For elucidation of lymphocyte release into the lymph, the lymphatics and their wall in the splenic white pulp and intestinal lymph nodules were examined by transmission and scanning electron microscopy. 1. Lymphatic capillaries were observed to be accompanied with pulp arteries in the human and monkey spleen. The wall of capillaries was a thin layer of endothelial cytoplasm, through which lymphocytes and large wondering cells in the reticular space extend their processes.2. The lining wall of lymphatic sinus surrounding intestinal lymph nodules was (1) composed of a thin cytoplasmic layer of endothelial cells and a fibrillated layer with pores, in which wondering cells existed, and (2) associated with contractile elements, such as elastic fibers and smooth muscle cells, which were disseminated in the vicinity of nodules or fasciculated in the connective tissue. Nerve terminals with cored vesicles were also observed. Intraepithelial occurrence of thread-like basement membranes was observed in the internodular mucosa lining the epithelial fovea on the lymph nodule in the rabbit caecum.

为了阐明淋巴细胞释放到淋巴中，用透射和扫描电子显微镜检查脾白色髓和肠淋巴结中的淋巴细胞及其壁。1.在人和猴脾脏中观察到毛细淋巴管与髓动脉伴行。毛细血管壁是一层内皮细胞质，网状间隙内的淋巴细胞和大的游走细胞通过毛细血管壁伸出其突起.肠淋巴结周围淋巴窦的内壁由内皮细胞胞质薄层和纤维层组成，纤维层内有许多小孔，小孔内有许多奇异细胞;淋巴窦内壁有弹性纤维和平滑肌细胞等收缩成分，分布在淋巴结附近或成束分布在结缔组织中。还观察到具有核心囊泡的神经末梢。在兔盲肠淋巴结的上皮凹内，淋巴结间粘膜上皮内有线状基底膜。
