作者以植物血凝素和脂多糖分别激活 T、B 淋巴细胞,应用放射性标记化合物掺入实验,观察了麻风患者的淋巴细胞在转化时大分子合成代谢的变化。此可反映免疫功能。结果现症患者的 T 细胞~(14)C-缬氨酸的掺入显著减少,相反,B 细胞~(14)C 缬氨酸、3H-胸苷和~(14)C-尿苷的掺入均显著增多;接近治愈和治愈的病人 T、B 细胞的放射性掺入均在正常范围.这表明麻风的免疫反应是以细胞免疫为主. The author activates T and B lymphocytes with phytohaemagglutinin and lipopolysaccharide, and incorporates radiolabeled compounds into the experiment to observe the changes in the synthesis and metabolism of macromolecules of lymphocytes in patients with leprosy. This reflects the immune function. Results The incorporation of ~ (14) C-valine in T cells was significantly reduced in patients with concomitant intracerebral hemorrhage. In contrast, incorporation of ~ (14) C valine, 3H-thymidine and ~ (14) All significantly increased, and the radioactive incorporation of T and B cells in the patients who were almost cured and cured were in the normal range, indicating that the immune response of leprosy was mainly cellular immunity.
