Objectives: Aluminum phosphide (AIP) is the commonly used pesticide in agriculture, which induces oxidative stress in almost all major body systems and organs. The aim of this study was to evaluate the efficacy of nanocurcumin and curcumin on serum oxidative stress level in subacute toxicity with AIP. Materials and Methods: In this study 36 male Wistar rats (220-250 g) were randomly divided into six groups. Control (C) receiving normal saline; group AIPreceiving AIP (2 mg/kg daily); group Cur receiving curcumin (100 mg/kg daily); group Nano-cur receiving nanocurcumin (100 mg/kg daily); group AIP+ Cur receiving AIP (2 mg/kg daily) and curcumin (100 mg/kg daily); and group AIP and Nano-cur receiving AIP (2 mg/kg daily) and nanocurcumin (100 mg/kg daily). Serum total antioxidant capacity (TAC), lipid peroxidation (LPO), total thiol groups (TTG), and catalase (CAT) activity were measured. Results: AIP administration led to a significant increase in LPO, and decreased the CAT activity, TAC, and TTG compared to the control group (P<0.05). Curcumin and nanocurcumin caused a significant decrease in the levels of LPO compared to the AIP-exposed groups (P<0.05). Moreover, in the nanocurcumin-treated groups, compared to a poisoned group, TAC and TTG increased significantly (P<0.01). There were no significant changes in CAT activity improvement. Conclusion: Nanocurcumin and curcumin improved the AIP-induced oxidative damage.

Background: There is a well-documented cross-talk between the gut and brain. Evidence is accumulating to suggest beneficial effects of psychobiotics [prebiotics, probiotics or synbiotics] on psychological distress in disease states. However, their role in healthy status remains relatively unclear. Objectives: The present study was aimed to clarify if psychobiotics could influence behavioral responses and physiological stress in healthy rats. Methods: In the present experiment, 28 male Wistar rats were divided into four groups (healthy rats treated by Lactobacillus plantarum (L.plantarum), inulin and their combination (synbiotic) and control group). Then, psychobiotics were administered to the intervention groups for 8 weeks. Behavioral tests (Morris water maze, Elevated plus maze, and Forced swimming test) were performed at the endpoint. Then, serum and brain levels of superoxide dismutase, malondialdehyde, glutathione peroxidase, total antioxidant capacity, brain-derived neurotrophic factor (BDNF), and serotonin were measured. Results: Our finding indicated that unlike inulin, the administration of L.plantarum and synbiotic could ameliorate depression and anxiety-like behavior and cognitive performance (P<0.05). Serum and brain oxidative stress markers were significantly improved by synbiotic consumption. Intake of L.plantarum led to decreased oxidative stress in the hippocampus and amygdala (P<0.05). Moreover, a significant increase in hippocampal serotonin and BDNF concentration was observed after synbiotic and L.plantarum intake (P<0.05). In addition, there was a strong correlation of serum and brain markers with behavioral performance (P< 0.05). Conclusion: Our study suggests that psychobiotics therapy may have favorable effects on the amelioration of psychological disorders.

Background: The activation of Nrf2/HO-1 pathway has been shown to protect against cisplatin- induced nephrotoxicity by reducing oxidative stress. Berberine (Ber), an isoquinoline alkaloid, has demonstrated antioxidant, anti-inflammatory and anti-apoptotic activities in various experimental models. Aim: To check the effect of Ber on cisplatin-induced nephrotoxicity and to explore the involved mechanism. Methods: Adult male Wistar rats were divided into 6 groups: Normal, cisplatin-control, treatment groups and per se group. Normal saline and Ber (20, 40 and 80 mg/kg; p.o.) was administered to rats for 10 days. A single intraperitoneal injection of cisplatin (8 mg/kg) was injected on 7th day to induced nephrotoxicity. On 10th day, rats were sacrificed, the kidney was removed and stored for the estimation of various parameters. Results: As compared to cisplatin-control group, Ber pretreatment improved renal function system and preserved renal architecture. It also diminished oxidative stress by upregulating the expression of Nrf2/HO-1 proteins. In addition, Ber attenuated the cisplatin mediated inflammation and apoptosis. Furthermore, it also reduced the phosphorylation of p38/JNK and PARP/Beclin-1 expression in the kidney. Conclusion: Ber attenuated renal injury by activating Nrf2/HO-1 and inhibiting JNK/p38MAPKs/ PARP/Beclin-1 expression which prevented oxidative stress, inflammation, apoptosis and autophagy in renal tissue.

Abstract Blast lung injury (BLI) is the major cause of death in explosion-derived shock waves; however, the mechanisms of BLI are not well understood. To identify the time-dependent manner of BLI, a model of lung injury of rats induced by shock waves was established by a fuel air explosive. The model was evaluated by hematoxylin and eosin staining and pathological score. The inflammation and oxidative stress of lung injury were also investigated. The pathological scores of rats’ lung injury at 2 h, 24 h, 3 days, and 7 days post-blast were 9.75±2.96, 13.00±1.85, 8.50±1.51, and 4.00±1.41, respectively, which were significantly increased compared with those in the control group (1.13±0.64; P&lt;0.05). The respiratory frequency and pause were increased significantly, while minute expiratory volume, inspiratory time, and inspiratory peak flow rate were decreased in a time-dependent manner at 2 and 24 h post-blast compared with those in the control group. In addition, the expressions of inflammatory factors such as interleukin (IL)-6, IL-8, FosB, and NF-κB were increased significantly at 2 h and peaked at 24 h, which gradually decreased after 3 days and returned to normal in 2 weeks. The levels of total antioxidant capacity, total superoxide dismutase, and glutathione peroxidase were significantly decreased 24 h after the shock wave blast. Conversely, the malondialdehyde level reached the peak at 24 h. These results indicated that inflammatory and oxidative stress induced by shock waves changed significantly in a time-dependent manner, which may be the important factors and novel therapeutic targets for the treatment of BLI.

To investigate the effect of B-ultrasound-guided nerve block on analgesia and sedation in patients with acute cholecystitis undergoing puncture and drainage. Methods 96 patients with acute cholecystitis who underwent puncture and drainage from May 2018 to November 2020 were randomly divided into control group and observation group by random number table method, with 48 cases in each group. The patients in the control group were anesthetized by local infiltration. The patients in the observation group were anesthetized by B-ultrasound-guided nerve block. Heart rate, blood pressure, analgesia score, sedation score, and oxidative stress level were compared between the two groups. Results At the time of puncture (T2), heart rate (HR) and mean arterial pressure (MAP) in the two groups were significantly lower than those before operation (T1) (P<0.05); at the end of operation (T3), HR and MAP in the control group were significantly higher than those at T1 (P<0.05); at T2, HR and MAP in the observation group were significantly higher than those in the control group (P<0.05); at T3, HR and MAP in the observation group were significantly lower than those in the control group (P<0.05). AtT2 and T3, Ramsay sedation score in both groups was significantly lower than that at T1 (P<0.05), while Ramsay score in the observation group was significantly higher than that in control group (P<0.05); atT2 and T3, visual analog scale (VAS) pain score in both groups was significantly higher than that at T1 (P<0.05), while VAS score in the observation group was significantly lower than that in the control group (P<0.05). After operation, the levels of serum malondialdehyde (MDA) and superoxide dismutase (SOD) in the two groups were significantly higher than those before operation (P<0.05), and the levels of serum total antioxidant capacity (T-AOC) were significantly lower than those before operation (P<0.05); after operation, the levels of serum SOD and T-AOC in the observation group were significantly higher than those in the control group (P<0.05), and the levels of MDA in the observation group were significantly lower than those in the control group (P>0.05). Conclusion B-ultrasound-guided nerve block anesthesia can maintain the stable hemodynamic index of patients with acute cholecystitis undergoing puncture and drainage therapy, improve the analgesic and sedative effect and reduce the oxidative stress response of the body.

Objective The present study aimed to assess the global oxidant and antioxidant status in infants born to preeclamptic mothers and their correlation with cardiac functions. Study Design We compared 40 infants born to preeclamptic mothers with 40 premature infants born to normotensive mothers. We assessed the relationship between echocardiographic measurements and total antioxidant capacity (TAC) and total oxidant status (TOS) values. Results In the study group, TAC, TOS, and oxidative stress index (OSI) levels were significantly higher in the cord blood (p = 0.03, 0.04, and 0.039, respectively) than in the control group. We did not observe any correlation between echocardiographic measurements and TAC, TOS, and OSI levels in infants born to preeclamptic mothers. Conclusion Compared with the control group, despite higher TAC levels in infants born to preeclamptic mothers, concurrent elevated OSI levels reveal that the oxidant–antioxidant balance is disturbed in favor of oxidants. Furthermore, the findings of this study suggest that echocardiographic parameters are unaffected by the oxidant status.

Oxidative stress is an imbalance between free radicals and antioxidants, and is an important etiological factor in the development of hypertension. Recent experimental evidence suggests that subpressor doses of angiotensin II elevate oxidative stress and blood pressure. We aimed to investigate the oxidative stress related mechanism by which a subpressor dose of angiotensin II induces hypertension in a normotensive rat model. Normotensive male Wistar rats were infused with a subpressor dose of angiotensin II for 28 days. The control group was sham operated and infused with saline only. Plasma angiotensin II and H2O2 levels, whole-blood glutathione peroxidase, and AT-1a, Cu/Zn SOD, and p22phox mRNA expression in the aorta was assessed. Systolic and diastolic blood pressures were elevated in the experimental group. There was no change in angiotensin II levels, but a significant increase in AT-1a mRNA expression was found in the experimental group. mRNA expression of p22phox was increased significantly and Cu/Zn SOD decreased significantly in the experimental group. There was no significant change to the H2O2 and GPx levels. Angiotensin II manipulates the free radical-antioxidant balance in the vasculature by selectively increasing O2− production and decreasing SOD activity and causes an oxidative stress induced elevation in blood pressure in the Wistar rat.

Background: Persistent up regulation of NF-&kappa;B leads to chronic inflammation and subsequent microglial activation and takes neurons towards death by activating death receptor domains and the p53 pathway. Thus, inhibition of NF-&kappa;B may lead to more effective treatment for Parkinson&rsquo;s disease. Therefore, we have used mangiferin, specific inhibitor of NF-&kappa;B in this study. Method: The study utilized male Wistar rats weighing 200-250 gm (n=8 in each group). Stereotactic surgery of rats was done to induce 6-OHDA lesioning in rats. On day 42, rats were subjected to behavioural studies to evaluate effect of mangiferin and their brains were taken out after euthanasia to perform biochemical and molecular studies. Results: Mangiferin significantly increases locomotor parameters in 6-OHDA lesioned rats. It also decreases activity of Cyclooxygenase enzyme which then leads to decrease concentration of inflammatory cytokines. Microglial inflammation was also substantially reduced by reducing MPO concentration. Oxidative stress burden was also reduced after treatment with mangiferin as indicated by increase in Total Antioxidant Capacity, SOD and Catalase and reduction in concentration of MDA. Treatment with mangiferin also reduces burden of oxidative stress by increasing the activity of NRF2/ARE pathway. Activity of Caspase 3 and 9 was also significantly reduced after treatment with mangiferin. Significant decrease in activity of both Cox1 and Cox 2 was also observed. Maximum improvement in all parameters was observed in rats treated with grouping of mangiferin 45mg.kg-1 and levodopa 10mg.kg-1. Treatment with levodopa alone has no significant effect on biochemical and molecular parameters though it significantly improves behavioural parameters. Conclusion and Implications: Results of this study suggest that mangiferin has protective effect in hemi-parkinsonian rats by inhibiting NF-&kappa;B. Current treatment of Parkinson&rsquo;s disease does not target the underlying problem of the disease. Therefore, combination therapy of mangiferin and levodopa can be helpful in better management of Parkison&rsquo;s.

Objective This study was carried out to investigate interval exercise on Smyd1 expression and F-actin sarcomere assembly in non-infarcted myocardium of normal and myocardial infarction(MI) rats and its possible mechanism. Methods Male SD rats were randomly divided into normal control group (C), normal interval exercise group (CE), sham-operated group (S), MI group (MI), MI with interval exercise group (ME) and MI with ROS Tempol group (MT), n=10. MI model was established by left anterior descending coronary artery ligation. Interval exercise was carried out on a small animal treadmill. MT group was given an oral solution of Tempol (2mmol/L). Hemodynamics was performed to evaluate cardiac function. HE and Masson staining were used to analyze the cross-sectional area (CSA) of cardiomyocytes and collagen volume fraction, respectively. T-SOD and MDA kits were used to detect oxidative stress. H9C2 cells were treated with H2O2. Immunofluorescence staining was used to determine Smyd1 expression and F-actin sarcomere assembly. RT-qPCR and Western blotting were used to detect the gene or protein expression of Smyd1, Trx1, Hsp90, MuRF1, cTnI, α-actinin and BNP. Results Smyd1, Trx1, Hsp90, MuRF1 and BNP expression in the peri-infarcted area were up-regulated, but cTnI and α-actinin expression and F-actin assembly were decreased. The cardiac function was reduced. Both interval exercise and Tempol intervention significantly increase the CSA and expression of Smyd1, Trx1, cTnI and α-actinin, improve the antioxidation capacity and F-actin sarcomere assembly and cardiac function, reduce the expression of Hsp90, MuRF1, BNP and ROS level, and inhibit the fibrosis of myocardium. The oxidative stress level was closely related to the Smyd1 expression. Improvement of cardiac function were correlated with Smyd1 expression. H2O2 can induce oxidative stress injuries of H9C2, and its closely related to cardiomyocytes oxidative stress level and Smyd1 expression. Conclusions Interval exercise could promote antioxidant capability and physiological cardiomyocyte hypertrophy, regulate the expression of Smyd1, Hsp90 and MuRF1 in infarcted heart; so as to improve the cardiac function. Smyd1 may participate in pathologic hypertrophy of cardiomyocytes caused by oxidative stress.
