OBJECTIVE
Antimuscarinics improve detrusor overactivity. We evaluated the effects and action mechanisms of imidafenacin (Kyorin Pharmaceutical, Tokyo, Japan), a novel therapeutic agent for overactive bladder with antimuscarinic activity, on mediator release from urothelium and detrusor overactivity
BACKGROUND Augmented cardiac sympathetic afferent reflex (CSAR) plays a role in enhanced sympathetic activity. Given that a strategy for abolishing augmented CSAR-induced sympathetic activation may be beneficial for protecting against ventricular arrhythmias (VAs) triggered by acute myocardial
Chronic sympathoexcitation is implicated in ventricular arrhythmogenesis (VAs) following myocardial infarction (MI), but the critical neural pathways involved are not well understood. Cardiac adrenergic function is partly regulated by sympathetic afferent reflexes, transduced by spinal afferent
OBJECTIVE
There are some reports that bladder C-fibers are partially involved in detrusor overactivity in patients with brain lesions. We investigated the contribution of bladder C-fiber to decreased bladder capacity in rats with cerebral infarction.
METHODS
Cerebral infarction was induced under
OBJECTIVE
Cyclooxygenase inhibitors decrease micturition frequency in animals with bladder inflammation but to our knowledge the influence of cyclooxygenase inhibitors on detrusor overactivity has not been investigated. We evaluated the effects, and the site and mechanism of action of cyclooxygenase
OBJECTIVE
In the present study, we used animal models to investigate whether the selective α(1A)-blocker silodosin exerts inhibitory effects on detrusor overactivity by modulating C-fiber afferent activity.
METHODS
To desensitize C-fiber afferents, 0.3 mg/kg of resiniferatoxin (RTX) was
Findings from prior investigations show that left stellate ganglion (LSG) inhibitory approaches protect the heart from ventricular arrhythmias (VAs) caused by acute myocardial infarction (AMI), which still remain many side effects. Targeted transient receptor potential vanilloid OBJECTIVE
To investigate the efficacy and safety of a combination treatment with α(1)-blockers and antimuscarinics for detrusor overactivity in rats.
METHODS
Rats with detrusor overactivity caused by a cerebral infarction were divided into four groups that received an i.v. administration of
OBJECTIVE
We determined whether the effects of antimuscarinics depend on the suppression of C-fiber bladder afferent nerves. We administered tolterodine intravenously or intravesically.
METHODS
To induce C-fiber bladder afferent nerve desensitization resiniferatoxin (RTX) (0.3 mg/kg) was injected
The enhanced cardiac sympathetic afferent reflex (CSAR) contributes to the exaggerated sympathoexcitation in chronic heart failure (CHF). Increased sympathoexcitation is positively related to mortality in patients with CHF. However, the potential beneficial effects of chronic CSAR deletion on
OBJECTIVE
Alpha1-blockers improve voiding symptoms through the reduction of prostatic and urethral smooth muscle tone; however, the underlying mechanism of improvement of storage symptoms is not known. Using a rat model of detrusor overactivity caused by cerebral infarction (CI), we undertook the
