摘要:

目的 通过观察腹膜腔注射肝素对ACC-M细胞在裸鼠肺、肝组织的分布特点,研究其对腺样囊性癌肺高转移细胞肺粘附的抑制作用。方法 实验裸鼠腹腔注射肝素后,经尾静脉注入氚标胸腺嘧啶核苷(3HTdR)标记 ACC-M细胞,分别检测注射后2 h、6 h、18 h肺、肝组织单位重量的每分钟同位素脉冲数(CPM)。结果 裸鼠单位重量肺组织3H-ACC-M在不同时间由高到低依次是空白对照组2 h、6 h、18 h,肝素组6 h、2 h、18 h。相同时段肝素组明显低于对照组,两组间有显著性差异(P<0·001)。单位重量肝组织3H-ACC-M在不同时间由高到低依次是空白对照组为2 h、6 h、18 h,肝素组为2 h、6 h、18 h,相同时段两组间无显著性差异(P>0·05)。结论 肝素腹腔注射后可减少肺组织内ACC-M细胞数量,但对相同时段肝组织内ACC-M细胞数量无显著影响,肝素可能在抑制腺样囊性癌肺转移中发挥作用。

Abstract:

Objective To investigate the effect of intraperitoneal heparin on the adhesion of highly lungmetastasic adenoid cys- tic carcinoma cell line (ACC-M) in lung.Methods 3HTdR labeled ACC-M cells were injected by intravenous infusion after in- traperitoneal injection with 200 units heparin. 4 mice of each group were killed at 2 h, 6 h and 18 h after infusion. The relative radioactivity (CPM) in lung and liverwas detected.Results 3H-activity pergram in lung of heparin groupwas lowerthan control at the same time. There was significant difference between the two groups (P<0.001). There was no difference between the two groups in liver (P>0·05).Conclusion The results of this study suggest that the highly lungmetastasis characteristic of ACC-M may be partially inhabited by the use of intraperitoneal heparin.
