Interpretation of studies designed to investigate the inhibitory action of vasopressin on gastric acid secretion has proven difficult, as the in vivo models are potentially susceptible to both direct (e.g. mucosal effects) and indirect effects (e.g. changes in mucosal blood flow). In the present series of experiments we studied vasopressin inhibition of(More)
Four standard diuretic compounds were evaluated for electrolyte output, effects on glomerular filtration rate (GFR), and effective renal plasma flow (RPF) in an anaesthetized rat preparation. Triamterene, hydrochlorothiazide, acetazoleamide and furosemide exerted their characteristic diuretic effects at doses which did not significantly change GFR or RPF.(More)
Pentagastrin, histamine, urecholine, DBcAMP, and cGMP were all potent stimulants of acid secretion in the isolated stomach of the fed rat. With the exception of histamine and cGMP, all of these compounds were inactive when the stomach of the fasted rat was used. Pentagastrin was most effective when given on the serosal surface while histamine was equally(More)
