To evaluate the hepatoprotective and in vivo antioxidant effect of aqueous seed extract of Vigna unguiculata (AVU) against Carbon tetrachloride (CCl4) induced hepatic injury in rats. 30 male wistar rats were divided into five groups. Group 1 and 2 received plain groundnut oil (3ml/kg body weight p.o.) for 21 days and had free access to food and water. Group 3, 4 and 5 were pretreated with Silym...

BACKGROUND In vitro bioassays are important in the evaluation of plants with possible hepatoprotective effects. The aims of this study were to evaluate the pretreatment of HepG2 cells with hepatoprotective agents against the damage induced by carbon tetrachloride (CCl4) and paracetamol (APAP). METHODS Antioxidative activity was measured using an assay to measure 2,2-diphenyl-1-picrylhydrazyl ...

Background: Because reactive oxygen species (ros) contribute to the pathogenesis of various acute and chronic liver diseases, dietary antioxidants and drugs from herbal origins have been proved to be beneficial as therapeutic agents in reversing hepatotoxicity and oxidative stress. The objective of this study was to investigate the protective effect of an aqueous extract from smilax excelsa l. ...

In order to investigate the effects of peppermint (Mentha piperita L.) alcoholic extract on liver injury caused by the oxidant carbon tetrachloride (CCl4), an experiment was performed as a completely randomized design in a factorial arrangement (2 × 2) with 4 replications of 10 broilers each. Factors included two levels of peppermint leaf alcoholic extract (0 and 2 mL/Kg body weight) and CCl4 (...

Objectives: Carbon tetrachloride (CCl4) is one of the most dangerous hepatotoxic environmental pollutants thus this study aimed at investigating the potential preventive effect and mechanism of crocin against CCl4induced hepatotoxicity. Methods: Forty Male rats were allocated for two weeks treatment with; corn oil, CCl4 in corn oil, crocin (100 mg/ kg), or crocin plus CCl4. At time of euthanasi...

This study was designed to investigate in-vivo and in-vitro hepatoprotective activity of kaempferol isolated from Capparis spinosa L. in CCl4 intoxicated rat. Kaempferol is a bioflavonoid reported with antioxidant, antiinflammatory and antiapototic effects which can prevent CCl4 induced hepatic lipid peroxidative damage mediated by oxidative free radical. Kaempferol was isolated from C. spinosa...

Vitamin A (VA, retinol) has been shown to modulate cells of the immune system. When rats are pretreated with VA (75 mg/kg/day) for 7 days, there is greatly potentiated liver damage upon subsequent exposure to hepatotoxicants such as CCl4. This potentiated damage can be blocked by superoxide dismutase or catalase, suggesting that reactive oxygen species are playing a major role in the increased ...

The present study determines the efficacy of N-acetyl cysteine (NAC) on marker enzymes, lipid peroxidation and antioxidants in carbon tetrachloride induced hepatotoxicity in rats. Carbon tetrachloride (CCl4) (3 mL/kg/week) administered subcutaneously to albino Wistar rats for a period of three months significantly increased the activities of marker enzymes in plasma such as aspartate transamina...

The present study was undertaken to investigate the hepatoprotective effect of pantothenic acid on CCl4-induced liver damage. Male Wistar rats were orally treated with pantothenic acid (0.005, 0.01, 0.025, 0.05 and 0.1 g/kg) daily, with administration of CCl4 (1 mL/kg, 50 % CCl4 in olive oil) twice a week for 28 days. The effect of pantothenic acid on serum markers (alanine aminotransferase, as...
