PURPOSE: The purpose of this study was to analyze teaching status and knowledge about children with Attention Deficit Hyperactivity Disorder (ADHD) in elementary school teachers. METHODS: The participants of this study were 204 elementary school teachers in Busan. From July to September 2010, the researchers collected data by using self-report questionnaires consisted of questions about their teachers' characteristics and teaching status and KADDS (36 items) developed by Sciutto, Terjesen and Frank. Frequency, percentage, arithmetic mean, standard deviation, t-test and ANOVA were used to analyze the data using SPSS WIN 16.0 program. RESULTS: Less than 50% of the participants had previous education on ADHD. According to this experience, there were significant differences in participants' knowledge about children with ADHD (t=4.703, p<.001). For the 36 items, participants had an average of 19.19+/-4.58 points out of a possible 36. Moreover, lack of knowledge about teaching children with ADHD and communication problems with the parents of these children were considered to be the most disturbing factors. CONCLUSION: These results suggest that networks among teachers, parents and medical care professionals should be established. The results also indicate that educational programs for elementary school teachers should be developed in order to identify and teach children with ADHD appropriately.

PURPOSE: This study investigated the effect of reducing cisplatin induced nephrotoxicity with DWP-04 that is the compound of Schizandrin C derivative biphenyldimethyl dicarboxylate (DDB), glutathione and selenium. For the purpose of observation is that how DWP-04 has influence on mechanism of reducing cisplatin induced nephrotoxicity with renal function test, free radical formation and detoxification enzyme system in renal tissue. METHODS: Five groups of rats were dosed with vehicle, cisplatin (2 mg/kg i.p.), cisplatin+DWP-04 (100, 200 mg/kg po), or cisplatin+sodium thiosulfate (200 mg/kg i.p.) daily for 4 weeks. RESULTS: Serum creatinine, lactate dehydrogenase and activity of hydroxy radical increased in the cisplatin group and suppressed in the cisplatin+DWP-04 group compared to the cisplatin group. The renal tissue concentration of lipid peroxidase and lipofuscin were increased in the cisplatin group compared to the other groups. The activity of aminopyrine N-demethylase, aniline hydroxylase, aldehyde oxidase and xanthine oxidase, of which free radical formation system in kidney was also decreased in the cisplatin+DWP-04 group compared to the cisplatin and cisplatin+sodium thiosulfate group. The activity of detoxification system of free radical, such as glutathione S-transferase, superoxide dismutase, catalase and glutathione peroxidase were markedly increased in the cisplatin+DWP-04 group than the cisplatin and the cisplatin+sodium thiosulfate group (p<0.05). CONCLUSION: It can be concluded that the mechanism of decreasing cisplatin-induced nephrotoxicity by DWP-04 is that the decreasing of the amount of lipid peroxide and lipofuscin in the renal tissue by increasing activity of the antioxidant defense system and the decreasing of reactive oxygen species by increasing detoxification enzyme activity.

PURPOSE: The purpose of this study was to examine the effects of exercise intervention, including dumbbell(weight lifting), walking, and yoga, on the body composition, physiologic factors, body image, and perceived health in the community-dwelling women. METHOD: This study utilized pretest-posttest design with three types of exercise interventions. The types of exercise intervention included dumbbell, walking, and yoga. RESULTS: A total of 136 subjects were included: 49 for dumbbell, 67 for walking, and 20 for yoga. As measures of body composition, BMI, body weight, and body fat rate were significantly improved only after dumbbell intervention(p<.01). Systolic blood pressures were significantly decreased in the groups of dumbbell and walking. Diastolic blood pressure was significantly declined only in the walking group. Vital capacities and body image were improved in all groups(p<.01). However, total cholesterol levels were not improved in all groups(p>.05) and none of the measures for perceived health state were not significantly changed in all groups(p>.05). CONCLUSION: From the findings of this study, it was demonstrated that the effects of exercise interventions were differentiated by their types and variables to be affected. Therefore, future studies that apply the tailored exercise intervention to each age-categorical group are needed.

Contrast-enhanced multi-detector row spiral computed tomography (MDCT) was introduced as a promising noninvasive method for vascular imaging. This study examined the accuracy of this technique for detecting significant coronary artery stenoses. Both MDCT (Sensation 16, Siemens, Germany, 12 x 0.75 mm collimation and 0.42 sec rotation speed, 120 kV, 500 effective mA, and 2.7 mm/rotation table-feed) and invasive coronary angiography (CAG) were performed on 61 patients (mean age 59.2 +/- 10, 44 men) who were suspected of having coronary artery disease. All patients were treated with atenolol (25 - 50 mg) prior to imaging and the heart rate was maintained below 65 beats per minutes during image acquisition. The images were reconstructed in the diastole around TI - 400 ms with a 0.5 mm increment and a 1.0 mm thickness. All coronary arteries with a diameter of 2.0 mm or more were assessed for the presence of a stenosis (> 50% luminal narrowing). Two independent radiologists who were unaware of the results of the invasive CAG evaluated the MDCT data, and the results were compared with those from the invasive CAG (interval 1- 27, mean 11 days). An evaluation of the CT coronary angiogram (CTCA) was possible in 58 of the 61 patients (95%). Image acquisition of the major coronary arteries including the left main trunk was available in 229 out of 244 arteries. Invasive CAG showed that 35 out of 58 patients had significant coronary artery stenoses by. patient analysis of those who could be evaluated showed that CT coronary angiography correctly classified 30 out of 35 patients as having at least 1 coronary stenosis (sensitivity 85.7%, specificity 91.3%, positive predictive value 93.8%, negative predictive value 80.8%). By analyzing each coronary artery, CAG found 62 stenotic coronary arteries in the 229 coronary arteries that could be evaluated. MDCT correctly detected 50 out of 62 stenotic coronary arteries and an absence of stenosis was correctly identified in 156 out of 167 normal coronary arteries (sensitivity 80.6%, specificity 93.4%, positive predictive value 81.9%, negative predictive value 92.8%). The non-invasive technique of MDCT for examining the coronary artery appears to be a useful method for detecting coronary artery stenoses with a high accuracy particularly with the proximal portion and large arteries.

OBJECTIVE: Ultrasonography has benefit in detecting soft tissue abnormalities within the joints, which cannot be assessed by conventional X-ray. In this study, we investigated the relationship between soft tissue and/or bony abnormalities on ultrasonography and biochemical markers of synovium and cartilage in knee osteoarthritis (OA) patients METHODS: Fifty-one knee OA patients who fulfilled the ACR criteria were enrolled in this study. Knee ultrasonography was performed in affected knee joints with a 12 MHz linear probe to assess the presence of effusion, synovial proliferation, capsular distension, length of osteophytes, and thickness of cartilage. At the same time, the serum levels of hyaluronic acid (HA) and cartilage oligomeric protein (COMP) were measured by ELISA and serum osteocalcin levels were determined by RIA. RESULTS: The patients with longer medial osteophytes showed higher levels of serum HA and COMP than those with shorter ones. Serum HA levels were significantly higher in patients with larger amount of effusion and/or synovial proliferation, suggesting inflammatory changes within the joint, than those without. In addition, the severity of capsular distention was also correlated well with serum HA and COMP levels. However, the length of lateral osteophytes and thickness of femoral cartilage were not correlated with serum HA or COMP levels. Serum osteocalcin levels did not show any association with above ultrasonographic parameters, either. CONCLUSIONS: Using knee ultrasonography, we demonstrated that serum HA and COMP levels were elevated in more severe OA patients than less severe patients. This result suggests that detailed pathologic changes in the soft tissue and/or bone of OA joints on ultrasonography are being directly reflected to biochemical markers measured in the peripheral blood.

OBJECTIVE: To compare the incidence and clinical characteristics of tuberculosis (tbc) between patients with systemic lupus erythematosus (SLE) and kidney transplantation (KT) recipients. METHODS: Six hundreds and twenty-two patients who were diagnosed as SLE from 1990 to 2001 in Kang-Nam St. Mary's hospital were reviewed, retrospectively. As a control group, 347 kidney transplant recipients in the same center were evaluated. The extent of tbc was categorized into two groups: (1) limited disease (2) extensive disease. Cumulative steroid dosage and disease activity index including SLEDAI, serum complement levels, and anti-dsDNA titers were compared between the two groups. RESULTS: The cumulative incidence rate of tbc was similar in both groups (37 cases and 5.7% in SLE versus 17 cases and 4.9% in KT). Mean interval from SLE diagnosis or KT to tbc development was not different between the two groups. The most common site of tbc was lung/pleura, and the others included lymph nodes (2 cases), knee joint (1), bone marrow (1), central nervous system (1), kidney (1), colon (1), liver (1), and skin (1) in SLE. In contrast, most of tbc (16/17) developed exclusively in the lung and pleura in KT recipients. Cumulative doses of prednisolone 1 or 6 months before tbc diagnosis were not different between the two groups. Interestingly, extensive disease tended to be more frequent in SLE patients than in KT recipients although immuno-suppressants such as cyclosporine and azathioprine were more frequently administered in KT recipients. There were no differences in disease activity index including SLEDAI, complement levels, and anti-ds DNA titers at the time of tbc diagnosis as well as in the cumulative doses of steroid between extensive and limited diseases of tbc in SLE. CONCLUSION: The cumulative incidence rate of tbc was higher in SLE patients than in general population. The patterns of tbc tended to be more extensive in SLE compared to KT recipients in whom a stronger immuno-suppression was required, suggesting that immune dysfunction implicated by SLE itself may play an important role in determining the incidence and patterns of tbc infection.

PURPOSE: The incidence of childhood cancer in the Korea was studied to compare incidence rates between countries and between different regions in Korea. MATERIALS AND METHODS: A tatal of 2,891 cases, registered in the Natinal Cancer Registy from 1993 to 1995, were analysied. Death Certificate Only(DCO) cases were not included. DCO % was estimated about 22%. We calculated the incidence rates according to the International Classification of Childhood Cancer. The age-standardized rates by diagnostic group was compared with those of other countries. The total incidence of childhood cancer were compared among 34 cities in Korea with the rates in the rest of the nation. RESULTS: The crude incidence of all childhood cancer was 94.1 per million. The cumulative incidence to age 15 was 0.137% and the age-standardized rate, calculated using the world standard population, was 96.1 per million. In the incidence rates by diagnostic group, we observed many similarities with other countries in East Asia. The age-standardized rates of E, F and AL cities were significantly higher(p<0.05). In the 0-4 age group, F, AL and BB cities showed higher rates(p<0.05). In 5~9 years and 10~14 years, F city only had higher rates(p<0.05). CONCLUSION: Further study will be needed in order to investigate possible environmental factors which may account for the regional variations.

Although chemotherapy remains to be the mainstay of treatment of trophoblastic disease, hysterectomy has been performed as the primary management of nonmetastatic trophoblastic disease who desire sterilization and for uterine disease resistant to chemotherapy. Clinically, the documentation of disease regression is provided by serial quantitative serum beta-hCG assays and the persistent disease may be indicated when the serum beta-hCG values rise for 2 weeks or plateau for 3 weeks or more. Because of similarity in molecular structure, the confounding effect of an elevated LH on beta-hCG assessment in castrated women after treatment for trophoblastic disease has been documented. This LH cross-reactivity may be suspected in women with bilateral oophorectomy demonstrating persistent low levels of beta-hCG. It is particularly true when the assay is perfo-rmed by conventional polyclonal radioimmunoassay. We have experienced two cases of nonmetastatic trophoblastic disease whose serum beta-hCG assay plateaued at a low level after total abdominal hysterectomy with bilateral salpingo-oophorectomy and chemotherapy. Clinical and radiologic work-ups were done for metastatic lesion in dose patients, but the results were negative. The quantitative LH assays (Serono LH MAIAclone kit, Roma, Italy) were performed with the sera obtained from the patients; the results were 37 and 31 mIU/ml (1st IRP) with beta-hCG of 14 and 13 mIU/ml (1st IRP), respec-tively. With the initiation of oral estrogen replacement thrapy to those patients, the quantitative beta-hCG values fell below 5 mIU/ml (1st IRP) and they remained in complete chemical remission without any additional chemotherapy for one year. The persistant low titers of beta-hCG in those patients were considered to be result of LH cross-reactivity on beta-hCG assessment. It is concluded that whenever the assay of beta-hCG shows persistent low titers in the oophorectomized patient for treatment of trophoblastic disease, LH cross-reactivity should be suspected.
