Purpose: This study examined whether the supply of healthy Korean diets for 12 weeks is effective in improving the risk factors related to serum GGT and cardiovascular diseases in patients with hypertension and diabetes. Methods: This study selected 41 patients, who were treated with hypertension and diabetes. The Korean diet was composed of cooked-rice, soup, kimchi, and various banchan with one serving called bapsang, which emphasize proportionally high consumption of vegetables and fermented foods, moderate to high consumption of legumes and fish, and low consumption of animal foods. The control group was instead instructed to "eat and exercise as usual" while following the Korean Diabetes Association's dietary guidelines with an intake that can assist in glycemic control, maintain adequate weight, and meet the nutritional requirements. The Korean diet group (21 patients) were served three healthy Korean meals a day for 12 weeks, and the control group (20 patients, who trained in the diet guideline of diabetes) maintained their usual diabetic diet. The serum GGT, blood pressure, heart rate, glycemic control data, cardiovascular risk indicators, and changes in diet measured at the four visits (week 0, 4, 8, and 12) during the course of 12 weeks were compared and evaluated. Results: The serum GGT (p < 0.001), HbA1c (p = 0.004), heart rate (p = 0.007), weight (p = 0.002), Body Mass Index (p = 0.002), body fat mass (p < 0.001), body fat (%) (p < 0.001), and free fatty acid (p = 0.007) in the Korean diet group decreased significantly after the dietary intervention compared to the control group. The amount of intake of rice, whole grains, green vegetables, Kimchi, and soybean fermented food were increased significantly compared to the control group (p < 0.001). The Korean diet group showed significant decreases (p < 0.001) in the intake of animal protein, lipid, and cholesterol derived from animal foods compared to the control group but significant increases (p < 0.001) in the intake of total calories, folic acid, dietary fiber, sodium, potassium, and vitamins A, E, and C. Conclusion: In patients with hypertension and diabetes, it was confirmed that regular eating of a healthy Korean diet helps improve the risk factors for GGT and cardiovascular diseases.

This study investigated the effect of bamboo salt (BS) on body gain, feed intake, meat composition, and blood characteristics of broiler chicks. BS was processed by roasting salt at $1,200{\sim}1,300^{\circ}C$ in a bamboo container, with the open end plugged with red clay. In total, 120 broiler chicks were assigned to four treatments. Each treatment was triplicated, with 10 chicks in each treatment group. The supplementation levels of the three BS-treated feeds were 0.1, 0.2, and 0.3%. Body weight gain slightly increased in broiler chicks fed diets supplemented with BS compared to that of the control during the overall test period. However, no significant differences were observed among treatments. Feed intake was also not significantly different among treatments. Feed efficiency was significantly (p<0.05) improved in broiler chicks fed diets supplemented with BS compared to that of the control. Body weight gain was more positively affected by the dietary BS supplement at the beginning of the experimental period than toward the end. Water intake was positively correlated with the dietary 0.3% BS level (p<0.05). Breast meat composition and cholesterol levels were also not affected by BS supplementation. The total protein, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), and total cholesterol levels in the blood were not significantly different among treatments.

Purpose : Oligodendrogliomas (ODG) are a rare, slow growing, tumor in the brain, which can be cured by complete surgical resection, but as yet it is not known if postoperative adjuvant radiation therapy (RT) is essential, We analyzed the treatment results of patients with irradiated ODG to investigate the efficacy of RT in terms of survival rates and other influencing prognostic factors. Methods and Materials : Between March 1983 and December 1997, 42 patients with ODG were treated with RT at our hospital. The RT was peformed dally at a dose of $1.8\~2.0\;Gy$, at 5 fractions per week, to a total dose of between 39.6 Gy and 64.8 Gy (mean 53.3 Gy). The ages of the patients ranged between 5 and 62 years, with a median age of 39 years. The mean follow-up period was 63.4 months (8-152 months). The Kaplan-Meier method was used to assess the survival, and 5 year survival rates (5-YSR). Log rank tests and Cox regression analyses were used to define the significance of prognostic factors. Results : The majority of ODG in this study were located in the cerebral hemisphere $(83.3\%)$. ODG are slightly more common in men than women, and commonly occurs in middle age, between the 3rd and 4th decades. It has been recommended that RT is commenced within 4 weeks following surgery (5-YSR; $86\%\;vs.\;49\%;\;p<0.03$). Histologically well differentiated, as opposed to poorly differentiated, tumors were found to have a more favorable prognosis (p<0.02). The actuarial 5-YSR was $65.3\%$ (median survival 90 months). 5-YSR for the various extents of surgical excision, followed by external RT, was superior to that of biopsy only followed by external RT $(69.9\%\;vs.\;25.6\%,\;p<0.01)$. Tumor size and location, overall elapsed irradiation days, age, sex, whole brain irradiation as a course of treatment and chemotherapy, had no influence on the 5-YSR (p>0.05). Conclusion : A local involved field irradiation with conventional fractionation, commencing within 4 weeks following surgical excision of the tumor, was beneficial for the 5-YSR, but a total radiation dose exceeding 60 Gy did not improve the 5-YSR.

It has been widely known that the seismic piezo-cone penetration test (SCPTU) is one of the most useful techniques for investigating the geotechnical characteristics including dynamic soil properties. As the practical applications in Korea, SCPTU was carried out at two sites in Busan and four sites in Incheon, which are mainly composed of alluvial or marine soil deposits. From the SCPTU waveform data obtained from the testing sites, the first arrival times of shear waves were and the corresponding time differences with depth were determined using the cross-over method, and the shear wave velocity profiles (VS) were derived based on the refracted ray path method based on Snell's law and similar to the trend of cone tip resistance (qt) profiles. In Incheon area, the testing depths of SCPTU were deeper than those of conventional down-hole seismic tests. Moreover, for the application of the conventional CPTU to earthquake engineering practices, the correlations between VS and CPTU data were deduced based on the SCPTU results. For the empirical evaluation of VS for all soils together with clays and sands which are classified unambiguously in this study by the soil behavior type classification Index (IC), the authors suggested the VS-CPTU data correlations expressed as a function of four parameters, qt, fs, $\sigma$, v0 and Bq, determined by multiple statistical regression modeling. Despite the incompatible strain levels of the down-hole seismic test during SCPTU and the conventional CPTU, it is shown that the VS-CPTU data correlations for all soils clays and sands suggested in this study is applicable to the preliminary estimation of VS for the Korean deposits and is more reliable than the previous correlations proposed by other researchers.

Purpose : To evaluate the effectiveness and tolerance of postoperative e지ernai beam radiotherapy for patients with low grade glioma of the brain and define the optimal radiotherapeutic regimen. Materials and Methods : Between June, 1985 and May, 1998, 72 patients with low grade gliomas were treated with postoperative radiotherapy immediately following surgery. Median age was 37 years with range of 11 to 76 years. Forty one patients were male and 31 patients were female with male to female ratio of 1.3:1. Of those patients, 15 underwent biopsy alone and remaining 57 did subtotal resection. The distribution of the patients according to histologic type was as follows: astrocytomas-42 patients (58$\%$), mixed oligodendrogliomas-19 patients (27$\%$), oiigodendrogliomas-11 patients (15$\%$). Two patients were treated with whole brain irradiation followed by cone down boost and remaining 70 patients were treated with localized field with appropriate margin. Ail of the patients were treated with conventional once a day fractionation. Most of patients received total tumor dose of 5000 $\~$ 5500 cGy. Results : The overall 5 and 7 year survival rates for entire group of 72 patients were 61$\~$ and 50$\~$. Corresponding disease free survival rates for entire patients were 53$\~$ and 45$\~$, respectively. The 5 and 7 year overall survival rates for astrocytomas, mixed oligodendrogiiomas, and oligodendrogiiorras were 48$\%$ and 45$\%$, 76$\%$ and 56$\%$, and 80$\%$ and 52$\%$, respectively. Patients who underwent subtotal resection showed better survival rates than those who did biopsy alone. The overall 5 year survival rates for sub total resection patients and biopsy alone patients were 57$\%$ and 43$\%$, respectively. Forty six patients who were 40 years or younger survived batter than 26 patients who were 41 years or older (overall survival rate at 5 years, 69$\%$ vs 45$\%$). Although one patient was not able to complete the treatment because of neurological deterioration, there was no significant treatment related acute toxicities. Conclusion : Postoperative radiotherapy was safe and effective treatment for patients with low grade gliomas. However, we probably need prospective randomized trial to define optimal treatment timing and schedule for low grade gliomas and select patient group for different treatment philosophies.

The study was conducted to determine the effect of community ambulation training and treadmill training on the gait ability and stroke impact scale in patients with hemiplegia due to stroke. Twenty-two patients with hemiplegia due to stroke were assigned to the community ambulation training group(n=11) or treadmill training group(n=11). Both groups were executed conventional treatment for 5 times per week for 6 weeks 30 minutes per session. Each group performed additional exercise for 30 minutes. Post treatment, compared to the treadmill training group, community ambulation training group showed significantly increased velocity, cadence, stroke impact scale(p<.05). These results support the perceived benefits of community ambulation training to augment on the gait ability and stroke impact scale of stroke patients. Therefore, community ambulation training is feasible and suitable for stroke patients.

Introduction : Rapidly growing nontuberculous mycobacteria (RGM) can produce numerous types of manifestations including a pulmonary infection. Managing a pulmonary infection due to RGM is unusually difficult to treat because the organism is invariably resistant to traditional antituberculous drugs and has a varying susceptibility to other antibiotics. The experiences of treatments for a RGM pulmonary infection with various antibiotics are also limited. This study evaluated the clinical manifestations, treatment, and the therapeutic outcomes of a RGM pulmonary infection. Subjects and method : Fifty-four cases with RGM from respiratory specimens were identified between November of 1996 and September of 2002 in the Asan medical center. The medical records and radiographic findings in 20 patients who fulfilled the diagnostic criteria of nontuberculous mycobacteria (NTM) pulmonary disease by ATS guidelines. The clinical, laboratory, and radiological parameters between subgroups. Results : Of the 20 patients, 15 were female. The mean age was 57.7 yrs (${\pm}7.5$), and all of the patients had a history of pulmonary tuberculosis. Most (90%) had an underlying lung disease. The majority of the isolates (80%) were M. abscessus. Chest radiography showed bilateral involvement in 80% of the patients. Bronchiectasis and multiple nodules were the main findings. Cavitation was present in 35% of the patients. Even though 70 % of the patients received antituberculous drugs prior to the correct diagnosis, all of the patients eventually received antibiotics. A mean of 3.5 antibiotics were given for an average of 439 days(${\pm}168$). After completing treatment, nine patients showed improvement after a mean 591(${\pm}311$) days of treatment, whereas the antibiotic treatment was unsuccessful in 2 patients. Conclusion : Many patients with a RGM pulmonary infection show an atypical pattern of radiological findings (bronchiectasis and multiple centrilobular nodules). It is very important to differentiate between M. tuberculosis and NTM and to identify the causative organisms among the NTM because a misdiagnosis can lead to an inappropriate and prolonged treatment. Combined antibiotic treatment yielded promising results, and is recommended for treating patients with a RGM pulmonary infection.

Implant overdenture exhibits higher retention, masticatory function, and patient's satisfaction compared to conventional dentures. Particularly, in treatment of severe alveolar bone resorption, implant overdenture can be considered as the first treatment option. The types of attachments used for implant overdenture can be classified into solitary type, which implants are not connected to each other, and bar type in which implants are connected. In the case of solitary type commonly used in clinical practice, parallel relationship is important. When it is not established, there is a higher risk of attachment wear, retention loss, and frequent visits for maintenance. In this case, satisfactory results have been obtained with implant overdentures using milled bar on two unparallel implants placed on the mandible.

Purpose : This study is a prospective randomized clinical trial comparing the efficacy and complication of anti-emetic drugs for prevention of nausea and vomiting after radiotherapy which has moderate emetogenic potential. The aim of this study was to investigate whether the anti-emetic efficacy of ondansetron $(Zofran^{\circledR})$ 8 mg bid dose (Group O) is better than the efficacy of metoclopramide 5 mg lid dose (Group M) in patients undergoing fractionated radiotherapy to the abdominal region. Materials and Methods : Study entry was restricted to those patients who met the following eligibility criteria: histologically confirmed malignant disease; no distant metastasis; performance status of not more than ECOG grade 2; no previous chemotherapy and radiotherapy. Between March 1997 and February 1998, 60 patients enrolled in this study. All patients signed a written statement of informed consent prior to enrollment. Blinding was maintained by dosing identical number of tablets including one dose of matching placebo for Group O. The extent of nausea, appetite loss, and the number of emetic episodes were recorded everyday using diary card. The mean score of nausea, appetite loss and the mean number of emetic episodes were obtained in a weekly interval. Results : Prescription error occurred in one patient. And diary cards have not returned in 3 patients due to premature refusal of treatment. Card from one patient was excluded from the analysis because she had a history of treatment for neurosis. As a result, the analysis consisted of 55 patients. Patient characteristics and radiotherapy characteristics were similar except mean age was $52.9{\pm}11.2$ in group M, $46.5{\pm}9.5$ in group O. The difference of age was statistically significant. The mean score of nausea, appetite loss and emetic episodes in a weekly interval was higher in group M than O. In group M, the symptoms were most significant at 5th week. In a panel data analysis using mixed procedure, treatment group was only significant factor detecting the difference of weekly score for all three symptoms. Ondansetron $(Zofran^{\circledR})$ 8 mg bid dose and metoclopramide 5 mg lid dose were well tolerated without significant side effects. There were no clinically important changes In vital signs or clinical laboratory parameters with either drug. Conclusion : Concerning the fact that patients with younger age have higher emetogenic potential, there are possibilities that age difference between two treatment groups lowered the statistical power of analysis. There were significant difference favoring ondansetron group with respect to the severity of nausea, vomiting and loss of appetite. We concluded that ondansetron is more effective anti-emetic agents in the control of radiotherapy-induced nausea, vomiting, loss of appetite without significant toxicity, compared with commonly used drug, i.e., metoclopramide. However, there were patients suffering emesis despite the administration of ondansetron. The possible strategies to improve the prevention and the treatment of radiotherapy-induced emesis must be further studied.

This study was designed to investigate the effects of korean pueraria radix extract in Pb administered rats. Forty-two male Sprague-Dawley rats weighing $100{\pm}10g$ were used for this experiment and divided into following 6 groups; control group, 3% pueraria radix group(3% pue.), 100 ppm and 200 ppm alone pb group, 100 ppm and 200 ppm alone pb group with 3% pue. Tissue weight of liver, lung, stomach, heart, kidney and spleen of pb exposed rats were reduced by 3% extracts of pueraria radix group. The Pb content in the rats tissue of pb alone administered group was lower than in the rats tissue of pb group with 3% pue. GPT and GOT were increased in pb-administered group and lower in the 3% extracts of pueraria radix group. LDH was lower in the 3% extracts of pueraria radix-pb group than in the pb group. ChEase was higher in the 3% extracts of pueraria radix group than in the pb alone administered group.
