This study was carried out to investigate the heavy metal contents and their correlations between paddy soil and brown rice near the Kum-River area. In this study, eighty soil samples and forty brown rice samples were taken from the paddy soil. The contents of heavy metals were measured by flame atomic absorption spectrophotometry. The results were as follows: 1. The average contents of soluble heavy metals in surface soil were Cd 0.19, Cu 15.31, Zn 18.10 and Pb 9.08 ppm. The average contents of soluble heavy metals in subsurface soil were Cd 0.19, Cu 14.52, Zn 17.75 and Pb8.11 ppm. There wan no statistically significant difference between the two layers. 2. The contents of Cu, Zn and Pb of Taejeon(S6) and Cd of Sinbyung(S5) in surface soil were higher than those of other areas. The contents of Cd and Cu of Taejeon(S6) and Zn and Pb of Kumnam(S3) in brown rice were higher than those of other areas and four heavy metals in soil and brown rice of Simchon(S7) were lower than those of other areas. 3. The ratio of soluble contents(Cd : Cu : Zn : Pb) in surface soil was 1 : 79 : 93 : 47, that of soluble contents in subsurface soil was 1 : 79 : 94 : 43, and that of total contents in brown rice was 1 : 84 : 294 : 12. 4. The correlations of the content between soluble heavy metals in surface(0-15 cm depth) soil total heavy metals in brown rice was found to be order of Cd>Cu>Zn>Pb. The correlations of the content between soluble heavy metals in subsurface(20-30 cm depth) soil and total heavy metals in brown rice was found to be order of Cu>Cd>Zn>Pb.

The operative treatment of orbital blowout fracture involves restoration of intra-orbital soft tissue and bony structural integrity. In extensive blowout fracture, postoperative edema and subsequent increase of intraoribital pressure may sometimes lead to displace the implant. To prevent postperative displacement of the implant, we tried reinforcing the implant using a buttress consisting of micro-titanium mesh and titanium mesh in 13 cases of extensive orbital blowout fracture, including medical wall fracture (6), inferior wall fracture (5) and inferomedial wall fracture (2). A small thin titanium buttress was inserted beneath the implant at the point where intraorbital pressure was involved maximally. It was usually placed superoinferiorly in a medial wall fracture wall fracture, mediplaterally along th posterior ridge of bony defect in an inferior wall fracture, and anteroposteriorly in an inferomedial wall fracture. No evidence of implant displacement after operation was noted in any cases and this was confirmed by postoperative computed tomographic scan. Also, any complication by a titanium buttress did not occur. Orbital implant reinforcement using a titanium buttress may be an available technique for preventing implant displacement in reconstruction of extensive orbital blowout frature.

PURPOSES: This study examined the relationship between risk behaviors and sexual knowledge, sexual attitudes, and sexual experiences of male high school students. METHOD: A cross-sectional, descriptive study was conducted. Data were collected from 2 male high schools in metropolitan Gwangju. Five hundred forty-eight boys were enrolled in this study. Descriptive statistics, factor analysis, t-test or ANOVA, and Pearson's correlation were used for data analysis. RESULTS: The mean sexual knowledge and sexual experience scores were relatively low, 0.60 out of 1 point, and 0.75 out of 4 points, respectively. Three attitude types of the students were identified: permissible, conservative and pleasure seeking attitude. The score of the permissible type was affected by the subjects' exposure to pornographic material. The score of the conservative type was affected by alcohol consumption and acquaintances with a heterosexual friend. The score of the pleasure seeking type was affected by their exposure to pornographic material, alcohol consumption, smoking, going to a video-room, and acquaintances with a heterosexual friend. There was a negative correlation between the permissible type and sexual knowledge, and a positive correlation between the conservative and pleasure seeking types and sexual experience. CONCLUSION: Male high school students who have been exposed to risk behaviors have a higher likelihood of indulging in sexual activity, and the pleasure seeking type appears to be related to sexual experience. An educational program may be needed to prevent risky behaviors and sexual experiences in male high school students considering their sexual attitude type.

Syringomyelia was described by Etienne et al in 1954 and was named by Ollivier in 1827 by reason of the pathologic cavitation of cord. Also it is considered a very chronic and irregulary progressive disease of the spinal cord of unknown cause which has predilection for the cervical and lumbar enlargements. The patient of 19 years old male had been suffered from the painless, severe swelling and instability of right elbow after trauma on right elbow, aud had complained of the sensory and temperature dissociation, muscle weakness with clawing hand in right upper extremity and scoliosis of mild degree. These symptoms and findings were same as those of the classic syringomyelia. Therefore the syningomyelia which is relatively rare in incidence will be reviewed by this report with the references.

PURPOSE: Untreated deep vein thrombosis (DVT) is associated with morbidity and mortality, such as pulmonary embolism and post-thrombotic syndrome. Anticoagulation therapy is efficient for reducing thrombus propagation but is insufficient for clot lysis or preventing post thrombotic syndrome. Current catheter-directed thrombolysis is an important DVT treatment. We compared the outcomes between anticoagulation therapy and DVT catheter-directed thrombolysis. The purpose of this study was to evaluate treatment outcomes in patients with symptomatic DVT who had undergone catheter-directed thrombolysis. METHODS: From January 2003 to January 2009, we retrospectively reviewed 91 patients who had been admitted and treated for DVT in our hospital. We divided 91 patients into two groups according to treatment method; 42 patients (46.2%) were treated with only anticoagulation, and 49 patients (53.8%) were treated with catheter-directed thrombolysis. We compared the results of the two treatments groups. The results included gender, symptom onset, age, location, complications, risk factors, days to improved patient symptoms and patency. All patients underwent Doppler sonography or CT-venography at 3 and 6 months to evaluate venous patency after treatment. RESULTS: 49 patients who underwent catheter-directed thrombolysis for DVT had more symptom-relief days (25.00 days, P<0.001). The 43 patients (88%) of the catheter-directed thrombolysis group showed more complete resolution on Doppler sonography or CT-venography after 6 months (P=0.001). We obtained better clinical outcomes in the catheter-directed thrombolysis group than in the anticoagulation only group. CONCLUSION: Catheter-directed thrombolysis is an effective treatment for acute DVT.

PURPOSE: The purpose of this study is to evaluate the CT and MR findings of brain absecss with emphasis on the thickeness and signal intensity of abscess wall. MATERIALS AND METHODS: Twenty CT scans and seven MR studies of 23 patients with brain abscess (27 abscesses) were retrospectively reviewed with respect to thickeness and signal intensity of abscess wall, shape and size of abscess, etc. Thickness of abscess wall was measured in the greatest abscess diameter on the CT scans and MR images obtaihed after intravenous administration of contrast material. RESULTS: Enhancing abscess wall was 2mm--6mm (average 3mm) thick. The abscess wall was uniform in thickness in 14 cases (52%), thinner in the roedial wall than lateral wall in 8 cases (30%), and thicker in the medial wall than lateral wall in 5 cases (18%). Signal intensity of abscess wall was isointense relative to gray matter on Tl-weighted MR images and hypointense on both proton- and T2-weighted MR images in 7 out of 8 lesione (88%). The inner margin of the abscess wall was smooth in 14 (52%) and irregular in 13 lesions (48%). The outer margin was smooth in 15 (55%) and irregular in 12 lesions (45%). The size of the abscesses was variable, ranging from lcm to 6cm in diameter. They were round (16 cases), elliptical (6 cases), or multilobulated (5 cases) in shape. Satellite or daughter abscesses were found in 5 patients. CONCLUSION: Abscess wall showed variable thickness in the medial and lateral walls with no specific findings. Other CT and MR findings were also nonspecific, although hypointensity of abscess wall on T2-weighted MR images may be helpful in diagnosis of brain abscess.

BACKGROUND: This study was undertaken to compare nosocomial infection rates between intensive care units of military and civilian hospitals. METHODS: From July to December 2000, we surveyed the intensive care unit of Armed Forces Capital Hospital (AFCH). We compared device use ratios and device-day infection rates with those of Korean Society for Nosocomial Infection Control (KOSNIC) and National Nosocomial Infections Surveillance (NNIS) system. RESULTS: During the period of study, 185 cases were admitted and 24 nosocomial infections were detected: 7 cases of pneumonia, 6 urinary tract, 3 blood stream, 3 cardiovascular system, 3 surgical site infections, 1 skin and soft tissue, and 1 central nervous system infection. Ventilator, urinary catheter and central venous catheter use ratios were 0.14 (95% confidence interval, 0.12-0.16), 0.58 (0.56-0.60) and 0.33 (0.31-0.35). The ratios of NNIS were 0.41, 0.67 and 0.50. Ventilator-, urinary catheter- and central venous catheter-day infection rates were 18.69(11.36-53.32), 6.65 (3.36-14.20) and 1.95 (1.44-9.92). However, the rates of KOSNIC were 9.93, 5.29 and 3.62. The rates of NNIS were 11.24, 6.14 and 5.55. CONCLUSIONS: In AFCH ventilators were used less frequently than NNIS, but more ventilator-associated pneumonia were developed than KOSNIC and NNIS.
