[The effect of adenosine receptor agonists on the normal cerebral blood flow and in subsequent ischemia].

Nonconformity of arterial pressure (AP) and cerebral blood flow (CBF) to the normal distribution necessitates the use of nonparametric criteria. Cerebroprotective doses of adenosine and cyclohexyladenosine significantly decrease AP and reduce (or virtually do not change) CBF. In conditions of following occlusion of carotid arteries AP is lower and CBF is somewhat better or the same as in the control (ischemia). Changes in CBF can be only an additional contribution to the high cerebroprotective effect of the A-receptor agonists.
