【摘要】 目的　了解世居高原人群中血浆精氨酸加压素 (argininevasopressin ,AVP)的含量变化 ,初步探讨AVP在高原低氧习服与适应中的作用。方法　采用放射免疫分析法 (RIA)测定世居在海拔 2 2 61,3 840 ,42 80m地区的健康藏族人血浆AVP的含量 (pg/L)。结果　同一年龄段 ,居住在海拔地区的健康藏族人血浆AVP含量升高 (P <0 0 1) ;居住在同一海拔地区的健康藏族人 ,随着年龄的增长 ,血浆AVP含量也升高 (P <0 0 1)。结论　AVP参与了藏族人对高原低氧环境的生物适应过程更多还原

【Abstract】 Objective To study the changes of AVP content in native t ibetans at high altitude and discuss its singnificance in adapting of high altit ude and low oxygen.Methods To use the method of radioimmunoassay(RIA)to sutd y the changes of AVP content(pg/L) in serum of the healthy native tibetans livin g at 2?261,3?840,4?280 meters above sea level.Results AVP content in serum of the native tibetans incre ased with same age and living in altitude upward area( P <0 01).Serum AVP co ntent of the native tibetans increased living in same altitude increased with ag ing( P <0 01).Conclusion AVP helped the native tibetans cope with their environment of high altitude and low oxygen.更多还原
