The purpose of this study was to investigate the pharmacological effects of low-esterified pectin on carbon tetrachloride hepatotoxicity in rats. The study included two experiments. In the first experiment the animals were given daily through gavage for 7 days and then 10, 50, or 250 mg/kg b.w. of pectin for 21 days. At the end of experiment rats were killed within 24 hours. The increased bilirubin level, enhanced alanine aminotransferase and aspartate aminotransferase activity in plasma induced by were partly normalized by pectin administration in a dose-dependent manner. The pectin treatment also resulted in significant recovery of decrease of the liver glycogen content. In addition, pectin significantly improved alterations of pro-oxidant and antioxidant biochemical parameters in liver and plasma compared to those of rats administered . In the second experiment the animals were given daily 10, 50 or 250 mg/ kg b.w. of pectin for 21 days before a 7-day administration of . Rats were killed 24 hours after the end of experiment. Pretreatment with pectin before administration resulted in significantly inhibited increase of the blood enzymatic activities of alanine and aspartate aminotransferases and bilirubin level in a dose-dependent manner. Also, preliminary administration of pectin prevented elevation of malondialdehyde and conjugated diene levels in liver and plasma as well as a reduction of glutathione content in liver of rats given . These results suggest that low-esterified pectin exert healing and preventive effects on hepatotoxicity in rats.
