Here we described 8 patients treated with acupuncture and moxiburstion due to chronic postoperative pain as a comlication of gastrointestinal surgery. The patients were suffering from pain that continued for more than 6 months after laparotomy for gastric cancer (n=1), rectal cancer (n=2), cholangiocarcinoma (n=2), hepatocellular carcinoma (n=2) and ischemic colitis (n=1), respectively. Mean time elased from surgery were 31.25(${\pm}21.72$)months, pain grade on first visit by VAS(visual analogue scale, 0~10mm) was 3.75(${\pm}0.97$)point, and acupuncture and moxiburstion were performed 12.63(${\pm}5.74$)times during 5.5(${\pm}2.4$)weeks, on average. At the end of treatment, pain was decreased 2.75(${\pm}0.97$)point compared to first visit. Based on the that results, it is reasonable to assume that acupuncture and moxiburstion can be effective to persistent post-surgical pain after laparotomic gastrointestinal surgery, at least to some laparotomized patients.

We analyzed the functional fragrant components of three species of Cymbidium oriental orchids using gas chromatography-mass spectrometry (GC/MS). For the comparative analysis, C. goeringii 'Minchunran', 'Jugeumhwa', C. forrestii 'Chwigae', 'Songmae', 'Yongja', and C. faberi 'Choemae', 'Namyangmae', 'Hwaja' were investigated. Major fragrant components detected by GC/MS were selected on the basis of more than 3% value according to the analysis of peak area (%). We found that ${\alpha}$-bergamotene, which has a cytotoxic effect on breast cancer, cervical cancer, and glioblastoma, and nerolidol, which induces apoptosis of human hepatoma cells (HepG2), inhibits the growth of Streptococcus mutans and babesiosis, and has antibacterial properties, are common substances produced by C. goeringii L. Nerolidol and ${\beta}$-bisabolene, which is cytotoxic and suppresses the growth of malignant melanoma cells (B16-F10), HepG2, and leukemia cells (HL-60, K562), are major substances in C. forrestii R. Furthermore, ${\alpha}$-pinene, which inhibits the growth of gliobastoma cells (SF-767) and inhibits the anti-inflammatory action of hepatoma cells (BEL-7402); 1,8-cineole, which is a potential therapeutic agent for the treatment of gastric ulcers; and 1,3,7-octatriene, which functions as a pheromone, are the most common substances in C. faveri R. Thus, substances identified as major fragrant components in oriental orchid species have multiple beneficial applications in human health. This research forms the basis for further studies of the roles of major fragrant components in oriental orchids.

Background: The efficacy of standard treatment of Helicobacter pylori (H. pylori) is declining because of antibiotic resistance. Clarithromycin resistance is also increasing in many Asian countries. The aim of this study was to determine the antibiotic susceptibility patterns of H. pylori infection and clinical association in Laos. Materials and Methods: A total of 329 Lao dyspeptic patients who underwent gastroscopy at Mahosot Hospital, Vientiane, Laos during December 2010-March 2012 were enrolled in this study. During gastroscopy, 4 biopsies were collected (2 each from the antrum and body) for CLO-test and histopathology. Only the positive CLO-test gastric tissues was stored at $-80^{\circ}C$ in a freezer until DNA was extracted and a GenoType$^{(R)}$HelicoDR test was conducted for detecting mutations in the rrl gene encoding 23S rRNA (clarithromycin resistance) and mutations in gyrA gene (fluoroquinolone resistance). Results: Of the total, 119 Lao patients (36.2%) were infected with H. pylori including 59 males (49.6%) and 60 females (50.4%) with a mean age of 46 years. Clarithromycin and fluoroquinolone resistance of H. pylori infection was demonstrated in 15 (12.6%) and 16 strains (13.4%) respectively. In clarithromycin resistance, the number of patients who had education above primary school and $BMI{\geq}25kg/m^2$ were significantly higher than those who had education below primary school and BMI<$25kg/m^2$ (23.1% vs 7.5%, P-value= 0.036 and 20.5% vs 8%, P-value= 0.048, respectively). In fluoroquinolone resistance, the number of lowland Lao was significantly higher than those of non-lowland (highland and midland) Lao ethnic groups (16.7% vs 0%, P-value= 0.039). Conclusions: H. pylori infections remain common in Laos. Clarithromycin and fluoroquinolone resistance with H. pylori infection are growing problems. Education above primary school and $BMI{\geq}25kg/m^2$ might be predictors for clarithromycin resistance and lowland Lao ethnicity might be predictors for fluoroquinolone resistance with H. pylori infection in Laos.

Phellinus linteus (Sang Hwang mushroom; P. linteusis) has been widely used for a traditional medicine in Japan, Korea and China. In traditional oriental applications, P. linteus and their extracts have been exclusively used to treat various diseases like insomnia, neurasthenia, gastric ulcers, arthritis, nephritis, stress, asthma, bronchitis, neuromuscular disorders, hypertension and also as an immune system stimulator in cancer therapy. In a number of articles, it is indicated how tremendous their therapeutic values are. According to these studies, P. linteus and their extracts show immunomodulatory activities like enhancing immune system function including anti-tumor activity and inhibiting the growth of existing tumors. P. linteus and their extracts have been being studied for use as immunotherapy agents and biological response modifiers (BRMs) for the possible treatment of cancer without side effects. Recently, the cultured mycelium product of P. linteus has been developed and approved as a medicine in Korea. This review shows not only the current status of methods of developmental technology like artificial culture and various biological applications of P. linteus but also recent market trends of functional foods made from P. linteus.

Purpose: To assess the influence of cyclooxygenase-2 (COX-2) expression on the survival of patients with a combination of rectal cancer and lymph node metastasis. Materials and Methods: The study included rectal cancer patients treated by radical surgery and postoperative radiotherapy at the Dong-A university hospital from 1998 to 2004. A retrospective analysis was performed on a subset of patients that also had lymph node metastasis. After excluding eight of 86 patients, due to missing tissue samples in three, malignant melanoma in one, treatment of gastric cancer around one year before diagnosis in one, detection of lung cancer after one year of diagnosis in one, liver metastasis in one, and refusal of radiotherapy after 720 cGy in one, 78 patients were analyzed. The immunohistochemistry for COX-2 was conducted with an autostainer (BenchMark; Ventana, Tucson, AZ, USA). An image analyzer (TissueMine; Bioimagene, Cupertino, CA, USA) was used for analysis after scanning (ScanScope; Aperio, Vista, CA, USA). A survival analysis was performed using the Kaplan Meier method and significance was evaluated using the log rank test. Results: COX-2 was stained positively in 62 patients (79.5%) and negatively in 16 (20.5%). A total of 6 (7.7%), 15 (19.2%), and 41 (52.6%) patients were of grades 1, 2, and 3, respectively for COX-2 expression. No correlation was found between being positive of COX-2 patient characteristics, which include age (<60-year old vs. $\geq$60), sex, operation methods (abdominoperineal resection vs. lower anterior resection), degrees of differentiation, tumor size (<5 cm vs. $\geq$5 cm), T stages, N stages, and stages (IIIa, IIIb, IIIc). The 5-year overall and 5-year disease free survival rates for the entire patient population were 57.0% and 51.6%, respectively. The 5-year overall survival rates for the COX-2 positive and negative patients were 53.0% and 72.9%, respectively (p=0.146). Further, the 5-year disease free survival rates for the COX-2 positive and negative patients were 46.3% and 72.7%, respectively (p=0.118). The 5-year overall survival rates were significantly different (p<0.05) for the degree of differentiation, N stage, and stage, whereas the 5-year disease free survival rates were significant for N stage and stage. Conclusion: Being positive for and the degree of COX-2 expression did not have a significant influence on the survival of rectal cancer patients with lymph node metastasis. However, N stage and stage did significantly influence the rateof survival. Further analysis of a greater sample size is necessary for the verification of the effect of COX-2 expression on the survival of rectal cancer patients with lymph node involvement.

Halitosis is a generally accepted marker of diseases in the oral cavity and of systemic and gastrointestinal disorders. Based on these authors' previous findings (that (1) there is a close association between H. pylori infection and halitosis; (2) Korea red ginseng may suppress the colonization of H. pylori, fight H. pylori-induced cytotoxicity, and impose significant anti-inflammatory actions in patients with chronic gastritis; and (3) H. pylori infection is linked with the generation of significant levels of volatile sulfur compounds (VSCs), and the levels of VSCs correlate significantly with H. pylori-associated mucosal damages), in the current study, the authors documented the molecular mechanisms of Korea red ginseng's efficacy in ameliorating halitosis. When the RAW 264.7 cells were treated with the $H_2S$ releasing compound NaHS, the mRNA expression of cystathionine ${\gamma}$-lyase (CSE), IL-6, COX-2, and iNOS were more significantly induced compared with the vehicle-treated group. The cytoskeletal components of ezrin's and moesin's mRNA expressions were elevated by NaHS treatment accompanied by the activation of MAPK, p38, and ERK. Korea red ginseng pretreatment reduced both the NaHS-induced CSE expression and the proinflammatory genes (e.g., IL-6, COX-2, and iNOS) in a concentration-dependent manner. The ERM expression and the phosphorylation of p38 were also significantly reduced by Korea-red-ginseng pretreatment. Overall, Korea red ginseng pretreatment imposed significant anti-inflammatory effects through the downregulation of the NaHS-triggered proinflammatory gene expression, CSE, and ERM mRNA expression. Korea red ginseng could thus be said to be a key remedy of halitosis and to be effective in relieving gastric inflammation.

Three sesquiterpene ortho-naphthoquinones were isolated from the methanolic extract of root bark of Ulmus davidiana Planch whose stem and root bark have been used as an oriental medicine for the treatment of edema, mastitis, gastric cancer and inflammation. The structures of these compounds were established on the basis of spectral data obtained from UV-vis, IR, HR-EIMS and NMR spectrometry, including the pulse field gradient (PFG)-HMQC and HMBC techniques. Their structures were determined as 2,3-dihydro-3,6,9-trimethylnaphtho(1,8-b,c)pyran-7,8-dione, 3,6,9-trimethylnaphtho(1,8-b,c)pyran-7,8-dione and 2,3-dihydro-4-hedroxy-3,6, 9-trimethylnaphtho(1,8-b,c)pyran-7,8-dione, which were identified as mansonones E. F and H, respectively. These compounds have originally been isolated from Mansonia altissima Chev, but have never been isolated from Ulmus davidiana Planch. Especially, mansonone H was isolated for the first time from Ulmaceae. The mismatched carbon chemical shifts of mansonones E and F in the reported literature were corrected by the aid of the PFG-HMBC spectral data.

Purpose: This study was done to clarify effects of bispectral index monitoring sedative administration, compared to MOAA/S (Modified Observer's Assessment of Alertness and Sedation), on conscious sedation, physiological stability and recovery time for patients undergoing endoscopic submucosal dissection. Methods: Participants In this study were patients who underwent endoscopic submucosal dissection because of early gastric cancer. Participants were assigned randomly to an experimental group receiving sedatives based on bispectral index monitoring or to a control group with the MOAA/S instrument. Movements, belching, memory, pain, discomfort, physiological stability (MBP, PR, $SpO_2$), and recovery time were measured during the treatment and recovery. Data were analyzed using Spearman partial correlation coefficient analysis, Mixed model and Wilcoxon rank sum test to determine differences in the parameters. Results: There were no statistically significant differences between the two groups for conscious sedation(movement, belching, memory, pain, or discomfort), physiological stability and recovery time. Conclusion: The results of this study indicate that no differences were found between the two types of monitoring. Thus, use of a bispectral index monitor in clinical practice enabling medical staff to readily assess the conscious sedation of for these patients is expected to be increasingly used as an objective assessment tool for conscious sedation for patient safety.

A 56 year-old man complaining of dry cough, dyspnea, chest pain, fever, and chills was admitted to the emergency room. The patient had a history of esophagectomy and esophagogastrostomy and subsequent radiotherapy because of an esophageal cancer. After the emergency echocardiography revealed a small amount of pericardial effusion and pneumopericardium. Upper GI contrast study showed a fistulous tract between the stomach and the pericardium, and an emergency operation was done under the diagnosis of gastropericardial fistula. The patient expired postoperative seven days later. Gastropericardial fistula caused by a peptic ulcer perforation after the esophagectomy and esophagogastrostomy operation is a very rare complication and brings forth a disastrous result. Early detection using the chest radiography, electrocardiogram, upper Gl study, echocardiography and a review of physical examination, and an immediate treatment are therefore mandatory.

This study was designed to investigate the effect of fucoidan on the activation of macrophage and on induction of apoptosis in AGS cell. To measure the activity of macrophages, NO and TNF-${\alpha}$ assays were performed in Raw 264.7 cell. Treatment with fucoidan significantly increased production of NO and TNF-${\alpha}$, indicating activation of macrophages. The result of MTT assay shows that cell viability was significantly decreased in a dose and time-dependent manner. Fucoidan increased to enhance mitochondrial membrane permeability, as well as the cytochrome c release from the mitochondria. Fucoidan decreased Bcl-2 and XIAP expression, whereas the expression of Bax was increased in a time-dependent manner compared to the control. In addition, the active forms of caspase-9 were increased, and the inactivation of Akt was decreased in a time-dependent manner. Caspase inhibitor, z-VAD-FMK, canceled the apoptosis of fucoidan, expression of Bax and caspase-9 were decrease. These results indicate that fucoidan induces activation of macrophage and apoptosis through activation of caspase on AGS cell.
