Background: A study was conducted to evaluate the antioxidant and immunological profile of methanolic extract of Adhatoda vasica leaves (AVE) in naturally infected sheep with gastrointestinal nematodes and compared with commonly used anthelmintic albendazole in sheep. Methods: Fifty four sheep found positive for gastrointestinal nematodes were divided into 3 equal groups, GI (infected-untreated: control), GII (infected- AVE treated) and GIII (infected- albendazole treated). Blood samples were drawn on 5th and 14th day after treatment for analysis of oxidative stress markers such as TBARS, TAC, SOD and catalase and immunological parameters such as total immunoglobulin, IgG and IL-10. Result: Helminthiasis in sheep cause a considerable oxidative stress. The anthelmintic activity of Adhatoda vasica surpassed the conventional synthetic drug albendazole in sheep in terms of oxidative and immunological changes in blood.

Forty-eight goats naturally infected with gastrointestinal nematodes were randomly divided into four groups (n=12): negative control (G1) (untreated), positive control (G2) (treated with doramectin, 1 mL/50 Kg b.w.), and G3 and G4 treated with 2.5 and 5 mg/Kg b.w. of a leaf aqueous extract ofCaesalpinia pyramidalis(CP). Fecal and blood samples were regularly collected for the evaluation of fecal egg count (FEC), hematological and immunological parameters to assess the anthelmintic activity. In treated animals with CP, there was noted a significant reduction of 54.6 and 71.2% in the mean FEC (P<0.05). An increase in IgA levels was observed in G3 and G4 (P<0.05), during the experimental period, suggesting that it was stimulated by the extract administration. In conclusion, the results showed that CP provoked a protective response in infected animals treated with them. This response could be partly explained by the CP chemical composition.

Introduction: The pathogenesis of Parkinson’s disease (PD) is multifactorial in which oxidative stress, neuroinflammation, and mitochondrial dysfunction are the leading factors. Currently, the antioxidant and anti-inflammatory agents of natural sources as neuroprotectants have raised much attention. The current study aimed to explore the neuroprotective effect of methanolic extract of Sargassum wightii in male Wistar albino rats against rotenone-induced PD. Methods: The rats were administered with rotenone (10 mg/kg orally) daily for 28 days to induce PD. S. wightii (200 mg/kg and 400 mg/kg) and levodopa+carbidopa combination (10 mg/kg) were administered to different groups of rats one hour prior to rotenone for 28 days. Behavioral parameters (akinesia, tremor, motor coordination, and locomotor activities) and body weight were recorded on days 14th and 28th of drug treatment. On the 28th day, the animals were sacrificed for the neurobiochemical analyses of brain tissue. Results: Rotenone treatment caused a significant reduction in behavioural parameters (P < 0.001), neurochemical deficits (P < 0.001), and elevation of oxidative stress markers (P < 0.001) in the brain. Pre-treatment with S. wightii at 200 mg/kg and 400 mg/kg doses significantly attenuated the rotenone-induced behavioral alterations and restored the mitochondrial NADH dehydrogenase activity and dopamine level in the striatum (P < 0.001). Moreover, 400 mg/kg of S. wightii restored the rotenone-induced increased oxidative stress markers like malondialdehyde (MDA), superoxide dismutase (SOD), and reduced glutathione (GSH) in the striatum (P < 0.01). Conclusion: S. wightii has provided a neuroprotective effect, probably by virtue of its antioxidant and dopamine restoring potential. Hence, it may offer a promising and new therapeutic lead for the treatment of PD but needs further research.

Immunological Changes

Stress is known to precipitate neuropsychiatric diseases, and depending upon its nature and intensity it can also influence the functioning of the immune system. Melatonin (N-acetyl-5-methoxy tryptamine) a pineal gland hormone and potent antioxidant is known to protect against many diseases. Effect of melatonin in stress-induced neuro-immunomodulation is not well elucidated. Therefore in the present study, the protective effects of melatonin were evaluated in restraint stress (RS)-induced behavioral and immunological changes in rats. RS for 1 h significantly reduces (i) percentage of open-arm entries and (ii) percentage of time spent on open-arm in elevated plus maze (EPM) test parameters (p < 0.01) and significant increase in MDA levels in brain homogenate when compared to non-RS control groups (p < 0.05). In immunological studies, both humoral and cell-mediated immune responses to antigen were significantly suppressed by RS for 1 h for 5 consecutive days, as evidenced by significant reduction in (i) anti-SRBC antibody titre, (ii) PFC counts, (iii) percentage change in paw volume, and (iv) Th1 (IFN-γ) and Th2 (IL-4) cytokine levels (p < 0.001 in all parameters). These RS-induced immunological changes were associated with significantly increased lipid peroxidation (MDA) levels in serum and significantly decreased activity of (i) SOD, (ii) CAT, and (iii) GSH levels in RS (X5)-exposed group (p < 0.02). Pretreatment with melatonin (10, 50, and 100 mg/kg) significantly reversed these RS-induced changes in EPM test parameters and humoral and cell-mediated immunological parameters, as well as oxidative stress markers in a dose-dependent manner by differential degrees (p < 0.001). Results are strongly suggestive of the involvement of free radicals during stress-induced neurobehavioral and immunological changes. These changes were significantly restored by melatonin pretreatment. We can conclude that melatonin may have a protective role during such stress-induced neuro-immunomodulation.

Background: Oxygen is involved in a variety of physiological reactions in aerobic organisms, such as those produced in the electron transport chain, hydroxylation, and oxygenation. Reactive oxygen species (ROS) are naturally formed as byproducts from these previously reactions involving the O2 molecule; they are made up of superoxide anion (O2−), hydroxyl radical (HO−), hydrogen peroxide (H2O2), nitric oxide (NO), peroxyl (ROO−), and reactive aldehyde (ROCH). Under certain environmental stress conditions, ROS are accumulated causing cellular damage but also triggering the overexpression of several enzyme classes such as superoxide dismutases (SOD), catalases (CAT) and glutathione peroxidases (GPx), which represent an important intrinsic antioxidant defence line. Liver is a key organ in vertebrates including farm animals and human. The oxidative stress plays an important role in systemic malfunctions including hepatic, renal and immunological, disorders. Methods: This review presents a brief update about the relationship of oxidative stress with hepatic, renal and immunological malfunctions in stressed organisms. Cellular and exogenous hepatoprotective compounds share also the ability to scavenge ROS acting as antioxidants and in many cases as stimulators of immune response in stressed organisms. We present the effect of some hepatoprotectors on the hepatic, renal and immunological function in stressed mice by the jointed evaluation of biological and oxidative stress markers. Conclusion: Hepatoprotective effect of several exogenous compounds is very associated with their antioxidant capacity. This fact is relevant for keeping oxidant/antioxidant balance in the respective organs, but also for maintaining the physiological status of the whole organism.

Background: One of the most common complications of pregnant women is gestational diabetes mellitus (GDM). Oxidative stress can play an important role in GDM. Objective: The aim of this study was to evaluate salivary antioxidants and oxidative stress markers in GDM. Method: Twenty pregnant women with GDM and 20 healthy pregnant women with normal blood glucose test participated in this study. Five mL of unstimulated saliva samples were collected. Spectrophotometric assay was carried out for sialochemical analysis. Stata software was used for data analysis. Results: The GDM group exhibited no significant difference in salivary total antioxidant capacity and malondialdehyde compared to the healthy control group. All of antioxidants markers, the uric acid, total antioxidant, peroxidase and catalase, decreased in GDM group that the difference of peroxidase and catalase was statistically significant. All of oxidative stress markers, the salivary malondyaldehid, total oxidative stress and total thiol, increased in GDM group. GDM group exhibited significantly higher salivary total oxidative stress levels. Conclusion: Catalase level was significantly lower and total oxidative stress was significantly higher. These two markers might have significant importance and might exhibit early changes compared to other factors in GDM. . Some of salivary antioxidants might have diagnostic, prognostic or therapeutic implications in GDM. Other studies with large sample size on salivary and blood samples need to be done to confirm this properties and salivary samples using instead of blood samples in GDM biomarkers changes.

Background: An imbalance between pro-oxidants and antioxidants determines the level of oxidative stress which is implicated in the etiopathogenesis of various neuropsychiatric disorders including depression. Therefore, treatment with antioxidants could potentially improve the balance between pro-oxidants and antioxidants. Objective: The objective of this study was to evaluate the ability of astaxanthin, a potential antioxidant, to reduce reserpine-induced depression in BALB/c mice (Mus musculus). Methods: On the behavioral level, antidepressant property of astaxanthin (50 mg/kg, orally) on reserpine (2 mg/kg, subcutaneously) induced depressed mice was evaluated by Forced Swim Test (FST) and Tail Suspension Test (TST). In the biochemical level, the ability of astaxanthin to mitigate reserpine-induced oxidative stress was evaluated by the measurement of Malondialdehyde (MDA) and nitric oxide (NO) in brain, liver and plasma samples. On the other hand, the efficiency of astaxanthin to replenish glutathione depletion and antioxidant enzyme activity augmentation in the same samples were also investigated. Results: Astaxanthin was able to lower reserpine induced immobility time significantly (p<0.05) in FST and TST. Mice treated with astaxanthin showed significantly (p<0.05) low level of oxidative stress markers such as Malondialdehyde (MDA), Nitric Oxide (NO). Consistently, the level of reduced Glutathione (GSH), and the activity of Superoxide Dismutase (SOD) and catalase were augmented due to the oral administration of astaxanthin. Conclusion: This study suggests that astaxanthin reduces reserpine-induced oxidative stress and therefore might be effective in treating oxidative stress associated depression.
