BACKGROUND Glycinergic neurons in the spinal dorsal horn have been implicated in the inhibition of spinal pain processing in peripheral inflammation and chronic pain states. Neuronal isoform glycine transporter-2 (GlyT2) reuptakes presynaptically released glycine and regulates the glycinergic neurotransmission. In this study, we examined whether a selective(More)
Glycinergic transmission has an important role in regulating nociception in the spinal cord. The glycine transporter-2 (GlyT2) is localized at presynaptic terminals of glycinergic neurons and eliminates glycine from the synaptic cleft to terminate glycinergic transmission. Systemic and intrathecal administration of GlyT2 inhibitors alleviate various types(More)
General anesthesia was successfully performed in a 9-year-old boy with FOP. FOP is a very rare inherited disease of the connective tissue, characterized by progressive heterotopic ossification of skeletal muscles, tendons, and ligaments. Trauma and invasive medical procedures can induce heterotopic ossification. Anesthetic concerns for FOP patients include(More)
It has been suggested that store-operated Ca(2+) entry (SOC) facilitates catecholamine secretion and synthesis in bovine adrenal medullary (AM) cells. However, there has been no experimental result clearly showing that cation channel activity is enhanced by store Ca(2+) depletion. Thus the present experiments were undertaken to address the issue of whether(More)
The muscarinic receptor is known to be involved in the acetylcholine-induced secretion of catecholamines in the adrenal medulla (AM) cells of various mammals. The ionic mechanisms, however, have not been elucidated yet. Thus, we investigated the issue in acutely isolated rat AM cells with the perforated patch clamp method. Bath application of 30 muM(More)
BACKGROUND It has been demonstrated that proinflammatory mediators increase in patients with sepsis, trauma, and burns. These mediators are associated with the development of septic shock and organ dysfunction. Dexmedetomidine (DEX), a selective agonist of the α2-adrenergic receptors, is used in intensive care units for sedation. However, it still remains(More)
PURPOSE Taurine is the most abundant amino acid in many tissues. Although taurine has been shown to be antinociceptive, in this report, our focus is to elucidate the mechanism and action site on neuropathic pain. This study used behavioural assessments to determine whether taurine attenuates neuropathic pain in the spinal cord. METHODS Chronic(More)
Chlorogenic acid (CGA), one of the most abundant dietary polyphenols, is known to have various physiological properties. Although CGA is reported to have an antinociceptive effect on acute and inflammatory pain, little is known about its effect on neuropathic pain or its action site. The aim of the present study was to determine whether intrathecally(More)
BACKGROUND Neutrophils play an essential role in innate immunity and against infection. Mitochondria are organelles that produce energy in the form of adenosine triphosphate (ATP), which is required for maintaining the function and structure of cells and organs. Although local anesthetics (LAs) are widely used in clinical practice, it remains unclear(More)
We report the successful management of anesthesia in a patient with stiff-person syndrome (SPS) undergoing a thymectomy using a volatile anesthetic combined with epidural anesthesia. The anesthetic concern in patients with SPS is the possibility of postoperative hypotonia due to the presence of excessive γ-aminobutyric acid (GABA) resulting from an(More)
