慢性肾衰竭患者由于促红细胞生存素(EPO)生成相对不足,常发生正细胞正色素性贫血,为其特征性表现,是急慢性肾衰竭鉴别的重要参考依据之一。久居高原地区居民血红蛋白正常值较平原居民为高,其原因之一就是由于高原低氧环境,刺激肾脏分泌EPO增加,使红细胞产生增多,发挥代偿的结果 Chronic renal failure due to the relative lack of erythropoietin (EPO) generation, often occurs in orthoporphyrinoid anemia, its characteristic performance, is an important reference for the identification of acute and chronic renal failure. One of the reasons for the high hemoglobin value of residents living in plateau is higher than that of plain residents. One of the reasons for this is that hypoxia in the plateau stimulates the secretion of EPO in the kidneys, increases the production of erythrocytes and compensates
