Primary cutaneous CD3O(Ki-1) Positive anaplastic large cell Iymphoma(ALCL) is a rare subset of cutaneous Iymphoma. with a much better prognosis. ALCL is a heterogeneous process that may have a T-cell, B-cell, or indeterminant(null) phenotype and which may or may not express the anaplastic Iymphoma kinase(ALK) oncoprotein. We report a case of ALCL in a 72 year old man. About 4 months ago, multiple erythematous firm ulcerative mass and satellite nodules developed on the right lower leg. The skin lesions rapidly increased in number and size. Some lesions became painful and centrally ulcered. The histologic findings showed a diffuse infiltrate of large Iymphocytes with large nuclei, prominent and multiple nucleoli, and ample cytoplasm. Immunohistochemical stainings for CD3O, CD5 were positive but stainings for LCA, CD3, CD45RO, CD2O, cytokeratin, EMA, and ALK were negative. Therefore, we diagnosed our case as CD+/30ALK- ALCL (Korean J Dermatol 2003;41(5) : 666~669)

Widespread use of BCG has not controlled tuberculosis, and more effective vaccines are clearly needed. Although chemotherapy will remain the mainstay of antituberculosis treatment, the use of adjunctive immunotherapeutic modalitites is attractive, particularly in persons with drug-resistant tuberculosis. Administration of IL-2 or IFN-γto tuberculosis patients enhance bacillary elimination. Cell-mediated immunity is the critical protective immune response in tuberculosis. Mycobacterial antigens are recognized by T cells and that elicit production of protective cytokines are potentially important vaccine antigens. The 30 kDa antigen is secreted in large quantities by growing mycobacteria. That antigen elicits greater proliferation in lymphocytes from healthy tuberculin reactors than healthy tuberculin nonreactors. In this study, the T lymphocyte proliferative responses to 30 kDa antigen from Mycobactrium tuberculosis H37Rv were examined by using tonsilar and peripheral blood lymphocytes from PPD(+) and PPD(-) tonsilectomized persons. When cultured with 30 kD antigen, tonsilar mononuclear leukocytes and T cells of PPD(+) demonstrated more ^3H-thymidine incorporation than PPD(-) persons (stimulation index was 2.5 and 1.9, 0.8 and 1.0, repectively). Peripheral blood mononuclear cells (PBMC) and peripheral blood T lymphocytes were shown the similar responses to this antigen. The combination of IL-2 and 30 kDa antigen elicited a significant proliferative responsiveness in tonsilar mononuclear leukocytes and T cells of PPD(+) persons (SI was 20 and 14.1). PBMC and peripheral blood T cells of PPD(+) persons were also shown a significant responsiveness, but PPD(-) persons did not show. These results demonstrate that the 30 kDa antigen and IL-2 have a synergistic stimulatory property in mycobacteria sensitizing lymphocytes.

Objectives The Mental Health Act is an initiative aimed at changing and shaping mental health services and protecting human rights of persons with mental disorders. Since the Mental Health Act was legislated in 1995, four amendments have been made according to the issues that arose from public concerns. However, there are still many debates about the human rights protection of the mentally iII. This study aimed to provide information regarding major aspects of the Mental Health Act by comparing them among several developed countries. Methods Current Mental Health Acts of the state of Michigan in the United States, Scotland in England, the state of Victoria in Australia, and Japan were reviewed. Issues regarding the Korean Mental Health Act were collected from seminar materials, news media contents, and mental health professionals Results The definition of subjects in Korean Mental Health Act was more inclusive than other countries and was derived from a medical classification of mental illness. Family members or guardians were granted important responsibilities for deciding the involuntary admission of mentally ill patients in Korea and Japan. In Western countries, Mental Health Review Tribunals or courts have the primary responsibility for important decisions about mentally ill patients. The regulation of immediate dis- charge after request by voluntarily admitted patients was not enacted in all countries except Korea. The mandatory procedure for involuntary admission in Western countries includes an individual case review with personal interview by a Mental Health Review Tribunal or court. Conclusion The Korean Mental Health Act appears to meet the basic standards of Guidelines from international organizations. Our traditional culture and inherent health systems seem to influence the legal regulation of mental health service and might be related to the problems of human rights protection of mentally ill patients in Korea.

대부분의 실제구조물은 인장과 진동 등이 동시에 작용하는 복합하중 상태가 되며 이러한 환경에서 물체의 거동을 해석하는 것이 중요하다. 이 논문에서는 χ축에 대해 45˚결함이 있는 평판이 하중을 받고 있을 때, 진동 특성을 시간평균 electro speckle pattern interferometry(ESPI)를 이용하여 해석하였다. 결함이 있는 박판 시험편에 인장력을 증가하면서 물체의 고유진동수 변화와 모드의 형태 변화를 동시에 관찰하였다. 실험결과에서 결함은 저차모드에서는 진동모드에 영향을 주지 않았으나, 고차모드에서는 진동모드에 변화를 주었으며, 특정 진동모드에서 결함의 영향으로 현저하게 고유주파수가 낮아지는 경향을 보였다. 또한 실험결과는 유한요소해석과 비교하여 주파수 비교에서는 5%이내의 오차율을 보였으며, 진동모드 비교에서는 완전히 일치하였다. This paper presents the vibration characteristics of a rectangular plate with 45˚ oblique crack subjected to a uniaxial tension. The experiment is adopted by the time-average Electronic Speckle Pattern Interferometry(ESPI) method. The natural frequency and mode shape are considered accurately according to the increase of tensile load. When tensile load is zero, the vibration modes are agreed with the smooth and the 45˚ obliquely cracked plate. But according to the increasement of load, it is shown that vibration modes are extremely varied. The effects of the crack under the vibration are discussed in detail. It is indicated that the increase of load makes the variation of the frequencies and modes complicate in the range of even a small load. The results are agreed with the FEM analysis within 5%.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is characterized by symmetrical weakness, impaired sensation, absent or diminished tendon reflexes, an elevated cerebrospinal fluid protein level and nerve-conduction studies that show demyelination. The occurrence of CIDP in patients with systemic lupus erythematosus (SLE) has been rarely reported. We experienced a case of a 33 year-old woman with SLE and she presented with fever, abdominal pain, a tingling sensation of both of her hands and feet, and symmetrical weakness in both the proximal and distal extremities. Her symptoms had persisted for over 1 months before she visited our department. The CSF examination showed an elevated protein level and the nerve conduction studies revealed demyelination. Her symptoms showed minimal improvement with high dose steroid and immunoglobulin therapy, but she responded to cyclophosphamide therapy.

Molecular Characterization of Phytocystatins Isolated from Chinese Cabbage Flower Buds

Joon Ki Hong,Jung Eun Hwang,Chan Ju Lim,Kyun Oh Lee,Woo Sik Chung,Beom Seok Park,Chae Oh Lim 한국유전학회 2008 Genes & Genomics Vol.30 No.3

Chinese cabbage cDNA clones ( BCPI-1, -2, and -3) encoding phytocystatin were characterized. The deduced BCPI amino acid sequences contained the consensus motifs that have been shown to interact with the active site of cysteine peptidases (CysPs). BCPI-1 and -2, but not BCPI-3, contained an extended carboxyl-terminal region that included a cysteine residue. BCPI-1 and -2 existed both as monomers and dimers. The monomeric forms of BCPI-1 ( Ki =6.84 ± 0.3×10(-8) M) and BCPI-2 ( Ki =6.77 ± 0.2×10(-8)M) inhibited papain equimolar complexes in competition with their substrates. The inhibitory activity was clearly reduced in the pH range of 7.0-11.5. In contrast, BCPI-3 was present only as a 16 kDa monomer, and had a Ki value of 6.14 ± 4 × 10(-8) M against papain. It was highly stable over wide ranges of pH values and temperature. The differences between the BCPIs with respect to protein stability and inhibitory activity suggest that they may play diverse physiological roles in Chinese cabbage, and may interact with cysteine peptidases through different conditions.
