Effect of tritoqualine (TRQ) on liver regeneration after partial hepatectomy in normal rats and chronically injured rats treated with carbon tetrachloride (CCl4) for 12 weeks were investigated by the measurement of serum and liver biochemical parameters concerning the hepatic function. The results are as follows: 1) In normal rats, the liver regeneration rate after partial hepatectomy was increased dose-dependently with the administration of TRQ for 7 days after the operation. TRQ improved BSP retention rate which was decreased after partial hepatectomy. In addition, protein synthetic activity in the liver microsomes prepared from TRQ-administered rats was higher than that prepared from control rats, and the contents of serum total protein, serum albumin and liver protein were also higher in TRQ-administered rats. 2) In the rats treated with CCl4 for 12 weeks, the liver regeneration rate after partial hepatectomy was increased dose-dependently with the administration of TRQ for 6 days. TRQ also improved the contents of serum total protein, serum albumin and liver protein. Though the amount of collagen in the liver chronically injured by CCl4 increased more than twice compared with that in the normal liver, the amount of collagen in the regenerating liver of CCl4-treated rats whose liver regeneration was accelerated by TRQ was not different from that in the normal liver. These results suggest that TRQ has the effect of improving the various hepatic functions through the activation of the protein synthesis in hepatocytes. |
