“…In contrast, GFR remained unchanged during infusion of bradykinin. Paradoxically, papaverine reduced GFR as has been previously reported [2,3,6], In the papaverine group, the reduction in GFR coincident with the increase in renal plasma flow led to larger decreases in filtration frac tion than were observed in the bradykinin group. Increases in urine flow were observed in both cases increasing from 0.21 ±0.02 to 0.62±0.16ml/min (p<0.01) during brady kinin infusion and from 0.19 + 0.05 to 0.92±0.38m l/m in (p<0.05) during infu sion of papaverine.…”

“…However, it has not been determined if such an effect occurs in dogs, a species in which Kf appears to be less responsive to various ma nipulations, and glomerular filtration dy namics are not characterized by filtration equilibrium [14][15][16][17][18][19], Thus, experiments were conducted to evaluate the effects of renal intra-arterial infusions of two com monly used vasodilator agents, bradykinin and papaverine, on glomerular filtration dy namics of dogs. These two agents were cho sen since bradykinin usually results in un changed GFR [4,5,[8][9][10] while papaverine mav actually cause decreases in GFR [2,3,6],…”

“…15 These recent observations 12 ' IS and the limitations, i.e., anesthesia and surgical intervention, of the previous studies 5 * 9 prompted an examination of the in vivo renin-releasing properties of saralasin in conscious rats because, in the absence of anesthesia, this species is well suited for studies of the renin-angiotensin-aldosterone axis.…”

“…Chez le chien, la réalisation de velvalopathies tricuspidiennes et pulmonaires (5,6,8,39) ou d'anastomoses artérioveineuses (54, 87), la saignée (73), la perfusion intraveineuse d'adrénaline (16), l'application de stress émotionnels (15) et l'accroissement de la pression dans la veine rénale (13, 187), sont suivis d'une augmentation simultanée de la fraction filtrée et de la réabsorption tubulaire de Na. Inversement, la réduction de la fraction filtrée, obtenue chez l'homme par l'injection intraveineuse de pyrogènes (70, 124) ou de théophylline (38,180) et chez le chien par la perfusion intraveineuse (97,154) ou intrarénale (47,48,77,80,141,206,207,225) de substances vasodila.tatrices telles l'acétylcholine, l'arécholine, la papa- d'une réduction de la réabsorption de Na dans le tube proximal (33,43,81,82,117,122,173,216). L'augmentation de natriurie, toujours inférieure à ce que permet de prévoir la diminution de la réabsorption proximale de Na (43,216), conduit à postuler, au contraire, un accroissement de la réabsorption de Na à des niveaux plus distaux du néphron; cette présomption a été vérifiée par l'expérience (82,122,168).…”

“…Enfin, si la perfusion saline est rapide, le flux médullaire peut être accru sans qu'il y ait d'élution marquée du gradient corticopapillaire (179). Une constatation analogue a été faite par les nombreux auteurs qui ont étudié, chez le chien, les effets de la perfusion de substances vasodilatatrices dans l'artère rénale (47,48,77,80,141,206,207,225).…”
