Purpose: We aimed to investigate the correlations between expressions of angiogenic cytokines VEGF-A, C, D of primary colorectal cancer and liver metastasis. Methods: We examined paraffin-embedded primary colorectal cancer tissue from 45 patients who had liver resection due to colorectal liver metastasis (metastasis group) and 37 patients who had surgical resection due to colorectal cancer only (control group). In the control group, local recurrence and distant metastasis had not occurred. Immunohistochemical staining for VEGF-A, C and D was performed. We analysed the correlations between expression of VEGF-A, C and D in primary colorectal cancer tissues and clinicopathologic parameters. Results: VEGF-A expressions of primary colorectal carcinoma were not different between the two groups. VEGF-C was more frequently expressed in the metastasis group (P=0.008) but VEGF-D was more expressed in the control group (P=0.003). Patients with VEGF-C negative and VEGF-D positive expression were predominant in the control group (P=0.020). Tumor location, T stage, lymph node metastasis and tumor differentiation were not related with the expressions of VEGF-A, C, D but only preoperative CEA was positively correlated with VEGF-A and C expression. Conclusion: Expressions of VEGF-C in primary tumor were more frequent in metastatic colorectal cancer and expressions of VEGF-D were more frequent in nonmetastatic colorectal cancer. More large-scale prospective studies for VEGF-C and D expression in colorectal cancer are necessary.

Purpose : to assess the efficacy and toxicity of the preoperative radiotherapy with or without chemotherapy in locally advanced rectal cancer. Methods : Forty three patients (clinically diagnosed stages above or equal to Astler-Coller stage B2 without distant metastasis) were assigned to preoperative radiotherapy alone arm (n=16) or combined preoperative radiotherapy and chemotherapy arm (n=27). Preoperative radiotherapy of 4500 cGy to whole pelvis +/- 540 cGy boost to primary site and concurrent chemotherapy of 2 cycles of 5-FU (500mg/m²) and leucovorin (20mg/m²) were used. fifteen patients of preoperative radiotherapy alone arm and 19 of combined arm received surgical resection after preoperative treatment. Results : During the preoperative treatment, no significant complication was developed in both groups. Pathologic results were as follows; complete remission 1, B1 1, B2 6, C1 2, C2 5 in preoperative radiotherapy alone arm and complete remission 2, B1 8, B2 4, C2 3, D 2 in combined arm. Postoperative complications were delayed perineal wound healing in three patients, intestinal obstruction in three patients (one managed by conservative medical treatment, two by surgical treatment). conclusion : The combined preoperative radiotherapy and chemotherapy arm was more affective in pathological response and lymph node negativity rate than the preoperative radiotherapy alone arm. Both the preoperative radiotherapy alone arm and the combined arm were generally well tolerated and did not result in an increased postoperative morbidity.

The microtuber was efficiently formed on SH medium containing 9% sucrose from the in vitro propagated shoot of potato (Solanum tuberosum cv. Sumi). In order to investigate gene expression depending on the developmental stage of microtuber, we examined the changes of peroxidase and esterase activities, and their isozyme patterns as well. Peroxidase and esterase activities were the highest at the 7 day-culture of the microtuber and subsequently decreased on the stage of microtuberization, whereas esterase activity increased at the stage of 60 day-culture. However, their activities in the ordinary tuber were higher than those of 60 day-cultured microtuber. In addition, in the peroxidase isozyme pattern two new bands of pI 7.05 and pI 4.65 were appeared at the 15- day and 60 day-cultures, respectively, as shown by isoelectric focusing. Various bands in the esterase isozyme pattern were shown at the 7 day-culture, and the band patterns were a large difference, comparing those of shoot and tuber. New bands in the esterase isozyme pattern also appeared at the 15 day- (pI 4.52) and 60 day-cultures (pI 4.48). These results suggest that the changes of peroxidase and esterase activities and isozyme patterns are an important factor in the differentiation and development of potato.

Objectives ; The objective of this study was to evaluate the prevalence of atrophic gastritis and intestinal metaplasia according to gender, age and Helicobacter pylori infection in a rural population in Korea. Methods: Between April 2003 and January 2007, 713 subjects (298 men and 415 women, age range: 18-85) among the 2,161 adults who participated in a population-based survey received gastrointestinal endoscopy. All the subjects provided informed consent. Multiple biopsy specimens were evaluated for the presence of atrophic gastritis and intestinal metaplasia. The presence of Helicobacter Pylori was determined using CLO and histology testing. Results ; The age-adjusted prevalence of atrophic gastritis was 42.7% for men and 38.1% for women and the prevalence of intestinal metaplasia was 42.5% for men and 32.7% for women. The prevalence of atrophic gastritis and intestinal metaplasia increased significantly with age for both men and women (p for trend<0.001). The age-adjusted prevalence of Helicobacter pylori was similar for men (59.0%) and women (56.7%). The subjects with Helicobacter pylori infection showed a significantly higher prevalence of intestinal metaplasia (44.3%) compared with that (26.8%) of the noninfected subjects (p<0.001). However, the prevalence of atrophic gastritis was not statistically different between the Helicobacter pylori-infected subjects and the noninfected individuals. Conclusions : Our findings suggest that the prevalence of atrophic gastritis and intestinal metaplasia is higher for a Korean rural population than that for a Western population; this may be related to the high incidence of gastric cancer in Koreans. Especially, the prevalence of intestinal metaplasia was high for the subjects with Helicobacter pylori infection. The multistep process of gastric carcinogenesis and the various factors contributing to each step of this process need to be determined by conducting future follow-up studies.

A morphologic study on the effect of butylated hydroxytoluene (BHT) on experimental hepatocarcinogenesis induced by 3'-methyl-4-dimethyl aminoazobenzene (3'-MeDAB) was investigated. A total of 110 Sprague-Dowley male rats weighting about 200 g each were used for the experiment, and divided into 4 groups; the 3'-MeDAB, BHT, 3'-MeDAB/BHT treated group, and the control group. Four to eight rats of each group were sacrified on the 4th, 8th, 14th and 16th experimental weeks, with continuous pelletized feeding containing 0.09% 3'-MeDAB and 0.5% BHT. The liver was examined by transmission and scanning electron microscopy. The results were as follows; Electron microscopically, the fine structure of the hepatocytes remained consistently abnormal up to 16 weeks after the 3'-MeDAB treatment. There was no significant difference in the groups observed earlier than in the ones observed later. Many subcellular changes were observed : nuclear change, decreased glycogen, mitochondrial abnormalities, disaggregated rough endoplasmic reticulum, marked proliferation of smooth endoplasmic reticulum, dilatation and distortion of bile canaliculi, increased lysosomes, apoptotic bodies, migration of bile ductule cell. In the BHT treated group, the ultrastructural changes of hepatocytes were not significant, except for the lipid droplets and proliferated smooth endoplasmic reticulum among hepatocytes depending on the experimental duration. The various subcellular changes of 3'-MeDAB/BHT treated groups were simillar to those of the 3'-MeDAB treated group, but the degree of changes in the 3'-MeDAB/ BHT treated group decreased compared with those of the 3'-MeDAB treated group. These results suggest that dietary butylated hydroxytoluene has a protective/inhibitory effect on the hepatocarcinogenesis induced by 3'-methyl-4-dimethyl -aminoazobenzene.

Most mucosa-associated lymphoid tissue (MALT) lymphomas are found in the gastrointestinal tract. The most common site is the stomach, whereas colon MALT lymphomas are rare. There are a few reports of simultaneously diagnosed stomach and colon MALT lymphomas. However, diagnosis of primary colonic MALT lymphoma after complete remission of gastric MALT lymphoma is extremely rare. Although the treatment protocol for gastric MALT lymphoma is well established, there is no consensus protocol for colonic MALT lymphoma owing to its rarity. Herein, we report a case of colonic MALT lymphoma incidentally diagnosed 6 months after completion of radiation therapy for gastric MALT lymphoma and treated via polypectomy, with no recurrence for 3 years.

Purpose: The aim of this study was to evaluate the shortterm outcome of a pylorus-preserving proximal gastrectomy by comparing it with a jejunal interposition after a total gastrectomy in proximal gastric adenocarcinoma. Materials and Methods: For 22 patients (12 men and 10 women) who underwent a pylorus-preserving proximal gastrectomy, several clinical parameters were obtained from the medical records retrospectively. In this study, the data were collected between September 1993 and December 1999 at Chungnam National University Hospital, and the results were compared with those of 25 patients (17 men and 8 women) who underwent an isoperistaltic simple jejunal interposition. Results: The average operative time in the pylorus-preserving proximal gastrectomy group (220 minutes) was shorter than that in the jejunal interposition group (243 minutes) (P<0.05). The hemoglobin and hematocrit levels were significantly higher in the pylorus-preserving proximal gastrectomy group at 2 years after the operation. The body weight ratio (postoperative body weight/preoparative body weight) in patients who had a pylorus-preserving proximal gastrectomy was significantly higher than that in patients with a jejunal interposition at 2 years after the operation. The jejunal interposition procedure had better outcomes in anastomotic site stricture, duration of hospital stay, and number of removed lymph nodes (P<0.05). Conclusions: We think that from the viewpoint of quality of life, a pylorus-preserving proximal gastrectomy, as well as a jejunal interposition, is a useful reconstruction method for early adenocarcinomas of the proximal stomach. However, stricture of the esophagogastrostomy site in the pyloruspreserving proximal gastrectomy is a common problem to be solved in the future.

Purpose: The aim of this study was to evaluate the shortterm outcome of a jejunal interposition, by comparing it with a conventional Roux-en-Y gastrojejunostomy, after a total gastrectomy. Materials and Methods: For 28 patients (20 men and 8 women) with a gastric adenocarcinoma, who underwent an isoperistaltic simple jejunal interposition, weight, hemoglobin, hematocrit, serum protein and albumin, and cholesterol levels were checked before the operation and at 1 year and 2 years after the surgery. Also, endoscopy was performed to confirm reflux esophagitis. In this study, the data were collected between January 1993 and July 1999 at Chungnam National University Hospital, and the results were compared with those of the Roux-en-Y procedure. Results: The body weights at 1 year and 2 years after the surgery had returned to $86.0\%$ and $87.6\%$ of the recent original body weight in the jejunal interposition (JI) group and to $90.8\%,\;87.0\%$, respectively in the Roux-en-Y (RY) group. The levels of hemoglobin (g/dl) were 13.3, 12.5, and 11.9 in the JI group, and 13.8, 12.6, and 12.1 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum protein (g/dl) levels were 7.1, 7.2, and 7.5 in the JI group and 7.1, 7.0, and 7.2 in the RY gropu at the time of the operation and at 1 year and 2 years after the surgery, respectively. The serum albumin (g/dl) levels were 4.2, 4.1, and 4.2 in the JI group and 4.2, 4.2, and 4.2 in the RY group at the time of the operation and at 1 year, and 2 years after the surgery, respectively. The total serum cholesterol (mg/dl) levels were 186.5, 174, and 164 in the JI group and 213.7, 171.1, and 141.0 in the RY group at the time of the operation and at 1 year and 2 years after the surgery, respectively. The endoscopic finding showed that reflux esophagitis occurred in $7.1\%$ of the patients in the JI group and in $3.5\%$ in the RY group. Conclusion: We think that from the view point of quality of life, a jejunal interposition, as well as a Roux-en-Y procedure, is a useful reconstruction methods for a total gastrectomy.

원발성 점액섬모 이송기능 장애 환자에서 발생한 뇌농양 - 증례보고 -

윤성훈,이형진,이진석,양지호,이일우,송규상,강준기,Yoon, Sung Hoon,Lee, Hyung Jin,Yi, Jin Seok,Yang, Ji Ho,Lee, Il Woo,Song, Kyu Sang,Kang, Joon Ki 대한신경외과학회 2001 Journal of Korean neurosurgical society Vol.30 No.12

The authors present a case of brain abscess in a patient with primary mucociliary transport failure. Primary mucociliary transport failure is unfamiliar term to neurosurgeon. It encompasses three hereditary disorders, that is, primary ciliary dyskinesia, cystic fibrosis and Young's syndrome. Clinical manifestations in these disorders appear to overlap each other, e.g., male infertility and chronic sinopulmonary infections. These are characterized by ciliary dysfunction or abnormality of mucus secretion therefore recurrent infection occurs in organs containing the mucociliary transport system. Major causes of non-traumatic brain abscess are sinusitis and pulmonary infection. So the possibility of brain abscess is much higher if mucociliary transport failure exists. Especially, young patients who have brain abscess coexisting with chronic sinopulmonary infection should be considered primary mucociliary transport failure.
