Leukotrienes (LTs) and lipoxins (LXs) are lipid mediators that play a key role in regulating acute inflammatory responses. Their roles in neural stem cell (NSC) functions are of interest. We showed here that LTB 4 and LXA 4 regulated proliferation and differentiation of murine NSCs that were isolated from embryo brains. Proliferation of NSCs was stimulated(More)
To investigate whether or not NMDA/nitric oxide (NO) pathways in the trigeminal system are involved in the development and/or maintenance of such pathological pain states as the hyperalgesia and allodynia observed after dental surgery, loose-ligation on the left inferior alveolar nerves of rats were performed. The responses to mechanical stimulation were(More)
Cortical spreading depression (CSD) is a transient neuronal and glial depolarization and disruption of membrane ionic gradients that propagates slowly across the cerebral cortex. Recent clinical and experimental evidence has implicated CSD in the pathophysiology of migraines and neuronal injury states. In the current study, we examined the influence of four(More)
Although several risk factors for stroke have been identified, one-third remain unexplained. Here we show that infection with Streptococcus mutans expressing collagen-binding protein (CBP) is a potential risk factor for haemorrhagic stroke. Infection with serotype k S. mutans, but not a standard strain, aggravates cerebral haemorrhage in mice. Serotype k S.(More)
Endocrine disruptors (EDs) are a great concern throughout the world, because they have adverse effects on human health and wildlife. In the present study, we investigated the effects of EDs on the proliferation and survival of murine neural stem cells (NSCs). In contrast to bisphenol A, phthalic acid benzyl n-butyl ester, phthalic acid di-n-butyl ester and(More)
PURPOSE Hypotensive anesthesia with sodium nitroprusside (SNP) often is associated with reflex tachycardia. The purpose of this study was to investigate whether a small bolus of esmolol could counteract SNP-induced reflex tachycardia and sympathetic activation without affecting blood pressure. MATERIALS AND METHODS Using a time-series study design, 27(More)
To investigate the neural mechanism of pain originating from the orofacial region in PD patients, we used PD model rats produced by unilateral injection of 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle. We investigated effects of nigrostriatal lesions on the behavioral response (face rubbing) to formalin injection into the upper lip. We also(More)
Intravenous sedation with propofol is often administered to anxious patients in dental practice. Pain on injection of propofol is a common adverse effect. This study aimed to determine the age-adjusted doses of midazolam required to erase memory of vascular pain of propofol administration and assess whether the Ramsay Sedation Scale (RSS) after the(More)
BACKGROUND Although the peripheral and central sensitizations of trigeminal nervous system may be one of the important factors of migraine, the precise mechanism is not fully understood. In this study, we examined the influence of the sensitization of the second division of the trigeminal nerve (V2) by chronic constriction injury (CCI) of the infraorbital(More)
