【摘要】：目的研究在進(jìn)入高原前后人外周血血細(xì)胞的變化,分析高原環(huán)境對(duì)人血細(xì)胞的影響。方法通過比較在平原和高原習(xí)服(90 d)后的血細(xì)胞,分析高原環(huán)境對(duì)個(gè)體血細(xì)胞的影響。結(jié)果高原習(xí)服后紅細(xì)胞、血紅蛋白、紅細(xì)胞壓積、平均紅細(xì)胞容積均明顯升高(P0.01),而平均血紅蛋白濃度和平均血紅蛋白含量出現(xiàn)下降(P0.01);進(jìn)入高原90 d后白細(xì)胞計(jì)數(shù)無明顯變化,而淋巴細(xì)胞計(jì)數(shù)和單核細(xì)胞計(jì)數(shù)均有升高(P0.01),中性粒細(xì)胞計(jì)數(shù)下降(P0.01);高原習(xí)服后血小板計(jì)數(shù)顯著升高(P0.01),而血小板體積分布寬度和平均血小板體積則有所下降(P0.01)。結(jié)論高原習(xí)服后血細(xì)胞紅系、淋巴細(xì)胞、單核細(xì)胞、血小板指標(biāo)代償性升高,以滿足機(jī)體對(duì)高原低氧環(huán)境的適應(yīng)。
[Abstract]:Objective to study the changes of human peripheral blood cells before and after entering high altitude and to analyze the effect of altitude environment on human blood cells. Methods the effect of high altitude environment on individual blood cells was analyzed by comparing the blood cells after acclimation at plain and at high altitude (90 d). Results erythrocyte, hemoglobin, hematocrit and mean erythrocyte volume increased significantly after acclimation at high altitude (P0.01), but the mean hemoglobin concentration and mean hemoglobin content decreased (P0.01). After 90 days, the white blood cell count did not change, but the lymphocyte count and monocyte count increased (P0.01), and the neutrophil count decreased (P0.01). Platelet count increased significantly after acclimation at high altitude (P0.01), while platelet volume distribution width and mean platelet volume decreased (P0.01). Conclusion the index of erythrocytes, lymphocytes, monocytes and platelets increased after acclimatization at high altitude in order to satisfy the adaptation of the body to the hypoxia environment at high altitude.
