In case of submucosal tumor, adenoma and atypism, we can't frequently use the snare polypectomy for treatment of them. Adenoma and atypism are premalignant, so other therapeutic modalities are necessary for resection of them. We have perfortned endoscopic mueosectomy such as strip biopsy, and "O"ring ligation on various mucosal lesions of upper GI tract in 23 patients(11 men, l2 women) from June 1993 to December l994. Fourteen patients wbo had adenoma were followed up endoscopically for 6 months to 24 months(mean: 14 months). The results were as follows: 23 patients(27 lesions) were enrolled in this study. Mean age was 50.3(range 32-74 years). The method of mucosectomy was strip biopsy in 19 cases(21 lesions), and "O"ring ligation in 4 cases(6 lesions). The rate of complete resection was 88.9%. If adenomas were resected incompletely, we added a laser therapy. There was no recurrence except a case in which carcinoma was detected on the other site during follow-up. No serious compication occurred such as massive bleeding or perforation. Based on the above results, the endoscopic mucosectomy is considered to be a safe and effective modality in the treatment of the flat polyps of upper GI tract and could be used for prevention of gastric cancer.

This study was aimed to elucidate the relationship between combinations of treadmill speed-grade and oxygen consumption(Vo2). Twenty athetic and 20 non-athletic male college students aged 19-24yr were employed to exercise on a treadmill using 4 speeds(4.02, 5.47, 6.76 and 8.05km/h) and 5 grades(0, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The Vo2, heart rate, stride frequency and stride length were measured during the last min of each 3-min stage. Vo2increased linearly with increasing speed and grade showing significant multiple correlations in nonathletes(Vo2=3.64x+0.831y+0.031xy-7.03, R=0.98, P<0.01) and athletes(Vo2=3.48x+0.324y+0.112xy-5.74, R=0.99, P<0.01). Stride frequency and length tended to increase with increasing speed except for the transition from walking to runnig at 8.05Km/h at which the stride frequency ran up much higher with the stride length getting lower than at 6.76Km/h. Heart rate increased linearly with increasing Vo2. The rate of increase was higher during walking than during running. These results indicate that athletes have higher rate of increase in Vo2than nonathletes at near-maximal exercise and may be used as a guideline in predicting maximum oxygen comsumption and in prescribing exercise intensity.

Bilateral calcifications of the basal ganglia, the thalami, the dentate nuclei of the cerebellum, and the white matter of the cerebral hemisphere characterize Fahr's disease. The common clinical manifestations of the disease are movement disorders accompanied by cognitive impairment and mood disorder. Herein we report a case of Fahr's disease with atypical clinical manifestations. The patient was a 48 year-old man who presented with behavioral changes. His neurological examination showed no focal neurological deficits except for frontal dysfunctions. Abnormal involuntary movement was absent. Neuroimaging work-ups were compatible with Fahr's disease.

BACKGROUND: One of the most frequent cytogenetic abnormality in acute myeloid leukemia (AML) is t(8;21) (q22;q22), with rearrangement of the AML1 gene on chromosome 21q22 and the ETO gene on chromosome 8q22. In adult AML1/ETO-associated leukemia patients, chemotherapy alone results in cure rates that are comparable to or better than those achieved with allogenic bone marrow transplantation. Despite the relatively good prognosis of AML1/ETO fusion transcript, relapse of leukemia remains the most common cause of treatment failure. Monitoring minimal residual disease (MRD) in leukemia has two main aims : to assess the effectiveness of treatment and to detect early signs of relapse. Reverse transcription-polymerase chain reaction (RT-PCR)- based methods is the rapid and sensitive method in the identification of this molecular abnormality. The purpose of this study is to ensure the usefulness of the RT-PCR technique for detecting MRD in AML1/ETO-associated leukemia patients in remission and to establish the correlation of the serial detection of AML1/ETO fusion transcripts after complete remission and long-term outcome. METHODS: From the bone marrow aspirates of 25 AML1/ETO positive AML patients, serial detection of AML1/ETO fusion trascripts was performed using RT-PCR. RESULTS: AML1/ETO fusion transcripts were positive in 14 cases who did not show t(8;21). In serial assay, AML1/ETO fusion transcripts was positive in 9 cases and negative in 13 cases at 10 weeks after complete remission. AML1/ETO fusion transcripts (+) group has 107.4+/-18.2 months suvival and AML1/ETO fusion transcripts (-) group has 47.3+/-18.0 months survival. However, there is no significance (P=0.11). CONCLUSION: This study suggests that the early negative conversion of AML1/ETO fusion transcript may be the good prognostic predictor. The RT-PCR technique is useful for detecting minimal residual disease in leukemia patients in remission and it may improve the therapeutic strategy for leukemia.

BACKGROUND: Intravenous lidocaine has been reported previously to inhibit neuropathic pain. But it`s analgesic effect in postoperative pain has provided controversial results. The object of this study was to define the analgesic effect of intravenous lidocaine in addition to morphine on postoperative pain control. METHOD: Female patients scheduled for total abdominal hysterectomy were randomly assigned to one of two groups to be studied in a double-blind manner. Group M (n=20) and Group M+L (n=18) received intravenous morphine (0.1 mg/kg) or intravenous morphine (0.1 mg/kg) + lidocaine (30 mg), respectively, after closure of the peritoneum. Continuous infusion of morphine (1.5 mg/hr) or morphine (1.5 mg/hr) + lidocaine (60 mg/hr) was started immediately after i.v. bolus injection, respectively, until the end of the operation. Postoperative pain was managed with a PCA pump (Walkmed, Medex, USA), setting the basal rate of morphine (0.5 mg/hr) + bolus dose (1.5 mg) and lock out time of 10 min in group M, adding the lidocaine (basal rate: 20 mg/hr and bolus dose: 60 mg) to the same dose of morphine as group M in group M+L. Postoperative visual analogue pain scores (VAS), analgesic requirements and side effects were examined for 2 days postoperatively and compared between groups. RESULTS: VAS at movement were significantly less (p< 0.05) in group M+L than in group M of 2, 12, 24, 36 and 48 hrs after surgery. Patient-controlled morphine cumulative consumption in group M+L was significantly less (p< 0.05) than in group M for 24 hours (26.3 mg vs 35.3 mg) after the operation (p<0.01). CONCLUSIONS: Intravenous lidocaine reduces postoperative pain at movement and analgesic requirements. These results suggest that low-dose adminstration of i.v. lidocaine attenuates the postoperative hyperalgesic state.

PURPOSE: The aim of this study was to assess the mid-term results of primary cementless total hip arthroplasty (THA) using Summit® stems. MATERIALS AND METHODS: One hundred twenty-eight arthroplasties in 121 patients who were performed THA from December 2004 to March 2013, were reviewed retrospectively a minimum of 4 years follow-up (mean age, 60.3 years; mean postoperative follow up period, 86.3 months). For a clinical evaluation, the Harris hip score (HHS) was used to assess outcome. Radiographic evaluation was done through spot welds, subsidence, stress shielding, canal filling. RESULTS: The mean HHS was 69.8 points preoperatively, and it improved significantly to 96.3 points at the final follow-up. Postoperatively, 10 patients experienced thigh pain and 7 patients showed a moderate limping gait. There was not only early stem subsidence but there was no more subsidence at last follow up. One hundred eighteen hips showed radiographic signs of stem bone ingrowth, and 10 hips showed fibrous ingrowth at the last follow-up. Stress shielding occurred in 85 hips and third degree stress shielding was observed in 6 hips. Complication arose in 10 hips due to dislocation. Although revisions due to recurrent dislocations led to acetabular component revision in one hip, no revisions arose due to isolated aseptic loosening of the femoral component. CONCLUSION: The clinical and radiological mid-term results of primary THA using Summit® stems revealed solid initial fixation and bone ingrowth stable fixation. Considering the satisfactory clinical results, Summit® stems may be a good treatment option in Korean patients who were required hip arthroplasty

As the incidence of diet-related diseases increase, much attention has been focused of traditional foods. Traditional foods are ultimately based on local foods. However, there has been little study looking into the recipes and nutritional value of local foods. Therefore, the present study was designed to standardize recipes and analyze the nutrients of some representative local foods of Cheollabuk-do Province. Their foods were Cheonju pibimpap, kongnamulgukpap, minmuljangokui, aejeotchim and aguytichim. Test recipes for each food were prepared, being based on various information obtained from personal interviews, literature surveys of restaurant recipes. Then test recepe was subjected to sensory evaluation. All characteristics of each food were judged as "satisfactory". The analysis of nutrient composition revealed that in general energy content was low whereas protein content was as high as recommended reguirement in all foods except for kongnamulgukpap. Vitamin content was generally high but contents of calcium and iron were relatively low in all foods. Cheonju pibimpap was rich in dietary fiber. Dietary fiber content of Cheonju pibimpap was 16.6g per serving size. All foods contained considerable amounts of essential amino acids. The major fatty acide were oleic acid, linoleic acid and glutamic acid, oleic acid being the highest in terms of composition ratio.

BACKGROUND: Photoaging skin is clinically characterized by wrinkled, dry, inelastic and irregularly pigmented skin, skin tumor and histologically by increased epidermal thickness, nurnerous fibroblasts, mast cells and inflammatory cells in the upper dermis, elastosis, degeneration of collagen fibers, increased proportion of type III collagen fibers in the dermis and increased numbers of keratinizing cysts in the lower dormis of hairless albino mouse skin. Chronic exposure to UVB induces photoaging skin and sunscreen agents are used to prevent photodamage to skin and reduce the incidence and extent of the chronic photoaging effects. OBJECTIVE: To evaluate the photoaging effects of UVB on the skin and to assess the ability of sunscreen agents to protect the skin from photoaging, we examined the clinical, histological and quantitative changes in collagen in the skin of Albino hairless Skh: HR-1 mice. MATERIALS AND METHODS: The experimental animals were male Albino hairless Skh: HR-1 mice, 12 weeks old. The control group was a chronologically aging group which had not been affected by UVB irradiation. The non-protected group was irradiated with UVB, a half of MED, 3 times weekly(Monday, Wednesday, Fr iday), for 12 weeks. To assess the photoprotective effects of sunscreen agents, the control group, the non-protected group and the sunscreen agent-applicated groups were compared to each other clinically, histologically, and by quantitative collagen analysis. An early increase in type III collagen during UVB irradiation was determined by cyanogen bromide digestion of the whole skin, sodium dodecyl sulfate-polyacrylamide gel electrophoresis and densitometry. RESULTS: Clinically, the skin of the mice in the non-protected group showed mild changes caused by photoaging. Histoloically, the non-protected group showed increases in the size and number of keratinizing cysts in the lower dermis and increases in the mast cells in the upper dermis compared with the control group. However, no significant findings of increased epidermal thickness, inflammatory cell infiltration, elastic fiber change or degeneration of collagen fibers were shown. By the 12th week, four of the total of nine mice in the non-protected group developed at least one tumor. The sunscreen agent applicated groups showed slightly photoprotected effects clinically and histologically. In the collagen analysis, the proportion of type III collagen was significantly increased in the photoaging skin of mice in the non-protected group compared with the control group. Mice in the sunscreen agent applicated groups showed a significantly decreased proportion of type III collagen compared with the non-protected group. CONCLUSION: To summarize, UVB exposure of the skin induces photoaging. The number and size of keratinizing cysts increased in the photoaging skin of hairless albino mice. There was also a quantitative change in the collagen fibers. The use of sunscreen agents decreases the photoaging effects of UVB on the skin.
