Idiopathic thrombocytopenic purpura(ITP) is an autoimmune bleeding disorder characterized by the development of antibodies to one's own platelets, which are then destroyed by phagocytosis in the spleen and liver. Its clinical manifestations are characterized by bleeding and the most serious complication is hemorrhage into the central nervous system, but which is rarely seen below 1%. In treating IPT, the therapy of first chice is administration of adrenocorticosteroid and r-globuline. If satisfactory results are not obtained, then splenectomy is recommended. If this also proves inadequate, then administration of immunosuppressants is carried out. 16-year-old male was admitted with complaints of left hemiplegia and nasal bleeding. This case may be developed spontaneous intracerebral hemorrhage causing thrombocytopenia and was treated by steroid, r-globuline and splenectomy, but satisfactory results are not obtained. After all, the paient was successfully treated with cyclophosphamide.

Platinum catalysts supported on carbon were prepared by using various method. The particle size distribution of loaded platinum was examined using transmission electron microscope, and that was discussed relatively to the oxidation treatment of carbon black and loading method of platinum. In addition, the relationship between its particle size distribution and catalytic activities in the deep oxidation reaction of carbon monoxide and the reduction removal of dissolved oxygen by hydrazine. The number of functional groups on carbon black largely increased by the oxidation treatment with nitric acid compared to that with air or hydrogen peroxide. The large number of functional groups were effective for homogeneous loading of platium, dispersing highly homogeneous platinum particles of 2∼3 nm in a diameter by the methanol reduction method. On the other hand, a large amount of platinum could be loaded on carbon balck using an impregnation method, but the particle size distribution of platinum was poor in homogeneity. Platinum could be dispersed with extremely small particles using on ion exchange method, but the loading amount of platinum was very small. The activities of Pt/VX catalysts in the oxidation reaction of carbon monoxide and the redution of dissolved oxygen strongly varied with the number of platinum atoms exposed, regardless of the particle size, indicating that the highest catalytic activity was obtained on the Pt/VX catalyst prepared using the methanol reduction method due to the high dispersion and large loading of platinum.

목적 : Vancomycin 내성장구균(VRE)은 병원감염의 중요한 원인균으로 VRE 보균상태의 환자들을 파악하여 감염을 예방할 수 있는 감시체계가 필요하다. 본 연구에서는 혈액종양병동 입원 환자를 대상으로 VRE의 직장내 감시배양을 실시하여 그 빈도 및 분포를 알아보고, 집락화된 균주와 임상검체에서 분리된 VRE와의 관계를 알아보고자 하였다. 방법 : 가톨릭대학교 성모병원 혈액종양병동에 입원해 있는 환자를 대상으로 14개월간 직장 감시배양을 시행하였다. 혈액한천배지에서 장구균이 의심되는 집락을 따서 vancomycin 6㎍/㎖이 포함된 Brain-heart infusion agar에 10^(6) CFU를 접종하여 vancomycin 내성선별검사를 하였다. 이 기간 동안 4병실에서 환경감시배양을 시행하였다. 분리된 균주는 Microscan을 이용하여 균종을 동정하였고 vancomycin에 대한 최소억제농도를 측정하였다. Multiplex PCR로 균종 확인 및 동시에 vancomycin 내성 유전형을 알아보았다. 결과 : 대상이 된 452명의 환자 중 230명(50.9%)이 직장내 VRE 보균자로 확인되었다. 균종의 분포는 E. faecium (72.4%), E. faecalis(24.1%) 순으로 vancomycin에 대한 MIC가 128㎍/㎖ 이상의 고도 내성이었으며, vanA형이 대부분이었다. 환경 감시배양에서는 2개 병실에서 VRE 4주가 분리되었다(E. faecium 3주, E. faecalis 1주). 감시기간동안 32명의 환자의 임상검체에서 33주의 VRE가 동정되었고 이 중 29명(90.6%)이 직장내 VRE 보균자였다. 결론: 가톨릭의대 성모병원 혈액종양병동의 VRE의 직장 내 집락화율이 높음을 알 수 있었다. 특히 임상검체에서 VRE가 분리된 환자의 경우 VRE 직장내 집락화율이 유의하게 높게 나타나 보균상태의 VRE가 환자의 감염에 직접적인 연관이 있을 수 있으므로 이를 예방하고 관리하는 지침이 필요하다고 생각한다. Background: Vancomycin-resistant enterococci (VRE) have emerged as important pathogens among hospitalized patients. We evaluated the prevalence of rectal VRE colonization at hematology-on-cology unit and the correlation between VRE colonization and infection. Materials & Methods: All VRE isolates were obtained from rectal swabs and clinical samples of the patients hospitalized over 14-month period at hematology-oncology unit in St. Mary's Hospital. The agar screening test was performed by using 6 ug/ml of vancomycin in brain heart infusion agar with 10^(6) CFU inoculum. During this period, the environmental surveillance culture was performed in 4 hospital rooms. Species identification of VRE was done by Microscan and MICs to vancomycin. Identification and genotyping of VRE pattern were confirmed by multiplex PCR. Results: Rectal colonization rate was 50.9% (230 among 452 patients). The most common isolate was E. faecium (72.4%) followed by E. faecalis (24.1%), and all had vanA genotype. Four VREs (three E. faecium and one E. faecalis) were isolated from 2 hospital rooms. During this period, 33 clinical VRE strains from 32 patients were isolated (infected or colonized). Twenty nine (90.6%) of these clinical isolates came from VRE carriers. Conclusion: This study showed a high rectal colonization rate of VRE in patients hospitalized at the hematology-oncology unit in St. Mary's Hospital. The colonization rate of VRE in the rectum was higher among the patients who had clinical infection by VRE. Therefore, the strategies for prevention and control of VRE infection should be deveoloped and monitored.

To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

The purposes of this study were to investigate the physicochemical characteristics and storage stabilities of various sauces with added Yuza(Citrus Junos). Yuza consisted of three parts: peeled (46.17%), fleshed (43.74%) and seeded (10.09%). Yuza juice revealed 11.33% extraction yield, pH 2.85, 4.18% total acidity, 11° Brix, 1.16% transmittance and 2.63° Brix/acid ratio. Five kinds of sauces with added Yuza juice were Yuza red pepper paste sauce, Yuza soybean sauce for meat, Shahu shabu Yuza sauce, Korean Yuza vegetable sauce and Japanese Yuza soybean sauce. These sauces showed slight changes in pH, total acidity, total bacterial counts and overall sensory characteristics during storage period (60 days). In conclusion, Yuza juice could be applied to various sauces, which remained usable for 60 days.
