本文研究缺氧条件下家兔不同器官组织的氧分压变化,以探讨低氧放射防护效应程度和临床肿瘤低氧放射疗法的应用。1 实验对象:家兔6只,雌雄各半,体重2.2～3.1kg。2 缺氧方法:把家兔置于动物低压舱内以15～20m/s的速度减压致5000m,分别进行不同器官组织氧分压的测量,每种组织测量完毕后,以10m/s速度下降至地面,停留5～10mun待组织氧分压恢复正常后,再上升致终高度进行另一种组织的测量。
This paper studies hypoxia in different organs of rabbits oxygen partial pressure changes in order to explore the degree of hypoxia radiation protection and clinical tumor hypoxia radiation therapy. 1 Experimental subjects: 6 rabbits, male and female, weight 2.2 ~ 3.1kg. 2 Hypoxia method: The rabbits were placed in the animal’s low-pressure cabin at a speed of 15 ~ 20m / s decompression induced to 5000m, respectively, different organ tissue oxygen partial pressure measurement, after each tissue measurement, with 10m / s speed Decreased to the ground, stay 5 ~ 10mun Oxygen pressure to be returned to normal tissue, and then rise to the final height of the measurement of another tissue.
