The study was designed to investigate the antioxidant and antitoxicological potential of                    Sesamum indicum Linn seed (benni seed) oil on hypercholesterolemic rat. Albino rats weighing between 120-130 g were divided into two groups, group 1, was fed with normal rat diet(normal control), groups 2 was fed 1% cholesterol and 20% soya bean oil for 3 weeks to induce hypercholesterolemic state. Group 2 was later divided into groups 2, 3 and 4, group 2 was untreated, groups 3 and 4 were later fed with 5% and 10% Sesamum indicum L. seed oil incorporated in normal rat diet for another 6 weeks respectively. Significant (P<0.05) increase in lipid peroxidation (TBARs) and reduction in superoxide dismutate (SOD) and catalase (CAT) was observed in the liver of the hypercholesterolemic rats as compared to the normal control. At the same time, the oxidative stress causes significant (P<0.05) increase in serum level of Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) and Alkaline phosphatase (ALP) of hypercholesterolemic rats. Administering Sesamum indicum Linn seed oil significantly reduced (P<0.05), serum ALT, AST, ALP and lipid peroxidation, elevated the level of SOD and CAT in the liver of Sesamum oil treated hypercholesterolemic rats. These findings indicate that Sesamum indicum Linn seed oil show possible prevention of hepatic stress by high cholesterol and free radical mediated oxidative stress in cells of experimental hypercholesterolemic rats.

Background: Oxidative stress is the major mechanism of action employed by many drugs, xenobiotics and toxicants that generate reactive metabolites in the body to elicit adverse reactions when there are insufficient antioxidants to neutralise the excess reactive metabolites. Objectives: This study evaluated antioxidant compositions and antioxidative activities of ethanol extract of Alstonia boonei stem bark with the view of understanding its ameliorative potentials on oxidative stress. Materials and Methods: Thirty-six rats divided into 6 groups of 6 rats each was used for this study. Group 1 served as normal control, group 2-6 were carbon tetrachloride-induced oxidative stress which served as treatment groups. Group 2 was untreated, group 3 was treated with silymarin (100 mg/kg) while group 4-6 were treated with the extract 100, 200 and 500 mg/kg body-weight for 28 days respectively. The animal study and antioxidant compositions of the extract were analysed using standard methods. Results: The extract was found to rich in antioxidant components such as phenols, flavonoids, β-carotene and lycopene. The extract showed high DPPH (2, 2-diphenyl-1-picrylhydrazyl) and nitric oxide radical scavenging activities and high ferric reducing antioxidant power with increasing concentrations. The significant (P < 0.05) reduction in antioxidant enzymes activities and increased level of lipid peroxidation caused by the carbon tetrachloride induction were significantly (P < 0.05) reversed, in the extract-treated groups relative to the normal control. Conclusions: These findings suggest that the extract possesses antioxidative properties and can be used in the management of oxidative stress and its related disease conditions.

Protective Effects

The aim of the present study was to investigate the protective effects of Sesbania grandiflora flower (SGF) extract on erythrocyte membrane in Streptozotocin (STZ)-induced diabetic rats. Adult male albino rats of Wistar strain, weighing 190–220 g, were made diabetic by an intraperitonial administration of STZ (45 mg/kg). Normal and diabetic rats were treated with SGF, and diabetic rats were also treated with glibenclamide as drug control, for 45 days. In this study plasma insulin and haemoglobin levels were decreased and blood glucose, glycosylated haemoglobin, protein oxidation, lipid peroxidation markers, and osmotic fragility levels were increased in diabetic rats. Moreover, erythrocytes antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxide, glutathione reductase, glutathione-S-transferase, and glucose-6-phosphate dehydrogenase activities and non-enzymatic antioxidants such as vitamin C, vitamin E, reduced glutathione (GSH), and oxidized glutathione (GSSG) levels were altered. Similarly, the activities of total ATPases, Na+/K+-ATPase, Ca2+-ATPase, and Mg2+-ATPase were also decreased in the erythrocytes of diabetic rats. Administration of SGF to STZ-induced diabetic rats reduced blood glucose and glycosylated haemoglobin levels with increased levels of insulin and haemoglobin. Moreover, SGF reversed the protein and lipid peroxidation markers, osmotic fragility, membrane-bound ATPases activities, and antioxidant status in STZ-induced diabetic rats. These results suggest that SGF could provide a protective effect on diabetes by decreasing oxidative stress-associated diabetic complications.

Aim: In cyclosporin-A (CsA)-induced toxicity, oxidative stress has been implicated as a potential responsible mechanism. Therefore, we aimed to investigate the protective role of erdosteine against CsA-induced nephrotoxicity in terms of tissue oxidant/antioxidant parameters and light microscopy in rats. Materials and methods: Wistar albino rats were randomly separated into four groups. Group 1 rats treated with sodium chloride served as the control, group 2 rats were treated with CsA, group 3 with CsA plus erdosteine, and group 4 with erdosteine alone. Animals were killed and blood samples were analyzed for blood urea nitrogen (BUN), serum creatinine (Cr), uric acid (UA), total protein (TP), and albumin (ALB) levels. Kidney sections were analyzed for malondialdehyde (MDA) and nitric oxide (NO) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities, as well as for histopathological changes. Results: In the CsA group, MDA, GSH-Px, BUN, and Cr levels were increased. The TP and ALB levels were decreased. These changes had been improved by erdosteine administration. Other biochemical parameters did not show any significant change. Conclusion: These results indicate that erdosteine produces a protective mechanism against CsA-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

The objective of the present study was to evaluate nephroprotective activity of Amomum subulatum seed extract against Cypermethrin induced nephrotoxicity in albino rats. The animals were divided into five different groups consisting of six rats each. Except normal control and test drug alone group, all the rats were treated with Cypermethrin 25g/kg body weight orally for 28 consecutive days and test group IV & V (ASSE 200 & 400mg/kg body weight) were co administered with Cypermethrin orally for 28 consecutive days. On the 28th haematalogical, biochemical and histopathalogical parameters were estimated. The chronic administration of Cypermethrin caused significant elevation in the serum creatinine and urea level and increased lipid peroxidation in the kidney tissue homogenate as compared to normal control. The histological examination of kidney tissues revealed mild fatty changes especially in the sub capsular region in sections, dilatation of glomerulus along with obliteration of periglomerular space and shrinkage of glomerulus was observed. The co administration of test drug significantly attenuated the Cypermethrin induced elevated serum urea and creatinine and lipid peroxidation in tissue homogenate. Thus we can conclude the Amomum subulatum seed extract has significant nephroprotective effect and reversed Cypermethrin induced nephrotoxicity.

Diabetes mellitus is a serious chronic disease in which the oxidant-antioxidant balance is impaired, causing many complications, including hepatopathy. In this study, the effects of short-term and low-dose N-acetylcysteine (NAC) administration on the biochemical, proinflammatory, and oxidative stress parameters in the liver tissue of diabetic rats were investigated. Twenty-four adult male Wistar albino rats weighing approximately 250–300 g were divided into 4 groups (n = 6): Control, Streptozotosin (STZ)-induced diabetes (DM), NAC treatment (60 mg/kg), and STZ-induced diabetes treated with NAC (DM+NAC; 60 mg/kg). NAC treatment was administered intraperitoneally as a single daily dose for 7 days. At the end of the experiment (3 weeks), blood and liver samples were collected for biochemical parameter analysis. Lipid peroxidation, antioxidant parameters, and nitric oxide (NOx) levels were determined by spectrophotometric method. Tissue inflammation parameters were evaluated by ELISA. Lipid peroxidation, proinflammatory cytokines, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values increased significantly with diabetes. NAC treatment significantly decreased serum ALT and AST levels and proinflammatory cytokines in the diabetic group. Liver glutathione (GSH) and NOx levels increased significantly in the DM+NAC group ( p < 0.05). While NAC treatment reduced lipid peroxidation in the liver, it improved the inflammatory response and antioxidant status. The beneficial effect of NAC treatment may be due to its antioxidant activity and the resulting increased level of GSH. The results show that low-dose and short-term NAC treatment had a positive effect on oxidative damage and inflammation in liver tissue. NAC can be used as a potential antioxidant in diabetes to prevent hepatopathy.

Many species of Ocimum possess anti -inflammatory, antioxidant and anti -microbial properties and the plants are widely used in Ayurveda. The oxidative stress induced by ethanol consumption had been implicated the changes in the structure and functions of liver cells especially the membrane phospholipids leading to lipid peroxidation. This study was to assess the curative potential of the methanol extract of two different species of Ocimum , O. canum and O. gratissimum on alcohol induced hepatotoxicity in albino rats. Male Wister rats of body weight 200- 250 g , were divided into 6 groups of six rats each as (1) NC - normal control with normal diet (2) EC - alcohol control fed on alcohol for thirty days ; (3) EX -1 MEO G (methanol extract of Ocimum grat issimum ) only to check the toxicity of the extract , (4) EX - 2 MEOC (methanol extract of Ocimum canum ) only to check whether the extract had any toxic effect of its own and (5) EX - 3 MEOG after treating with ethanol for thirty days and confirming the hepatotoxicity, and (6) EX - 4 MEOC after the ethanol treatment . The rats were sacrificed after 30 days, and the blood collected for biochemical estimations . The results indicated that there were significant difference between the experimental rats (EX -groups) when compared with alcohol control (EC - group) in all the parameters checked and they were not significantly different from the normal control (NC -group) . The curative effect was established in groups 5 and 6, which showed a significant difference in antioxidant levels of all the parameters checked and retrieved its antioxidant status almost to the normal control. To come to the absolute normal condition of antioxidant levels it might have been needed a prolonged treatment for a longer period. Again, the groups, treated with extracts only, did not show any negative effect, which clearly indicated that the extract had no toxic effects. The use of antioxidant is an important preventive and curative method to minimize the pathological and toxic effects of oxidative stress induced by ethanol toxicity. Thus from the result obtained we conclude that MEOG and MEOC could effectively restore the antioxidant system from the oxidative stress induced by ethanol toxicity. In addition, there were no significant differences between the curative effects of these two species of Ocimum in terms of their effect on oxidative stress induced by ethanol toxicity.

The role of oxidative stress in cisplatin (CP) toxicity and its prevention by pretreatment with selenium (Se) was investigated. Male Wistar albino rats were injected with a single dose of cisplatin (7.5 mg CP/kg b.m., i.p.) and selenium (6 mg Se/kg b.m, as Na2SeO3, i.p.) alone or in combination. The results suggest that CP intoxication induces oxidative stress and alters the glutathione redox status: reduced glutathione (GSH), oxidized glutathione (GSSG) and the GSH/GSSG ratio (GSH RI), resulting in increased lipid peroxidation (LPO) in rat liver. The pretreatment with selenium prior to CP treatment showed a protective effect against the toxic influence of CP on peroxidation of the membrane lipids and an altering of the glutathione redox status in the liver of rats. From our results we conclude that selenium functions as a potent antioxidant and suggest that it can control CP-induced hepatotoxicity in rats.

Nonsteroidal anti-inflammatory drugs are associated with an increase in cardiovascular events despite its uses in the therapeutic agent for the management of long- and short-term pain. Over the last years, evidence has accumulated showing that oxidative stress plays an important role in the pathogenesis of cardiovascular diseases. Oxidative stress is no longer considered as a simple imbalance between the production and scavenging of reactive oxygen species (ROS), but as a dysfunction of enzymes involved in ROS production. This study investigated the effect of diclofenac on the activity of oxidative stress enzymes as well as formation of lipid peroxidation. Male rats weighing about 100-120 g were divided into four groups: group one (control, feed+water) group two, group three and group four treated with different mg/kg/day of drugs (50 mg/kg/day, 100 mg/kg/day and 150 mg/kg/day) feed and water respectively for 7 days. Analysis on the effect of diclofenac on the activities of stress enzymes such as nicotine adenosine dinucleotide phosphate hydrogenase oxidase (NADPHoxidase), xanthine oxidase(XOD), catalase(CAT), superoxide dismutase(SOD) and Glutathione Peroxidase as well as evaluation of lipid peroxidation by measuring malondialdehyde (MDA) in the heart homogenate were carried out and the result showed a significant increase in each parameter given rise to the production of reactive oxygen species (ROS) if not moderated by the antioxidant defense can lead to cardiac impairment as a result of oxidative stress damage or injury. The result obtained implies that diclofenac (NSAIDs) affects the redox status of vascular tissues (heart tissues).
