Given study evaluates the cardioprotective effect of crocetin in myocardial infracted (MI) rats. MI was produced by administering isoproterenol (90mg/kg/day, i.p.) in rats for two consecutive days. all the animals were divided in to four groups such as control group receives only saline; MI group which receives only isoproterenol and crocetin treated group which receives crocetin (50, 100 and 200mg/kg/day, p.o.) for the duration of 15 days. At the end of dosing left ventricular functions was assessed to estimate its effect on cardiac functions...

Terminalia bellirica (Gaertn.) Roxb. is a medicinal plant used for the treatment of various ailments in the traditional system of medicine like Ayurveda where it has been prescribed as a rejuvenator and general health tonic. The fruit of the plant is one of the components of the age old ayurvedic formulation-'Triphala'. The present study evaluates curative effect of aqueous acetone extract of Terminalia bellirica fruits (AATB) against CCl4 induced oxidative stress and liver damage in an animal model. Two doses of the fruit extract (200mg/kg body weight and 400mg/kg body weight) were investigated for the beneficial effects...

The aim of this study was to investigate the impacts and modes of action of a chemical and nutrient deprivation on the cellular senescence process of Chlamydomonas reinhardtii. Several molecular and cellular parameters related to senescence phenomena were monitored in C. reinhardtii cells exposed for 24h to a sublethal concentration (0.25μM) of the herbicide atrazine and in unexposed 96h cells in an early stationary phase of growth. All endpoints showed the same pattern of response between treatments, except for the intracellular level of calcium, where a significant increase was observed in 24h-exposed cultures compared to 24h-log controls...

The present study was designed to investigate the protective effects of Ilex Kuding tea polysaccharides (IKTP) on high fructose (HF)-induced liver injury and vascular endothelial dysfunction in mice. IKTP were identified as acidic heteropolysaccharides by FT-IR and HPLC. Healthy male Kunming mice fed 20% fructose in drinking water for 8 consecutive weeks significantly displayed dyslipidemia, hepatic steatosis, oxidative stress and vascular endothelial dysfunction. However, continuous administration of IKTP at 200, 400 and 800 mg per kg bw in HF-fed mice could prevent the damage caused by HF-diets, especially at dosages of 400 and 800 mg per kg bw (p < 0...

Mulberry fruit polysaccharide (MFP), one of the major active ingredients isolated from the mulberry fruit, possesses numerous bioactivities. In vitro hypoglycemic experiments showed that MFP had significant insulin-sensitizing activity through increasing insulin secretion and promoting pancreatic β cell proliferation. In vivo, the oral administration of MFP could significantly decrease blood glucose levels and increase body weight loss in streptozotocin (STZ)-induced diabetic mice. MFP also significantly decreased the level of malondialdehyde (MDA) and increased the activities of antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) in the liver in STZ-induced diabetic mice...

The water-soluble polysaccharides extracted from Sipunculus nudus (SNP) was investigated on the lifespan and immune damage repair of Drosophila melanogaster exposed to Cd (VI). SNP increased superoxyde dismutase (SOD), nitrogen monoxide (NO), glutathione peroxidase (GSH-Px) and total anti-oxidation competence (T-AOC), with decreased malondialdehyde (MDA) on D. melanogaster demonstrated that SNP could attenuate oxidative damage of D. melanogaster Exposed to Cd (VI). Real-time PCR and western blot analysis showed that SNP enhanced the gene expression of Diptericin, Drosomycin, Defensin, PGRP-LC and the protein level of Toll, p-JNK and Relish, that suggested the promoting effect of SNP on the immune damage repair of D...

OBJECTIVES: Impact of ROS in development of hyperalgesia has recently motivated scientists to focus on ROS as novel target of anti-hyperalgesic interventions. However, role of ROS in molecular signaling of hyperalgesia is still poorly understood. The present study is aimed to analyze the effect of dietary antioxidant resveratrol on antioxidant defense system, ROS level and TNFR1-ERK signaling pathway during early and late phase of inflammatory hyperalgesia. METHODS AND MATERIALS: Hyperalgesia was assessed by paw withdrawal latency test in complete Freund's adjuvant-induced hyperalgesic rats...

The ameliorative effect of H2 on aluminum (Al)-induced stress remains poorly understood. We treated maize seedlings with Al and hydrogen-rich water (HRW) to determine the roles of H2 in the alleviation of Al toxicity. Our results demonstrated that Al stress triggered damage to the photosynthetic apparatus, plant growth inhibition, and reactive oxygen species (ROS) production, and boosted lipid peroxidation. However, the addition of HRW at 75% saturation markedly alleviated Al toxicity symptoms through the promotion of root elongation...

Oxidative stress plays an important role in neurodegenerative diseases and aging. The cellular defense mechanisms to deal with oxidative damage involve the activation of transcription factor related to NF-E2 (Nrf2), which enhances the transcription of antioxidant and phase II enzyme genes. S-allylcysteine (SAC) is an antioxidant with neuroprotective properties, and the main organosulfur compound in aged garlic extract. The ability of SAC to activate the Nrf2 factor has been previously reported in hepatic cells; however this effect has not been studied in normal brain...

We have investigated gross pathology, physiological (steroid precursors) and toxicological responses (oxidative stress and phase II biotransformation) in relation to tissue contaminant burden in Tilapia species along the entire length (320 km) of Ogun River, Nigeria. The Ogun River is the longest and largest river in Southwestern Nigeria located along heavily industrialized cities and receives complex mixtures of effluents. A total of 1074 tilapias were collected from three sampling points (Abeokuta, Isheri and Ikorodu) and from an upstream control point (Igboho) and evaluated for gross pathological changes, hepatic transcript levels for oxidative stress and phase II biotransformation responses...

3, 4-Dihydroxybenzalacetone (DBL) is a constituent of Phellinus linteus. This study demonstrated the protective effect of DBL on lipopolysaccharide (LPS)-induced acute lung injuries in mice. Pretreatment with DBL significantly improved LPS-induced histological alterations in lung tissues. In addition, DBL markedly reduced the total cell number, the leukocytes, the protein concentrations, and decreased the release of nitrite, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and the activities of matrix metalloproteinase (MMP)-2 and -9 in the bronchoalveolar lavage fluid...
