BACKGROUND: Laryngoscopy and endotracheal intubation cause hemodynamic changes such as hypertension and tachycardia. Adjuvant fentanyl administration have been used to reduce the hemodynamic changes. Remifentanil, a newly developed ultra short acting opioid, has recently been used to reduce the hemodynamic changes. This study investigated the effects of fentanyl and remifentanil on hemodynamic responses to laryngoscopy and endotracheal intubation. METHODS: Sixth ASA class I or II patients who scheduled for elective surgery were divided randomly into 3 groups. Each patient received normal saline, fentanyl 1.5microgram/kg or remifentanil 1.5microgram/kg, respectively. Predetermined drugs for each group were administered over 30 seconds after induction of anesthesia with TCI of propofol effect site target concentration 4.0microgram/ml and rocuronium 1.0 mg/kg. Laryngoscopy and endotracheal intubation was carried out and systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) were measured baseline (initial), before intubation (BI) and during 5 minutes after intubation (I1 to I5). RESULTS: In the fentanyl group, I1 HR value was significantly higher than baseline. In the remifentanil group, SBP and MAP were significantly lower than baseline during post-intubation period. Fentanyl and remifentanil groups show lesser hemodynamic changes than those in the control group. There were no significant differences of hemodynamic changes between fentanyl and remifentanil group. CONCLUSIONS: Fentanyl and remifentanil can attenuate hemodynamic responses after laryngoscopy and endotracheal intubation.

OBJECTIVE: The purpose of the study was to evaluate the safety and efficacy of tension-free vaginal tape (TVT) placement for surgical treatment of stress urinary incontinence (SUI) in women. METHODS: A retrospective study of 38 cases with SUI underwent the TVT procedure underlying local anesthesia at Daedong and Sewoong Hospital from March 2000 to December 2000, followed up more than six months who included in the study. RESULT: Operation times ranged from 20 to 53 minutes with a mean of 37.5 minutes. The mean blood loss was 90 mL. One major complication was encountered -bladder perforation (2.5%) and urinary retention was developed in 4 cases (10.5%). Length of hospital stay ranged from 0.8 to 11.3 days with a mean of 1.8 days. On postoperative follow-up from 6.1 to 17.5 months, thirty-three patients (87%) were cured, four (10.5%) were significantly improved and one was failed (2.5%). CONCLUSION: Althouth the follow-up period was short, the TVT procedure seemed to be a safe and effective method for the treatment of stress urinary incontience.

BACKGROUND: Mitochondrial trans-2-enoyl-CoA reductase (MECR) is involved in mitochondrial synthesis of fatty acids and is highly expressed in mitochondria. MECR is also known as nuclear receptor binding factor-1, which was originally reported with yeast two-hybrid screening as a binding protein of the nuclear hormone receptor peroxisome proliferator-activated receptor alpha (PPARalpha). However, MECR and PPARalpha are localized at different compartment, mitochondria, and the nucleus, respectively. Therefore, the presence of a cytosolic or nuclear isoform of MECR is necessary for functional interaction between MECR and PPARalpha. METHODS: To identify the expression pattern of MECR and the cytosolic form of MECR (cMECR), we performed reverse transcription polymerase chain reaction (RT-PCR) with various tissue samples from Sprague-Dawley rats. To confirm the interaction between cMECR and PPARalpha, we performed several binding assays such as yeast two-hybrid, coimmunoprecipitation, and bimolecular fluorescence complementation. To observe subcellular localization of these proteins, immunocytochemistry was performed. A luciferase assay was used to measure PPARalpha activity. RESULTS: We provide evidence of an alternatively spliced variant of the rat MECR gene that yields cMECR. The cMECR lacks the N-terminal 76 amino acids of MECR and shows uniform distribution in the cytoplasm and nucleus of HeLa cells. cMECR directly bound PPARalpha in the nucleus and increased PPARalpha-dependent luciferase activity in HeLa cells. CONCLUSION: We found the cytosolic form of MECR (cMECR) was expressed in the cytosolic and/or nuclear region, directly binds with PPARalpha, and enhances PPARalpha activity.

Irritable bowel syndrome (IBS) is a chronic, disabling, and functional bowel disorder that significantly affects social functioning and reduces quality of life and increases social costs. The Korean Society of Neurogastroenterology and Motility published clinical practice guidelines on the management of IBS based on a systematic review of the literature in 2017, and planned to revise these guidelines in light of new evidence on the pathophysiology, diagnosis, and management of IBS. The current revised version of the guidelines is consistent with the previous version and targets adults diagnosed with or suspected of having IBS. These guidelines were developed using a combination of de novo and adaptation methods, with analyses of existing guidelines and discussions within the committee, leading to the identification of key clinical questions. Finally, the guidelines consisted of 22 recommendations, including 3 concerning the definition and risk factors of IBS, 4 regarding diagnostic modalities and strategies, 2 regarding general management, and 13 regarding medical treatment. For each statement, the advantages, disadvantages, and precautions were thoroughly detailed. The modified Delphi method was used to achieve expert consensus to adopt the core recommendations of the guidelines. These guidelines serve as a reference for clinicians (including primary care physicians, general healthcare providers, medical students, residents, and other healthcare professionals) and patients, helping them to make informed decisions regarding IBS management.
