| Research Abstract |
It is well-known that hypoxia and acidosis significantly influence neuronal functions under ischemic conditions. In this study, an electrical activity of spinal neuronal pathways and extracellular purine concentration were measured. Hypoxia and acidosis released not only adenosine but also inosine from the spinal cord, and adenosine suppressed the neuronal activities via adenosine A1 receptors. In addition, the influence of hypoxia largely depended on age, temperature and neuronal pathways. It is suggested that adenosine plays an important role in this phenomenon.
