BACKGROUND AND PURPOSE Nicorandil, an ATP-sensitive potassium (K(ATP) ) channel opener and nitric oxide donor, is used in the treatment of angina and acute heart failure. Here we investigated the effects of two K(ATP) channel openers, nicorandil and cromakalim on ischaemia reperfusion (I-R) injury in the kidney. EXPERIMENTAL APPROACH Right nephrectomy was(More)
INTRODUCTION Diabetes mellitus (DM) represents a major risk factor for erectile dysfunction (ED). Although the etiology of diabetes-induced ED is multifactorial and still unknown, reactive oxygen species are thought to be one of the key factors. AIM The aim of this article is to investigate whether administration of edaravone, a free radical scavenger,(More)
As there is increasing evidence that Rho-Rho kinase (ROCK) pathway plays an important role in the proliferation and contraction in many tissues, we investigated the contractile role of a ROCK inhibitor, fasudil, and the distribution of RhoA, RhoB, RhoC, ROCK1, and ROCK2 in the rat prostate. Twelve-week-old Sprague-Dawley rat prostate was used in this study.(More)
AIMS There is increasing evidence that ischemia is one of the main etiology in overactive bladder (OAB), and that nicorandil prevents OAB. We investigated the effect of nicorandil on hypertension-related bladder dysfunction in spontaneously hypertensive rats (SHRs). METHODS Twelve-week-old SHRs received six-weeks treatment with nicorandil (0, 3, or 10(More)
Hypertension represents a major risk factor for erectile dysfunction. Although the etiology of hypertension-induced erectile dysfunction is multifactorial and still unknown, Rho-Rho kinase pathway is one of the key factors. To investigate whether administration of hydroxyfasudil, a Rho kinase inhibitor could prevent dysfunction of NO-induced relaxation in(More)
We investigated the effects of fasudil, a Rho kinase inhibitor, in the endothelial dysfunction of aortas from spontaneously hypertensive rats (SHRs). SHRs were divided in three groups; intraperitoneally (i.p.) vehicle-treated SHRs (SHR), SHRs treated with fasudil 3 mg/kg i.p. (Fas3), and SHRs treated with fasudil 10 mg/kg i.p. (Fas10). Vehicle-treated(More)
UNLABELLED What's known on the subject? and What does the study add? Acute urinary retention (AUR) and catheterization for AUR (AURC) or drainage of the urine is a well established cause of bladder dysfunction. Previously, we reported that the induction of AURC significantly reduced contractile responses to both carbachol and KCl compared with a control(More)
As increasing evidence suggest that oxidative stress plays an important role in the developing angiopathy in diabetes, we studied the effects of taurine, a free radical scavenger, on diabetes induced angiopathy in the rat aorta. Six-week-old male Wistar rats were randomly divided into three groups; control group (Cont), diabetes group (DM) and diabetes(More)
PURPOSE As hypertension (HT) is one of the risk factors for lower urinary tract symptoms, we investigated the effect of an angiotensin II type I receptor blocker, olmesartan, on bladder dysfunction in the spontaneously hypertensive rat (SHR). MATERIALS AND METHODS Twelve-week-old male SHRs were administered perorally with olmesartan (0, 1, or 3 mg/kg/day)(More)
PURPOSE As increasing evidence suggest that α(1)-blockers prevent benign prostatic hyperplasia related overactive bladder and nocturia in the human, we investigated the effects of silodosin and naftopidil on hypertension-related bladder dysfunction in the spontaneously hypertensive rat (SHR) model. MATERIALS AND METHODS Twelve-week-old male SHRs received(More)
