this study, the effect of dietary antioxidants, such as astaxanthin and Flavangenol®, and a combination of both, in counteracting oxidative stress in streptozotocin-induced diabetes was investigated. Streptozotocin-induced diabetic rats were divided into four groups: control, astaxanthin, Flavangenol, and combined astaxanthin and Flavangenol (mix group). Each group other than the control group was fed with an astaxanthin diet (0.1 g/kg), Flavangenol diet (2.0 g/kg), or an astaxanthin (0.1 g/kg)-Flavangenol (2.0 g/kg) mixture diet, respectively. After 12 weeks of feeding, the results showed that the lipid peroxide levels of plasma and lens and the plasma triglyceride (TG) level in the mix group were significantly decreased by 44%, 20%, and 20%, respectively, compared with the control group. In the mix group, lipid peroxidation was also significantly reduced by 70% in the liver and 20% in the kidney compared with the control group. Furthermore, the level of urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) in the mix group was significantly lower, 36%, than the control group. The α-tocopherol concentrations in the plasma, liver, and kidney in the astaxanthin and mix groups were significantly higher, 3-9 times, than in the control group. The degree of cataract formation in the Flavangenol and mix groups tended to be lower than the control group. These results indicate that the combination of astaxanthin with Flvangenol has an improved protective effect on oxidative stress associated with streptozotocin-induced diabetes than either agent used alone. Thus, this combination may be beneficial in preventing the progression of diabetic complications.

Phenolamines and flavonoids are two important components in bee pollen. There are many reports on the bioactivity of flavonoids in bee pollen, but few on phenolamines. This study aims to separate and characterize the flavonoids and phenolamines from rape bee pollen, and compare their antioxidant activities and protective effects against oxidative stress. The rape bee pollen was separated to obtain 35% and 50% fractions, which were characterized by HPLC-ESI-QTOF-MS/MS. The results showed that the compounds in 35% fraction were quercetin and kaempferol glycosides, while the compounds in 50% fraction were phenolamines, including di-p-coumaroyl spermidine, p-coumaroyl caffeoyl hydroxyferuloyl spermine, di-p-coumaroyl hydroxyferuloyl spermine, and tri-p-coumaroyl spermidine. The antioxidant activities of phenolamines and flavonoids were evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and ferric reducing antioxidant power (FRAP) assays. It was found that the antioxidant activity of phenolamines was significantly higher than that of flavonoids. Moreover, phenolamines showed better protective effects than flavonoids on HepG2 cells injured by AAPH. Furthermore, phenolamines could significantly reduce the reactive oxygen species (ROS), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and increase the superoxide dismutase (SOD) and glutathione (GSH) levels. This study lays a foundation for the further understanding of phenolamines in rape bee pollen.

Diabetes mellitus is a metabolic disorder with increasing global prevalence. It is characterized by impaired glucose utilization that leads to chronic hyperglycemia which is a result of the body's inability to produce insulin (diabetes type I) or inability to make use of insulin (diabetes type II). Long-term hyperglycemia can cause damage to multiple systems, and microvascular and macrovascular complications lead to myocardial infarction, blindness, stroke and renal failure. Diabetes affected 382 million people globally in 2013, and it is estimated to rise up to 592 million by 2035. In spite of its management, both microvascular and macrovascular complications partly linked to oxidative stress are not efficiently prevented. Glibenclamide was approved on the U. S. market for treatment of diabetes type II in 1984. ATP-sensitive potassium channels (KATP) are widely distributed and present in a number of tissues including muscle, pancreatic beta cells and the brain. Glibenclamide closed KATP channels, which leads to depolarization of the cells and insulin secretion. Acupuncture is also a very significant therapeutic method in the complementary medicine. ST36 (Zusanli), CV4 (Guanyuan) and CV12 (Zhongwan) are several acupoints that have been used for treatment of diabetes. In this study for evaluating the effects of glibenclamide and electroacupuncture, 3 parameters such as malondialdehyde, ferric reducing antioxidant power and thiol will be measured. Malondialdehyde (MDA) is the organic compound and it is a marker for oxidative stress. Antioxidants are compounds that inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, thereby leading to chain reactions that may damage the cells of organisms. Antioxidants such as FRAP and thiol are useful parameters of assessment of oxidative stress. The aim of this study was to evaluate the effects of Electroacupuncture (EA) plus glibenclamide (G) as a novel therapy on diabetic rats and maybe for human. Fifty-four male Wistar rats were randomly divided to 9 groups: 1 non-diabetic control group and 8 diabetic groups (1 sham control group and 7 experimental groups; D/G 2.5 mg/kg, D/G 5 mg/kg, D/G 10 mg/kg, EA, D/EA/G 2.5 mg/kg, D/EA/G 5 mg/kg, and D/EA/G 10 mg/kg). Diabetes was induced by intraperitoneal injection of streptozotocin with high-fat diet. At the end of course, blood samples were obtained. Combination therapy of EA and glibenclamide 5 mg/kg decreased blood glucose better than single therapies (p<0.05) and showed 41 percent decrease in blood glucose as compared to D/G 5 mg/kg group. Combination of EA and glibenclamide 10 mg/kg showed the best effect for decreasing the malondialdehyde level (p<0.05) and also showed 43 percent decrease in comparison to D/G 10 mg/kg group. Combination of glibenclamide 2.5 mg/kg and EA increased the FRAP level better than other treatment groups (P<0.001) andachieved the ferric reducing antioxidant power level near to normal range. Combination of glibenclamide 10 mg/kg with EA increased the thiol concentration better than other treatment groups (P<0.001) and showed 4 percent increase in thiol concentration as compared to D/G 10 mg/kg group. These findings suggest that EA potentiates the effect of glibenclamide to protect animal model and maybe human against oxidative stress and damage.

Like several other anticancer drugs, methotrexate (MTX) causes side effects, such as neuropathic pain, hepatotoxicity, and nephrotoxicity. Abnormal production of reactive oxygen species has been suspected in the pathophysiology of MTX-induced hepatorenal toxicity. Therefore, the aim of this study was to investigate the probable protective role of vitamin C (Vit C) on oxidative stress induced by MTX in the liver and kidney tissues of rats. A total of 32 rats were randomly and equally divided into four groups. The first group served as the control group. The second group received a single dose of 20 mg/kg of MTX intraperitoneally. To demonstrate our hypothesis, the third and the fourth groups received 250 mg/kg of Vit C for 3 days by oral gavage, with or without MTX treatment. At the end of the study, the liver and kidney tissues of the rats were collected and examined using histology. Both the tissues were assayed for malondialdehyde concentration and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities. In hepatic and renal tissues, lipid peroxidation levels were increased, whereas SOD, CAT, and GSH-Px levels were decreased by MTX. All parameters, including CAT levels in hepatic tissue, were significantly restored after the administration of Vit C for 3 days. Similar to the biochemical findings, evidence of oxidative damage was examined in both types of tissues by histopathological examination. From the results of this study, we were able to observe that Vit C administration modulates the antioxidant redox system and reduces the renal and hepatic oxidative stress induced by MTX. Vit C can ameliorate the toxic effect of MTX in liver and kidney tissues of rat.

Restraint stress may be associated with elevated free radicals, and thus, chronic exposure to oxidative stress may cause tissue damage. Several studies have reported that carvacrol (CAR) has a protective effect against oxidative stress. The present study was designed to investigate the protective effects of CAR on restraint stress induced oxidative stress damage in the brain, liver, and kidney. For chronic restraint stress, rats were kept in the restrainers for 6 h every day, for 21 consecutive days. The animals received systemic administrations of CAR daily for 21 days. To evaluate the changes of the oxidative stress parameters following restraint stress, the levels of malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), and catalase (CAT) activities were measured in the brain, liver, and kidney. In the stressed animals that received vehicle, the MDA level was significantly higher (P<0.001) and the levels of GSH and antioxidant enzymes were significantly lower than the nonstressed animals (P<0.001). CAR ameliorated the changes in the stressed animals as compared with the control group (P<0.001). This study indicates that CAR can prevent restraint stress induced oxidative damage.

Cyclophosphamide (CP) was found to have a potential toxic effect on lung tissues. Raspberry ketones (RKs) are natural antioxidant chemicals isolated from red raspberries (Rubus ideaus). They are commonly used for weight loss and obesity. The current study aimed to evaluate the possible protective effects of RKs against lung toxicity induced by CP. Mice were allocated into six groups: (1) control group; (2) CP group: received a single intraperitoneal dose of CP (150 mg/kg, i.p.); and (3–6) mice were pre-treated orally with different doses of RKs (25, 50, 100, and 200 mg/kg) for 14 consecutive days, respectively, before the administration of an intraperitoneal dose of CP (150 mg/kg, i.p.). Mice were then sacrificed under anesthesia, then lungs were removed for histopathological and biochemical investigations. A single dose of CP markedly altered the levels of some oxidative stress biomarkers and resulted in the fragmentation of DNA in lung homogenates. Histological examination of CP-treated mice demonstrated diffuse alveolar damage that involved apparent hyalinization of membranes, thickening of inter alveolar septa, and proliferation of type II pneumocytes. The immunohistochemical results of CP-treated mice revealed strongly positive Bax and weakly positive proliferating cell nuclear antigen (PCNA) staining reactivity of the nuclei of the lining epithelium of the bronchioles and alveoli. CP activated the cyclooxygenase-2/nuclear factor-kappa B pathway. However, pre-treatment with RKs significantly attenuated CP-evoked alterations in the previously mentioned parameters, highlighting their antioxidant, anti-inflammatory, and anti-apoptotic potential. RKs may be suggested to be a potential candidate to ameliorate CP-induced pulmonary toxicity.

Background and Objectives. Allium hirtifolium Boiss (Persian shallot), as an edible vegetable, has several pharmacological properties including antimicrobial, anti-inflammatory, and antioxidative effects, while its protective effects in liver cells are controversial. In this study, we examined the effect of A. hirtifolium extract on cadmium- (Cd-) induced hepatotoxicity in rats. Materials and Methods. Thirty-six male Wistar rats were divided into six groups: groups 1, 2, and 3 received vehicle, Cd (100 mg/L/day by drinking water), and A. hirtifolium extract (200 mg/kg/day; orally), respectively. Groups 4, 5, and 6 were Cd groups which were treated with A. hirtifolium extract (50, 100, and 200 mg/kg/day, respectively). After 2 weeks, liver enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) and also oxidative stress biomarkers including lipid peroxidation (LPO), total antioxidant capacity (TAC), total thiol molecule (TTM), and the histopathological changes were determined using standard procedure. Results. The findings showed that Cd caused a remarkable rise in levels of serum hepatic enzymes such as ALT (P<0.001), AST (P<0.01) and ALP (P<0.001) compared with the control group. In addition, Cd led to the decreasing of the levels of TTM (P<0.001) and TAC (P<0.001) and increasing of LPO (P<0.001) in liver tissue in comparison with the control group. In this regard, remarkable vascular congestion, hepatocellular degeneration, and vacuolization were observed in hepatic tissue of Cd-treated rats. Following the administration of A. hirtifolium extract, a significant improvement was observed in the functional and oxidative stress indices of hepatic tissue alongside histopathologic changes. Conclusion. The current study indicated that the A. hirtifolium extract might prevent hepatic oxidative injury by improving oxidant/antioxidant balance in rats exposed to Cd.

The pathophysiological mechanisms of migraine transformation are debated. Modifications of plasma oxidative stress biomarkers have been described in chronic migraine. OnabotulintoxinA (BoNT/A) treatment, approved for chronic migraine prophylaxis, possibly reduces pain neurotransmitters release and oxidative stress products. Aims of our study were to investigate differences in the levels of selected plasmatic oxidative stress biomarkers (Advanced Oxidation Protein Products (AOPP), Ferric Reducing Antioxidant Power (FRAP), Thiolic Groups (SH)) comparing chronic migraineurs (CM) and healthy controls (HC). We also explored possible clinical and biochemical modifications in the CM group after six months of treatment with BoNT/A. At the baseline, we found higher values of AOPP (p < 0.001), and lower values of SH (p < 0.001) and FRAP (p = 0.005) in the CM group. At the six-month follow-up we found a reduction of AOPP (p < 0.001) and an increase of FRAP (p < 0.001) and SH (p = 0.023) within the CM group. BoNT/A treatment improved migraine symptoms in the CM group. We confirmed previous reports of imbalanced antioxidant mechanisms in chronic migraine showing lower antioxidant capacities in patients than controls. BoNT/A improved the levels of plasma oxidative stress biomarkers and confirmed its role as an effective prophylactic treatment for CM. Other studies should investigate the potential antioxidant properties of BoNT/A treatment.
