Although a blockade or lack of N-type Ca(2+) channels has been reported to suppress neuronal pathological processes in several animal models of pain and ischemic brain injury, information is still limited regarding the neuroprotective effects of a dual L/N-type Ca(2+) channel blocker, cilnidipine. In this study, we assessed the effects of cilnidipine in the(More)
BACKGROUND/AIMS The L/N-type calcium channel blocker (CCB) cilnidipine has been demonstrated to suppress progressive renal disease in a variety of experimental models, but the characteristic effects of N-type calcium channel blocking action on renal injury have not been examined in detail. Therefore, we investigated the beneficial effects of cilnidipine on(More)
BACKGROUND The L/N-type calcium channel blocker (CCB) cilnidipine has been demonstrated to suppress sympathetic nerve activity. In the present study, we investigated the effects of cilnidipine on the renin-angiotensin-aldosterone system (RAAS) in SHR/Izm rats to confirm differences from the effects of L-type CCB. METHODS Male SHR/Izm rats received(More)
The sympathetic nerve activity plays an important role on the renal function through the vasoactive system and the renin-angiotensin system. Although interest in the renal protective effects of anti-sympathetic agents has been increased, there are not enough data to clarify this efficiency. Therefore, we investigated the effects of L/N-type calcium channel(More)
The trigeminal motor system participates in the control of respiration as well as suckling and mastication. However, the central mechanism underlying respiratory activity in trigeminal motoneurons is not well-understood. In this study, we aimed to elucidate brainstem circuitry for rhythm generation and signal transmission of trigeminal respiratory activity(More)
UNLABELLED The trigeminal motor system is involved in many rhythmic oral-motor behaviors, such as suckling, mastication, swallowing, and breathing. Despite the obvious importance of functional coordination among these rhythmic activities, the system is not well-understood. In the present study, we examined the hypothesis that an interaction between suckling(More)
Because the discoordination between swallowing and respiration may cause severe respiratory disorders such as aspiration pneumonia, understanding the neuronal mechanisms underlying such coordination is important. Recently, it was reported that medullary noradrenergic neurons are involved in evoking esophageal-gastric relaxation reflex, leading to a(More)
Dental surgery performed with high speed instruments, such as a dental turbine, air motor, or micro-engine handpiece, produces a large amount of splattering and particles, which can be contaminated by micro-organisms from the oral cavity. It has been speculated that such particulate mists contain blood-based elements. In the present study, we investigated(More)
We used rat isolated brainstem block preparations to analyze the functional roles of serotonin receptors in the generation of trigeminal rhythmic activities. We previously reported that trigeminal rhythmic activities could be induced by some pharmacological applications in an isolated brainstem preparation with a rostral boundary at the border between the(More)
