The aim of this research was to investigate the potential effect of methanolic extract of Scurrula atropurpurea (MESA) in reducing oxidative stress through observation of superoxide dismutase (SOD) activity and malondialdehyde (MDA) concentration in mice. In this research, 25 male mice were divided into four groups with five replications. Group I (K1, without MESA) was considered as a control group, while Group II (K2), III (K3), and IV (K4) were given 1000, 2000, and 4000 mg MESA/kg BW, respectively. After 14 days, SOD activity and MDA concentration were measured spectrophotometrically. The SOD activity did not significantly increased (P>0.05) in group K1, K2, K3, and K4 with values were 19.469±2.072, 17.4±1.373, 20.53±3.411, and 23.87±2.528 U/ml, respectively. In contrast, MDA concentration was decreased (P>0.05) with values of 492.750±19.418, 492.750±19.418, 457.125±30.095, 454.625±19.080, and 475.875±37.659 ng/mL in groups K1, K2, K3, and K4, respectively. It can be concluded that the administration of  MESA tend to increase SOD activity and decrease MDA concentration in this study, thus might be able to reduce  oxidative stress in mice.

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.

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.

Curcumin, a natural phenolic compound is an anti-tumor agent with anti-inflammatory and anti-oxidant properties. The aim of this research was to evaluate oxidative stress levels, the antioxidant activity and Curcumin concentrations by high performance liquid chromatography (HPLC) in an acute experimental inflammation induced by Turpentine oil (intramuscular 0.6 mg kg-1 body weight) and to compare a prophylactic versus a therapeutic regimen of Curcumin (oral suspension of 150 mg Curcumin kg-1 rat weight). Sixteen adult male Wistar rats were assigned to four groups: Control, Group I (Curcumin only), Group II (Curcumin administration, then induced inflammation after 1 hour) and Group III (induced inflammation then Curcumin administration after 2 hours). Oxidative stress was assessed by measuring serum malondialdehide and carbonylated proteins, while systemic and local total antioxidant capacity was determined by ABTS. Local tissue changes (muscle, kidney, liver) were analysed using histopathology. Results showed that acute inflammation significantly increased lipid peroxidation in Groups II and III compared to Control and Group I. A significantly reduced total antioxidant capacity (ATBS) was present in serum and kidney in Group II, also in muscle and kidney in Group III. ABTS levels were significantly increased only in the liver tissue of the animals in Groups II and III with induced inflammation as compared to Group I. This study proved the potential of Curcumin in reducing oxidative stress in both prophylactic and therapeutic regimens.

The present study targeted the brain mitochondria dysfunction in Swiss albino mice through carbon tetrachloride intoxication and its treatment with Zingerone. It is proposed that brain mitochondria is the main organelle responsible for oxidative stress by producing  reactive oxygen species (ROS). Swiss albino mice were divided into four groups; Group-1 was control; Group-2 was carbon tetrachloride (CCl4) toxic (1.5mg kg-1 bm i.p two days in a week.); Group-3 was pretreated with Zingerone (100 mg kg-1 b.m)  a day before  the administration of CCl4 and Group-4 was only Zingerone (100 mg kg-1 bm) given orally for 15days once in a day. At the end of the experiment mice were sacrificed and mitochondria were isolated from brain. Isolated brain mitochondria were further analyzed for oxidative stress marker. Thiobarbituric acid reactive substance (TBARS) content was increased significantly by CCl4 administration in Group-II as compared to the control Group-I, while the antioxidant (GSH) and other antioxidant enzyme GPx , GR, and CAT was depleted significantly in CCl4 treated Group-II as compare to control Group-I. Zingerone protected the  toxicity of brain mitochondria by reducing the lipid peroxidation and enhancing the antioxidant enzyme in Group-III and there was no significant changes were noticed in Group-IV as  compared to Group-I. Overall results showed the potential effects of Zingerone in protecting the neuronal cell loss by oxidative stress. Thus, the  present study indicated that the Zingerone may be used as the potential therapeutic tools for the prevention of CCl4 induced brain mitochondrial toxicity.

Abstract Introduction: Varicocele is the predominant cause of male infertility and was found in 19% - 41% of men with primary infertility and 45% - 81% of men with secondary infertility. Human adipose Derived Stem Cells (hADSC) can suppress oxidative stress in some oxidative injury model. Therefore, this study would like to investigate the effect of intratesticular hADSC injection on MDA level and spermatogenesis process by histopathological examination in the varicocele rat model.Method: This is an experimental study. A total sampling of 9 male Wistar rats were divided into three groups. Group I consist of 1 Wistar rats without any treatment or model (sham group), group II consist of 4 Wistar rats with varicocele model without hADSC therapy (control group), and group III consist of 4 Wistar rats with varicocele model and were given injections of 1.0x106 hADSC cells intratesticularly 30 days after model was made (therapy group). Testicular tissue was harvested for evaluation. Results: In all varicocele model rats (group II and III), the result of MDA level in therapy group (2.53 mol/liter) was significantly lower than the MDA level in control group (4.43 mol/liter) (p = 0.01). On histopathological examination, the average Johnson's Score in the therapy and control group was 9,77 and 9,18, respectively. The analysis showed Johnson’s score in the intervention group was significantly higher (p = 0.018). Conclusion: Intratesticular injection of hADSC can help reduce MDA levels and improve spermatogenesis process, which is damaged by varicoceles.

Abstract Background: To study the morphologic and biochemical changes in the retina and sclera induced by form deprivation high myopia (FDHM) in guinea pigs and explore the possible mechanisms of FDHM formation.Methods: Forty 3-week-old guinea pigs were randomized into the blank control (Group I, 20 cases) and model groups (20 cases). In the model group, the right eyes of the guinea pigs were sutured for 8 weeks to induce FDHM (Group II) and the left eyes were considered a self-control group (Group III). The refractive errors were measured with retinoscopy. The anterior chamber depth (AC), lens thickness (L), vitreous chamber depth (V) and axial length (AL) were measured using ultrasonometry A. Retinal and scleral morphology and ultrastructural features were observed with light and electron microscopy. The malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in the retina and sclera were detected with a chemical colorimetric assay.Results: After eight weeks of stitching, the refractive errors of Group II changed from (+3.59±0.33) D to (-7.96±0.55) D, and these values were significantly higher than those of Group I (+0.89±0.32) D and Group III (-0.55±0.49) D (P < 0.05). The vitreous chamber depth (4.12±0.13) mm and axial length (8.93±0.22) mm of Group II were significantly longer than those of Group I [(3.71±0.23) mm and (7.95±0.37) mm, respectively] and Group III [(3.93±0.04) mm and (8.01±0.15) mm, respectively] (P < 0.05). With the prolongation of form deprivation (FD), the retina and scleral tissues showed thinning, the ganglion cell and inner and outer nuclear layers of the retina became decreased, and the arrangement was disordered. In Group II, the SOD activity was significantly lower than that in Group I and Group III; the MDA content was significantly higher than that in Group I and Group III. The differences were statistically significant (P < 0.05).Conclusions: These findings suggested that in the FDHM guinea pigs model, the refractive errors, the vitreous chamber depth, and axial length increased significantly with prolongation of monocular FD time, and morphological structural changes in the retina and sclera were observed. Oxygen free radicals might participate in the formation of FDHM.

Introduction. A lot of studies have dealt with the oxidative stress in pulmonary diseases, and some of them with tuberculosis as well. The aim of this study was to examine the antioxidant enzyme level (superoxide dismutase, glutathione peroxidase, catalase) and the lipid peroxidation products in patients with tuberculosis. Material and methods. Forty patients with tuberculosis were included in the study. The examined parameters were measured before and three weeks after the beginning of the antituberculosis treatment (group I). The control group included 40 healthy persons (group II). Results. The superoxide dismutase level was significantly lower in group I in both measurements (p<0.001 and p<0.01) in relation to group II, but there were no significant changes in its level during the therapy. During the treatment, the glutation peroxidase level significantly increased (p<0.05), and in relation to group II, its level was significantly lower in both measurements in group I (p<0.001 and p<0.001). The catalase level significantly increased during the treatment, but there was no significant difference in relation to group II level. There was no significant difference in relation to the lipid peroxidase products between the groups. Discussion. Our study group had reduced antioxidant enzyme level and some of them showed significant improvement during the treatment. The lipid peroxidase product level was stable. Conclusion. In patients with tuberculosis the antioxidative status is lower and its level and possible development of the oxidative stress depend on the disease severity.

Malathion can be ingested, inhaled, or absorbed through the skin, but acute toxicity is maximized when administered orally. Intravenous lipid emulsion (ILE) treatment is used as a new therapeutic method in cases of systemic toxicity caused by some lipid soluble agents. This study aimed to examine the potential treatment effect of ILE on rat lung tissue in a toxicokinetic model of malathion exposure. Twenty-one adult Wistar albino rats were randomly divided into three equal groups. The groups were organized as group I (control), group II (malathion), and group III (malathion + ILE treatment). Malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) were evaluated in lung tissues. Immunohistochemical and Western blot analyses were performed to determine the bax, bcl-2, and caspase-3 expression levels. Tissue GSH-Px and SOD activities were decreased and MDA levels were increased in the malathion group. ILE administration increased GSH-Px and SOD activity and decreased MDA levels compared to the malathion group. Furthermore, expression of bax, bcl-2, and caspase-3 significantly increased in the malathion group, and ILE infusion reduced these expression levels. The present study revealed that acute oral malathion administration increased oxidative stress and apoptosis in the lung tissue of rats. ILE infusion prevented oxidative stress and decreased the deleterious effects of malathion. Taken together, the findings of our study suggest that lipid emulsion infusion has treatment efficacy on malathion-induced lung toxicity.

Objective. Selenium, as an antioxidant, has been implicated in the development of autoimmune thyroiditis (AIT). Many studies showed selenium supplementation could decrease thyroid autoantibodies in patients with AIT. However, the underlying mechanisms have not been well determined. Therefore, we performed a clinical study to investigate the possible mechanism of beneficial effects of selenium treatment on AIT patients. Methods. Forty euthyroid patients with AIT were randomized into two groups. Group I was treated with 200 μg/day selenium supplementation, and group II received a placebo over a 3-month period. Thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), antithyroglobulin antibody (TgAb), malondialdehyde (MDA), total antioxidant capacity (TAC), and superoxide dismutase (SOD) were measured before and 3 months after treatments. Additionally, twenty healthy volunteers also served as a control group for the evaluation of such parameters in basic condition. Results. Totally, 32 patients (group I, n = 18; group II, n = 14) completed the clinical study and were incorporated into the statistics. MDA level was higher and SOD activity and TAC were lower in patients compared to healthy individuals. After 3 months, TPOAb titer significantly decreased within group I (P<0.001) but did not change within group II (P=0.001). There were also no statistically significant changes in TSH and TgAb titers within the two groups (all P>0.05). Additionally, decreased MDA level (from 6.8 ± 1.3 nmol/ml to 4.9 ± 0.7 nmol/ml; P<0.001) and increased TAC (from 10.0 ± 1.9 mmol/l to 12.9 ± 3.1 mmol/l; P=0.003) and SOD activity (from 72.3 ± 10.3 U/ml to 84.3 ± 13.2 U/ml; P=0.007) were simultaneously observed after 3 months’ selenium treatment. Moreover, there was a negative correlation between TAC and TgAb/TPOAb and a positive correlation between MDA and TgAb/TPOAb in AIT patients. Conclusions. Our findings support the hypothesis that selenium treatment could decrease TPOAb titer via enforcing the defense against oxidative stress in euthyroid patients with AIT, which may be a potential underlying mechanism.

Abstract The haemato-biochemical indices and oxidative stress markers in horses naturally infected with Trypanosoma evansi were evaluated by analyzing the level of these parameters between T. evansi infected (microscopically positive patent group and PCR positive latent group) and infection free horses. To compare the hemato-biochemical indices and oxidative stress indicators, horses were divided into three categories based on diagnostic test employed and positive results obtained. These included Romanowsky stained slide positive group (Group I; n = 6), PCR positive group (group II; n = 28) and negative control group (group III, n = 30), revealing parasitologically positive patent, molecular positive latent and disease free status of horses. A significant reductions in total erythrocytes count (TEC, P = 0.01), haemoglobin (Hb, P = 0.01) and packed cell volume (PCV, P = 0.04) was noticed both in group I and group II while significant neutrophilia and lymphocytopenia was observed in group I when compared to negative control group. Substantial increase in creatinine (CRTN, P = 0.032) and gamma glutamyl transferase (GGT, P = 0.012) in group I while significant decrease in glucose (GLU, P = 0.04) and iron (Fe, P = 0.01) were noticed in both group I and group II in comparison to group III. A significant difference in lipid peroxides (LPO, P = 0.01) with highest level in patent group I (15.33 ± 0.53) followed by PCR positive latent group (14.09 ± 1.66) indicates higher lipid peroxidation in erythrocytes and oxidative stress in decreasing order when compared with infection free control horses (9.83 ± 0.97). Catalase (CAT, P = 0.01) was significantly lower in parasitological (0.82 ± 0.14) and molecular positive cases (1.27 ± 0.35) in comparison to control group (3.43 ± 0.96). The levels of superoxide dismutase (SOD, P = 0.01), reduced glutathione (GSH, P = 0.01) and ferric reducing antioxidant power (FRAP, P = 0.01) were significantly lower in parasito-molecular positive cases as compared to infection free control horses. An inverse correlation of RBC count with LPO and GSH and a direct correlation with catalase, SOD and FRAP was revealed. Overall, the observed substantial decreases in the oxidative parameters like catalase CAT, SOD, GSH and FRAP activities with remarkably elevated levels of LPO indicate high exposure of erythrocytes to oxidative damage in T.evansi infected horses.
