Abstract

The method using lucigenin-dependent phagocytic chemiluminescence is described for the assessment of alveolar macrophage metabolic activity in response to stimulation by opsonised particles or soluble agents. The requirement for superoxide anion (O2-) in the production of chemiluminescence is suggested by inhibition (95%) using superoxide dismutase. The results obtained are correlated with those obtained using another method of detecting O2- release (r = 0.61; p less than 0.05) and are also related by regression analysis to polymorphonuclear leucocyte contamination of the alveolar macrophage suspension. This shows that alveolar macrophages produce lucigenin-dependent chemiluminescence of the same order of magnitude as do polymorphonuclear leucocytes.

摘要

本文描述了一种利用光泽精依赖性吞噬化学发光来评估肺泡巨噬细胞对调理素化颗粒或可溶性因子刺激的代谢活性的方法。超氧化物歧化酶抑制作用(95%)表明化学发光产生过程中需要超氧阴离子(O2-)。所获得的结果与使用另一种检测O2-释放的方法所获得的结果相关(r = 0.61;p小于0.05),并且通过回归分析也与肺泡巨噬细胞悬液中的多形核白细胞污染相关。这表明肺泡巨噬细胞产生的光泽精依赖性化学发光与多形核白细胞产生的化学发光量级相同。
