世界上,伴有感染的蛋白质缺乏性营养不良是儿童慢性衰弱和死亡的最常见原因。而肠道和呼吸道的感染,在生活水平低下地区,又是死亡和长期患病最主要原因,并且可使营养不良小儿迅速变为严重蛋白质缺乏性营养不良。为了防止和减少这些感染的发生。作者从其父母500毫升血液中的5×10~3淋巴细胞中提取的转移因子,对急性感染入院的75例小儿进行了对照观察。 In the world, protein-deficient malnutrition associated with infection is the most common cause of childhood chronic weakness and death. Intestinal and respiratory infections, on the other hand, are among the leading causes of death and long-term morbidity in under-aged areas and can rapidly lead to malnutrition in severely malnourished children. In order to prevent and reduce the occurrence of these infections. The authors compared the transfer factor extracted from 5 × 10 -3 lymphocytes in 500 ml of blood from their parents to 75 children admitted to hospital for acute infection.
