چکیده

the effects of different concentrations of the hydroalcoholic extract of dried powdered leaves of cichorium intybus l., on ccl4-induced hepatotoxicity in vivo in rats and ccl4-induced cytotoxicity in isolated rat hepatocytes were investigated. rats received different concentrations of the extract by i.p. injection for 3 consecutive days before the injection of (3ml/kg) ccl4 (i.p.). twenty four h after ccl4 injection the animals were sacrificed and the livers were dissected for biochemical and histopathological studies. the results showed that the cichorium intybus extract could protect the liver from ccl4-induced damages with doses of 50 and 100 mg/kg, but concentrations higher than 200 mg/kg were less effective. for in vitro studies, the extract were added to the suspension of freshly isolated rat hepatocytes incubated in krebs-henseleit buffer under a gas flow of 95% o2 and 5% co2, 20 minutes before the addition of 10 mm of ccl4. the extract with concentrations of 60 to 600 µg /ml protected the cells against ccl4-induced cytotoxicity, but concentrations of ? 1.5 mg/ml and higher increased the ccl4-induced cytotoxicity. the cichorium intybus extract itself was toxic towards isolated hepatocytes in concentrations above 3.6 mg/ml. the results of the present study therefore supported the traditional believes on hepatoprotective effect of the cichorium intybus extract, however, high concentrations were hepatotoxic.

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...
