GPIIb/IIIa antagonists are expected to have a beneficial effect on acute cerebral infarction, however, the occurrence of intracranial hemorrhage has not been as widely investigated. A rabbit focal thrombotic occlusion model of the middle cerebral artery was established by creating a photochemical reaction between green light and Rose Bengal. Hemorrhagic(More)
Quick stretching of a helical strip of dog basilar artery at a rate of 10 cm/s to 140% of the slack length of the muscle evoked a delayed contraction. A small amount of hemolysate (0.01-0.2 mg/ml as hemoglobin), which increased the basal tone by 10-15% of the maximum contracture produced by 80 mM K+, potentiated the stretch-induced contraction 2- to 3-fold(More)
Brain-derived neurotrophic factor (BDNF) is a member of the nerve growth factor (NGF) family and has been shown to promote neuronal survival and contribute to neural development. Although methylmercury, a neurotoxin, induces the cell death of neurons in vitro, there is little information regarding the effects of neurotrophins on the methylmercury-induced(More)
Amrinone(5-amino(3,4'-bibyridin)6-(1H)-one), an inhibitor of c-AMP-specific phosphodiesterases, has been used clinically as an inodilator. We have investigated the effect of amrinone on neointimal hyperplasia in rat carotid artery after balloon injury. When amrinone was administered subcutaneously to rats at a dose of 10 mg/kg/day for 14 days, significant(More)
Amrinone, one of the phosphodiesterase III inhibitors, is clinically used for acute heart failure and possesses diuretic action, which is not observed in other phosphodiesterase III inhibitors. To clarify the mechanism of the diuretic action of amrinone, we investigated its effects on renal blood flow and some other hemodynamic parameters in comparison with(More)
Oral administration of the angiotensin AT1 receptor antagonist 3-methyl-2,6-dimethyl-4-[[2'-(1H-tetrazol-5-yl)-1,1'-biphenyl-4-yl ]methoxy] pyridine (ME3221) inhibited the pressor response to angiotensin II at doses of 0.3-1.0 mg/kg in rats. A higher dose of ME3221 (3-10 mg/kg) was required to obtain the same inhibitory potency in dogs. The antagonistic(More)
Pentisomide, 2-(2-diisopropylaminoethyl)-4-methyl-2-(pyridyl)- pentanamide, is a novel antiarrhythmic agent structurally related to disopyramide. Using a glass bead arrhythmic model, the authors studied the antiarrhythmic effect of pentisomide in dogs by monitoring the plasma concentrations. When pentisomide was infused at 1 mg/kg/min for 20 min, the(More)
The pharmacological profile of a new surmountable angiotensin AT1 receptor antagonist, ME3221, 3-methoxy-2,6-dimethyl-4-[[2'-(1H-tetrazol-5-yl)-1,1'-biphenyl-4- yl]methoxy]pyridine, was studied in several animal models, and was compared with that of losartan. EF2831, 3-hydroxy-2,6-dimethyl-4-[[2'-(1H-tetrazol-5-yl)-1,1'-biphenyl-4- yl]methoxy]pyridine, a(More)
