【摘要】 目的:探讨单核细胞趋化蛋白-1(MCP-1)含量及其活性-单核细胞趋化活性(MCA)变化与肺癌发病的关系。方法:以ELISA法测定肺癌组、良性肺病组及健康对照组支气管肺泡灌洗液(BALF)中MCP-1的含量,并同时测定各组BALF的MCA。结果:肺癌组BALF的MCP-1含量及MCA明显高于良性肺病组及健康对照组,均P<0·01。但肺癌组BALF中MCP-1含量与MCA的相关系数却明显低于良性肺病组和健康对照组;即在肺癌组MCA活性并没有随MCP-1含量增加而成正比地增加。结论:肺癌患者可能存在单核细胞趋化活性不足。更多还原

【Abstract】 AIM: To investigate the relationship among MCP-1 and monocyte chemoattract protein activity (MCA) and pathogenesis of lung cancer. METHODS: 173 patients were involved in the study and divided into three groups: group A: lung cancer group (60 patients); group B: benign lung disease group (55 patients) and group C: healthy control group (58 patients). MCP-1 level and MCA in bronchoalveolar lavage fluid (BALF) were measured. RESULTS: The concentration of MCP-1 and MCA in BALF in group A were much higher than those in group B and group C (P<0.01), but the increase in MCA were not in direct proportion to the increase in MCP-1 in the patients with lung cancer. CONCLUSION: Monocyte chemoattract activity of the patients with lung cancer may be insufficient.更多还原
