title: [Morphological study of reticulo-epithelial cells in atrophic thymus].
abstract: Anti-keratin and PAP immunohistochemical reaction on atrophic thymus collected from 97 autopsies were studied. Among them, 61 cases belonged to the severs type, whose reticulo-epithelial cells were falling into 4 types: the normal type, the centrally focused type, the diffused type and the depletive type. In 37 out of 61 cases, the reticulo-epithelial cells showed proliferation, especially in the medullary zone. All of 7 cases known as physiological involutional thymus turned to depletive type. 11 cases of atrophic thymus studied by scanning electron microscopy had been classified morphologically into 3 patterns, namely: the reticular form, the honey-combed form and the depletive form respectively.
