The purpose of this study was to find the distribution and measurement of compressive and tensile stress when intrusi- on arch wire is forced engage with upper canine and to analysis stress at each section through FEM. And we compare compressive and tensile ratio at each section. The results were as follows. 1. At FA point and cemento-enamel junction of upper canine, compressive and tensile force ratio is about the same. 2. At apex, compressive force is the four times as tensile force. ; In intrusion, we show root resorption at apex. 3. At Cemento-enamel junction, the compressive and tensile force show the maximun value except FA point.

A clinical and histopathological study was performed on ninety-four patients with nephrotic syndrome (91 idiopathic and 3 secondary) who were admitted to Department of Internal Medicine, Yeungnam University Hospital during the period of nine years, from January 1985 to May 1994. The results were as following. 1. the ratio of male to female was 1.76:1. In young age group, minimal change was the most predominant type. In old age group, membranous glomerulonephritis and focal glomerulosclerosis were predominant types. 2.- The primary nephrotic syndromes were 96.8% and secondary nephrotic syndromes were 3.2%. Histopathologic findings of 94 renal biopsy tissue were classified into minimal change (43.6%) mesangial proliferative glomerulonephritis (29.8%), membranous glomerulonephritis (12.8%), Typel membranous proliferative glomerulonephritis (4.3%), focal glomerulosclerosis (3.2%) .and others (6.4%). 3. The response of eighty-six patients treated with steroid showed complete remission in 51.2%, partial remission in 20.9%, steroid dependent in 2.3%, and no effect in 25.6% of cases respectively. The response to steroid therapy was most effective in the patients with minimal change lesion. 4. In the patient with membranous proliferative glomerulonephlitis, long-term angiotensin converting enzyme inhibitor treatment showed less deterioration of renal function.

PURPOSE: Matrix metalloproteinase-2 (MMP-2) and MMP-7 have been implicated in tumor growth and metastasis. This study aimed to investigate the expressions of MMP-2 and -7 in colorectal cancer and to evaluate their values as prognostic markers. METHODS: Immunohistochemical staining for MMP-2 and -7 was done in 144 resected colorectal cancer specimens. Clinicopathological data and survival results were compared with regard to the expression results. RESULTS: The expression rates of MMP-2 in tumor cells in the tumor center and the tumor border were 16.7% and 38.9%, respectively. That of MMP-2 in stromal cells was 27.8%. MMP-7 immunoreactivities of tumor cells in the tumor center and the tumor border were 6.9% and 23.6%. The expressions of MMP-2 and MMP-7 were correlated. MMP-2 expression in stromal cells was more increased in the distal part of the colorectum: 8.8% in right colon cancer, 29.5% in left colon cancer and 36.4% in rectal cancer. MMP-2 expression of tumor cells in the tumor border was correlated with T-stage. MMP-7 expression of tumor cells in the tumor border was increased in case of infiltrative cancer compared with fungating tumor. The expression patterns of MMP-2 and -7 were not correlated with other clinicopathological factors, including tumor markers, node metastasis, distant metastasis, lymphatic invasion, tumor differentiation, and recurrence. No significant associations between the overall and disease-free survival rates and the MMP-2 and -7 expression patterns were noted. CONCLUSION: The high expression rates of MMP-2 and -7 in tumor borders suggest that MMP-2 and -7 have some role in tumor invasion, but in this study, MMP-2 and -7 did not appear to be significant predictors of prognosis in colorectal cancer.

The chest wall and breast asymmetry varies from severe pectus deformities to an isolated breast hypoplasia. In addition to the chest abnormality, a natural-looking breast is the aesthetic challenge in women. Considering that the most common indication of operations is an aesthetic one, any procedures leaving much scars and deformities at the donor site aren't preferred by patients. A 31-year-old female had a 4 x 10 x 2.5 cm sized pectus-excavatum deformity on her right chest, and a slightly hypoplastic breast compared with the left one. The nipple of her right breast was located supero-medially and pectoralis muscles were preserved to some degree at the right side. Through a bilateral submammary and subxiphoid incision, the deformed cartilage was resected from 3th to 7th rib bilaterally and chondrotomy was done at the sternum partially. After this modified Ravitch's technique, two-metal pins were fixated between right 4th~5th ribs and left 4th rib, and the depressed sternum was elevated over the metal pins. The deficient volume of her right breast was corrected by inserting a siliconegel breast implant (120 cc) submuscularly to restore a adequately projected breast. The results of twelve months' follow-up demonstrated a symmetric and well- projected breast. There were no significant chest wall depression or capsular contracture. Restoring a fundamental bony structure would decrease the amount of augmentation needed in the soft tissues. And a silicone-gel breast implant may be used as an the alternative material for whose axillary fold is preserved to some degree.

Blue Rubber Bleb Nevus syndrome, or Bean's syndrome is a very rare disease characterized by an association of 1) hemangioma cutis in which the nevi feel like rubber blebs; 2) hemangiomas of the digestive organs; 3) iron-deficiency anemia due to hemorrhage from the digestive tract. Sometimes, the bleeding is so severe and massive that the patient needs blood transfusions and/or emergency operations. We present a 29-year-old man with Blue Rubber Bleb Nevus syndrome. This patient was admitted to out hospital due to recently aggrevated dizziness and intermittent rectal bleeding. Multiple bluish tumors were noted on the palm, sole and glans penis. Laboratory examination revealed severe iron-deficiency anemia. Barium studies revealed multiple polypoid masses in the stomach, small bowel and colorectum. On esophagogastroduodenoscopy and colonoscopy, three or four dozens of hemangiomas with variable size and shape were noted in the stomach, duodenum at or around the ampulla of Vater and colorectum. This patient was of particular interest because rectal bleeding occurred from rectal lesion which protruded out of anus and caused bleeding during defecation, and which showed as a 2.0 cm Yamada type III polypoid lesion. Endoscopic ultrasonography confirmed us that this lesion was confined to the mucosa and submucosa without extension into muscle layer. Endoscopic polypectomy of this lesion was performed because which considered as the main focus of current rectal bleeding. He was discharged without any complication and 4 months later, he was well without rectal bleeding and his hemoglobin level increased upto 13.5 g/dl. To our knowledge, this is the first case of Blue Rubber Bleb Nevus syndrome in Korea.

We analysed 8 cases of gastrointestinal cytomegalovirus(CMV) infection including one autopsy, three surgically resected and four endoscopic biopsy cases. Involved sites were colon in four,stomach in three and small intestine in one. Three of them were associated with immu-nosuppressed condition but others had no clinical evidence of immune deficiency. Multiple aphthous mucosal ulceration was a common presentation, but one revealed a mucosal ulcer with segmental narrowing and thickening of wall. Microscopically, six showed cytomegalic inclusions in endothelial cells and fibroblasts, one in mucosal epithelial cells and the remaining one in both endothelial cells and mucosal epithelial cells. Immunohistochemical staining using monoclonal antibody against CMV confirmed postive result in seven cases. Serum IgM anti-CMV antibody was elevated in one case. We conclude that gastrointestinal CMV infection is currently not a rare condition and frequently associated with non-immunosuppressed condition, and thus a thorough histologic examination is required especially in the gastrointestinal ulcerative lesion. Once cytomegalic inclusion is suspected, immunohistochemical identification of CMV seems essential for specific diagnosis.

The clinical symptom complex characterized by syncopal attacks and sudden death in patients with electrocardiographic anomalies, especially a prolonged Q-T interval is known as the Romano-Ward syndrome. When a similar symptom complex is accompanied by congenital deafness, it is called Jervell and Lange-Nieisen syndrome. This study was undertaken to investigate the investigate the incidence of the latter syndrome in the Seoul area. A total of 1,013 children with congenital deafness who attend schools for the deaf were studied by analyzing their electrocardiograms. A corrected Q-T interval of> or =0.44 seconds was defined as a prolonged Q-T interval. The overall incidence of long Q-T syndrome observed in the deaf in the Seoul area was 0.49% as compared to 0.25% reported from elsewhere in the world. The mean age of patients with long Q-T syndrome was 11.3+/-5.9 years and the first syncopal attacks was 4.6+/-1.1 per patient. A valsalva maneuver and exercise tests in the test group were associated with significant changes in T wave configuration and prolonged Q-T intervals while similar changes were not observed in the control group. A larger survey is needed to derive more statistically significant conclusions.
