对海拔2880米～4120米地带552名健康移居者进行检测,检出高原性脾肿大34例。结果表明,31～40岁年龄带脾脏增大人数增高明显,随年龄梯度习服者改变,有减少趋势,脾脏改变有个体差异和解剖关系差异。本文认为,高原缺氧红细胞代偿性增多,加重脾脏负担。缺氧直接刺激网状内皮系统增生。血液流变学和动力学改变等因素,引起脾脏肿大。
A total of 552 healthy migrants from 2880 to 4120 meters above sea level were detected and 34 cases of high altitude splenomegaly were detected. The results showed that there was a significant increase in the number of spleen enlargement in the age group of 31-40 years old, with a trend of decreasing with the change of the age-grading habitants. There were individual differences and anatomic differences in spleen changes. This paper argues that plateau hypoxia red blood cells compensatory increase, increase the burden on the spleen. Hypoxia directly stimulates the proliferation of reticuloendothelial system. Hemorheology and kinetic changes and other factors, causing splenomegaly.
