• Cytological studies on the lymphoid cells in lymph node of EIA were carried out based upon patho-morphology employing phase microscope. In these studies, the "so-called lymphoid cells" were examined cytologically, dividing them into large and small lymphoid cells, and further classifying the small lymphoid cells provisionally into three sub-types as typical, L-cell-like and plasma-cell-like lymphoid cell from the appearances of the hematoxylin-eosin-stained tissue preparation. As to the results, no essential differences among those small lymphoid cells were recognized under the phase microscope, and it was realized that the lymphoid cells should be distinguished from the lymphocyte. It was impossible to consider that the plasma-cell-like small lymphoid cell resembling the plasma cell on the tissue preparation stained with hematoxylin-eosin was some form of the plasma cell, and that the plasma-cell-like lymphoid cell was a "lymphoid cell." In regard to the "L-cell" described in the first report, it was found that the "L-cell" was akin to the small lymphoid cell, and that it played some role in the increase of lymphocytes from the fact that the enlargement of lymph node in EIA is due not only the hyperplasia of the lymphoid cells but of the lymphocytes. The appearance of the "L-cell" and the small lymphoid cell in peripheral blood under phase microscopic observation indicates that these sorts of cells play a great part in monocytosis and lymphocytosis as pointed out by hematological investigators in the past, The fact mentioned above will arouse some interesting problems in comparative pathology. In conclusion, the author clarified the cytological characteristics of obscurely known "so-called lymphoid cells, " and found some characteristics of occurrence of these kinds of cells in visceral organs and blood. This contributes to clarifying the essential natures of EIA.
