吞噬细胞杀伤细胞内外病原体的作用,部分地归因于所产生的氧基,即超氧化物、过氧化氢、羟基基团及可能的单分子氧。原虫含有内源性的氧衍生物清除剂,在抵抗吞噬细胞产生的毒性氧基方面可能是重要的,最常 The role of phagocytes in killing both intra- and extracellular pathogens is due in part to the oxygen radicals produced, namely superoxide, hydrogen peroxide, hydroxyl groups and possibly monomolecular oxygen. Protozoa contain endogenous oxygen derivative scavengers that may be important in counteracting toxic oxygen radicals produced by phagocytes, most commonly
