Antidepressants modulate glycine action in rat hippocampus.

Antidepressants are drugs that relieve symptoms of depressive disorders. Fluoxetine, tianeptine, and milnacipran are different types of antidepressants, and they have widely been used for relieving of depression symptoms. In the present study, the effects of fluoxetine, tianeptine, and milnacipran on the glycine-induced ion current by nystatin-perforated patch clamp and on the amplitude of field potential in the hippocampal CA1 region by multichannel extracellular recording, MED64, system, were studied.

Acute unilateral anesthesia mumps after hysteroscopic surgery under general anesthesia: a case report.

Acute unilateral parotid gland swelling after general anesthesia, anesthesia mumps is rare and when occurred, it is associated with the patient's position and with long-lasting surgery. The exact mechanism or etiology has not been fully established but stasis of gland secretion, blockage of Stensen's duct by direct compression, or retrograde flow of air by increased the oral cavity pressure are suspicious reasons. We experienced a case of soft tissue swelling in the left preauricular and submandibular regions in a 40-year-old female patient after short-lasting, hysteroscopic myomectomy performed in the lithotomy position with no suspicious predisposing factor.

Analysis of expert consultation referrals to the Korean Society of Anesthesiologists (KSA): a comparison of procedural sedation and general anesthesia.

Purpose: Procedural sedation during diagnostic or therapeutic procedures is currently widely used by clinicians across a broad range of specialties. However, procedural sedation is a poorly controlled practice in many countries, often performed in potentially unsafe environments.

Methods: In 2009, the Legislation Committee of the Korean Society of Anesthesiologists, based on expert consultation referrals provided by police departments, civil courts, and criminal courts, initiated the construction of database to compile all anesthesia-related adverse events.

Hepatic ischemic preconditioning provides protection against distant renal ischemia and reperfusion injury in mice.

We previously demonstrated that there are acute and delayed phases of renal protection against renal ischemia and reperfusion (IR) injury with renal ischemic preconditioning (IPC). This study assessed whether hepatic IPC could also reduce distant renal IR injury through the blood stream-mediated supply of reactive oxygen species (ROS). Male C57BL/6 mice were randomly divided into four groups: group I, sham operated including right nephrectomy; group II (IR), left renal ischemia for 30 min and reperfusion injury; group III (IPC-IR), hepatic ischemia for 10 min followed by 10 min of reperfusion before left renal IR injury; group IV (MPG - IPC + IR), pretreated with 100 mg/kg N-(2-mercaptopropionyl)-glycine (MPG) 15 min before hepatic IPC and left renal IR injury.

Low dose ketamine reduces the induction of ERK1/2 and CREB signaling protein in a neuropathic pain model of rats.

Background: In addition to causing the loss of voluntary sensory and motor function, spinal cord injury (SCI) often creates a state of central neuropathic pain. Rats given SCI display increases in the activated form of transcription factors ERK 1/2 MAPK and CREB in the spinal cord, which correspond to allodynia in a model of neuropathic pain. This study was conducted to determine if low dose ketamine had an effect on the activation of ERK 1/2 and CREB in the development of neuropathic pain.

Intrathecal clonidine reduces hypersensitivity after nerve injury by a mechanism involving spinal m4 muscarinic receptors.

Unlabelled: alpha2-Adrenergic agonists reduce mechanical and thermal hypersensitivity in animals with nerve injury and effectively treat neuropathic pain in humans. Previous studies indicate a reliance of alpha2-adrenergic agonists in this setting on spinal cholinergic activation and stimulation of muscarinic receptors. The subtype(s) of muscarinic receptors in the spinal cord that produces antinociception in normal animals is controversial, and those involved in reducing hypersensitivity and interacting with alpha2-adrenergic systems after nerve injury are unstudied.
