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...

1. The general features of the reaction by which carbon tetrachloride stimulates lipid peroxidation have been elucidated in rat liver microsomal suspensions and in mixtures of microsomes plus cell sap. The production of lipid peroxides has been correlated with malonaldehyde production in the systems used. 2. The stimulation of malonaldehyde production by carbon tetrachloride requires a source o...

Liver function tests, thyroxin and triiodothyronine levels, and hepatic 5’deiodinase and glutathione peroxidase enzyme activities were measured. Triiodothyronine levels in the carbon tetrachloride group and carbon tetrachloride + selenium group were significantly lower than in the control group (P<0.01, P<0.05, respectively). In the carbon tetrachloride + selenium group, the level of triiodothy...

the present study appraised the hepatoprotective activity of aqueous extract of camellia sinensis leaves and its possible mechanism of action against carbon-tetrachloride-induced liver damage. liver damage was induced by   intraperitoneal administration of equal mixture of carbon tetrachloride   and olive oil (50 % v/v, 0.5 ml/kg ) in male wistar rats (150-220g) once daily for 7 days and the ex...

Metabolism of carbon tetrachloride is essential for its toxic effect on intracellular components of the hepatocytes (Butler, 1961 ; Recknagel, 1967). Carbon tetrachloride decreases the biliary excretion of foreign organic compounds of high molecular weight (Barakat & Abou-El-Markarem, 1973). Whether metabolism of carbon tetrachloride is also essential for this effect, will be discussed here. Va...

the ethanolic extract of ficus carica leaves was screened for hepatoprotective and antioxidant activity in hepatotoxic albino rats induced via carbon tetrachloride. the degree of protection was measured by estimating biochemical parameters such as serum glutamate oxaloacetate transaminase (sgot), serum glutamate pyruvate transaminase (sgpt), total protein (tp), total albumin (ta), alkaline phos...

protective action of ficus carica leaf ethanolic extract (obtained by maceration) was evaluated in an animal model of hepatotoxicity induced by carbon tetrachloride (ccl4). male albino mice were divided into six groups. group i was normal control group; group ii received olive oil (ccl4 solvent), groups iii-vi received ccl4. after inducing hepatic damage, group iii served as control for ccl4; a...

cirrhosis is the consequence of chronic liver disease. deleterious effects of oxidative stress on hepatocytes may be reflected in the erythrocyte membrane. naltrexone (ntx) has been shown to attenuate hepatocellular injury in fibrotic animal models. the aim of this study was to investigate the progressive effect of ccl 4 on the liver and whether the improvement of liver cirrhosis can be monitor...

Rat liver microsomal membranes contain a reduced-glutathione-dependent protein(s) that inhibits lipid peroxidation in the ascorbate/iron microsomal lipid peroxidation system. It appears to exert its protective effect by scavenging free radicals. The present work was carried out to assess the effect of this reduced-glutathione-dependent mechanism on carbon tetrachloride-induced microsomal injury...
