Abstract:
Objective To observe the fine distribution and morphologic feature of the intrarenal lymphatics. Meth-ods 20 Wistar rats were involved in this study and nephridial tissues were obtained from each animal. Double im-munofluorescence was applied to detect the lymphatic distribution by using Podoplanin and CD34. Renal tissues were obtained from the cortex, medulla and junctional zone,and put in 3% glutaric dialdehyde stationary liquid for transmission electron microscope to observe the fine distribution and morphologic feature of the intrarenal lymphat-ics. Results Under immunofluorescence double staining, lymphatic capillary appeared anomalism, large lumina, thin wall and located in connective tissue region. Cortilymph obviously exceeded medulla lymph in rats. Under e-lectron microscope, the basal lamina of lymphatic was discontinuity. A lot of lysosome and vesicles existed in the endothelial of capillary lymphatics. Many of the vesicles liberated in cytoplasm. The intercellular junctions of the renal lymphatics were held in close apposition. Conclusion The intercellular junctions of the renal lymphatics are held in close apposition by adhesion devices. A lot of lysosomes and vesicles exist in the endothelial of capillary lymphatics, which are the base for renal to transport big molecules and fluids.
