Hsu YW, Tsai CF, Chang WH, Ho YC, Chen WK, Lu FJ: Protective effects of Dunaliella salina--a carotenoids-rich alga, against carbon tetrachloride-induced hepatotoxicity in mice. Food Chem Toxicol. 2008 Oct;46(10):3311-7. Epub 2008 Aug 12.
The protective effects of Dunaliella salina (D. salina) on liver damage were evaluated by carbon tetrachloride (CCl (4))-induced hepatotoxicity in mice. Male ICR mice were orally treated with D. salina or silymairn daily with administration of CCl (4) twice a week for 8 weeks. CCl (4) induced liver damage and significantly (p <0.05) increased the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) in serum and decreased the activities of superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px), and GSH content in liver whereas increased hepatic malondialdehyde (MDA) content as compared with control group. Treatment with D. salina or silymarin could significantly (p <0.05) decrease the ALT, AST, and ALP levels in serum and increase the activities of SOD, catalase, GSH-Px, glutathione reductase, and GSH content and decrease the MDA content in liver when compared with CCl (4)-treated group. Liver histopathology also showed that D. salina reduced the incidence of liver lesions induced by CCl (4). The results suggest that D. salina exhibits potent hepatoprotective effects on CCl (4)-induced liver damages in mice, and that the hepatoprotective effects of D. salina may be due to both the increase of antioxidant enzymes activities and inhibition of lipid peroxidation. |
