Dibenamine, 15 mg/kg, injected i.p. in rats anesthetized with ketamine, 60 min before bleeding for 60 min against 40 mm Hg, significantly reduced the severity of kidney lesions. The maximum bleeding volume was reduced by 14%. Adrenalectomy also reduced the bleeding volume but all animals died within 24 hr. In unanesthetized rats bled against 40 mm Hg… (More)
