The purpose of the present study was to characterize the effect of a local GABAergic inhibitory mechanism on the mechanical receptive field properties of trigeminal spinal nucleus caudalis (SpVc) neurons by iontophoretic application of a gamma-aminobutyric acidA (GABA(A))-antagonist and -agonist. A total of 24 SpVc neurons that responded to orofacial(More)
We examined whether 8-bromo-cAMP (8-Br-cAMP)-induced modification of tetrodotoxin-resistant (TTX-R) sodium current in neonatal rat nodose ganglion neurons is mediated by the activation of protein kinase A (PKA) and/or protein kinase C (PKC). In 8-Br-cAMP applications ranging from 0.001 to 1.0mM, 8-Br-cAMP at 0.1mM showed a maximal increase in the peak TTX-R(More)
The aim of this study was to evaluate the efficacy and tolerability of gefitinib ('IRESSA') in Japanese patients with previously untreated stage IV non-small-cell lung cancer (NSCLC). This was a multi-institutional phase II study. Thirty-four patients with previously untreated stage IV NSCLC were enrolled between May 2003 and September 2004. Gefitinib was(More)
The aim of this study was to test the hypothesis that temporomandibular joint (TMJ) inflammation alters the excitability of trigeminal root ganglion (TRG) neurons innervating the facial skin, by using behavioral, electrophysiological, molecular, and immunohistochemical approaches. Complete Freund's adjuvant (CFA) was injected into the rat TMJ to produce(More)
The aim of the study was to examine the effects of alpha(2)-adrenoreceptor agonists on the excitability of trigeminal root ganglion (TRG) neurons using the perforated patch-clamp technique, and to determine whether these neurons express mRNA for alpha(2)-adrenoreceptors. In current-clamp mode, the resting membrane potential was -57.4+/-1.2 mV (n=26). Most(More)
BACKGROUND This randomised, open-label, multicenter phase II study compared progression-free survival (PFS) of S-1 plus oxaliplatin (SOX) with that of S-1 alone in patients with gemcitabine-refractory pancreatic cancer. METHODS Patients with confirmed progressive disease following the first-line treatment with a gemcitabine-based regimen were randomised(More)
Combined use of magnetoencephalography (MEG), functional magnetic resonance imaging (f-MRI), and motor evoked potentials (MEPs) was carried out on one patient in an attempt to localise precisely a structural lesion to the central sulcus. A small cyst in the right frontoparietal region was thought to be the cause of generalised seizures in an otherwise(More)
Peripheral tissue injury/inflammation can alter the properties of somatic sensory pathways, resulting in behavioral hypersensitivity and pathological and/or chronic pain, including increased responses to pain caused by both noxious stimuli (hyperalgesia) and normally innocuous stimuli (allodynia). Although there are increasing reports that glia in the(More)
Peripheral nerve injury activates satellite cells to produce interleukin 1beta (IL-1beta) which mediates inflammation and hyperalgesia. This study investigated the hypothesis that activation of satellite glial cells modulates the excitability of trigeminal ganglion (TRG) neurons via IL-1beta following inflammation. Inflammation was induced by injection of(More)
The present study investigated whether under in vivo conditions, inflammation alters the excitability of nociceptive Adelta-trigeminal ganglion (TRG) neurons innervating the facial skin via a cytokine paracrine mechanism. We used extracellular electrophysiological recording with multibarrel-electrodes in this study, and complete Freund's adjuvant (CFA) was(More)
