In the current Internet system, there are many problems using anonymity of the network communication such as personal information leak and crimes using the Internet system. This is why TCP/IP protocol used in Internet system does not have the user identification information on the communication data, and it is difficult to supervise the user performing the(More)
As development of highspeed network, intelligent multimedia workstation and large-scale storage device technologies, distributed multimedia information services are now making their appearance. However, despite the int,ense media attention currently being showered on multimedia, many obstacles remain to be overcome before practical, widespread applications(More)
In the light of increasing evidence that benign prostatic hyperplasia is associated with cardiovascular disease, we have investigated the relationship between prostatic blood flow and prostatic hyperplasia in the spontaneously-hypertensive-rat (SHR). Twelve-week-old male SHRs were treated with nicorandil for six weeks. Wistar-Kyoto rats were used as(More)
PURPOSE The aim of this study was to investigate the effects of an anandamide transporter inhibitor that can increase endogenous anandamide concentration on the micturition reflex in urethane-anesthetized rats. METHODS Continuous cystometrograms were performed in female Sprague-Dawley rats under urethane anesthesia. After stable micturition cycles were(More)
Previously, we reported that central administration of bombesin, a stress-related peptide, elevated plasma levels of catecholamines (noradrenaline and adrenaline) in the rat. The sympatho-adrenomedullary system, which is an important component of stress responses, can be regulated by the central opioid system. In the present study, therefore, we examined(More)
We previously reported that intracerebroventricularly (i.c.v.) administered (±)-epibatidine (1, 5 or 10 nmol/animal), a nicotinic acetylcholine receptor agonist, dose-dependently induced secretion of noradrenaline and adrenaline (catecholamines) from the rat adrenal medulla by brain diacylglycerol lipase- (DGL), monoacylglycerol lipase- (MGL) and(More)
BACKGROUND A decreased prostatic blood flow could be one of the risk factors for benign prostatic hyperplasia/benign prostatic enlargement. The spontaneously hypertensive rat (SHR) shows a chronic prostatic ischemia and hyperplastic morphological abnormalities in the ventral prostate. The effect of silodosin, a selective alpha1A-adrenoceptor antagonist, was(More)
