BACKGROUND: The incidence of postoperative nausea and vomiting after cardiac surgery is 30-40%.The role of a nasogastric tube for reducing the PONV is still controversial. METHODS: 92 patients who were undergoing cardiac surgery with cardiopulmonary bypass were randomized to a receive nasogastric tube after induction of anesthesia (Group 2) or they were placed in the control group (no nasogastric tube) (Group 1).The patients with a history of gastric/esophageal surgery, esophageal varix, esophageal stricture and/or a history of antiemetic treatment were excluded.Routine fast-track cardiac anesthesia and postoperative care were employed for all the patients.The incidence of PONV was recorded hourly for the first four hours after extubation and then every 4 h afterwards for 24 h.The usage of antiemetics and pain medication was also recorded.The data was analyzed with t-tests and chi-square tests for the continuous variables and the categorical data, respectively.P values < 0.05 were considered statistically significant. RESULTS: The groups were similar with respect to the demographic data, the surgical characteristics and the opioid usage.There was no significant difference in the incidence of PONV and the antiemetic usage between the two groups. CONCLUSIONS: This study showed that placement of a nasogastric tube did not have an impact on the incidence of PONV or the requirements for antiemetics after cardiac surgery.The results of this study do not support the use of a nasogastric tube to reduce PONV after cardiac surgery.

PURPOSE: To compare T2-weighted MR cholangiography (T2-MRC) and contrast-enhanced T1-weighted MRC (enhanced T1-MRC) in the assessment of biliary anatomy in donor candidates for living related liver transplantation (LRLT). MATERIALS AND METHODS: Thirty-three potential donors underwent MR examination for preoperative evaluation. Using the single-shot half-Fourier RARE sequence, T2-weighted single-section and coronal images were obtained, and enhanced T1-MRC was performed, using 3D GRE sequences after the administration of mangafodifir trisodium. To assess the hilar ductal branching pattern and determine diagnostic confidence, two reviewers first evaluated the unpaired T2-MRC and enhanced T1-MRC images, and then paired T2-MRC and enhanced T1-MRC images together. In particular, in 12 cases in which direct cholangiographys were performed, the feasibility of single duct-to-duct anastomosis was assessed using the unpaired and the paired sets sequentially. RESULTS: The reviewers' confidence tended to be higher for enhanced T1-MRC than T2-MRC, but the difference was not statistically significant. For both reviewers, confidence was significantly higher for the paired set than for T2- or enhanced T1-MRC alone (p < .001). The types of biliary anatomy determined in the paired set matched the consensus reading in 33 (100%) and 30 cases(91%) assessed by reviewer 1 and 2, respectively. The separate interpretation of T2- and enhanced T1-MRC findings matched the consensus interpretation in 30 (91%) and 28 cases (85%), respectively, assessed by reviewer 1, and 26 (79%) and 28 cases (85%), respectively, assessed by reviewer 2. The possibility of single anastomosis was accurately predicted in 91.6% of cases in T2-MRC, and 100% at enhanced T1-MRC and the combined set. CONCLUSION: In the evaluation of the biliary anatomy of potential donors for LRLT, the combined use of T2-MRC and enhanced T1-MRC may improve diagnostic confidence and decrease the occurrence of a non diagnostic or equivocal interpretation at T2-MRC alone.

BACKGROUND: Emergence agitation (EA) in children after sevoflurane anesthesia is common. The purpose of this study was to compare the incidences of EA between ketamine and thiopental sodium induction in children underwent sevoflurane anesthesia. We also evaluated if a small dose of fentanyl could reduce the incidence of EA. METHODS: The patients who were scheduled for strabismus or entropion surgery were divided into 4 groups. The patients in Groups 1 and 2 were induced anesthesia with ketamine 1.5 mg/kg; those in Groups 3 and 4 were induced with thiopental sodium 5 mg/kg. The patients in Groups 1 and 3 received an injection of fentanyl 1.5 microgram/kg, whereas the patients in Groups 2 and 4 received IV saline of the same volume. Anesthesia was maintained with sevoflurane. The recovery characteristics and EA in recovery room were assessed. RESULTS: The incidence of EA was significantly higher in Groups 2 and 4 and there was no difference between Groups 2 and 4. Group 2 had almost an eleven-fold higher risk of developing EA than did Group 1, and the incidence of EA in Group 4 was sixty-nine-fold higher than that of Group 1. The risk factor for EA was only the kind of medication. Preoperative anxiety had no significant correlation with EA. CONCLUSIONS: The incidence of EA after sevoflurane anesthesia is similar between ketamine and thiopental sodium anesthetic induction in children undergoing pediatric ophthalmic surgery. Also, the addition of a small dose of fentanyl after anesthetic induction decreases the incidence of EA.

Mechanical complications of acute myocardial infarction which may lead to heart failure or shock include ruptute of left ventricular free wall, ventricular septum and papillary muscle. The clinical characteristics of these lesions vary conservative management alone has high mortality rate, for which reason surgical repair of these defects are essential. Structural defects including rupture of the left ventricular free wall, ventricular septum, and papillary muscle, accout for 5% to 20% of all deaths from acute myocardial infarction. Among these, ventricular septal defects occur in approximately 1% of all myocardial infarction, and account for up to 2% of deaths subsequent to myocardial infarction. Rupture of the ventricular septum following acute myocardial infarction(AMI) is associated with high mortality rate, as 54% of the patients succumb within two weeks, 87% within two months and 92.5% during the first year. We experienced two cases of postinfarct ventricular septal defects(VSD) which had been repaired within 1 week after AMI due to progressive deterioration of patients` conditions, and were to be reoperated because of repeated septal ruptures in postoperation period and development of cardiogenic shock.

As prediction of rapidly aging society, bone health is considered increasingly important and received more attention than ever. Bone health is regulated by balancing between bone resorptive osteoclasts and bone formative osteoblasts. Disruption of balance between bone-resorbing osteoclasts and bone-forming osteoblasts results in bone disease. Natural products have recently received much attention as an alternative tool for the development of novel therapeutic strategy. Baicalein is reported it has anti-cancer, anti-inflammatory and antioxidant effects. Baicalein also has been known that it has both promotive effect on MC3T3-E1 cell line and inhibitory effect on RAW 264.7 cell line. However, the inhibitory mechanism of baicalein using bone marrow derived macrophages (BMMs) on osteoclast differentiation remains not clear. In this study, the suppressive mechanism by baicalein on osteoblast differentiation was evaluated. Bicalein inhibited receptor activator of nuclear factor-kappaB ligand (RANKL)-induced osteoclast differentiation in BMMs in a dose dependent manner without any toxicity. Baicalein suppressed phosphorylation of protein kinaseB (Akt), c-Jun N-terminal kinases (JNK) and phosphoinositide-specific phospholipaseCgamma2 (PLCgamma2). Furthermore, Baicalein suppressed the induction of RANKL-induced c-Fos and Nuclear factor of activated T cell c1 (NFATc1), essential genes on osteoclastogenesis. In BMMs, Bicalein inhibited the mRNA expression of tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), cathepsinK, dendritic cell-specific transmembrane protein (DC-STAMP). Moreover, baicalein promoted differentiation of osteoblast on bone marrow stromal cells (BMSCs). Taken together, these results suggest that baicalein has a potential for treating bone lytic diseases, such as osteoporosis, periodontitis, and rheumatoid arthritis.

PURPOSE: There are several kinds of classificatian dealing with the staging of the gastric adenocarcinoma. However, such different staging systems pose difficulty in the inter- institutional or intemational comparison of the disease status and the treatment results. The purpose of this study is to evaluate each staging system and to assess the usefulness of the new UICC-TNM staging system (1997) for gastric adenocarcinoma. MATERIAL AND METHODS: We retrospectively analysed 473 cases of gastric adenocarcinoma who were operated at the Department of General Surgery, Hanyang University Hospital during the period from 1992 to 1996. Using these cases, we analyzed their cumulative 5-year survival rate according to three kinds of staging systems; old UICC-TNM staging system (1987), new UICC-TNM staging system (1997), and the Japanese staging system for gastric carcinoma (1993). RESULTS: The follow up rate was 94.3% and the median follow up period was 30.3 months. All of these three systems showed a statistically significant survival difference according to their different classifications. When the distribution of stage between old and new UICC-TNM staging system was compared, 95 cases (20.1%) were subjected to stage shifting, which involves 12.1% of up-staging and 8.4% of down-staging. Stage shifting was most prominent in stage IIIb (68.8%). The cumulative 5-year survival rate according to the new UICC-TNM staging system was 99.1% in stage Ia, 81.4% in stage Ib, 75.2% in stage II, 45.9% in stage IIIa, 21.0% in stage IIIb, and 19.4% in stage IV. CONCLUSION: We conclude that the new UICC-TNM staging system is simple, practically convenient, and highly reproducible, and it showed a statistically significant survival difference according to their staging classification.

The antioxidant activity of white ginseng was not recorded in Korea Functional Food Code, while its activity of red ginsengs was recorded. The aim of this study was to evaluate the antioxidant and hepato protective effect of different ginsengs in H2O2-treated HepG2 cells. White and red ginseng were prepared from longitudinal section of the same fresh ginseng (4-year old). The whole parts of white and red ginsengs were separately extracted with 70% ethanol and distilled water respectively, at 70 degrees C to obtain therapeutic ginseng extracts namely, WDH (distilled water extract of white ginseng), WEH (70% ethanol extract of white ginseng), RDH (distilled water extract of red ginseng) and REH (70% ethanol extract of red ginseng). In this work, we have investigated the DPPH, hydroxyl radical, Fe2+-chelating activity, intracellular ROS scavenging capacity and lipid peroxidation of different ginsengs. All these extracts showed a dose dependent free-radical scavenging capacity and a ROS generation as well as lipid peroxidation was significantly reduced by treatment with bioactive extracts of white ginsengs (WDH) than red ginsengs. Additionally, white ginseng extracts (WDH) has dramatically increased intracellular antioxidant enzyme activities like superoxide dismutase and catalase in H2O2-treated HepG2 cells. All these results explain that administration of white ginseng is useful as herbal medicine than red ginseng for chemoprevention of liver damage.
