Disturbances in the antioxidant system could play a role in pathogenesis of chronic liver disease. The aim of our study was to evaluate the levels/activities of antioxidants in blood of patients with chronic liver disease. We estimated selenium and glutathione concentrations and glutathione peroxidase activities in blood of 59 patients with chronic hepatitis B or C virus infection (group 1) and...

Eggplant leaves (Solanum macrocarpon) are rich in nutrients which unfortunately lost during cooking. To reduce micronutrients losses and enhance antioxidant potentialities, they were cooked water for 30 minutes with onion, ginger Guinea pepper. The analyzes focused on the determination of vitamin C, β-carotene, phenolic compounds, free radical-scavenging lipid peroxidation inhibitory act...

Experiments were conducted to understand the therapeutic properties such as anti-inflammatory, anti-oxidative, haematological and serum biochemical markers of earthworm paste (EP) derived from an indigenous species Lampito mauritii (Kinberg), in comparison with the standard anti-inflammatory drug- aspirin, on Wistar albino rat (Rattus norvegicus). Administration of earthworm paste of Lampito ma...

Objectives: To study the effect of oral administration of Piper betle leaf powder suspension on lipid peroxidation and antioxidants in streptozotocin (STZ) diabetic rats. Methods: Male Wistar strain rats were orally administered the leaf suspension of P. betle, (75 and 150 mg/kg body weight) for 30 days. Plasma and erythrocytes were separated out and the liver and kidney were homogenized in ice...

The aim of this study was to evaluate the effect of a long-term peroral selenium supplementation in the form of sodium selenite and selenium lactate-protein complex by comparing selenium concentrations and glutathione peroxidase activity in blood of goats and their kids as well as comparing selenium concentrations in goat colostrums. For the study, a total of 27 clinically healthy pregnant whit...

Effects of S-allylcysteine (SAC), an organosulfur compound of garlic, on circulatory lipid peroxidation and antioxidant levels were evaluated in N-nitrosodiethylamine (NEDA)-induced hepatocarcinogenesis in Wistar rats. Significantly elevated thiobarbituric acid reactive substances in the circulation of rats bearing carcinoma indicated the higher levels of lipid peroxidation which was accompanie...

Hibiscus sabdariffa (HS) is an edible medicinal plant, indigenous to India, China and Thailand and is used in Ayurveda and traditional medicine. Alcoholic extract of HS leaves (HSEt) was studied for its anti-hyperammonemic and antioxidant effects in brain tissues of ammonium chloride-induced hyperammonemic rats. Oral administration of HSEt (250 mg kg(-1) body weight) significantly normalizes th...

Melatonin has recently been suggested as an antioxidant that may protect neurons from oxidative stress. Acute ethanol administration produces both lipid peroxidation as an indicator of oxidative stress in the brain and impairs water-maze performance in spatial learning and memory tasks. The present study investigated the effect of melatonin against ethanol-induced oxidative stress and spatial m...

The effect of enalapril and captopril on total glutathione content (GSSG + GSH) and selenium-dependent glutathione peroxidase (Se-GPx) and glutathione reductase (GSSG-Rd) activities was investigated in mouse tissues. CF-1 mice (4-mo-old females) received water containing enalapril (20 mg/l) or captopril (50 mg/l) for 11 wk. Enalapril increased GSSG + GSH content (P < 0.05) in erythrocytes (147%...
