营养与免疫功能存在着十分密切的关系,营养不良或营养过量均会危及免疫功能,削弱人体的抗病能力。本文就营养缺乏与免疫功能的降低作一简述。一、营养不良与免疫功能降低营养不良,组织学上发现胸腺萎缩并伴有淋巴细胞降低性的胸腺纤维化,淋巴结萎缩,脾中T细胞下降,细胞性免疫功能下降。有人报告4～47个月龄患蛋白质—热量营养不良的婴幼儿尸检后,胸腺重量仅为正常儿童的30～37％,脾重为54～70％,脾生发中心小而少,明显影响着脾和淋巴结的T细胞功能。同时营养不良对植物血凝素(PHA)、刀豆素A、链球菌溶血素和特
Nutrition and immune function are very closely related, malnutrition or excessive nutrition will endanger the immune function, weakening the body’s resistance to disease. This article gives a brief overview of nutritional deficiencies and the reduction of immune function. First, malnutrition and immune function to reduce malnutrition, histologically found thymus atrophy associated with lymphocytopenia thymus fibrosis, lymph node atrophy, spleen T cells decreased cellular immune function decreased. It was reported after 4 to 47 months of age protein - malnutrition infants autopsy, thymus weight is only normal children 30 to 37%, spleen weight 54 to 70%, spleen germinal center smaller and smaller, significantly affected T cell function in the spleen and lymph nodes. At the same time malnutrition on phytohemagglutinin (PHA), concanavalin A, streptolysin and special
