  • In this study, we investigated the effects of detoxified puffer liver (PL) oil on fatigue, hepatotoxicity and hyperlipidemia. There are no toxicities in both raw and purified PL oil. The test of swimming time was extended in detoxified PL oil pretreated group compared to the non-treated group. When rats treated with PL oil, the hepatic injuries induced by carbon tetrachloride or DL-galactosamine were reduced. The increased serum triglyceride and total cholesterol by poloxamer-407 were lowered by treating with PL oil remarkably. Also the bleeding time of hyperlipidemic animals was extended and plasma clotting time was delayed by PL oil.

  • This study was carried out to investigate physiological activities of chicory root (Cichorium intybus L. var. sativus). The anti-hepatotoxic activity of roasted chicory was studied using primary cultured rat hepatocytes where cytotoxicity was induced by galactosamine. The water extract of roasted chicory did not induced of cytotoxicity in primary cultured rat hepatocytes. Treatment with 5 mM galactosamin for 5.0 hr showed maximum increase in activity of lactic dehydrogenase (LDH) released in the medium. The water extract of roasted chicory inhibited significantly and dose-dependently the release of LDH activity increased by galactosamine-induced cytotoxity. The antidiabetic activity of water extract of roasted chicory was examined in streptozotocin induced diabetic rats. The increased blood glucose level in the streptozotocin induced diabetic rats was significantly decreased by the administration of chicory extract (800 mg/kg). Chicory water extract (800 mg/kg) prevented weight losses in streptozotocin induced diabetic rats. The antimutagenic activities of chicory water extract were tested using Salmonella thyphimurium YG 1024 as tester strains and 2-aminofluorence as a potent carcinogen in the presence of S-9 mix. No mutagenic activities of the water extracts of roasted chicory were observed on all the tested strains at dose $10{\sim}5,000$ ${\mu}/g$ per plate. Water extract of roasted chicory did not inhibit the mutagencities of Salmonella thyphimurium YG 1024 induced by 2-aminofluorene.
