Conscious rats were exposed to 100% O2 at 2.5 ATA for 90 min for up to 10 consecutive days, or to an N2-O2 mixture (PO2 = 0.3 ATA) under the same conditions (control animals). Cerebrovascular permeability to 14C-sucrose in the experimental animals was not altered by hyperbaric O2 exposure when compared to the value in control animals. These results differ with other reports that similar hyperbaric O2 exposure increases cerebrovascular permeability to ferritin and to a protein enzyme.
清醒大鼠连续10天每天在2.5个绝对大气压下暴露于100%氧气中90分钟，或在相同条件下暴露于氮气 - 氧气混合物（氧分压 = 0.3个绝对大气压）中（对照动物）。与对照动物相比，实验动物中脑血管对14C - 蔗糖的通透性在高压氧暴露后未发生改变。这些结果与其他报告不同，其他报告表明类似的高压氧暴露会增加脑血管对铁蛋白和一种蛋白酶的通透性。
