PURPOSE: It is well known that use of intranenous methylprednisolone(IVMP)for the patients with idiopathic thrombocytopenic purpura(ITP) is not only as effective as use of intravenous gammaglobulin to mincrease platelets quickly, but also the former is less expensive than the latter. As the adequate dosage of IVMP has not been fully elucidated, we have tried to determine it. METHODS: The subjects were 35 childhood patients below 15 years of age, who were diagnosed with ITP for the first time and whose platelet count was less than 20,000/mm(3) at diagnosis. We divided them into three groups : Group A included 8 cases with IVMP dosage of 5mg/kg/day, Group B included 9 patients with IVMP dosage of 10mg/kg/day, and group C included 18 patients with IVMP dosage of 20mg/kg/day. We checked the platelet count every day after IVMP administration daily for 5 days and also observed for side effects if any. RESULTS: After IVMP administration, we obseved increasing tendency of platelets in all three groups, of which group C was more rapid and higher in increasing platelets than the other groups(p<0.05). After IVMP therapy for 5 days, cases with platelets>20,000/mm(3) were 6(75%) in group A, 7(78%) in group B, and 18(100%) in group C. Cases with platelets >50,000/mm(3) were 5(63%), 6(67%), 17(94%) in groups A, B, C, respectively, and cases with platelets> 100,000/mm(3) were 3(38%), 5(56%), 14(78%), in group A, B, C, respectively. And there were no remarkable side effects except a case of transient hypertensive headache in group C. CONCLUSIONS: We concluded that the effectiveness of IVMP therapy for increasing platelets was more rapid and higher in group C than in group A or B, and side effect was minimal.

Purpose: This study examined the effects of a physical stability exercise program on the functional movement and balance of middle school volleyball players to provide future management and training data to improve the performance of volleyball players. Methods: The subjects were 20 volleyball players from Y Middle School in Mokpo. The results of comparing and analyzing the effects of the physical stability exercise program on the functional movement and balance of middle school volleyball players for 10 weeks are as follows. Results: The number of participants who showed power and agility (p<0.01) was increased significantly, and the response time was shortened significantly (p<0.01). On the evaluation of functional movement, the total score showed a significant difference between the pre-test at 10.90±1.30 points and the post-test at 13.81±.60 (p<0.001). The subjects’ balance showed a significant difference from 84.11±7.53 to 97.65±8.47 (p<0.001), and the Right Composite Score showed a significant difference from 83.74±6.64 to 97.27±8.48 (p<0.001). Conclusion The application of a physical stability exercise program for 10 weeks is effective in improving the speed, agility, functional movement, and balance to volleyball players who are weakened and at risk of injury. This is believed to prevent or reduce injury.

Clear cell sarcoma of the kidney(CCSK) is one of the rare malignant renal tumors in childhood and is different from Wilms tumor by its pathologic features, clinical manifestations and propensity to metastasize to the skeletal system and brain. We report a case of CCSK on the right kidney in a 14-month-old girl presented with abdominal distention and palpable huge abdominal mass on physical examination, followed by metastasis to the rib on the left upper thorax. After right nephrectomy, chemotherapy with National Wilms Tumor Study DD regimen(vincristine+dactinomycin+adriamycin) was continued without any evidence of relapse until the last follow-up, 1 year after beginning chemotherapy. A brief review of related literatures was made.

PURPOSE: Rib fractures are the most common injuries resulting from blunt chest trauma. The sensitivity of conventional chest radiography (chest PA, rib series) in showing a rib fracture is limited, particularly in those involving the cartilage part of the rib. We investigated the possible rib fractures. We used ultrasonography (US) to investigate possible rib fractures in patients with minor blunt chest trauma who showed no evidence of a rib fracture on the conventional chest radiography. METHODS: A total of 96 patients with minor blunt chest trauma and showing no evidence of a rib fracture on the conventional chest radiography were examined with US performed with a 7.5-MHz linear transducer. RESULTS: A total of 44(45.8%) patients showed a rib fracture whereas 52(54.2%) patients had no evidence of a rib fracture. Fracture of the rib with displacement 24 patients was the most common finding. CONCLUSIONS: Rib US is a useful imaging method in showing rib fractures overlooked on chest X-rays in cases of minor blunt chest trauma. Compared with conventional chest radiography, rib US takes a shorter time and is not difficult. Additionally, lesions combined with rib fractures and costal cartilage fractures are diagnosed more easily when using rib US.

Actinobacillus actinomycetemcomitans, a gram-negative, capnophiTic bacterium, is associated with several human diseases including periodontal disease. Products of A. actinomycetemcomitans exert immunomodulatory effects on various lymphoid populations, some of which may be implicated in the pathogenesis of periodontitis. It has been recently suggested that some of periodontopathic bacterial products might possess superantigenic (SAg) activities. In order to examine SAg activity of A. actinomycetemcomitans, we tried to purify immunomodulating factor (IMF) which can induce proliferation of mouse splenocytes and human PBMC. IMF fraction was obtained from the culture supernatant of A. actinomycetemcomitans by alcohol precipitation, ultrafiltration, size exclusion chromatography, and dye ligand affinity chromatography which has been widely used for the puri5cation of known SAgs. SDS-PAGE analysis showed that the factor migrated to a molecular mass of 40 kDa. The concentration of IMF which elicited maximal proliferative response of mouse splenocytes was ranged 1-10 ug/ml of protein on day 3 in culture. Human PBMC gave a similar response profile to IMF, but their maximal response was obtained by lower concentraion of IMF on day 2 in culture. This activity of IMF was heat and proteinase K sensitive and was not blocked by co-incubation with polymyxin B, a ligand for the lipid A region of lipopolysaccharide. T cell-enriched fraction of mouse splenocytes obtained by nylon wool column lost the response to IMF. Even though mitomycin C-treated antigen presenting cells were added to T cell-enriched fraction, the response to IMF was feeble as compared to unfractionated cells. Splenocytes depleted of T cells by anti-Thy 1.2 and complement also did not respond to IMF. These findings demonstrated that T cells are responsible for a minor proportion of the observed proliferation induced by IMF and the help of these cells are essential to the most of the proliferating cells which may be B cells. This observation was confirmed by flow cytometric analysis of responding lymphocyte subpopulations. These results indicate that IMF of A. actinomycetemcomitans does not act in a manner consistent with known SAgs but is more relevant to the explanation of pathologic findings of periodontal lesions.
