摘要
经活化的肺泡巨噬细胞(PAM)能抑制Hela细胞的增殖,其细胞毒性指数为57.90±2.48(P<0.01)。PAM的这种细胞毒功能可被大气飘尘(AP)降低,在AP浓度为10~100μg/ml范围内这种降低作用显示剂量-反应关系,在10、50、100μg/mlAP作用下,PAM对Hela细胞的细胞毒指数分别为51.91±3.67(P>0.05)、40.83±2.14(P<0.01)、32.33±4.55(P<0.01)。在500μg/mlAP作用下,由于大量的PAM脱落和死亡,其细胞毒指数仅为14.98±3.29(P<0.01)。提示大气飘尘具有降低肺巨噬细胞抗肿瘤免疫的作用。
The activated pulmonary alveolar macrophage (PAM) can inhibit proliferation of Hela cell.The cytotoxicity index is 57.90±2.48(P<0.01).The PAM's function can be weakened by the airborne particulate (AP).The result exhibits relationship of dose-response in the concentrations 10 ̄100μg/ml.The cytotoxicity indices are 51.91 ±3.67 (P>0.05 ), 40.83±2.14 (P<0.01 ), 32.33±4.55 (P<0.01) at the concentration of 10, 50, 100μg/ml of AP respectively.At the concentration of 500μg/ml, because of a lot of PAM falling off and dying, the cytotoxicity index is only 14.98±3.29 ( P<0.01 ).The results indicate that AP can reduce the tumoricidal action of PAM.
