Effect of perindopril on renal medullary blood flow: comparison with other antihypertensive treatments.

Early and chronic angiotensin-converting enzyme (ACE) inhibition in Lyfon hypertensive (LH) rats improves their blunted vasodilator response of renal medullary blood flow (MBF) to angiotensin II (AngII). This study examined the specificity of this effect and the possible involvement of nitric oxide (NO). The renal response to AngII (from 7.
