BACKGROUND: Korean mistletoe (Viscum album) extract has been found to posses immunostimulatory activity. In this study, Korean mistletoe extract, M11C (non-lectin components), was used to know whether this extract might activate mouse peritoneal macrophages to produce interleukin 1 beta (IL-1 beta). METHODS: Hemagglutination assay was carried out to examine whether M11C contained a lectin or not . To know the effect of M11C on the production of IL-1 beta, the macrophages were treated by the M11C, and then collected the supernatant (M11C stimulated macrophages-conditioned media; MMCM). MMCM was analyzed for the IL-1 beta quantification and mRNA expression by means of ELISA and RT-PCR, respectively. RESULTS: Maximum effective dose and time of M11C on IL-1 beta production from macrophages were 20 micro gram/ml and 8 hours, respectively . This ELISA data was reconfirmed by immunoblotting assay . indicating that M11C is a good candidate for an immunomodulator. The dose and time dependent effect s of M11C on the expression of IL-1 beta mRNA from macrophages was also shown in expression of mRNA detected by RT-PCR. Treatment dose and time for the maximum expression of IL-1 beta mRNA were 20 micro gram/ml and 4 hours, respectively . Maximum gene expression of IL-1 beta was much earlier than maximum production of it. CONCLUSION: As results, Korean mistletoe extract, M11C, may be used for an immunomodulator. This will be able to make up for and solve the problems caused by existent immunoagent with many adverse effects through many other studies in future including one molecule extraction.

A lymphangioma is comparatively rare in the elimentary tract, and is a benign tumor of the lymphatic system. A duodenal lymphangioma is especially rare, and has an obscure etiology. Clinically, and in the laboratory the are non-specific, and are incidentally found by endoscopy, and their treatment is total excision. Recently, the authors experienced a 45 year-old woman, who had a duodenal lymphangioma, but with no symptom. An endoscopic examination revealed a single, about 2 cm, polypoid lesion below the ampulla. The lesion was successfully excised after a duodenotomy.

BACKGROUND: The stones in the biliary tree situated proximal to the origin of the common hepatic duct are considered intrahepatic duct stone. This conditon causes the serious problems including cholangitis, obstructive jaundice and liver abscess. AIM AND METHOD: This study is a clinical review for the results of surgical treatment in 178 cases of patients with intrahepatic stones in the Department of Surgery, Gyeongsang National University Hospital from January 1991 to December 1997. RESULTS: Sex ratio of male to female was 1 : 2.1 and most prevalent age group was 6th decade. Common symptom and sign was RUQ pain(83.2%) and tenderness(64.7%). Common laboratory finding were elevated alkaline phosphatase(56.6%), elevated serum GOT(47.4%), leukocytosis (44.5%) and hyperbilirubinemia(36.4%). C. Sinensis was identified in 22 cases(12.4%) of operation cases. Intrahepatic stones were located in the left hepatic duct in 87 cases(48.9%), the right duct in 27 cases(15.2%) and both intrahepatic duct in 64 cases (35.9%). Partial hepatectomy was performed in 94 cases(52.8%), non-hepatectomy was performed in 84 cases(47.2%). The remained stone was noted in 57 cases(32%) of operation cases. Among them, 39 cases(68%) were non-hepatic group, 18 cases(32%) were hepatic group. Postoperative complication rate in hepatic resection group(29.8%) was higher than that in non-resection group(15.5%). Most common complication was wound infection and operative mortality was 2.2%. The follow-up study showed that 146 cases(82%) were graded as good, 7 cases(3.9%) as fair and 25 cases(14%) as poor result and relative incidence of good result in hepatic resection group(88.3%) was higher than that in non-hepatic group(75%). CONCLUSIONS: We conclude that hepatic resection rather than biliary bypass procedure alone as an initial treatment for hepatolithiasis is satisfactory treatment.

BACKGROUND: Resolution of postoperative ileus has traditionally been the moment at which bowel function returns. The re-start of postoperative oral feeding usually occurs after that. Recently, many reports have been published on early postoperative feeding in patients operated on laparoscopically and even in patients receiving a laparotomy. The aim of this study was to scrutinize the validity of early postoperative feeding. METHODS: Fiftyfour colorectal cancer patients who had undergone radical resective surgery for cure were included in this study and were divided into two group. Group 1 included 32 patients who were fed in a traditional manner. Group 2 consisted of 22 patients who received a regular diet on the first postoperative day. The mean age was 62, the male-to-female ratio was 1.2:1. Thirteen tumor were located on the right side colon, 4 on the left side colon, 10 on the rectosigmoid, 27 on the rectum. Operative methods were 13 right hemicolectomies, 4 left hemicolectomies, 19 low anterior resections, and 18 abdominoperineal resections. The possible problems associated with early oral feeding were well understood by the patients and consents were obtained. Immediately after the operation, the nasogastric tube was removed in the operation room, and The time of complete recovery from anesthesia was 3 to 5 hours later. At that time, liquid drink was given; then, liquid food or blended food was allowed. RESULT: Early oral intake was tolerable in 14 patients out of 21 (67%); in 8 patients a nasogastric tube was reinserted due to severe nausea, vomiting, and/or abdominal distension. All those minor problems were resolved after reinsertion of the nasogastric tube and returning to the traditional method. In one patient, who had a received a low anterior resection, a serious complication, anastomatic leakage, developed. Early oral intake was not thought to be the exact cause of the leakage, but it made the problem more complicated. A huge amount of feces soiled the peritoneal cavity and the already dissected retroperitoneum. CONCLUSIONS: The tolerability of early postoperative oral intake was 67%. In the remainder of patients, all the minor problems except one, were relieved by simply returning to the traditional method. However, early postoperative oral intake should be used with caution for patients who experience difficulty with anastomosis or have an intraoperative technical breakdown and in whom the possibility of leakage exists.

PURPOSE: Acute appendicitis is one of the most common causes of abdominal emergency. Children, under age of 5 years, are unable to give an accurate history, but other nonspecific abdominal pain is more common at this age. Because diagnosis is often delayed and progression of appendicitis is faster, incidence and perforation rate is higher than those of adults. Abdominal US and CT are helpful in diagnosis of acute appendicitis. METHODS: Between July, 1997 and April, 2004, 39 patients below 5-year-old were participated, but 2 (Negative) patients were excluded. This study was done retrospectively based on medical charts. For statistical analysis, Chi-squre test was used. RESULTS: All patients undergone emergency operations, in which male to female ratio was 1.79: 1, with its mean age of 4.05. 19 patients (49%) were perforated and fever developed more frequently in perforating group, but leukocytosis was not significant. Delayed preoperative duration was associated with perforation rate significantly. All complications were occurred in perforating group. CONCLUSION: To decrease perforation rate and complications, early diagnosis and management are necessary to avoid delaying preoperative time.

An epigastric hernia is a protrusion of the extra-peritoneal fat to the linea alba, between the xiphoid process and the umbilicus. About 3~5% of people develop epigastric hernias. The authors have experienced a case of a 79 year-old woman who had an asymptomatic epigastric hernia, where an abdomen CT is helpful in its diagnosis. The size of the defect was large, and a hernia sac existed. The case of an epigastric hernia, which was treated by a primary repair, is reported, with a brief review of the literature.

PURPOSE: Due to its size and locatin, the liver is frequently injured in abdominal trauma. Recently, nonoperative management for liver injuries has been extended due to the development CT imaging, intensive care units, and their equipment and techniques. Herein, patients with traumatic liver injury were analyzed to evaluate its treatment and prognostic factors. METHODS: From 2001, January to 2003, July, 65 patients at our facility were confirmed to have traumatic liver injury. The operative or nonoperative managements were decided on the basis of the systolic blood pressure if no peritoneal irritation sign was noted. If the systolic blood pressure was stable, or recovered to within the normal range following hydration and transfusion at the emergency room, patients were managed nonoperatively. Hemodynamically unstable patients were managed operatively. The data were analysed using the SPSS program (Chi-squared tests and logistic regression analyses). RESULTS: 48 patients were treated nonoperatively, with 3 mortalities. The overall mortality rate was 15.8%, but only 6.4% in the nonoperative management group, compared to 67% in operative management group. In a Multivariate analysis the systolic blood pressure was found to be a reliable factor in traumatic liver injury and the mentality and ISS (injury severity score) reliable in finding complications in the nonoperative management group. The mentality was found statistically reliable for determining mortality in the operative management group, with the exception for the systolic blood pressure. CONCLUSION: The systolic blood pressure was an important indicator when considering the treatment plan in traumatic liver injury. An extensive study will be required that incorporates both nonoperative and operative management groups.

Axonal swellings or retraction balls are the major histologic hallmark of diffuse axonal injury in craniocerebral trauma. However, traditional histologic methods have proven of limited use in identifying reactive axonal change early in the posttraumatic course. In the present study, we try to compare conventional histologic and immunohistochemical methods, and transmission electron microscopy for demonstrating axonal swellings in 18 cases of head trauma. Brain regions such as corpus callosum, cerebral cortex, and brain stem were examined with immunohistochemical markers for beta-Amyloid precursor protein (beta-APP), neurofilament, ubiquitin, and CD68. The result was as follows: In 2 out of 18 cases, eosiniophilic spheroid axon balls were demonstrated with hematoxylineosin stain. Ultrastructurally, the axon balls exhibited misalignment, clumping or loss of neurofilaments, and accumulation of organelles. The organelles consisted of mitochondria, dense membranous bodies, and SER. The overlying thin myelin sheath was distended. In 6 cases with no axonal swellings at the histologic section, electron microscopic examination revealed axonopathy as evidenced by disintegration of neurofilaments and aggregated organelles. Immunostaining with an antibody to beta-APP disclosed varying positive reaction in axonal swellings and axon balls, suggestive for injured axons. However, the axons which did not appear obviously swollen at short survival times disclosed beta-APP negativity. Our findings suggest that transmission electron microscopy was very useful to identify the early axonal events in the posttraumatic course, while the immunostain was of limited value. The pathogenesis of axonal swellings in injured axons was discussed.
