小鼠腹腔单核巨噬细胞具有贪婪吞噬能力。本文采用同一条件下,不同时间内的组织样品,通过扫描电镜观察其吞噬人红细胞的过程中不同时间的形态变化,同时结合发光测定法测定相应时间的活性氧的释放和能量(ATP)的消耗。得出:巨噬细胞与红细胞接触时(15′—30′),释放活性氧最多,能耗也最大,此后,在红细胞被吞噬过程中(66′—75′)次之。这为吞噬机理的研究打下了基础。 Mice abdominal macrophages have greedy phagocytosis. In this paper, the morphological changes of phagocytosis of human erythrocytes at different time under the same conditions and different time were observed by scanning electron microscopy. The release of active oxygen and the consumption of energy (ATP) at the corresponding time were measured by luminometry . The results showed that when macrophages were contacted with erythrocytes (15’-30 ’), the most reactive oxygen species were released and the energy consumption was also the largest, followed by the process of phagocytosis of red blood cells (66’-75’). This laid the foundation for the study of phagocytosis mechanism.
