    Abstract:
    The influence of 1-éburnamonine (1-E) and vincamine (Vi) on 2,3-disphosphoglycerate (2,3-DPG) blood level was investigated in awake rats when cyanide (KCN) induced hypoxia was present or not. Used alone, KCN, 1-E and Vi (i.p. route) increased 2,3-DPG blood level. Used with KCN, 1-E or Vi produced a very more important increase of 2,3-DPG than that observed when both drugs were used alone. In all cases, the observed increase was attributed to red cells 2,3-DPG since hematocrite, red-cells count and hemoglobin level were unmodified. The results suggest that the KCN induced increase of 2,3-DPG constitutes a response to hypoxia. On the contrary, that of 1-E or Vi seems to be the result of a metabolic stimulation and could explain in part their antihypoxic properties previously described at cerebral level.
