Fifteen women with symptomatic uterine myomas, diagnosed by clinical examination and confirmed by pelvic ultrasonography, were treated with intranasal insufflation of Nafarelin acetate, 200 micrograms, twice a day, for a total treatment period of 6 months. Treatment was evaluated with respect to subjective symptoms, changes in myoma size and uterine volume, variations in blood estradiol, FSH, LH and CA 125, and side effects. The following results were obtained: 1. All patients showed a marked reduction(p<0.001) in uterine volume. Before treatment volume measured 312.3+/-24.2cm3, after 12 weeks volume was 132.4+/-40.6cm3, and after 24 weeks it was 123.6+/-48.3cm3. 2. Blood estradiol and LH levels were decreased significantly(p<0.05) after treatment. The FSH level was decreased, but not significantly. 3. Blood CA 125 levels were increased 6 cases(40.0%) before treatment. The levels were normalized in all 6 cases after treatment. 4. Symptoms of uterine myoma disappeared or decreased. 5. Minor side effects, such as hot flushes, headache, general myalgia and fatigue, and vaginal dryness were encountered frequently although none necessitating discontinuation of treatment, These data suggest that Nafarelin acetate is useful for the treatment of uterine myoma. However, appropriate indications should be selected in the treatment of uterine myoma because the possible regrowth of uterine myoma after treatment limits the use of GnRH agonist.

PURPOSE: Thallous-201 chloride produced at Korea Cancer Center Hospital(KCCH) is used in detecting cardiovascular disease and cancer. Thallium impurity can cause emesis, catharsis and nausea, so the presence of thallium and other metal impurities should be determined. According to USP and KP, their amounts must be less than 2 ppm in thallium and 5 ppm in total. In this study, the detection method of trace amounts of metal impurities in [201Tl]TlCl injection with polarography was optimized without environmental contamination. MATERALS AND METHODS: For the detection of metal impurities, Osteryoung Square Wave Stripping Voltammetry method was used in Bio-Analytical System (BAS) 50W polarograph. The voltammetry was composed of Dropping Mercury Electrode (DME) as a working electrode, Ag/AgCl as a reference electrode and Pt wire as a counter electrode. Square wave stripping method, which makes use of formation and deformation of amalgam, was adopted to determine the metal impurities, and pH 7 phosphate buffer was used as supporting electrolyte. RESULTS: T1, Cu and Pb in thallous-201 chloride solution were detected by scanning from 300 mV to -800 mV. Calibration curves were made by using TlNO3, CuSO4 and Pb(NO3)2 as standard solutions. Tl was confirmed at -450 mV peak potential and Cu at -50 mV. Less than 2 ppm of Tl and Cu was detected and Pb was not detected in KCCH-produced thallous-201 chloride injection. CONCLUSION: Detection limit of thallium and copper is approximately 50 ppb with this method. As a result of this experiment, thallium and other metal impurities in thallous-201 chloride injection, produced at Korea Cancer Center Hospital, are in the regulation of USP and KP. Polarograph could be applied for the determination of metal impurities in the quality control of radiopharmaceuticals conveniently without environmental contamination.

The aim of our study is to achieve complete periodontal tissue regeneration by the application of BMP and resorbable membrane. Three beagle dogs aged over one and half years and weighed 14 to 16 kg were used in this study. Mandibular 1st, 2nd premolars were extracted bilaterally. Horizontal furcation defects were induced around 3rd, 4th premolars bilaterally. BMP-4 were applied in the right side with resorbable membranes and only resorbable membranes were applied in the left side respectively. Each animal was sacrificed at 2, 4, and 8weeks, after regenerative surgery. Specimens were prepared with Hematoxylin-Eosin stain and Goldner's modified Masson Trichrome stain for light microscopic evaluation. The results were as follows: 1. At 2 weeks after regenerative surgery, downgrowth of junctional epithelium was observed both in the membrane-applied site and BMP-4-and-membrane-applied site. 2. At 4 weeks after regenerative surgery, resorbable membranes were completely resolved, therefore would not prevent downgrowth of junctional epithelium. New bone formation, new cementum formation and Sharpey's fiber were observed in BMP-4-and-membrane-applied site. 3. At 8 weeks after regenerative surgery, downgrowth of junctional epithelium was observed in the membrane-applied site. But, new cementum formation was observed in the same site. The extensive regeneration of new bone, new cementum and remarkable formation of Shapey's fiber were showed in BMP-4-and-membrane-applied site. 4. Resorbable membranes were resolved via the cell-mediated processes. 5. Periodontal tissue regeneration were better achieved in the BMP-4-and-membrane-applied site than in the membrane-applied site. Within the above results, BMP-4 may have the strong capability to form the new bone and resorbable membrane may be able to prevent the bony ankylosis. However, resolution rate of resorbable membrane may not be enough to protect rapid epithelial downgrowth for ideal periodontal regeneration. In conclusion, I suggest BMP-4 may have the strong possibility to be utilized in the clinical periodontal treatments.

BACKGROUND: Pneumonia is the most common cause of death among patients with infectious disease in Korea. However, studies of pneumonia with septic shock in patients presenting to the emergency department are limited. The aim of this study was to investigate the prognostic factors associated with pneumonia with septic shock in patients presenting to the emergency department. METHODS: From January 2008 to September 2014, patients with pneumonia with septic shock admitted through the emergency department were retrospectively examined. RESULTS: Of the 561,845 patients who visited the emergency department, 398 were admitted for pneumonia with septic shock. The 28-day mortality rate in these patients was 36.4%. The independent prognostic factors were old age (>70 yrs) (odds ratio [OR], 2.42; 95%, confidence interval [CI], 1.35-4.32), Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR, 1.04; 95% CI, 1.01-1.08), leukopenia (OR, 3.63; 95% CI, 1.48-8.94), prolonged PT-INR (OR, 2.53; 95% CI, 1.41-4.54), and hypoxemia (OR, 2.88; 95% CI, 1.30-6.38). CONCLUSIONS: A poor prognosis of patients with pneumonia is associated with old age (>70 yrs), increased APACHE II score, leukopenia, prolonged PT-INR, and hypoxemia.

This study was to find out whether the rendering screen difference affect to measuring distance in a CAD program according to three types of CAD programs. Materials and methods: The model presented in ISO 12836 for dental scanner evaluation was reduced by 70%. This model was repeatedly scanned 15times using Trios II (3Shape, Denmark). Using the output STL file, 3Shape CAD, inLab 15, and ExoCAD programs were used to measure the horizontal distance (H) and vertical distance (V) between adjacent point angle, and for each experiment, three groups were set according to the CAD program type. Statistical analysis was performed using One-way ANOVA test and post hoc was performed using Dunnett T3 test. Results: In the horizontal and vertical distance measurement, there was no difference in the average of the measured values between the three groups according to the CAD program (P>.05). Conclusion: There were no effect of the difference in the rendering screen in the horizontal and vertical linear distance measurements of the inlay model on the dental CAD program.

Epidemiologic Investigation into an Outbreak of Typhoid Fever Recognized by Electronic Data Interchange in Gyeongsangbuk-do, 2003 PURPOSE: Fourteen cases of typhoid fever occurred in Gyeongsan-si, Gyeongsangbuk-do from May 22 to July 19, 2003. Especially, 6 cases were students of Y University located in Gyeongsan-si. This investigation was carried out to study the infection source and transmission of typhoid fever and to institute an effective prevention counterplan. METHODS: The authors conducted an epidemiologic survey from June 25, 2003 among the 14 cases, restaurants and employees of the whole neighborhood of Y University. Widal test was carried out for the restaurant employees and schoolmates of the 13-year-old case Miss Kim. The authors executed a pulsed field gel electrophoresis (PFGE) for Salmonella typhi cultured from 9 cases. The authors collected data about chloride and turbid levels of treated water from April to June in Gyeongsan-si water treatment plant and repair work records of waterworks pipe line in Gyeongsan-si city hall. RESULTS: All cases had used restaurants of the whole neighborhood of Y University within 2 months before the typhoid fever symptoms were developed, but the restaurant that was rarely visited by any of the patients had a case to be matched. In the results of the Widal test, 9 out of 45 of subjects (20.0%) were suspicious cases or showed a value to suggest past infection. In the results of PFGE test, there were 3 subtypes, and each subtype had a similar DNA fragments array. In all cases the patients drank tap water when they visited the restaurants. The restaurants provided drinking water from filtered tap water rather than boiled water, and all patients had drunk this water. The chlorine level of the treated water was the normal value in the Gyeongsan-si water treatment plant, but in 2 times the value was the minimum standard level. There was water pipe construction work in some regions of the whole neighborhood of Y University. The number of gastrointestinal patients in 2003 was approximately 2 times that in 2002 at the health center in Y University. CONCLUSIONS: The possibility that typhoid fever was generated in the whole neighborhood of Y University is very high. Among various possibilities, the highest possibility is the pollution of tap water intake by water leakage of a water pipe. There was no case of patient infection after strengthening of the tap water disinfection. Thorough disinfection, boiled drinking water and a periodic carrier inspection are necessary to prevent additional local occurrences of these typhoid infections.
