Objective: The objective of this study was to evaluate the protective effect of Hemidesmus indicus against 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mice model. Methods: A total of 18 male Swiss Albino mice were divided into three groups (n=6). Hydroalcoholic concentrate of H. indicus (HAHI) at 200 and 400 mg/kg dosages, 30 min before the MPTP (20 mg/kg, intraperitoneal organization) treatment, was regulated for 7 days, and behavioral assessment was made by rotarod test, grip strength test, locomotor activity, and catatonia behavioral study. Appraisal of cell reinforcement catalysts, such as thiobarbituric acid reactive substance (TBARS), superoxide dismutase, catalepsy, glutathione (GSH) peroxidase, and GSH, were also assessed to screen the neurotoxicity incited by MPTP. Results: In the present investigation, the neuroprotective impacts of the hydroalcoholic concentrate of H. indicus were assessed, Which is known for its monoamine oxidiase activity, stimulant, anti-convulsant activity and a section of it is used as nerve tonic Frozen at 8 degree C. The cell viability analysis and IC50 determination in SH-SY5Y neuroblastoma cell lines were performed by MTT assay, and neuronal red uptake assay and HAHI were found to have a significant IC50 value in SH-SY5Y cells. Conclusion: The outcomes demonstrated that HAHI essentially enhanced the behavioral studies, striatal neurotransmitter content, and antioxidant status in a dose-dependent manner lessened TBARS level.

The cytotoxic effect of chlorpyrifos (CP) on human HepG2 cell lines and the protective role of melatonin were investigated. TD50 of CP for HepG2 cells was also determined. The viability of HepG2 cells decreased with CP treatment in a dose-dependent manner (P <0.05). Preincubation with melatonin prior to CP application caused an increase in cell viability (P <0.05). TD50 of CP for HepG2 was determined as 84.5 μg/mL. A 1-hour melatonin treatment caused a decrease in TD50 from 84.5 to 34.1 μg/mL. The level of thiobarbituric acid reactive substance (TBARS) and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) were determined in cell lines with or without melatonin administration to find out the possible mechanism of melatonin. CP caused a significant decrease in SOD, GSH-Px and CAT activities and an increase in TBARS level (P <0.05). Pre-incubation of cells with melatonin prevented an increase in TBARS. Melatonin also reduced the CP-caused inhibition of the activities of GSH-Px and CAT (P <0.05). It was suggested that CP shows a cytotoxic effect on HepG2 cell lines and melatonin can suppress cytotoxicity caused by CP with its antioxidant properties. Melatonin also reduces TD50 of CP for HepG2 cell lines.

Resistance of erythrocytes from Brown trout (Salmo trutta m. trutta L.) affected by ulcerative dermal necrosis syndrome In the present work we evaluated the effect of ulcerative dermal necrosis (UDN) syndrome on resistance of erythrocytes to haemolytic agents and lipid peroxidation level in the blood from brown trout (Salmo trutta m. trutta L.). Results showed that lipid peroxidation increased in erythrocytes, as evidenced by high thiobarbituric acid reactive substance (TBARS) levels. Compared to control group, the resistance of erythrocytes to haemolytic agents was significantly lower in UDN-positive fish. Besides, UDN increased the percent of hemolysated erythrocytes subjected to the hydrochloric acid, urea and hydrogen peroxide. Results showed that UDN led to an oxidative stress in erythrocytes able to induce enhanced lipid peroxidation level, as suggested by TBARS level and decrease of erythrocytes resistance to haemolytic agents.

The aim of the study is protective effect of compound Eclipta alba and Ocimum sanctum on Parkinsonism induced mice by haloperidol injection. Parkinsonism is neurodegenerative disease due to the deficiency of dopamine in brain. The pathological hallmark of Parkinson’s disease in the cell loss within substantia nigra pars compacta (SNpc) region and the disease is charactrised by bradykinesia, rigidity, postural instability, orofacial dyskinesia, muscular stiffness and tremor1. Mice were injected 1mg/kg haloperidol and then treated with test and standard substance for 15 days. The impairment in catatonia in mice were tested using catatonic activity. Biochemical analysis of brain homogenate was performed so ass to assess brain Thiobarbituric acid reactive substance (TBARS) level and reduced glutathione (GSH) and TNF-α level were measured to assess total oxidative stress. EA 300mg/kg and OS 400mg/kg show slightly change in catatonic activity in mice while EA 600mg/kg and 800mg/kg significantly change in catatonic activity. Furthermore, Eclipta alba and Ocimum sanctum prevent the haloperidol induced changes in the level of brain TBARS, GSH and TNF-α. From the results we conclude that Eclipta alba and Ocimum sanctum has protective action against impairment in catatonic activity and pathological damage due to oxidative stress induced by intraperitoneally injection of haloperidol in mice.        Keywords: Eclipta alba, Ocimum Sanctum, Parkinsonism, Anti-oxidant.

Wen-Pi-Tang is a Chinese prescription used traditionally as a medicine to treat moderate renal failure. In this study, we used rats subjected to subtotal nephrectomy and streptozotocin injection to examine the effects of Wen-Pi-Tang on diabetic nephropathy. Wen-Pi-Tang was administered at a dose of 50, 100 or 200 mg/kg body weight/day for 15 weeks. Diabetic nephropathy is one of the most serious chronic complications of diabetes mellitus, and renal dysfunction is reflected by proteinuria, decreased creatinine clearance (Ccr) and increased serum urea nitrogen and creatinine (Cr) levels. Wen-Pi-Tang treatment for 15 weeks resulted in significant reductions of blood glucose and serum urea nitrogen levels, while proteinuria, Ccr and serum Cr levels did not change significantly. Wen-Pi-Tang also lowered serum triglyceride and thiobarbituric acid-reactive substance levels in a dose-dependent manner. Furthermore, the disorders of the glucose-dependent metabolic pathway due to this pathological condition were normalized by the administration of Wen-Pi-Tang through decreased formation of advanced glycation end-products in the kidney. Wen-Pi-Tang protected against the development of renal lesions, glomerular sclerosis and mesangial matrix expansion, assessed by histopathological evaluation and scoring. This study suggests that Wen-Pi-Tang treatment could be beneficial in reducing the risk of developing diabetic nephropathy.

The effect of α-tocopherol supplementation on adaptation to training is still equivocal. The aim of the study was to determine the effect of training and α-tocopherol supplementation on α-tocopherol and thiobarbituric acid reactive substance (TBARS) concentration in the rat liver, heart, muscles, and testes. Male Wistar rats (n=32) were divided into four groups (nonsupplemented, not trained—C; nonsupplemented, trained—CT; supplemented, not trained—E; supplemented and trained—ET). During the 14-day experimental period, 2 mg/d of vitamin E as α-tocopherol acetate was administered to the animals (groups E and ET). Rats in the training group (CT and ET) were subjected to 15 minutes of treadmill running each day. The α-tocopherol levels in rat tissues were assessed using high-performance liquid chromatography (HPLC). Lipid peroxides were determined by TBARS spectrophotometric method. α-Tocopherol had a significant impact on α-tocopherol concentration in all tissues. Training increased the α-tocopherol concentration in the heart and muscles but reduced it in the liver. Training also caused increased lipid peroxidation in the muscles, heart, and testes; but a higher α-tocopherol content in tissues reduced the TBARS level. The main finding of the study is that impaired α-tocopherol status and its adequate intake is needed to maintain optimal status to prevent damage to the skeletal and cardiac muscles as well as the testes in growing individuals.

The experiment was conducted to assess the antioxidant efficacy of clove extract (CE) in surimi from silver carp during -1°C storage. CE was added to surimi at 0.5%, 1.0%, and 1.5% (w/w) further determined its antioxidant efficacy. Compared with control (without antioxidants), CE treatments significantly decreased the thiobarbituric acid reactive substance (TBARS values), a*-value, and total carbonyls content, reduced the total sulfhydryl loss of surimi in a dose-dependent manner (P < 0.05), and both ATPase activity increased with the increasing of the storage time (P < 0.05).The results suggested the positive effect of CE to retard lipid and protein oxidation and discoloration of surimi, and its potential use as natural antioxidants in fish products.

Abstract Objectives The study has been commenced to discover the potential of Phlorizin (dual SGLT inhibitor) in streptozotocin induced dementia of Alzheimer’s disease (AD) type. Material and methods Injection of Streptozotocin (STZ) was given via i.c.v. route (3 mg/kg) to induce dementia of Alzheimer’s type. In these animals learning and memory was evaluated using Morris water maze (MWM) test. Glutathione (GSH) and thiobarbituric acid reactive species (TBARS) level was quantified to evaluate the oxidative stress; cholinergic activity of brain was estimated in term of acetylcholinesterase (AChE) activity; and the levels of myeloperoxidase (MPO) were measured as inflammation marker. Results The mice model had decreased performance in MWM, representing impairment of cognitive functions. Biochemical evaluation showed rise in TBARS level, MPO and AChE activity, and fall in GSH level. The histopathological study revealed severe infiltration of neutrophils. In the study, Phlorizin/Donepezil (serving as positive control) treatment mitigate streptozotocin induced cognitive decline, histopathological changes and biochemical alterations. Conclusions The results suggest that Phlorizin decreased cognitive function via its anticholinesterase, antioxidative, antiinflammatory effects and probably through SGLT inhibitory action. It can be conferred that SGLTs can be an encouraging target for the treatment of dementia of AD.

Background: Exogenous antioxidants are considered as a promising therapeutic approach to treat neurodegenerative diseases since they could prevent and/or minimize the neuronal damage by oxidation. Objective: Three series of lipophilic compounds structurally based on scutellarein (2), which is one metabolite of scutellarin (1) in vivo, have been designed and synthesized. Methods: Their antioxidant activity was evaluated by detecting the 2-thiobarbituric acid reactive substance (TBARS) produced in the ferrous salt/ascorbate-induced autoxidation of lipids, which were present in microsomal membranes of rat hepatocytes. The lipophilicity of these compounds indicated as partition coefficient between n-octanol and buffer was investigated by ultraviolet (UV) spectrophotometer. Results: This study indicated that compound 5e which had a benzyl group substituted at the C4'- OH position showed a potent antioxidant activity and good lipophilicity. Conclusion: 5e could be an effective candidate for preventing or reducing the oxidative status associated with the neurodegenerative processes.

ABSTRACTThis study investigated the pathophysiological role of GRP78 in the survival of lung cancer cells. Lung cancer patient data from public databases were used to analyze the expression of GRP78 and its influence on prognoses. In vivo, GRP78 protein expression was analyzed in an established urethane-induced lung tumor mouse model. In vitro, the effects of targeted inhibition of GRP78 by HA15 in lung cancer cells were assessed, with cell viability analyzed using a CCK-8 assay, cell proliferation using an EdU assay, apoptosis and cell cycle using flow cytometry, subcellular structure using electron microscopy, and relative mRNA and protein expression using RT-PCR, western blotting or immunofluorescence assays. The results showed that GRP78 was highly expressed in the lung tissue of lung cancer mice model or patients, and was associated with a poor prognosis. After inhibition of GRP78 in lung cancer cells by HA15, cell viability was decreased in a dose- and time-dependent manner, proliferation was suppressed and apoptosis promoted. Unfolded protein response signaling pathway proteins were activated, and the autophagy-related proteins and mRNAs were upregulated. Therefore, targeted inhibition of GRP78 by HA15 promotes apoptosis of lung cancer cells accompanied by ER stress and autophagy.
