[体外研究]

次黄嘌呤是一种潜在的自由基生成剂。次黄嘌呤似乎通过氧自由基产生在缺氧复氧细胞损伤中发挥作用,因此参与许多疾病的发病机理。次黄嘌呤还调节许多其他过程,因为它与苯二氮卓受体反应并抑制大脑中的磷酸二酯酶。次黄嘌呤抑制几种细胞毒性药物的作用,因此可能会影响这些药物的治疗[1]。

[体内研究]

在猪中,发现血浆次黄嘌呤随着低氧血症的持续时间线性增加,并且动脉和静脉血浆之间没有差异。次黄嘌呤和乳酸,碱缺乏和pH之间存在良好的相关性。生存时间与血浆次黄嘌呤的增加之间也存在直接关系。存活时间与次黄嘌呤增加率呈负相关(r = -0.62)。当次黄嘌呤超过125 pM /升时,所有动物死亡。因此,次黄嘌呤的增加反映了急性缺氧的预后与基础缺陷相反[1]。
