抄録: The postnatal growth of the duck spleen was studied histologically, and the relative development of the splenic constituents was estimated by means of microscopic point-counting planimetry in the spleen from the day of hatching up to 22 weeks of age. On the day of hatching, the red pulp showed a relatively high value because of the scant development of white pulp elements ; small areas of periarterial and perivenous lymphoid tissues were present with almost no periellipsoidal lymphoid tissue. Remarkable development of the periellipsoidal lymphoid tissue, however, was ascertained from 3 weeks onward, and this was estimated to be a principal element of the white pulp throughout its postnatal life. India ink particles injected into the blood stream were deposited within the periellipsoidal lymphoid tissues. Germinal centers were firstly noted in the 7 week-old spleen and appeared in the periarterial lymphoid tissue more frequently than in the perivenous lymphoid tissue. These results suggest that the development of the white pulp is completed within several weeks of posthatching life, and that there is a close relationship between the development of the white pulp elements and the immune system in the duck spleen.
