The curative effect of galactosylated chitosan/5-fluorouracil on liver cancer in the orthotopic transplant model of hepatocellular carcinoma. A: Five days after the tumor was established, galactosylated chitosan/5-fluorouracil (GC/5-FU), 5-FU, GC or phosphate buffered solution was given to the mice. Tumor weight was measured at day 15; B: Treatment was given as described previously and the survival was monitored. The median survival for control, GC, 5-FU and GC/5-FU groups were 12, 13, 17 and 30 d, respectively. bP < 0.01 vs control group; cP < 0.05 vs 5-FU group.
