RESUMO
Objective To explore whether the Chinese medicine Guben Yiliu III can improve the effect of gemcit -abine on human pancreatic cancer xenograft in nude mice . Methods Nude mice with transplanted human pancreatic cancer were divided randomly into 4 groups: control group, gemcitabine treatment group , combined ( Guben Yiliu III +gemcitabine) group, and Guben Yiliu III group, 10 mice in each group.The gemcitabine group and combined group were treated with gemcitabine from the 8th day after transplantation in a dose of 100 mg/kg by i.p.injection, twice a week. Guben Yiliu III and combined groups were given the aqueous solution of Guben Yiliu III granules p .o.since the 8th day af-ter transplantation .Result The inhibition rate of transplanted tumor in the three treatment groups were 48.9% in the gemcitabine group , 68.9%in the combined group , and 28.0%in the Guben Yiliu III group .The combined group showed a significantly higher inhibition rate than the gemcitabine group (P<0.05).The gemcitabine group, combined group and Guben Yiliu III group showed a significantly slower growth rate than the control group .However, the combined treatment group showed a pronounced side effect and body weight loss than the other 3 groups .Conclusions The Chinese medicine Guben Yiliu III can improve the inhibitory effect of gemcitabine on nude mice with human pancreatic cancer xenograft in the auxilla of nude mice .
