A total of 440 clinically normal children aged from 1 month to 1 year, whose parents are indigenes of the Zabaikalye, were investigated to elucidate the influence of the climatic conditions of the Zabaikalye on the erythrocytic system state. It has been found that the total number of red blood cells, the mean volume of cells containing fetal hemoglobin and methemoglobin, and the number of highly-resistant, i.e. young, red cells, are increased in the children of the Zabaikalye, as compared to those living under conditions of a moderate climate. Methemoglobin reductase activity in them is decreased. The data obtained have evidenced that under conditions of chronic hypoxia erythropoiesis in children living in the Zabaikalye is in the state of high tension.
对440名年龄在1个月至1岁之间、父母为外贝加尔地区原住民的临床正常儿童进行了调查，以阐明外贝加尔地区的气候条件对红细胞系统状态的影响。研究发现，与生活在温和气候条件下的儿童相比，外贝加尔地区儿童的红细胞总数、含有胎儿血红蛋白和高铁血红蛋白的细胞平均体积以及高抗性（即年轻）红细胞数量均有所增加。他们体内的高铁血红蛋白还原酶活性降低。所获得的数据表明，在慢性缺氧条件下，生活在外贝加尔地区的儿童的红细胞生成处于高紧张状态。
