We characterized muscarinic receptor binding and urodynamic parameters in rats with cerebral infarction and chronic bladder outlet obstruction as models of detrusor overactivity. Bladder weight showed little significant difference between the cerebral-infarcted and sham rats, but the bladder weight
OBJECTIVE
The current study was done to elucidate the in vivo mechanism of action of intravesical instillation of oxybutynin to treat overactive bladder.
METHODS
In rats receiving oral and intravesical oxybutynin we measured muscarinic receptors in the bladder and other tissues by radioligand
In a prospective randomized double-blind study among 50 males undergoing surgery we evaluated the possible role of transdermally applied scopolamine (Scopoderm) in the prevention of post open prostatectomy bladder contraction and pain. Patients were evaluated by subjective report of their pain,
The binding of orally administered imidafenacin, used to treat overactive bladders, to muscarinic receptors in rat tissue was characterized based on pharmacokinetics. The binding in six tissues including bladder tissue was measured using [N-methyl-(3)H] scopolamine methyl chloride ([(3)H]NMS).
Histamine H1-receptors were identified in the guinea-pig urinary bladder. Histamine (10(-8)-10(-3) M) produced a dose-dependent contraction which was not altered by either scopolamine or tetrodotoxin. Specific [3H]mepyramine binding to the urinary bladder was saturable and there was a single
OBJECTIVE
The influence of estrogen on bladder function has been the subject of several experimental and clinical studies. In addition to the well-known estrogen receptor (ER)alpha, recently the ER subtype ERbeta was discovered. We investigated potential changes in bladder function in mice lacking
The effects of capsaicin on urinary bladder function have been investigated in adult rats. Ten days after capsaicin treatment immunocytochemical investigations showed a nearly complete disappearance of substance P (SP) and calcitonin gene-related peptide (CGRP) in all parts of the bladder.
The histamine H2-receptor in the guinea-pig urinary bladder was characterized by determining the effects of histamine and impromidine on contractions induced by electrical transmural stimulation (ETS). The contractile responses to ETS (0.5 ms, 15 V, for 15 s) at frequencies of 1 to 30 Hz were
BACKGROUND
Urinary incontinence is caused by an overactive bladder, leading to symptoms of urgency, frequency, and incontinence. Urge incontinence occurs predominantly in women as they age.
OBJECTIVE
This article reviews the current primary literature concerning the efficacy and tolerability of the
We investigated the nature of the muscarinic receptors present in the rat urinary bladder by performing binding studies with various selective (pirenzepine, AF-DX 116, hexahydrosiladifenidol, benzhexol, 4-diphenyl-acetoxy-N-methyl piperidine methiodide, dicyclomine, secoverine) and classical
Solifenacin is an antimuscarinic agent used to treat symptoms of overactive bladder. Pharmacologically significant amounts of solifenacin were excreted in the urine of humans taking a clinical dose of this drug. The aim of this study is to measure muscarinic receptor binding in the bladder
The regional blood flow of the urinary bladder of rabbits was measured by electrochemically generated hydrogen gas. Then the effects of increased bladder capacity, and of systemic administration of scopolamine and neostigmine bromide on regional blood flow were examined. The local blood flow of the
The development of nerve-induced activation, receptor properties and cellular signalling was examined by comparing the urinary bladder of new-born (0-2 days) and adult mice. Tissue strips were isolated and the effects of different neuromuscular agents on force were investigated during electrical
The mammalian urinary bladder receives dual innervation. The excitatory innervation is considered to be partly cholinergic and partly mediated via NANC-receptors. Several (co-)transmitters have been suggested. The adrenergic inhibitory innervation is mediated via alpha- and beta-receptors. Female
