The formation of spontaneous rosettes between human lymphocytes and sheep erythro ytes under suitable conditions is a constant feature of T-lymphocytes. Recently. It has been demonstrated in the mouse, rat, guinea pig and in man that a certain proportion of peripheral blood lymphocytes has the property to bind autolognus erythrocytes in vitro. These lymphocytes are called auiologous rosette forming cells(ARFC). Although there are several reports on human ARFC. the results are not in accordance. The present study was undertaken to demonstrate the autologous rosette forming property of human peripheral blood lymphocytes, and to enumerate the percentage of ARFC in different sex and age guoups. Fifty healthy persons entered this study between Martch and September. 1980. at the Department of Dermatolgy, Seoul National Universty Hospital. The method of quantitation of AREC was s sight modification of that of Lambermont et al(1977). The results were as follows.

Pigmented contact dermatitis, firstly reported by Dr. Osmudsen in 1970, is a disease result from recurrent contact dermatitis due to hypersensitivity to cosmetic companents, which produces secondary bizarre dark brown hyperpigmentation. Histological examination of this condition reveals liquefaction degeneration of the basal cells of the epidermis and melanophages in the upper dermis. However, this entity has not been reported in the Korean literature until now. We report three cases of pigmented contact dermatitis which were diagnosed by the histological examinations and the patch tests.

PURPOSE: The purpose of this study is to provide base data for preparing plans that North Korean (NK) Refugees can adjust themselves to our society with a healthy mind after they get over their health problems using the Health Belief Model, knowing the relationship between individual characteristics and health beliefs, and health behavior. METHODS: The subjects were 304 NK adult refugees in Hanawon. Data were collected by demographic questionnaire, health behavior scale, self-efficacy scale, perceived benefit scale, perceived barrier scale, perceived seriousness, perceived sensibility, and individual characteristics. RESULTS: The factors influencing the health behavior of NK refugees were perceived benefits, self-efficacy, the period in the third country and experience in being expelled to NK, and these variables were describing 31.4% of the health behaviors of refugees. CONCLUSION: The perceived benefits and self-efficacy of health belief and specific experiences related to refugee affected NK refugees' health behavior.

Achondrogenesis type 2 is a lethal form of congenital skeletal dysplasia characterized by severe short-limbed dwarfism, decreased vertebral ossification and normal ossification of the skull. We report an autopsy case of achondrogenesis type 2 in a female fetus terminated at 29 weeks of gestation. External morphology revealed a relatively large head, short upper and lower extremities, short neck, and distended abdomen. The x-ray finding showed normal calvarial ossification, hypoplastic ilium and unossified ischium, and metaphyseal flares of the femur and tibia. Histologically, chondrocytes were large and irregular with increased vascularity.

Clear cell meningioma is a recently recognized morphologically unique entity. It shows no sex predilection, affects primarily the lumbar region, and the cerebellopontine angle. Despite its benign appearance, it may be aggressive, particularly in intracranial cases. All lesions are moderately cellular, with the exception of stromal hyalinization. The tumor consists largely of a sheet- like or somewhat lobular pattern of polygonal cells, the cytoplasm of which is clear. No close association is noted between the recurrence or the clinical outcome and factors such as mitotic activity, the PCNA index, and the DNA ploidy status. But the MIB-1 proliferation index is appreciably higher in recurrent tumors. We experienced a case of clear-cell meningioma showing a characteristic histologic finding. A 39-year-old man was admitted due to the recent onset of right-sided, facial-nerve palsy, left hemiparesis and general weakness. A CT scan of the head showed a well defined mass in the petroclival area. After surgical resection, the patient was in good condition, but 1 year later symptoms recurred. A CT scan of the head showed a huge, recurrent petroclival tumor with adhesion to the surrounding brain parenchyme.

Gastrointestinal angiodysplasia is a distinct disease entity which causes frequent gastrointestinal bleeding. It predominantly arises at the stomach and duodenum in the upper gastrointestinal tract and cecum and ascending colon in the lower gastrointestinal tract. The general histological finding of the angiodysplasia is a submucosal vascular ectasia and tortuosity. We have experienced two cases of the intestinal angiodysplasia. The first case occurred on a jejunum in a 22-year-old woman who had anemia. The second case occurred on a sigmoid colon in a 59-year-old man who had constipation. In addition to the general histologic finding of the angiodysplasia, the microscopic findings of the first case revealed some capillary hemangioma-like areas; and in the second case, there was a marked ischemic change and the thickening of the wall.
