小儿急性肺炎时,巨噬细胞系统状态在免疫学中具有相当重要的地位,对于单核细胞的功能和各种防卫反应的研究仍是主要课题。作者观察72例1个月一3岁急性肺炎住院患儿,其中14例为单纯型,26例有合并心肺、中毒和循环表现,32例为化脓性肺炎。全部患儿除进行一般临床检查外,分别在疾病的急性期、好转期和恢复期进行外周血单核细胞的流浪酸脱氢酶(SDH),髓过氧化物 In pediatric acute pneumonia, the state of macrophage system plays a very important role in immunology. The research on the function of monocytes and various defensive responses remains a major issue. The authors observed 72 children aged 1 months to 3 years with acute pneumonia hospitalized, of which 14 were simple type, 26 patients had combined cardiopulmonary, toxic and circulatory manifestations, 32 cases of suppurative pneumonia. All children in addition to the general clinical examination, respectively, in the acute phase of the disease, the transition and recovery of peripheral blood mononuclear sour acid dehydrogenase (SDH), myeloperoxide
