氮代谢的紊乱,可以产生严重的机体自身中毒。氮质血症在临床观察和动物实验中,主要表现为氮化物潴留于血液内,从而刺激机体产生了一系列的全身变化。兹将氮质血症的发生原因、临床现象、发病机制及治疗各方面简要综述于下,并附典型病例加以说明。氮质血症的原因造成氮质血症的原因是多方面的,分述如下: 一肾脏因素健全的肾脏能将蛋白质代谢废物中的非蛋白氮等物质排泄于体外,但当肾机能减退时,尿氮排泄受阻,即可发生血氮潴留。(l)肾原型:由于肾脏本身病变所引发,如慢性血管球性肾炎、肾萎缩、多囊肾、中毒性肾炎及动脉硬
Nitrogen metabolic disorders, can produce serious self-poisoning. Azotemia in clinical observation and animal experiments, mainly for the retention of nitrogen in the blood, thus stimulating the body to produce a series of systemic changes. The azotemia will cause, clinical phenomena, pathogenesis and treatment of all aspects of a brief review, with typical cases to be described. Azotemia cause azotemia due to many reasons, are described below: A kidney with a healthy kidneys protein excretion of non-protein nitrogen waste and other substances excreted in vitro, but when the renal function decline , Urinary nitrogen excretion blocked, can occur blood nitrogen retention. (l) Renal prototype: due to the renal lesions caused by, such as chronic glomerulonephritis, renal atrophy, polycystic kidney disease, toxic nephritis and arterial
