Purpose: The effects of oral administration of ethyl acetate, ethanol and aqueous extracts of Adenema hyssopifolium G.Don (Gentianaceae) on carbon tetrachloride-induced liver disorders were investigated. Methods: Rats were individually treated daily with 300 and 600 mg/kg dose of either ethyl acetate, ethanol or aqueous extracts of A. hyssopifolium, respectively, following induction of liver da...

Conclusions: Our findings suggest that ethanol upregulates NQO1 expression by activating the AhR-Nrf2 pathway. Long-term exposure sustains low level of AhR protein and diminishes inducibility its target genes Nrf2 BaP. These will contribute to understanding synergistic toxicity polycyclic aromatic hydrocarbon compounds, such as

The effect of petroleum ether (60-80 C), ethanol and aqueous extracts of Datura stramonium Linn. leaves on the estrous cycle were studied and identify the estrogenic activity of active ethanol extract in female albino rats. After the oral acute toxicity study, plant extracts were administered at two dose levels: 200 and 400 mg/kg, respectively. Ethanol extract at a dose of 200 mg/kg has increas...

BACKGROUND Curcuma purpurascens BI. is a medicinal plant from the Zingiberaceae family, which is widely used as a spice and as folk medicine. The aim of the present study is to investigate the gastroprotective activity of C. purpurascens rhizome hexane extract (CPRHE) against ethanol- induced gastric ulcers in rats. METHODS Acute toxicity test was carried out on 36 rats (18 males and 18 femal...

It has been reported that naturally occurring quercetin exerts hepatoprotective effects through heme oxygenase-1 (HO-1) induction. However, the precise mechanism of how ethanol-associated liver damage is counteracted by quercetin-enhanced HO-1 metabolism still remains unclear. To further decipher the protective role of quercetin on ethanol-induced liver damage, we treated human hepatocytes with...

background organic solvents are widely used in cell biology experiments. despite increasing the solubility, they have some moderate toxic effects. therefore, selecting the appropriate solvent along with the use of suitable concentration insures the accuracy and reliability of experimental results. objectives the current study aimed to examine the cytotoxic effects of some organic solvents on va...

Ethanol-blended gasoline has been used in Brazil for 20 years and, probably, is going to be more widely used in North America due to the MtBE environmental effects on groundwater. The potential impacts caused by the presence of ethanol in UST spills are related to the co-solvency effect and the preferential degradation of ethanol over the BTEX compounds. These interactions may increase the leng...

Objective: Chronic ethanol consumption has significant negative effects on liver tissue. Mechanisms of ethanol toxicity include oxidative stress and inflammation. The antioxidant and anti-inflammatory properties of the lemon verbena have been proven in studies. The aim of this study was to evaluate the protective effect of hydro alcoholic extract of Aloysia citriodora (AC) on ethanol-induced he...

Bernard B. Brodie's laboratory was the first to examine the mechanisms of drug-induced toxicity at the molecular level. They found that acetaminophen hepatotoxicity was due to the metabolic activation of the drug to a highly reactive toxic metabolite that depleted cellular glutathione and covalently bound to protein. Subsequent studies revealed that activation of acetaminophen to an active meta...

BACKGROUND Dilute acid pretreatment is a promising pretreatment technology for the biochemical production of ethanol from lignocellulosic biomass. During dilute acid pretreatment, xylan depolymerizes to form soluble xylose monomers and oligomers. Because the xylan found in nature is highly acetylated, the formation of xylose monomers requires two steps: 1) cleavage of the xylosidic bonds, and 2...
