摘 要: 目的:探讨高氧恢复对低氧训练红细胞参数的影响及其机制。方法:雄性SD大鼠53只,随机分为常氧安静组、常氧训练组、低氧安静组、低氧训练组、常氧训练高氧恢复组、低氧训练高氧恢复组6组。接受不同的处理,4周后测定各组大鼠的Hb、RBC和HCT。结果:常氧运动高氧恢复组血红蛋白的值为各组中最低;低氧运动高氧恢复组血红蛋白值,只与低氧安静组有显著性差异(P<0.05),与其它各组没有明显差异(P>0.05)。各组大鼠的红细胞总数的变化与血红蛋白的变化基本呈现同一规律。而各组大鼠的红细胞压积以低氧安静组最高、常氧安静组最低,但各组间没有显著性差异(P>0.05)。结论:低氧训练后进行高氧恢复在一定程度上降低了SD大鼠的红细胞参数,其机制可能跟高血氧分压抑制机体EPO的分泌等有关。 Objective: to investigate the effect of hyperxia convalescence on parameter of red blood cell of hypoxia training rats. Methods: 53 male adult Sprague-Drawly(SD) rats were randomly divided into 6 groups: normoxia non - exercise group, normoxia exercise group, hypoxia non - exercise group, hypoxia exercise group, normoxia exercise and hyperxia convalescence group, hypoxia exercise and hyperxia convalescence group. After 4 week's training to sample and to test Hb, RBC and HCT of rats. Results: Hemoglobin concentration of normoxiatraining and hyperxia-convalescence group was the lowest of all groups( P 〈 0.05 ). Hemoglobin concentration of hypoxiatraining and hyperxia - convalescence group and was significantly different only compared with hypoxia non - exercise group (P〈0.05). The change of RBC of SDrats almost was the same as the change of Hemoglobin concentration. HCT of every group didn' t show the significant difference( P 〉 0.05), though hypoxia non - exercise group was higher than other groups and normoxia non - exercise group was lower than other groups. Conclusion: Hyperxia convalescence after hypoxia training made parameter of red blood cell of SD rats reduced, and the mechanism may be that hyperxia bate secretion of EPO,
