To delineate the individual role of follicular dendritic cells (FDC) and T cells at each stage of GC B cell differentiation at the clonal level and to analyze the signals required for the differentiation, we developed an experimental model using an FDC line, HK and a lymphoma cell line, L3055 for centroblasts. Phenotypic analysis of L 3055 revealed its origin of GC and the homogeneity. L3055 cells undergo spontaneous apoptosis when cultured in the absence of HK cells. L3055 cells proliferate continuously in the presence of HK cells, while they differentiate into a population with the phenotype of centrocytes after stimulation with CD40 ligand (CD 40L) plus IL-2, IL-4 and IL-10. L3055 undergo anti-Ig-mediated apoptosis, which is not protected by HK but by CD40L and the cytokines. These experimental results suggest that FDC provide signals for the survival and rapid proliferation of centroblasts and T cells trigger the differentiation of centroblasts into centrocytes.

The nevua of Ota is a congenital pigmentary disorder of the skin and mucaus membrane, partieularly in the periorbital region, the temple, the forehead, the malar area and the nose. The nevus of Ita differs from the nevus of Ota in its distribution in the supraclavicular, scapular, and deltoid regions. It may occur alone or in association with ipsilateral or rarely with bilateral nevus of Ota. We present a 22 year-old female who has had pigmentary anomalies on the both malar areas and left sclera associated with pigmentation of the right shoulder.

As the incidence of dermographism in our urticaria clinie is quite high comparing data in other country, we have tried to survey the incidence of ermographism in the general population of Korea using a dermographic tester designed by other author. Total 8g7 healthy persons were included in this study from March J98$ to .December 1983. The study result was summarized as follows, 1. Male to female ratio was 2. 5: 1 and the peak age of the subjects was third(47 8%), fourth and fith decades in ecreasing order, The overall incidence of dermographisrn from the pressure of 48ppg/cm was 4.4% and there were no significa.nt difference in the incidences between male(4, 2%) and female(4 7%) (p>0. 1), and between the different age groups(p>0 l)

BACKGROUND: Many of the major life events that appear to affect biologic system and health occur within the context of the family and can have a profound psychosocial and biologic impact on family memebers. So, the present study attempted to examine the relations of family function with stressful life events, depression, and physical and psychological symptoms reported by patients. METHODS: Design : Cross sectional, observational study. Participants : 41 healthy adult males from a family medicine ambulatory care unit in a tertiary hospital located in Guro completed a series of psychometric instruments that include the Family APGAR(Adaptation, Partnership, Growth, Affection, and Resolve), FACESIII(Family Adaptability and Cohesion Evaluation Scale), Modified 46-item Stressful Life Events Scale, Lee's 98 items Stressful Life Event Scale, Korean version of BEPSI(Brief Encounter Psychosocial Instrument) and BDI(Beck's Depression Inventory Scale). RESULTS: Family APGAR was negatively correlated with stress related life events(both in total and negative events, -0.30, -0.37, respectively; p<0.05) and BEPSI(-0.56; p<0.0001). No significant correlation could be found between family function and positive life events. Family APGAR also revealed significant negative correlation with BDI(-0.61; p<0.0001). Among the three family types, severe dysfunctional family demonstrated highest level of stressful life events score, perceived stress, and depression(p<0.05). CONCLUSIONS: The higher the assessment of the family function(Family APGAR), the lower the level of stressful life events, perceived stress and depression. There, knowledge of the family function, stress, and coping could be useful to family physicians in the whole person approach of their patients.

BACKGROUND: Compliance with self-care and lifestyle modification is recommended for all patients with acute coronary syndrome to prevent a secondary attack. Data is limited regarding the association between compliance with self-care and restenosis. This study was conducted to examine the association between compliance with self-care and restenosis and to determine the predicting factors for restenosis and low compliance with self-care. METHODS: A total of 166 acute coronary syndrome patients (64.2+/-10.8 years) hospitalized for an angiogram during routine follow-up or symptom management were conveniently recruited from a university hospital cardiovascular care unit. Self-administered questionnaires were used to evaluate the level of compliance with self-care and symptom-related satisfaction. RESULTS: In-stent restenosis was found in 40.4% of the subjects and 36.1% were persistently smoking. There was no significant relationship between low compliance with self-care and restensosis. A lower symptom-related satisfaction significantly predicted restenosis and low compliance with self-care. A longer period after initial diagnosis predicted restenosis and a shorter period after initial diagnosis predicted low compliance with self-care. Persistent smoking was independently associated with low compliance with self-care. CONCLUSIONS: Patients who continued to smoke and had lower symptom-related satisfaction with daily living showed a stronger tendency for lower compliance with self-care and lifestyle modification. Effective educational strategy focusing on smoking cessation is needed to increase compliance with self-care in patients with ACS, especially during admission with a first heart attack.
