| 1 | Influence of As_2O_3 combined with ginsenosides Rg3 on inhibition of lung cancer NCI-H1299 cells and on subsistence of nude mice bearing hepatoma显示文摘Objective:To study the effect of arsenic trioxide(As_2O_3)combined with ginsenosides Rg3 on inhibiting the NCI-H1299 lung cancer cells and subsistence in nude mice bearing hepatoma.Methods:MTT method was used to measure the inhibition effect of(As_2O_3)combined Rg3 on NC1-H1299 cells,and the proliferation inhibiting effect was observed via establishing the transplanted tumor model in vitro.A total of 40 tumor-bearing nude mice were randomly divided into normal saline group,(As_2O_3),Rg3 and As_2O_3+Rg3 group.Transplantation tumor model of lung cancer in nude mice was constructed,followed by injection of certain concentrations of normal saline,As_2O_3,ginseng saponin Rg3 and As_2O_3+Rg3 every day.The survival duration and the tumors size of the mice were recorded and the Kaplan-Meier curve was made;microscopic observation of apoptosis of tumor cells in vivo was done using TUNEL staining.Results:After 72 h of injection.inhibition rate of tumor cell in normal saline group,As_2O_3 group.Rg3 group and As_2O_3+Rg3 group was(5.66±0.31)%,(65.58±4.75)%,(44.69±3.32)%and(82.67±5.43)%,respectively.Inhibition rate of tumor cell in As_2O_3 group.Rg3 groap and As_2O_3+Rg3 group was significantly higher than that of normal saline group(P<0.01);inhibition rate of tumor cells of As_2O_3+Rg3 group was significantly higher than that of the two groups given As_2O_3 or Rg3 alone(P<0.01).The tumor volume of As_2O_3 group,Rg3 group and As_2O_3+Rg3 group shrank to(65.38±3.25)%,(77.68±3.43)%and(42.65±3.55)%of the original,tumor volume of saline group was 1.21 times of the original size(P<0.01);Median survival of saline group,Rg3 group,As_2O_3 group were significantly shorter than that of As_2O_3+Rg3 group(P<0.01);co-ordinated intervention ability of As_2O_3+Rg3 on NCI-H1299 cell was significantly higher than that of As_2O_3 or Rg3,separately.Conclusions:As_2O_3 combined with Rg3 can significantly inhibit prolifaration of NCI-H1299 cells in lung cancer,prolong survival fo tumor-bearing nude mice,and promote tumor cell apoptosis,and have significant effect on lung cancer treatment. | Jian-Bo Che Zhong-Hua Liu Hong-Bing Ma Yong Li Hui Zhao Xiao-Hui Li Wei-Chao Liu Gong-Ning Shi | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，10： | 3 |
