Abstract

The nuclear bodies of the lymphatic organs were examined in the healthy mice, cats, dogs, sheep, cows, horses and ass with the aim of clarifying species-differences of the bodies. Their structural variation was due to the presence of two kinds of granular elements or vacuoles, and to the distinctness of the separation between the filamentous and granular ones. By the combination of both classifications, 11 types of nuclear bodies were distinguished. The separation between filamentous and granular components was distinct in the nuclear bodies of the mice, cats and dogs, incomplete in those of the sheep and cows, and both components were so heavily intermingled with each other in those of the horses and ass. There are further specific features in some species ; in the cat, the outer filamentous coat of the bodies was thinner than that of other animals. In the dogs, most of the central cores of the bodies were composed of only a spherical mass of dense granules. In the sheep and cows, the nuclear bodies often have a semilunar mass of dense granules in their central cores. In the mice and cats, the number of the nuclear bodies per nucleus was more numerous than that in other animals. The usual patterns of the bodies were constituted with both filamentous and granular elements, and the bodies which are composed of only fiilaments or include vacuoles were rarely found. The nuclear bodies showed a close relationship with the nucleolus in some cells.
