Cerebral blood flows (CBF) were measured in the parietal cortex, the
thalamus and the cerebellum by the hydrogen clearance technique in
anesthetized spontaneously hypertensive rats, of which hypertension was
treated for 16 weeks (long-term) or 8 weeks (short-term) with
antihypertensive agents of hydralazine and guanethidine. As compared to
non-treated control animals, CBF in the three regions were significantly
increased while the calculated cerebrovascular resistances (CVR) were
decreased in hypertension-treated animals. Such CBF and CVR changes were
greater in SHR with long-term than short-term therapy. Both an increase in
CBF and a decrease in CVR were closely related to a fall in the blood
pressure. From the present results, it was concluded that earlier and
longer treatment of hypertension could lessen or even prevent the increased
CVR due to the hypertensive vascular changes, and increase CBF as a result.
