Abstract:
The spatial structure of hemolymph node in the rat is studied by light, transmission and scanning electron microscopy after the fixation of arterial perfusion. The structure of hemolymph node is similar to that of the normal lymph node, and main characteristic is that a number of the red cells are seen in it. The erythrocytes were carried to the afferent lymphatic vessel and reach the medullary sinus, many erythrocytes travel through the rsubcapsula and cortical sinuses, and reach the lymphatic tissue of the local cortex with selectivity, and going through the paracortical zone and the sinus wall to the medulary sinus. Most of the red blood cells are phagocytosed by macrophages in the sinuses. The subcapsular and cortical sinuses of hemolymph nodes connect with medullary sinuses, and form a reticular lymphatic passage. Reticular cells in the sinuses constitute a spatial each other. There are macrophages, lymphocytes, plasmocytes and numerous red blood cells in the nets. Macrophages are anchored on the reticular cells by their pseudopodla, traping and phagocytosing the red cells and foreign matters. Sometimes a macrophage is found closely associated with lymphocytes.
