BACKGROUND AND OBJECTIVE The aim of the present case series was to examine whether changes in regional cerebral blood flow (rCBF) induced by electroconvulsive therapy (ECT) in the thalamus are related to the efficacy of ECT. Four chronic pain patients with complex regional pain syndrome (CRPS) type-1 (age, 33 to 58 years) who had failed to respond to(More)
BACKGROUND Discogenic pain is an important cause of low back pain (LBP). We have developed a pulsed radiofrequency (PRF) technique, using Diskit II needles (NeuroTherm, Middleton, MA, USA) placed centrally in the disk, for applying radiofrequency current in the disc (Intradiscal PRF method). OBJECTIVE The purpose of this study was to investigate the(More)
BACKGROUND AND PURPOSE The Ca(2+) paradox is an important phenomenon associated with Ca(2+) overload-mediated cellular injury in myocardium. The present study was undertaken to elucidate molecular and cellular mechanisms for the development of the Ca(2+) paradox. EXPERIMENTAL APPROACH Fluorescence imaging was performed on fluo-3 loaded quiescent mouse(More)
The liver innervation of eight different mammalian species was examined by immunohistochemical localization of protein gene product (PGP) 9.5 to visualize the general innervation for autonomic nerve fibres. In addition, dopamine beta-hydroxylase (DBH) and tyrosine hydroxylase (TH), two enzymes involved in catecholamine synthesis, were localized(More)
We investigated the absolute concentration of N-acetylaspartate (NAA) in the thalami of neuropathic pain patients and healthy comparison subjects by single-voxel proton magnetic resonance spectroscopy ((1)H-MRS). (1)H-MRS was performed with a 1.5-T MR system on a voxel in the thalamus bilaterally in 9 neuropathic pain patients and 14 healthy control(More)
We studied capillary endothelial injury, as demonstrated by fibrin deposition and changes in thrombomodulin (Tm) expression, in rats receiving continuous or bolus iv lipopolysaccharide (LPS). Rats were continuously infused with iv LPS (0.1, 0.2, 0.5, or 1.0 mg/kg/hr) for up to 6 hours. Others were given a bolus iv dose of LPS (20 mg/kg), and then the same(More)
BACKGROUND Store-operated Ca(2+) entry (SOCE) has been implicated in various pathological conditions of the heart including ischaemia/reperfusion and ventricular hypertrophy. This study investigated the effects of sevoflurane on SOCE. METHODS Fluorescence imaging was performed on fluo-3- and mag-fluo-4-loaded mouse ventricular myocytes to measure the(More)
BACKGROUND Whereas remifentanil administration is associated with severe bradycardia, it has yet to be fully investigated whether the negative chronotropic action of remifentanil is mediated by its direct action on sinoatrial (SA) node pacemaker activity in the heart versus indirect results of enhanced vagal activity. METHODS We examined the effects of(More)
BACKGROUND Oxidative stress is implicated in pathogenesis of cardiac reperfusion injury, characterized by cellular Ca overload and hypercontracture. Volatile anesthetics protect the heart against reperfusion injury primarily by attenuating Ca overload. This study investigated electrophysiological mechanisms underlying cardioprotective effects of sevoflurane(More)
