Hepatoprotective Effects of Heracleum candicans Against Carbon Tetrachloride-Induced Acute Liver Injury in Rats.

PURPOSE: To determine the hepatoprotective mechanisms of Heracleum candicans in rats with acute liver injury induced by carbon tetrachloride (CCl4). METHODS: Rats were intragastrically administered H candicans twice a day for 14 consecutive days and were intraperitoneally challenged with CCl4. Alanine aminotransferase and aspartate aminotransferase were measured to indicate liver injury. Malondialdehyde antioxidant enzyme activity and tumor necrosis factor-alpha and interleukin 6 secretion were measured as liver injury indicators. Histopathological tests were conducted to determine whether H candicans ameliorated liver injury. RESULTS: CCl4-induced liver injury led to significant increases in liver injury biochemical indicators transaminase and malondialdehyde activities. H candicans pretreatments inhibited these increases. Pathological sections in pretreated samples exhibited reduced vacuole formation, neutrophil infiltration, and necrosis. CONCLUSION: H candicans increases the antioxidant capacity of the liver and maintains hepatocyte function in the face of CCl4-induced injury.
