一、序言肾小球毛细血管的特征:1.良好的水和电解质的通透性。2.自白蛋白起始对蛋白质的不透性;因此分子量低于白蛋白的废物可从肾排出,而电解质等一些体内有用的物质再由肾小管重吸收,以保持内环境的恒定。如肾小球受损,由于血流量低下而滤过量低下,且肾小球毛细血管通透性增加,一些在正常尿液中几乎不能见到的白蛋白等物质便排入尿液。尤其在肾病综合征时,尿蛋白高,血中蛋白质浓度减少;由于胶体渗透压降低等而出现浮肿。上述临床症状肾小球毛 I. Preface Glomerular capillary features: 1. Good water and electrolyte permeability. Since the beginning of albumin albumin impermeability; therefore, the molecular weight of less than albumin waste can be discharged from the kidneys, electrolytes and some other useful substances in the body tubular reabsorption to maintain a constant internal environment. Such as glomerular damage, due to low blood flow and low filtration, and glomerular capillary permeability increased, some in normal urine can hardly see the albumin and other substances will be discharged into the urine. Especially in nephrotic syndrome, urinary protein is high, the blood protein concentration decreases; edema due to lower colloid osmotic pressure and so on. The clinical symptoms of glomerular hair
