Exposure of male Wistar rats to oxygen atmosphere at moderate pressure (1.10-1.15 atm) for 4 h resulted in significant, transient, and reversible decrease in hemolytic resistance of peripheral blood erythrocytes. In 2 days after oxygen exposure, the bone marrow released young erythrocytes with enhanced hemolytic resistance as a compensation for oxygen injury. These findings suggest that normobaric oxygen load can be viewed as a stress factor of moderate intensity.

大鼠暴露于中压氧气环境对红细胞抗溶血能力的影响

雄性 Wistar 大鼠在中等压力 (1.10-1.15 atm) 的氧气环境中暴露 4 小时，导致外周血红细胞溶血阻力显着、短暂和可逆的降低。在氧气暴露后2天，骨髓释放具有增强溶血性的年轻红细胞作为氧损伤的补偿。这些发现表明，常压氧负荷可被视为中等强度的压力因素。
