Macroscopic and histological investigations were made from surgical specimens demonstrating milky spots in the human greater omentum from subjects of various ages. The milky spots in the human greater omentum appear as tiny, cotton-wool-like masses to the naked eye. Histologically, the milky spots consisted mainly of many macrophages with diffuse cytoplasmic esterase reaction products and esterase-negative B lymphocytes surrounding the vascular networks. Macrophages phagocytosed many carbon particles which were introduced as a carbon suspension during the operation. The vascular networks were blood capillary convolutions with a glomerular shape. Silver impregnation showed the delicate networks of reticular fibers which constitute the framework of the organ. The number of milky spots was highest in infancy and gradually decreased with age.
对来自不同年龄段受试者的人网膜中出现乳斑的手术标本进行了大体和组织学研究。人网膜中的乳斑在肉眼下呈现为微小的、棉絮状的团块。组织学上，乳斑主要由许多具有弥漫性细胞质酯酶反应产物的巨噬细胞和围绕血管网络的酯酶阴性B淋巴细胞组成。巨噬细胞吞噬了许多在手术期间作为碳悬浮液引入的碳颗粒。血管网络是呈肾小球状的毛细血管卷曲。银浸染显示了构成器官框架的纤细网状纤维网络。乳斑的数量在婴儿期最高，并随年龄逐渐减少。
