The facilitatory and inhibitory roles of the ventrolateral medulla in modulating cardiovascular responses elicited from the anterior hypothalamus were studied in urethane-anesthetized rats. Control pressor responses (35-50 mm Hg) were consistently evoked by electrically stimulating the anterior hypothalamic medial preoptic area (AH/POA). The ventrolateral(More)
The macrolide antibiotic bafilomycin A1 is a highly potent and selective inhibitor of all the vacuolar ATPases (V-ATPases). With the aim of obtaining novel analogues specific for the osteoclast subclass of vacuolar ATPase, 31 derivatives of bafilomycin A1 were synthesized and tested for their ability to inhibit differentially the V-ATPase-driven proton(More)
Phenyldiguanide (PDG, 40 microgram/kg), D-ala2-met5-enkephalinamide (D-AME, 250 microgram/kg) and morphine sulfate (MS, 2 mg/kg) injected into the right atrium (RA) of conscious freely moving rats produced a profound bradycardia and hypotension 1-2 sec subsequent to administration. Concomitant with the cardiovascular effects apnea occurred and lasted(More)
