ABSTRACT
OBJECTIVE:To study the protecting effect of Phellinus igniarius on liver injury.METHODS:Liver injury was induced by carbon tetrachloride in rats.Parameters of serum samples and tissue samples were analyzed to show the effect of Phellinus igniarius on liver injury.RESULTS:Degeneration of hepatocytes was obviously prevented in rats treated with Phellinus igniarius;the liver construction was well maintained.Phellinus igniarius could significantly decrease the serum levels of aminotransferase,active oxygen and IL-4,while increase the serum level of IFN-?and SOD activity in liver tis?sue.CONCLUSION:Phellinus igniarius can protect hepatocytes from injury through anti-lipid peroxidation and regulating inflammatory factors.
ABSTRACT
AIM To research effects of sodium ferulate(SF) on transforming growth factor ?_1 inhibited hepatocyte growth. METHODS Human cultured hepatocytes(L02 cells) served as control group ,TGF?_1(5 ?g?L -1 ) was used to inhibited L02 cells to construct the cell model. MTT methods were used to study the growth inhibitory effect of TGF?_1 on L02 cells. DNA synthesis was analyzed by measuring 3H-TdR incorporation. The effects of SF on the changes of cell cycle were analyzed by flow cytometry. Generation of intracellular ROS was determined by the emission of fluorescence in L02 cells proloaded with DCFH-DA fluoresin and then treated them with TGF?_1 or SF. After 4h,control, TGF?_1 and TGF?_1+SF-treated cells were analyzed by flow cytometry. RESULTS ①Incubated in the presence of TGF?_1 for 24 h, 67.93% of L02 cells survived (P
