毛细血管内的物质及各种药物从血液滤过到肾小球囊腔 ,必须经过由有孔的内皮、基膜和上皮细胞之间裂孔三层结构组成的肾小球滤过屏障 (ｇｌｏｍｅｒｕｌａｒｆｉｌｔｒａｔｉｏｎｂａｒｒｉｅｒ) ,该滤过屏障具有高度的通透性和选择性。在正常情况下 ,血浆中的小分子可溶性物质
Capillary material and various drugs from the blood to the glomerular cavity, must pass through the porous endothelium, basement membrane and epithelial cells between the three-layer structure of the hippocampal filtration barrier (glomerularfiltrationbarrier) The filtration barrier is highly permeable and selective. Under normal conditions, small molecules in the plasma soluble material
