Abstract:
Objective To investigate the effects of Compound E-Jiao Slurry (CEJS) and Cyclophosphamide (CTX) on the inhibition of Lewis pulmonary carcinoma xenografts. Methods Tumor xenografts models were prepared and randomly divided into six groups by weight, including the control group,CTX, CEJS with the dosages of high, middle and low, with a total of ten mice in each group. The control mice were given normal saline 0.4ml by intragastric administration once daily, with a total of twelve times; The mice of CTX group were given CTX 0.2 ml by intraperitoneal injection every other day, with a total of six times; The mice of CEJS group were given CEJS 0.2 ml and saline 0.2 ml by intragastric administration; The mice of combination therapy group 1 were given CEJS 0.4 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day; The mice of combination therapy group 2 were given CEJS 0.2 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day; The mice of combination therapy group 3 were given CEJS 0.1 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day. The weight of tumor xenografts were measured in the experiment,the inhibition rate of tumor xenografts were calculated according to the data after the dissection. Results The combination groups and CTX alone have an inhibition rate of over 50%, and the CEJS group 25.88%. In every experimental group, the weight of tumor showed statistical significance compared with the control (P<0.05). The value was(4.457±0.796)g, (2.105±0.651) g, (3.304±0.922) g, (1.668±0.267)g, (1.752±0.546)g and (2.075±1.061) g respectively according to the group sequence. There was no statistical significance of tumor weight in the groups of different dosages of CEJS plus CTX compared with the CTX group (P>0.05). Conclusion CEJS can't obviously enhance the sensitivity of tumor xenografts to CTX, but there is a trend for tumor inhibition.
