摘要: 为了研究紫杉醇治疗小鼠S180肉瘤的31P MRS参数的变化及这些参数的变化是否早于常规观察的瘤体积的变化.方法:利用表面线圈31P NMR方法,研究小鼠皮下接种的S180肉瘤.结果:用药48h后给药组的PCr/Pi、β-NTP/Pi、PME/β-NTP比值与对照组有显著性差别(P<0.05),而肿瘤体积在给药组和对照组之间无显著性差别,31P MRS参数的变化早于瘤体积变化.结论:小鼠S180肉瘤31P MRS不仅可以给出定量的结果,而且可以较早地显示出治疗的效果.

Abstract: Objective:To study whether the changes of 31P MRS parameters of mouse S180 sarcoma treated by Taxol is earlier than the changes of tumor volume. Methods:Mouse S180 sarcoma (i.p.) was studied by using surface-coil 31P NMR. Results:After 48h following treatment, PCr/Pi and β-NTP/Pi ratios of treated groups are higher than those of control group (P <0.05), PME/β-NTP ratio of treated groups is lower than that of control group (P <0.05). The tumor volume between treated groups and control group showed no significant difference. Conclusion:31P MRS of mouse S180 sarcoma can offer not only quantitative information, but show also earlier response to therapy.
