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.

Royal jelly is a bee product frequently used in pharmaceutical, food and cosmetic industries due to its biological activities. The present study aimed to determine the effects of royal jelly on malathion-induced toxicity and biochemical changes. The rats that were used as experimental animals in the study were divided into 6 groups. Control group rats were administered nothing, while carrier chemicals (1% DMSO) were administered to sham group rats. Malathion group (MAL) rats were injected with 0.8 g/kg malathion in DMSO subcutaneously. Saline solution that included 100 mg/kg royal jelly was administered with gavage to the rats in the royal jelly group (RJ). 100 mg/kg royal jelly was administered to RJ+MAL group rats via gavage 1 hour before the injection of 0.8 g/kg malathion. 100 mg/kg royal jelly was administered to MAL+RJ group rats via gavage 1 hour after the injection of 0.8 g/kg malathion. After the experimental process (24 hours), blood samples were taken from the rats in each group under anesthesia (ketamine+xylazine). MDA, NO, GSH, GPx (glutathione peroxidase), CAT, SOD and AChE activities were determined in blood, liver, kidney and brain tissues. It was found that erythrocyte, liver, kidney and brain MDA (malondialdehyde) concentrations in MAL groups were statistically significantly higher when compared to the other groups (p<0.05). It was observed that GSH (glutathione) concentrations increased in the brain, while they decreased in erythrocyte, liver and kidney in the MAL group when compared to the control and sham groups. CAT (catalase) concentration significantly decreased in erythrocyte, liver, kidney and brain tissues in the MAL group when compared to the control and sham groups (p<0.05). SOD (superoxide dismutase) concentration in the MAL group decreased significantly (p<0.05) when compared to other groups, while SOD concentration increased significantly in the therapy and prevention groups (p<0.05) when compared to the others. It was found that serum acetylcholinesterase (AChE) concentration was significantly lower in the MAL group when compared to sham and control groups (p<0.05). Thus, it was concluded that malathion led to lipid peroxidation and oxidative stress in MDA and NO (nitric oxide) levels and toxicity in AChE activities. It was also determined that royal jelly could be effective against oxidative damage and toxicity. The findings suggested that the antioxidant effect of royal jelly could support the treatment of malathion, which is one of the insecticides that contain organophosphate and could lead to oxidative stress. It is considered that the prophylactic characteristics of royal jelly was more effective on malathion toxicity when compared to therapatic properties.

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.

Background & Objective: Crocetin, an active ingredient of saffron, has been recognized as a potent antioxidant. Plant extracts or their components may be useful in ameliorating the various diseases, including neurodegenerative disorders. This study investigated the effects of crocetin on oxidative damage induced by chronic restraint stress in the rat brain. For this reason, rats were kept in the restrainers for 1 hour every day, for 21 consecutive days. The animals were injected crocetin (20, 40, 60 mg/kg) or vehicle daily for 21 days. Findings showed that the immobility time significantly increased in the rodents subjected to the chronic stress compared with the normal group. However, the number of crossing beams in the rats submitted to the chronic stress significantly decreased versus the non-stress rats. Treatment with crocetin ameliorated the immobility time and the number of crossing in the chronic restraint stress rats versus the non-treated stress group. Crocetin also reverted the levels of MDA and GSH and also the activities of antioxidant enzymes to the normal levels in the stress groups. Conclusion: The present study suggests that crocetin may be useful for the management of depressantlike effects induced by chronic stress through decreasing oxidative damage in the brain.

The purpose of the present study was to determine concentrations of some biochemical parameters and oxidative stress levels in cattle with brucellosis. For this purpose, a study group included with 20 cattle with brucellosis and a control group with 10 clinically healthy cattle were used. Blood samples were collected into the tubes (with and without anticoagulant agent) from the Jugular vein of animals in each group. The reduced glutathione (GSH) in whole blood and levels of malondialdehyde (MDA) and nitric oxide (NO) were determined spectrophotometrically. Additionally, aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, creatinine and iron (Fe) levels in serum samples were colorimetrically determined. Compared with the animals in the control group, it was determined that cattle with brucellosis had significantly (P<0.01) higher levels of AST, ALT, creatinine and NO and lower level of Fe. The increases of MDA and GSH levels were moderate and significantly important (P<0.05) while serum urea manner was not significantly altered. It was determined that significant alterations occurred in various biochemical parameters and antioxidant activity decreased in cattle with brucellosis.

Background: Taurine is a conditional essential nutrient in man, with proven antioxidant property. This study was designed to evaluate the protective effects of taurine against atrazine (ATZ)-induced hepatic and renal oxidative toxicity in rats.Methods: Wistar rats were orally exposed to ATZ (1/10 LD50) alone or in combination with taurine at 1.5% w/v and 3% w/v in their drinking water for 30 days. After treatment, the liver and kidney were excised for biochemical assays by spectrophotometric methods.Results: Exposure to ATZ significantly elevated hepatic and renal malondialdehyde (MDA) levels when compared to control (p < 0.05). Advanced oxidized protein products (AOPP) were equally increased in these tissues on exposure to ATZ. In addition, reduced glutathione (GSH) and total antioxidant capacity (TAC) were markedly depleted in both organs on exposure to ATZ. Furthermore, activities of the antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT) were inhibited by ATZ compared to the control. However, co-treatment with taurine attenuated the oxidative responses generated by ATZ exposure in the rats, with the high dose of the amino acid normalizing most of the toxic effects.Conclusion: The study suggested that taurine can protect against ATZ-induced oxidative stress.

Primaquine and chloroquine are used for the treatment of malaria; evidence from the literature suggests that these drugs may induce oxidative stress. In this study we investigated the effects of primaquine and chloroquine on oxidative damage and DNA damage in brain, liver and kidney of rats after 7, 14 and 21 days of administration. Our results demonstrated that primaquine causes DNA damage in brain after 7, 14 and 21 days, and in liver after 7 and 14 days. Moreover, primaquine increases TBARS levels in the kidney and protein carbonyls in the brain after 14 days, and decreases protein carbonyls in the liver after 7 days. Whereas chloroquine causes DNA damage in the kidney after 7 and 14 days, and in the liver after 14 and 21 days, increases TBARS levels in the kidney after 7 days, and decreases TBARS levels in the brain after 21 days. Moreover, decreases protein carbonyls in the liver after 7 and 14 days, and in the brain after 7 and 21 days. However, chloroquine treatment for 14 days increases protein carbonyls in the brain and kidney. In conclusion, these results showed that prolonged treatment with antimalarial may adversely affect the DNA.

AbstractObesity and the brain are linked since the brain can control the weight of the body through its neurotransmitters. The aim of the present study was to investigate the effect of high-fat diet (HFD)-induced obesity on brain functioning through the measurement of brain glutamate, dopamine, and serotonin metabolic pools. In the present study, two groups of rats served as subjects. Group 1 was fed a normal diet and named as the lean group. Group 2 was fed an HFD for 4 weeks and named as the obese group. Markers of oxidative stress (malondialdehyde, glutathione, glutathione-s-transferase, and vitamin C), inflammatory cytokines (interleukin [IL]-6 and IL-12), and leptin along with a lipid profile (cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein levels) were measured in the serum. Neurotransmitters dopamine, serotonin, and glutamate were measured in brain tissue. Fecal samples were collected for observing changes in gut flora. In brain tissue, significantly high levels of dopamine and glutamate as well as significantly low levels of serotonin were found in the obese group compared to those in the lean group (P > 0.001) and were discussed in relation to the biochemical profile in the serum. It was also noted that the HFD affected bacterial gut composition in comparison to the control group with gram-positive cocci dominance in the control group compared to obese. The results of the present study confirm that obesity is linked to inflammation, oxidative stress, dyslipidemic processes, and altered brain neurotransmitter levels that can cause obesity-related neuropsychiatric complications.

Background: Cardiovascular complications are the leading cause of morbidity and mortality at any stage of chronic kidney disease (CKD). Moreover, the high rate of cardiovascular mortality observed in these patients is associated with an accelerated atherosclerosis process that likely starts at the early stages of CKD. Thus, traditional and non-traditional or uremic-related factors represent a link between CKD and cardiovascular risk. Among non-conventional risk factors, particular focus has been placed on anaemia, mineral and bone disorders, inflammation, malnutrition and oxidative stress and, in this regard, connections have been reported between oxidative stress and cardiovascular disease in dialysis patients. Methods: We evaluated the oxidation process in different molecular lines (proteins, lipids and genetic material) in 155 non-dialysis patients at different stages of CKD and 45 healthy controls. To assess oxidative stress status, we analyzed oxidized glutathione (GSSG), reduced glutathione (GSH) and the oxidized/reduced glutathione ratio (GSSG/GSH) and other oxidation indicators, including malondialdehyde (MDA) and 8-oxo-2’-deoxyguanosine (8-oxo-dG). Results: An active grade of oxidative stress was found from the early stages of CKD onwards, which affected all of the molecular lines studied. We observed a heightened oxidative state (indicated by a higher level of oxidized molecules together with decreased levels of antioxidant molecules) as kidney function declined. Furthermore, oxidative stress-related alterations were significantly greater in CKD patients than in the control group. Conclusions: CKD patients exhibit significantly higher oxidative stress than healthy individuals, and these alterations intensify as eGFR declines, showing significant differences between CKD stages. Thus, future research is warranted to provide clearer results in this area.

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.

This study aimed to investigate the role of oxidative stress parameters (ROMs, OXY, SHp), the Oxidative Stress index (OSi), and High Mobility Group Box-1 protein (HMGB-1) in canine leishmaniosis (CanL). For this study, thirty dogs, naturally infected with Leishmania spp. (Leishmania Group, LEISH) and ten healthy adult dogs (control group, CTR) were included. The diagnosis of CanL was performed by a cytological examination of lymph nodes, real time polymerase chain reaction on biological tissues (lymph nodes and whole blood), and an immunofluorescence antibody test (IFAT) for the detection of anti-Leishmania antibodies associated with clinical signs such as dermatitis, lymphadenopathy, onychogryphosis, weight loss, cachexia, lameness, conjunctivitis, epistaxis, and hepatosplenomegaly. The HMGB-1 and oxidative stress parameters of the LEISH Group were compared with the values recorded in the CTR group (Mann Whitney Test, p < 0.05). Spearman rank correlation was applied to evaluate the correlation between the HMGB-1, oxidative stress biomarkers, hematological and biochemical parameters in the LEISH Group. Results showed statistically significant higher values of SHp in the LEISH Group. Specific correlation between the ROMs and the number of red blood cells, and between HGMB-1 and SHp were recorded. These preliminary data may suggest the potential role of oxidative stress in the pathogenesis of CanL. Further studies are undoubtedly required to evaluate the direct correlation between inflammation parameters with the different stages of CanL. Similarly, further research should investigate the role of ROMs in the onset of anemia.
