Behcet's disease (BD) is a multisystem inflammatory disorder dominated clinically by recurrent oral and genital ulceration, uveitis and erythema nodosum. BD is very rare in children, especially those less than 10 years of age, who account for only an estimated 5% of all cases. Gastrointestinal ulcers, in patients with Behcet's disease with intestinal involvement are rare and have been reported in only 1-2% of all cases. The intestinal ulcers of Behcet's disease are usually multiple and scattered and tend to cause perforations associated with significant morbidity. Patients with BD and abdominal symptoms must be evaluated thoroughly for potential perforation of the gastrointestinal tract. Here we report the case of a 4 year 9 month old child with multiple perforations of the gastrointestinal tract associated with BD.

1. Objectives We introduced a case of postoperation stomach cancer patient with metastasis to peritoneum and colon who suffered from repetitive diarrhea and abdominal pain. 2. Methods Stomach cancet is the most common cancer in Korea. Eventhough the 5-year survival rate of stomach cancer is increasing recently, metastasized stomach cancer does not show good prognosis, especially when the surgical operation is not applicable. After partial resection of stomach, most of patients experienced gastrointestinal disorders like dyspepsia, reduced meal size, abdominal discomfort, loose stool, and constipation. 3. Results and Conclusions Taeumjowi-tang, a Sasang Constitutional Medicine, improved the diarrhea and abdominal pain.

Purpose: This study was performed to identify effects of pneumoperitoneum on hemodynamic changes of hypertensive patients undergoing laparoscopic colectomy under general anesthesia. Methods: Data collection was done from January 2 to June 10, 2008. Seventy-six patients, including 38 hypertensive patients, who had taken antihypertensive drugs more than 1 month and 38 normotensive patients undergoing laparoscopic colectomy were enrolled in this study. The hemodynamic parameters were heart rate (HR), mean arterial pressure (MAP) and cardiac output (CO) which were measured 7 times from before induction of anesthesia to 5 min after deflation of the pneumoperitoneum. Collected data were analyzed using Repeated Measures ANOVA and Bonferroni comparison method. Results: HR in the hypertensive group was significantly decreased at deflation of the pneumoperitoneum and 5 min after deflation of the pneumoperitoneum (p=.012). MAP in the hypertensive group was not different from the normotensive group (p=.756). CO in hypertensive group was significantly lower than normotensive group (p<.001) from immediately after pneumoperitoneum to 5 min after deflation of the pneumoperitoneum. Conclusion: The results indicate that pneumoperitoneum during laparoscopic surgery does not lead to clinically negative hemodynamic changes in heart rate, mean arterial pressure or cardiac output of hypertensive patients, who have taken antihypertensive drugs for more than 1 month.

The modulating effect of feeding sea mustard (Undarina pinnatifida), a fiber-rich seaweed, during initiation and post-initiation phases of colon carcinogenesis was investigated in Sprague Dawley rats. Four groups of animals were exposed to the two weekly injections of a chemical carcinogen, azoxymethane (AOM). Animals were placed on diet containing 15% sea mustard during initiation. post-initiation or initiation+post-initiation phase of carcinogenesis for 10 weeks, and colonic aberrant crypt formation and cell proliferation were compared to those of rats fed semi-synthetic control diet. Results showed that sea mustard feeding significantly reduced the numbers of both aberrant crypts and aberrant crypt foci. Also, labeling indices and proliferation zones were significantly reduced in the colon of the rats fed sea mustard diets. These results indicate that the diet containing sea mustard may decrease the risk of colon cancer development, and a part of such effect may be mediated through both the blocking of initiation and the suppression of cell proliferation in the colonic crypts, although precise mechanisms should be further examined.

An occurrence of hemangioma in the mediastinum is a very rare, accounting for less than 0.5% of mediastinal tumors. Capillary hemangiomas and cavernous hemangiomas consists of over 90% of mediastinal hemangiomas. However, venous hemangioma has never been reported in South Korea and has also very rarely been reported worldwide. We found mediastinal solid mass, as an incidental finding during a follow-up chest CT scan of a 44-year-old female patient who had undergone colon cancer surgery. We performed a mediastinoscopic biopsy. We did a thoracotomy to remove this mass because hemorrhage and found a totally resected venous hemangioma.

Epidural emphysema and pneumoscrotum with subcutaneous emphysema are rare in a child past the neonatal period. Their most common causes are bronchial asthma and respiratory infection. Here, we report an 18-month-old boy who was presented with severe air leak, consisting of epidural emphysema, pneumoscrotum, subcutaneous emphysema, and pneumomediastinum, complicated by a bronchial foreign body. The air leak was resolved dramatically after removing the foreign body.

We cloned the 5~kb Xlwl fragment containing gene responsible for degrad"tion of phenanthrene using pBLUES~ CRIPT SK( +) vector and E. coli XLI-Blue strain from the genomic library of Pseudomonas sp. 0177 and this recombinant plasmid was named pUPX5. The strain containing pUPX5 could produce a yellow meta-cleavage product using 2.3-dihydroxybiphenyl as a substrate. This strain have a higher activity toward 2,3-dihydroxybiphenyl than catechol. We sub cloned and localized the gene encoding 2.3-dihydroxybiphenyl-1.2-dioxygenase. which is designated as phn$\Omega$.

Ventilation performance in the storage hall of Janggyeongpan Jeon has maintained for more than 600 years. Janggyeongpan Jeon in Haein temple has window structure of bi-level ventilating opening which consists of upper and lower window. Also, different size and shape of windows are adopted for various locations of the hall. In the present study, to analyze effect of shape of windows on ventilation performance in the storage hall, various design alternatives were considered. Numerical analysis of ventilation in the storage hall was investigated under the same simulation condition except for the shape of windows. Through the comparison of numerical results for various window designs, it was evaluated that the current windows shape gives best ventilation performance.

The incidence of postoperative ileus (POI) after colonic and abdominal surgery is high. On the other hand, the reported incidence after lower extremity reconstruction ranges from 0.3% to 4.0%. This paper reports an 81-year-old woman who expired due to POI at six days after primary total knee arthroplasty. The risk factors, diagnosis, preventive methods, and treatment of POI were also investigated through literature reviews.

Ulcerative colitis (UC) exhibits chronic intestinal inflammatory conditions with cycles of relapse and remission. The incidence is rapidly growing in Asian countries including South Korea possibly due to changes in lifestyles. Although the etiology of inflammatory bowel disease is inconclusive, gut microbiota composition is considered a critical factor involved in the pathogenesis of UC. The overgrowth of pathogenic bacteria evokes hyper-immune responses in gut epithelium causing tissue inflammation and damage. Also, failure to regulate gut epithelium integrity due to chronic inflammation and mucus depletion accelerates bacterial translocation aggravating immune dysregulation. Gut microbiota composition responds to the diet in a very rapid manner. Epidemiological studies have indicated that the risk of UC is associated with low plant foods/high animal foods consumption. Several bacterial strains consistently found depleted in UC patients use plant food-originated dietary fiber producing short chain fatty acids to maintain epithelial integrity. These bacteria also use mucus layer mucin to keep gut microbiota diversity. These studies partly explain the association between dietary modification of gut microbiota in UC development. Further human intervention trials are required to allow the use of specific bacterial strains in the management of UC.
