Nitric oxide(NO) is a labile, uncharged, reactive radical that functions as a sensitive mediator of intercellular communication in diverse tissues. It has been reported that NO is produced by osteoblast and these results may suggest that NO is integrally involved in the regulation of osteoclast formation and osteoclast resorption activity by osteoblastic cells. We examined the effect of cytokines on NO release by mouse bone marrow cell. We also examined the effects of cytokokines and sodium nitroprusside(SNP) on the formation of osteoclast-like cell from mouse bone marrow cells in culture. Cytokines stimulated NO production of mouse bone marrow cells, and N-nitro-L-arginine methyl ester, a specific inhibitor of NO synthase, suppressed the cytokine-induced NO production. SNP showed dual action in the generation of osteoclasts. The addition of 30μM SNP inhibited the formation of tartrate resistant acid phosphatase(TRAP)(+) multinucleated cell, whereas lower concentration(3μM) of SNP enhanced it. Althogh the precise action of NO remains to be elucidated in detail, the action of NO in osteoclast generation in our studies seems to be associated, at least in part, with bone matabolism and bone pathophysiology.

Propylenebis(isonitrosoacetylacetone imine)을 리간드로 하는 니켈(Ⅱ) 및 팔라듐(Ⅱ)착물의 합성 및 구조

Novel nickel(Ⅱ) and palladium(Ⅱ) complexes, Ni(IAA)_2-pn PdCl(IAA)-pn, where (IAA)_2-pn and (IAA)-pn represent N,N'-propylenebis(isonitroacetylacetone imine) and N-(2-aminopropyl)isonitrosoacetylacetone imine respectively, have been prepared. The nickel(Ⅱ) and palladium(Ⅱ) complexes were characterized on the bases of elemental analysis, IR, NMR, and electronic spectra. The reaction of nickel(Ⅱ) and isonitrosoacetylacetone(H-IAA) with propylenediamine gives an (IAA)_2-en type complex, while similar recation using palladium(Ⅱ) instead of nickel(Ⅱ) gives an (IAA)-pn type complex.

A survey to determine the copper content of early infant food sources was conducted. Collected samples from various lots were human milk from volunteer mothers and infant formula and market milk from markets. The determined results by atomic absorption spectrophotometer were as follows : 1.Averages of Cu were 34.26±13.89 μg/dl in human milk, 192.2±124.2 μg/dl in infant formula, 4.35±2.37 μg/dl in market milk and showed the decline trend by the lactation periods in human milk. (p<0.01) 2.Estimated daily intake of Cu from human milk was higher than that from infant formula in 3 months old infants.

This paper presents a system for tracking facial muscle movement from sequences of monocular MPEC images obtained from CCD camera. Circular fluorescent target is used as marker attached to the facial characteristic points. Initial locations of the targets are digitized manually for localization of its searching areas, and a template matching algorithm is employed to track the successive facial points. The obtained data are encoded to the special file format used in the Softimage which is an world-wide graphic package system. The proposed system serves to a graphic work for cyber actor in virtual space.

The superficial spreading type of early gastric cancer has usually been defined as an early gastric cancer in which the product of the longest diameter and the diameter perpendicular to it was greater than 25㎠. Although the superficial spreading type of early gastric cancer is histologically aggressive compared with those without such histological aggressiveness, the 5 year survival rate is as good as a non-superficial spreading types of early gastric cancers if the wide surgical resection with extensive lymph node dissection is performed as a treatment. We experienced a case of superficial spreading early gastric cancer in a 59-year-old man. This case is reported with a brief review of related literature.

The main purpose of this study is to identify and evaluate the depressive states for the patients with chronic pulmonary tuberculosis. A questionnaire(Self-rating Depression Scale, SDS) survey was performed toward 57 pulmonary tuberculosis patients with initial treatment who started chemotherapy and 53 pulmonary tuberculosis patients with retreatment, admitted to one tuberculosis-centered hospital and two general hospital. Fifty three healthy persons as control group were investigated with the same questionnaire for comparison. The survey was performed from July to August 1996. The results are as follws : 1. The patients had significantly high scores in the depression than control and the patient with retreatment showed significantly high scores in the depression than the patient with initia1treatment(P<0.01). 2. The depressive levels of the patients were associated with duration of admission and the expectancy of recovery (P<0.05). 3. The percentage of the subjects with 40 or more scores tentatively classifiable as psychologically depressed was 67.1% of the total subjects, 48.4% of the control groups, 75.0% of the patient with initial treatment and 84.1% of the patient with retreatment. Because patient with pulmonary tuberculosis with initial treatment showed higher depression scores than normal persons, and patients with retreatment due to failure of initial treatment showed higher depression scores than initial treatment, it is necessary to give attention to depression of the patients during treatment of pulmonary tuberculosis.

연구배경 : 정신분열병 환자들은 인지장애를 보이는바, 저자들은 이들을 대상으로 한국형 인지분화훈련 프로그램을 개발하여 정신분열병 환자들을 대상으로 인지재활훈련을 실시한 후 환자들의 인지기능, 정신병리 및 문제해결기술에 미치는 효과를 조사하였다. 방 법 : 28명의 정신분열병 환자를 훈련군(n=14)과 대조군(n=14)으로 나누어 훈련군에게 한국형 인지분화훈련 프로그램을 1회 60분씩, 주당 2회씩, 11주간 총 22회를 실시하였다. 환자들의 인지기능은 K-WAIS의 산수, 빠진곳찾기, 어휘, 공통점찾기 소검사로 측정하였고 정신병리는 양성 및 음성증상 척도로 측정하였으며 문제해결기술은 사회문제해결척도로 평가하였다. 인지재활훈련의 효과를 평가하기 위해 훈련 전후의 인지기능, 정신병리 및 문제해결기술의 변화를 종속변수로 하고 훈련 유무를 독립변수로 하여 반복측정에 의한 변량분석으로 자료를 분석하였다. 결 과 : 한국형 인지분화훈련이 시간에 따른 인지기능검사 중 산수 소검사, 문제해결기술 중 시회문제해결척도의 전체 점수와 문제해결기술 소척도의 점수의 변화에 유의한 영향을 미쳤으나, 시각적 주의력, 개념화 능력 및 정신병리의 점수의 변화에 유의한 영향을 미치지 않았다. 결 론 : 한국형 인지분화훈련 프로그램은 정신분열병 환자에서 청각적 주의력 및 문제해결기술의 호전을 꾀할 가능성이 있음을 시사한다. Objectives : The purpose of this study was to investigate the effects of cognitive differentiation training program- Korean version(a training program of attention and conceptual abilities) on cognitive function, psychopathology and problem solving skills in patients with schizophrenia. Methods : A total of patients diagnosed as schizophrenia using DSM-Ⅳ were randomly assigned to 2 groups. The training group went through a total of 22 sessions of cognitive differentiation training(60 min/ session×2 sessions/wk×11 wks). The attention-placebo control group received psychoeducation program during the same period. Arithmetic, vocabulary, similarities, picture completion of Wechsler Adult Intelligence Scale-Korean version, Positive and Negative Syndrome Scale, and Social Problem Solving Scales were administered to all patients, both before and after the training program. Results : In the arithmetic scores(F=6.35, af=1, p=0.018) of Wechsler Adult Intelligence Scale-Korean version, and total scores(F=6.35, af=1, p=0.018) and problem solving skill scale scores(F=4.88, af=1, p=0.036) of social problem solving scale, interaction effects of training was significant. Conclusion : Our findings suggest that cognitive differentiation training program-Korean version is effective on improving auditory attention and problem solving skills in patients with schizophrenia.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.
