The effect of the iontophoresis of ascorbic acid (Vitamin C; VC) derivative with frequent-reversal bipolar electric stimulation on the production of collagen in rat skin was evaluated in terms of hydroxyproline content through high-performance liquid chromatography. First, a control group was not given electrical stimulation and four groups were stimulated(More)
Inhibitory effects of docosahexaenoic acid (DHA) on blood vessel contractions induced by various constrictor stimulants were investigated in the rat thoracic aorta. The inhibitory effects of DHA were also compared with those of eicosapentaenoic acid (EPA) and linoleic acid (LA). DHA exhibited a strong inhibitory effect on the sustained contractions induced(More)
Using canine coronary artery ligation/reperfusion and adrenaline arrhythmia models, we determined the effects of azimilide, a class III antiarrhythmic agent, E-1-[[(5-(4-chlorophenyl)-2-furanyl) methylene]-amino]-3-[4-(4-methyl-1-piperazinyl)butyl]-2,4-imidazolidi nedione dihydrochloride. The coronary ligation/reperfusion arrhythmia experiments were divided(More)
Distigmine is a cholinesterase (ChE) inhibitor used for the treatment of detrusor underactivity in Japan. Distigmine's pharmacological effects are known to be long-lasting, but the duration of its effect on urinary bladder contractile function has not been fully elucidated. The present study aimed to determine these effects in relation to the plasma(More)
Distigmine bromide (distigmine), a reversible, long-lasting cholinesterase (ChE) inhibitor, is used for the treatment of underactive bladder in Japan and has been shown to potentiate urinary bladder (UB) contractility. We studied the duration of distigmine's potentiating effects on acetylcholine (ACh)-induced UB contraction and its inhibitory effects on ChE(More)
Distigmine bromide (distigmine), a reversible carbamate cholinesterase inhibitor, is used in Japan for treating detrusor underactivity, myasthenia gravis, and glaucoma. Although there is clinical evidence about the effectiveness of distigmine in the treatment of detrusor underactivity, mechanisms by which distigmine restores impaired urinary bladder smooth(More)
1,3,4,5-Tetrahydro-7,8-dimethoxy-3[3-[[2-(3, 4-dimethoxyphenyl)-ethyl]methylamino]propyl]-2H-3-benzazepin-2-one -hy drochloride (Zatebradine) is a specific bradycardiac agent, blocking the hyperpolarization-activated pacemaker current (I(f)), and thus has no negative inotropic effect. The purpose of this study was to examine whether zatebradine is effective(More)
1Vasodilating effects of prostaglandin E1 incorporated in lipid microspheres (lipo-PGE1) were compared with those of prostaglandin E1 (PGE1) or its cyclodextrin clathrated preparation (PGE1-CD) on plantar skin blood flow in rats treated with tetrodotoxin and N(G)-nitro-L-arginine (L-NNA). Tetrodotoxin (50 microg/kg, i.v.) could totally inhibit the pressor(More)
Effects of DX-9065a ((+)-2S-2-[4-[[(3S)-1-acetimidoyl-3-pyrrolidinyl]oxy]phenyl]-3-[7-amidino-2-naphthyl]propanoic acid hydrochloride pentahydrate), a dibasic propanoic acid and an inhibitor of factor Xa, were compared with those of argatroban, a low molecular weight thrombin inhibitor, on the ellagic acid-induced plantar skin thrombosis in the rats treated(More)
