Abstract

Measurements of cerebral blood flow (CBF) were performed using the microsphere technique in non-human primates (baboons) to assess the effect of non-radioactive xenon gas inhalation on CBF. Blood flows in small tissue volumes (approximately 1 cm3) were directly measured before and during the inhalation of xenon/oxygen gas mixtures. The results of these studies demonstrated that when inhaled in relatively high concentrations, xenon gas does increase CBF, but the changes are more global than tissue-specific. The problems and limitations of such evaluations are discussed.

摘要

在非人类灵长类动物(狒狒)中使用微球技术测量脑血流量(CBF),以评估吸入非放射性氙气对CBF的影响。在吸入氙气/氧气混合气体之前和期间,直接测量小组织体积(约1立方厘米)中的血流量。这些研究结果表明,当以相对高的浓度吸入时,氙气确实会增加CBF,但这种变化更具全局性而非组织特异性。讨论了此类评估的问题和局限性。
