Abstract

The immunohistochemical composition of amyloid deposits in secondary human amyloidosis and experimental amyloidosis in rabbits was studied by means of the "fluorescent antibody" technique of Coons et al. Quantitative studies of the relative amounts of gamma globulin present in the amyloid deposits by the use of radioiodinated fluorescent antibody are reported. It is concluded that amyloid deposits in several organs from cases of secondary human amyloidosis and experimental amyloidosis in rabbits contain considerable concentrations of gamma globulin. The presence of gamma globulin in amyloid might be interpreted as either a metabolic deposition of circulating globulin present in high concentrations in the plasma or as a result of an immunologic reaction involving antigen and antibody.

摘要

采用孔斯等人的“荧光抗体”技术,对继发性人类淀粉样变性和兔实验性淀粉样变性中淀粉样沉积物的免疫组织化学组成进行了研究。报告了使用放射性碘化荧光抗体对淀粉样沉积物中γ球蛋白相对含量的定量研究。得出的结论是,继发性人类淀粉样变性病例和兔实验性淀粉样变性的几个器官中的淀粉样沉积物含有相当浓度的γ球蛋白。淀粉样物质中γ球蛋白的存在可解释为血浆中高浓度循环球蛋白的代谢沉积,或抗原与抗体免疫反应的结果。
