Familial Mediterranean fever (FMF) is a recessive inherited autoinflammatory syndrome. Patients with FMF have symptoms such as recurrent fever and abdominal pain, sometimes accompanied by arthralgia. Biopsy specimens have revealed substantial neutrophil infiltration into synovia. FMF patients have a mutation in the Mediterranean fever gene, encoding pyrin,(More)
AIMS We investigated the effect of resiniferatoxin (RTX)-treatment on cystometric parameters in the spinal cord injury (SCI) rats in both conscious and urethane-anesthetized conditions and evaluated the influence of urethane-anesthesia on the effect of RTX on lower urinary tract (LUT) function in SCI rats. METHODS Female Sprague-Dawley rats were used. SCI(More)
OBJECTIVE To evaluate the role of the transient receptor potential melastatin 8 (TRPM8) channel on bladder mechanosensory function by using L-menthol, a TRPM8 agonist, and RQ-00203078 (RQ), a selective TRPM8 antagonist. MATERIALS AND METHODS Female Sprague-Dawley rats were used. In conscious cystometry (CMG), the effects of intravesical instillation of(More)
PURPOSE Imidafenacin and fesoterodine are used to treat overactive bladder. Imidafenacin, fesoterodine and its active metabolite 5-hydroxymethyl tolterodine are muscarinic receptor antagonists. It is believed that these agents act on afferent nerves in addition to smooth muscle. We investigated the effects of imidafenacin and 5-hydroxymethyl tolterodine on(More)
OBJECTIVES To investigate single or combined effect of silodosin, an α1A-adrenoceptor antagonist, and imidafenacin, an antimuscarinic agent, on bladder function in a subacute bladder outlet obstruction (BOO) model of male rats. METHODS Partial BOO was created in male Wistar rats by ligating the urethra with a steel rod. On day 10 after surgery, when(More)
OBJECTIVES To clarify the involvement of bladder α1-adrenoceptors (α1-ARs) in afferent pathways by investigating the effects of silodosin and BMY7378, selective α1A- or α1D-AR antagonists, respectively, on single-unit afferent nerve fibre activity (SAA) of the primary bladder afferent nerves and their relationship with bladder microcontractions in rats. (More)
OBJECTIVES We investigated the direct effects of sildenafil, a phosphodiesterase type 5 inhibitor, on the single-unit mechanosensitive afferent activities (SAAs) primarily originated from the bladder in the rat. METHODS Female Sprague-Dawley rats were anesthetized with urethane. SAAs were recorded from the left L6 dorsal roots and classified by conduction(More)
