一、蛋白尿的生成原理当血液流经人体两侧肾脏时,经肾小球滤过后每天约形成180升滤液,滤液中含有蛋白质2～4克。当滤液流经肾小管时,95％以上的蛋白质被肾小管重吸收,故正常人尿中的蛋白质含量很少,每天从尿中排出的蛋白量约40～100毫克,常规尿蛋白定性试验为阴性或微量。如每天尿蛋白排出量持续超过150毫克,即称为蛋白尿。尿蛋白定性试验以+、++、+++、++++表示,相当于100毫升尿中分别含有30毫克、100毫克、300毫克、500～1000毫克以上的蛋白质。蛋白尿的生成机制可能是:肾小球毛细血管通透
First, the principle of the formation of proteinuria When blood flows through the human kidney on both sides of the body after the formation of glomerular filtration about 180 liters of filtrate per day, the filtrate contains 2 to 4 grams of protein. When the filtrate flows through the tubules, more than 95% of the protein is tubular reabsorption, so the normal human urine protein content is small, the daily amount of protein excreted from the urine of about 40 to 100 mg, conventional urine protein qualitative test Negative or trace. Such as urinary protein excretion per day more than 150 mg, known as proteinuria. Urinary protein qualitative test to +, ++, +++, ++++ said that equivalent to 100 ml of urine, respectively, containing 30 mg, 100 mg, 300 mg, 500 to 1000 mg of protein. The mechanism of proteinuria may be: glomerular capillary permeability
