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.

Eosinophilia is a common finding in premature babies during the neonatal period. Serial eosinophil counts were determined in 94 hospitalized, appropriately grown premature in fants whose gestational ages ranged form 28 to 36 weeks. The incidence, severity and etiologic factors of eosinophilia were retrospectively studied in premature infants, who were divided into three groups according to their gestational age. The results were as follows: 1) Absolute eosinophilia (>700/mm3)was documented in 46.8%(44/94). 2) The duration of TRN and antibiotics was cignificantly higher in infants with eosinophilia than withour eosinophilia (p<0.05). The gestational age of the infants with eosinophilia was significantly shorter than that of the infants without eosinophilia (p<0.05). The infants with eosinophilia started with bottle feeding significantly earlier than the infants without eosinophilia (p<0.05). 3) The infants younger than 30 weeks of gestational age have greater incidence of eosinophilia (75%) than the infant with the gestational age between 34 and 36 weeks (34.3%)(p<0.05). 4) The incidence of mild eosinophilia was higher in the group with gewtational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05).Also, the incidence of severe eosinophilia was significantly higher in the group with gestational age 30 weeks or below(37.5%)than in the group with gestational age between 34 and 36 weeks(17.1%)(p<0.05). 5) Eosinophilia was more prevalent in the infants who received parenteral nutrition composed of glucose, amino acid and lipid(77.8%) than the infants who received only glucose(34.1%)(p<0.05). 6) Gestational age and birth weight were significantly lower in infants with severe eosinopilia than those of mild or moderate eosinophilia. The duration of TRN and antibiotics were significantly longer in infants with severe eosinophilia than those of mild or moderate eosinophilia (p<0.05). 7) The peak eosinophil count was observed significantly later in severe eosinophilic group (26.5 13.1 days)than in non-eosinophilic group(14.4 9.0 days)(p<0.05). The above results suggest that eosinophilia in premature infants may be the effecto of immature immunologic responses to the intravenous administration of extemal antigens like amino acid, lipid and antibiotics.

Primary progressive aphasia(PPA) can be classified into nonfluent and fluent types. The fluent PPA usually manifests as Wernicke's or transcortical sensory aphasia. We report a 61-year-old right-handed woman who presented with a fluent PPA. An aphasia test revealed fluent speech and intact comprehension but decreased repetition and naming, consistent with conduction aphasia. Other cognitive functions and activities of daily living were preserved. Brain MRI and SPECT respectively showed a focal atrophy and a hypoperfusion in the left temporal lobe.

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.

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.
