作者从14例瘤型麻风的神经取活组织检查,其中13例取自挠神经的皮枝,1例取自耳大神经。将神经制成超薄切片,用枸橼酸铅和醋酸氧铀染色后,作电子显微镜观察。大多数病例的神经实质,部分地被胶原纤维、巨噬细胞、浆细胞、淋巴细胞和纤维母细胞所取代;而少数病例的神经实质则大部分为胶原纤维与上述各细胞所代替。与轴突在一起的神经 The authors examined the biopsies from 14 patients with leprosy, of which 13 were taken from the dermis of the flexible nerve and 1 from the large auricular nerve. The nerves were made into thin sections and stained with lead citrate and uranyl acetate for electron microscopy. In most cases, the neurological substance was partially replaced by collagen fibers, macrophages, plasma cells, lymphocytes and fibroblasts. In a minority of cases, the majority of the neurons were replaced by collagen fibers and the above-mentioned cells. Nerve with axons
