Redox-Sensitive and Folate-Receptor-Mediated Targeting of Cervical Cancer Cells for Photodynamic Therapy Using Nanophotosensitizers Composed of Chlorin e6-Conjugated β-Cyclodextrin via Diselenide Linkage.

The aim of this study was to fabricate a reactive oxygen species (ROS)-sensitive and folate-receptor-targeted nanophotosensitizer for the efficient photodynamic therapy (PDT) of cervical carcinoma cells. Chlorin e6 (Ce6) as a model photosensitizer was conjugated with succinyl β-cyclodextrin via selenocystamine linkages. Folic acid (FA)-poly(ethylene glycol) (PEG) (FA-PEG) conjugates were attached to these conjugates and then FA-PEG-succinyl β-cyclodextrin-selenocystamine-Ce6 (FAPEGbCDseseCe6) conjugates were synthesized.

Efficacy of auditory evoked potential follow-up in viral meningitis of infants.

Purpose: To examine the rate of occurrence of hearing impairments among the infants who had recovered from viral meningitis under 1 year of age through auditory evoked potential (AEP) test and to investigate the efficacy of the follow-up AEP test in viral meningitis infants.

Methods: Two hundred twenty infants (440 ears) were examined through AEP test once, and 47 (94 ears) of them went back for a second examination and were diagnosed with viral meningitis. The first AEP tests were compared with the second results in 47 infants.

Effect of isoflurane versus propofol-remifentanil anesthesia on neuromuscular blockade and hemodynamic responses by cisatracurium bolus injection.

Background: Inhalational anesthetics potentiate nondepolarizing muscle relaxants. Cisatracurium is a recently introduced neuromuscular blocker in Korea. We studied the effect of inhalational anesthesia and total intravenous anesthesia (TIVA) on neuromuscular blockades and hemodynamic responses by cisatracurium bolus injection.

[History and current issues of anesthesia in Korea].

We report the history and current issues of anesthesia in Korea. Korean medical doctors have to take 1-year internship and 4-year residency to be qualified to take the national examination for a board-certified anesthesiologist. The national examination began in 1963, and there were 3,050 board-certified anesthesiologists as of 2006.

Interruption in the supply of breathing gas during general anesthesia due to malposition of the vaporizer -A case report-.

We report a case of interruption in the supply of breathing gas during general anesthesia caused by malposition of the Drager Vapor 2000® vaporizer, which was accidentally tilted and lifted off the Selectatec manifold of the anesthesia machine. Because the patient was an 1-month-old infant, we couldn't check if he had experienced awareness with recall. We emphasize the importance of checking the anesthetic vaporizer after mounting it on the back bar of the anesthesia machine.

Ventricular fibrillation by hypothermia in spinal fusion surgery: A case report.

A 63-year-old man was scheduled for T12-S1 posterolateral spinal fusion surgery. The patient's vital signs were stable and there were no specific laboratory findings except for high triglycerides. In addition, echocardiography showed mild left ventricular hypertrophy, but normal left ventricular function, no regional wall abnormal contractility and normal ejection fraction.
