In view of the fact that the detrusor vesicae and external urethral sphincter perform closely synergic functions in micturition, experiments were conducted to explore the action of the pelvic efferent neurons on the external urethral sphincter. The pelvic efferent neurons are generally recognized, by urodynamic assessments and histochemical study with the(More)
PURPOSE To clarify the causative factor underlying rupture of the posterior capsule of the RLC mouse lens as a recessive trait around the 50th postnatal day. METHODS The lenses of the RLC mouse were removed in the period from birth to 50th postnatal day. Some specimens were observed by light microscopy and transmission and scanning electron microscopy.(More)
A new in vitro method was used to examine the initiation and the propagation of the peristaltic contraction in the renal pelvis and ureter of the pig. The method enabled the direct observation of peristalsis, both microscopically and electrophysiologically. A microscopic ripplelike contraction of a constant frequency was generated spontaneously at the(More)
Objective Little is known about the relationship between body composition indicators, including body mass index (BMI), fat mass index (FMI) and lean BMI (LBMI), and adverse outcomes after percutaneous coronary intervention (PCI) in Asian populations. The aim of this study was to clarify this relationship. Methods The SHINANO registry is a prospective,(More)
The subtypes of the muscarinic cholinergic receptor in human detrusor muscle were studied using radioligand binding techniques. It was found that there were significant amount of M1, M2 and M3 receptors labeled by 3H-pirenzepine, 3H-AFDX and 3H-4DAMP, respectively, in human detrusor muscle. The rank order of the amount of these receptors was M3 > M1 > or =(More)
The functional activity of the sphincter muscle of the urethra is known to be controlled largely by the hypogastric and pudendal nerves. It remains unknown, however, whether innervation of the muscle by these peripheral nerves is ipsi- or bilateral. In an attempt to answer this question urethral closure pressure was determined simultaneously in the(More)
