本文观察高二氧化碳对常压缺氧大鼠血液动力学及肺组织β和α_1受体密度的影响。大鼠置缺氧舱内(O_2=10%,高CO_2组CO_2=2.5%,单纯缺氧组CO_2=0)。间断缺氧1周(6小时/天,6天/周)。右心导管
In this paper, we observed the effects of hypercapnia on hemodynamics and beta and alpha 1 receptor density in hypoxic rats. Rats were housed in anoxic chamber (O_2 = 10%, CO_2 = 2.5% in high CO_2 group and CO_2 = 0 in pure hypoxia group). Intermittent hypoxia for 1 week (6 hours / day, 6 days / week).
