Electroretinography (ERG) is an effective method for the diagnosis of retinal disease. In the dog, dependable ERG recording is difficult without the use of an expensive device like a Ganzfeld full-field stimulator. The International Society for Clinical Electrophysiology of Vision has defined the standard flash stimulus condition (SF) and evaluation of the(More)
Morning home blood pressure (BP) levels are more closely associated with cardiovascular risk than clinic BP levels. However, control of morning home BP has been worse than that of clinic BP in clinical practice. We examined the effects of olmesartan-based treatment using data (n=21 341) from the first 16 weeks of the Home BP measurement with Olmesartan(More)
Visit-to-visit blood pressure (BP) variability is an important predictor of stroke. However, which antihypertensive drug combination is better at reducing visit-to-visit BP variability and therefore at reducing stroke incidence remains uncertain. We have previously reported that the dihydropyridine calcium channel blocker benidipine combined with a(More)
To investigate the role of the serotonergic nervous system in blood pressure regulation, 5 micrograms of 5-hydroxytryptamine (5-HT) was given i.c.v. before and after 1 microgram of i.c.v. xylamidine or 200 micrograms of i.c.v. ketanserin or 200 micrograms of i.v. ketanserin in conscious Wistar Kyoto rats. Also i.v. (0.5, 1, 2 micrograms) or i.c.v. (1(More)
Recently, the role of the serotonergic nervous system has been implicated in blood pressure regulation and in the pathogenesis of hypertension. However, the effects of 5-hydroxytryptamine (5-HT) administration on hemodynamics have been notoriously inconsistent and the precise mechanism of the blood pressure regulation of the serotonergic nervous system has(More)
Recently, the serotonergic nervous system has been receiving attention, as it participates in the hemodynamic regulation as well as in the pathogenesis of hypertension. The purpose of this experiment is to investigate the role of the central and peripheral serotonergic receptor in the hemodynamic responses induced by intracerebroventricular (i.c.v)(More)
We have previously reported that the intracerebroventricular (i.c.v.) administration of 5-hydroxytryptamine (5-HT) in conscious rats elicited significant pressor response, which was accompanied with an increase in plasma norepinephrine and the pressor response, was abolished by peripheral phenoxybenzamine pretreatment. For further investigation of the(More)
