The effect of functional impairment of the renin-angiotensin system on the vasoconstriction
mediated by postsynaptic α 1 and α 2 -adrenoceptors in pithed normotensive rats was studied…

Inhibitors of the angiotensin I converting enzyme (captopril, enalapril) offer a new principle
in the drug treatment of hypertension and congestive heart failure. The present survey deals …

The present study characterized the effects of sodium nitroprusside (SNP) on the responsiveness
of pithed rats to pressor stimuli. Intravenous infusions of SNP produced a dose-related …

The effects of chloroquine and some other antimalarials on the immune responses in experimental
animals have been examined. Chloroquine and quinine caused significant decrease …

In pithed rats, but not in pithed cats, the α 2 ‐/dopamine agonist B‐HT 920 (10–300 μg kg −1
) increased cardiac output. The increase was inhibited by yohimbine (1 mg kg −1 ), but not …

1 The influence of angiotensin II (AII) on resting blood pressure and on sympathetic nerve‐mediated
pressor responses in the pithed rat was investigated either by inhibiting the renin‐…

1 The effects of angiotensin II (AII) and Bay K 8644 on responses to noradrenaline (NA)
mediated via postjunctional α 1 ‐ and/or α 2 ‐adrenoceptors have been compared in three …

In the spinal pithed rat, DuP 753, 2-n-butyl-4-chloro-5-hydroxy methyl-i-[(2'-(i H-tetrazol-5-yI)
biphenyl4-yl) methyl] imidazole potassium salt, inhibited competitively the pressor response …
