The effects of valproate (VPA), zonisamide (ZNS), and phenytoin (PHT) on flurothyl (FE)-induced generalized seizure were investigated in mice. In the FE kindling model, eight daily FE-induced generalized clonic seizures followed by a 28-day stimulation-free interval converted the type of seizure expressed in response to FE from clonic to tonic. In an acute(More)
The blood-brain barrier (BBB) is formed by brain endothelial cells. Many immortalized brain endothelial cell lines have been established; these have been used as in vitro BBB models. The aim of the present study was to assess the paracellular barrier properties of the immortalized mouse brain endothelial cell lines bEND.3, bEND.5 cells, and mouse brain(More)
Cytomegalovirus (CMV) remains the most important pathogen following solid organ transplantation and is the major cause of recipient morbidity and mortality during the first 6 months posttransplantation. To prevent CMV infection and/or to prevent symptomatic CMV disease, immunoglobulin (Ig) G including hyperimmune CMV IgG are used alone or in combination(More)
Ischemia-induced hyperactivity is recognized several hours after both common carotid arteries' occlusion for 5 min in Mongolian gerbils, and it continues for at least 7 days. The aim of this study is to investigate the possible mechanisms of this abnormal behavior. Methamphetamine (MAP) (1 and 3 mg /kg) was administered for 7 days and imipramine (IMP) (5(More)
RATIONALE Acute physical dependence refers to the withdrawal syndrome precipitated by an opioid antagonist administered several hours after either a single dose or a short-term infusion of an opioid agonist. OBJECTIVES We examined the mechanism of nicotine-induced attenuation of naloxone-precipitated withdrawal syndrome when used to produce an aversive(More)
When teicoplanin (TEIC) is injected at the maintenance dose, a long period is required for achievement of the target plasma trough concentration because of its long elimination half-life. An initial loading dose is necessary for rapid achievement of an effective plasma trough concentration. Thus, we proposed that it is necessary for a pharmacist determine(More)
We developed a rapid and simple method for identifying 25 commonly used organophosphorus insecticides in human serum using high-performance thin-layer chromatography (HPTLC). These organophosphates were separated on plates with three different developing systems within 6-18 min and detected by means of ultraviolet radiation and coloring reactions with(More)
Brain pericytes are involved in neurovascular dysfunction, neurodegeneration and/or neuroinflammation. In the present study, we focused on the proinflammatory properties of brain pericytes to understand their participation in the induction of inflammation at the neurovascular unit (NVU). The NVU comprises different cell types, namely, brain microvascular(More)
The role of angiotensin (Ang) in neurotransmission of calcitonin gene-related peptide (CGRP)-containing vasodilator nerves in perfused mesenteric vascular beds isolated from spontaneously hypertensive rats (SHR) (8- and 15-week-old) and age-matched Wistar Kyoto rats (WKY) was investigated. In both SHR and WKY preparations precontracted by continuous(More)
The simultaneous determination of zonisamide, a new type of antiepileptic drug, and the typical antiepileptic drugs phenobarbital, phenytoin and carbamazepine in human serum was developed using micellar electrokinetic capillary chromatography (MECC) with a diode array detector. A high correlation was revealed between the zonisamide levels in human serum(More)
