摘　　要：This study investigated the effect of TNP-470 in combination with carmustine (BCNU) on the growth of subcutaneously implanted human glioblastoma xenografts in nude mice.Human glioblastoma U-251 cells (1×10 7) were injected into 24 nude mice subcutaneously.The tumor-bearing mice were randomly divided into 4 groups on the seventh day following tumor implantation:TNP-470 group,in which TNP-470 was given 30 mg/kg subcutaneously every other day 7 times;BCNU group,in which 20 mg/kg BCNU were injected into peritoneal cavity per 4 days 3 times;TNP-470 plus BCNU group,in which TNP-470 and BCNU were coadministered in the same manner as in the TNP-470 group and the BCNU group;control group,in which the mice were given 0.2 mL of the mixture including 3% ethanol,5% acacia and 0.9% saline subcutaneously every other day 7 times.The tumor size and weights were measured.The tumor microvessel density (MVD) was determined by immunostaining by using goat-anti-mouse polyclonal antibody CD105.The results showed that on the 21th day following treatment,the volume of xenografts in the TNP-470 plus BCNU group was (108.93±17.63)mm 3,markedly lower than that in the TNP-470 group [(576.10±114.29)mm 3 ] and the BCNU group [(473.01±48.04)mm 3 ] (both P【0.01).And the xenograft volume in these 3 treatment groups was even much lower than that in the control group [(1512.61±470.25) mm 3 ] (all P【0.01).There was no significant difference in the volume of xenografts between the TNP-470 group and the BCNU group (P】0.05).The inhibition rate of the tumor growth in the TNP-470 plus BCNU group was (92.80±11.37)%,notably higher than that in the TNP-470 group [(61.91±6.29)%] and the BCNU group [(68.73±9.65)%] (both P【0.01) on the 21th day following treatment.There was no significant difference in the inhibition rate of tumor growth between the TNP-470 group and the BCNU group (P】0.05).The MVD of xenografts in the TNP-470 plus BCNU group was decreased significantly as compared with that in the TNP-470 group or the BCNU group (both P&This study investigated the effect of TNP-470 in combination with carmustine (BCNU) on the growth of subcutaneously implanted human glioblastoma xenografts in nude mice.Human glioblastoma U-251 cells (1×10 7) were injected into 24 nude mice subcutaneously.The tumor-bearing mice were randomly divided into 4 groups on the seventh day following tumor implantation:TNP-470 group,in which TNP-470 was given 30 mg/kg subcutaneously every other day 7 times;BCNU group,in which 20 mg/kg BCNU were injected into peritoneal cavity per 4 days 3 times;TNP-470 plus BCNU group,in which TNP-470 and BCNU were coadministered in the same manner as in the TNP-470 group and the BCNU group;control group,in which the mice were given 0.2 mL of the mixture including 3% ethanol,5% acacia and 0.9% saline subcutaneously every other day 7 times.The tumor size and weights were measured.The tumor microvessel density (MVD) was determined by immunostaining by using goat-anti-mouse polyclonal antibody CD105.The results showed that on the 21th day following treatment,the volume of xenografts in the TNP-470 plus BCNU group was (108.93±17.63)mm 3,markedly lower than that in the TNP-470 group [(576.10±114.29)mm 3 ] and the BCNU group [(473.01±48.04)mm 3 ] (both P<0.01).And the xenograft volume in these 3 treatment groups was even much lower than that in the control group [(1512.61±470.25) mm 3 ] (all P<0.01).There was no significant difference in the volume of xenografts between the TNP-470 group and the BCNU group (P>0.05).The inhibition rate of the tumor growth in the TNP-470 plus BCNU group was (92.80±11.37)%,notably higher than that in the TNP-470 group [(61.91±6.29)%] and the BCNU group [(68.73±9.65)%] (both P<0.01) on the 21th day following treatment.There was no significant difference in the inhibition rate of tumor growth between the TNP-470 group and the BCNU group (P>0.05).The MVD of xenografts in the TNP-470 plus BCNU group was decreased significantly as compared with that in the TNP-470 group or the BCNU group (both P&
