A re-pull-through operation for Hirschsprung's disease is performed when the primary operation has failed because of the remnant or acquired aganglionosis, anastomotic stricture and/or fistula. The purpose of this study is to review our experience of the re-pull-through procedure for Hirschsprung's disease. From May 1978 to July 2003, 26 patients who underwent re-pull-through operations at the Department of Pediatric Surgery, Seoul National University Children's Hospital, were studied retrospectively by means of chart review as well as telephone interview. The mean age at primary operation and re-operation were llmonths (2 months - 10 years) and 43 months (1 year - 23 years 3 months), respectively. Initial operation for Hirschsprung's disease was Duhamel's procedure in 17, Swenson's in 6 and Soave's 3. Causes of failure of primary operation were remains of secondary aganglionic segment (n=23), vascular arcade injury (n= 1), rectoperineal fistula (n=2, due to mesenteric torsion and poor blood supply), Mean interval between the primary operation and the re-operation was 34 months (6 months-22 years). Reoperation methods were Soave's in 12, Duhamel's in 8, APSP (abdomino-posterosagittal pull-through procedure) in 5, and Swenson's in 1 case. In 2 cases of repeated rectoperineal fistula or rectourethral fistula, re-APSP were performed 3 times, respectively. A total of 29 re-pull-through operations were performed. Postoperative complications were wound infection (n=1), adhesive ileus (n=1), rectoperineal fistula (n=3), rectourethral fistula (n=2), and death due to pulmonary embolism (n=1). Mean follow up period of reoperation was 78 months (1 month-23years). In current state, 2 patients have an ileostomy because of repeated rectoperineal fistula and rectourethral fistula. Of the remaining 23 patients, 21(91 %) are totally continent with or without minimal soiling. Reoperation for Hirschsprung's disease was effective and safe for the patients complicated to the initial pull-through operation.

■ Objectives The berries of Schisandra chinensis (Schisandra Fructus) are given the name Omiza in Koreane(五味子), and have been used asremedies for many ailments: to resist infections, increase skin health, and combat insomnia, coughing, and thirst. This study was designed to investigate the effects of Schisandra Fructus hexane fraction (SFH) on serum lipid levels in Hyperlipidemic mice. ■ Methods In this experiment, effects on total cholesterol, HDL-cholesterol, triglyceride, AST, ALT, fasting blood glucose in serum were measured. And in addition, histopathological and gene expression changes in liver tissue was also observed. ■ Results SFH did not affects weight gain, serum AST and ALT in hyperlipidemic mice. Oral administration of SFH lowered levels of total cholesterol and triglyceride, which were elevated by induction of hyperlipidemia. Finally, administration of SFH lowered fasting blood glucose significantly. And SFH also ameliorates anti-oxidative stress systems in internal organs which play key role in disease prevention. ■ Conclusion Results in our study suggest that SFH can prevent obese through regulation of dyslipidemia and hyperglycaemia.

With the aim of developing region specialized crops, this study was conducted to clarify effects of variant and cultivation region on antioxidative activities in various black soybean (Glycine max L.) seed tissues. Three black soybean varieties (SCEL-1, Wonheug, and Cheongja 3) were each cultivated in 4 different regions (Jeonju, Pyeongchang, Paju, and Cheonan). Harvested seeds were used to assess DPPH and ABTS radical scavenging activity, and total polyphenol, flavonoid and anthocyanin content. SCEL-1 soybean hull contained higher DPPH and ABTS radical scavenging activity (61% and 85% respectively) compared to Wonheug (40% and 50% respectively). SCEL-1 cultivated in Pyeongchang displayed the highest total polyphenol and flavonoid content (1,189 mg GAE/100g sample and 951 mg CTE/ 100g sample, respectively). Total anthocyanin content was ranked in the following order: SCEL-1>Wonheug>Cheongja 3. All black soybeans showed much higher antioxidant activity in the soybean hull than in the dehulled soybean. The antioxidant activity of black soybeans cultivated at high latitudes was high. These results suggest that the best black soybean variant for high beneficial biological activities is the SCEL-1 variant. For a complete understanding of the potential of black soybean as functional foods, we plan to further analyze their antioxidant activities in future studies.

Objectives : Gokgisaeng (Korean mistletoe) is used for the treatment of inflammatory and cancer diseases in traditional Korean medicine and its major component lectins have been reported to induce nitric oxide (NO) in RAW 264.7 macrophages, and also induce apoptosis of various types of cancer cells, although its modulatory effects on cancer cell migration and macrophage activation is poorly understood. The aim of this study is to clarify molecular mechanisms of action responsible for the anti-inflammatory and antitumor migration potentials of Korean mistletoe extract (KME). Methods : We investigated the anti-inflammatory activity of KME on NO production and inducible nitric oxide synthase (iNOS) expression by lipopolysaccharide (LPS) in both RAW 264.7 macrophages and rat C6 glioma cells, and also evaluated inhibitory efficacy on glioma cell growth and migration. For assessment, XTT assay, nitrite assay, RT-PCR, scratch-wound and Boyden chamber assay, and western blot analysis were performed. Results : Previously reported, unlike the efficacy of Gokgisaeng lectin, KME inhibited NO production and iNOS expression, and suppressed pro-inflammatory mediators including IL-$1{\beta}$, IL-6, COX-2, iNOS in LPS-stimulated RAW 264.7 cells. Furthermore, KME suppressed tumor cell growth and migration, and it also inhibited LPS-induced NO release and iNOS activation by down-regulating expression of protein kinase C (PKC) and phosphorylation of ERK in C6 glioma cells. Conclusions : Our research findings provide evidence that KME can play a significant role in blocking pro-inflammatory reaction and malignant progression of tumors through the suppression of NO/iNOS by down-regulating of inflammatory signaling pathways, PKC/ERK.
