Fine needle aspiration of the breast is an important diagnostic tool in malignant lesions, but is also useful in differentiation of inflammatory breast diseases mimicking carcinoma clinically and radiologically. Recently, the authors have experienced eight biopsy-proven cases of chronic inflammatory diseases of the breast, which consisted of 4 cases of duct ectasia, 2 cases of fat necrosis, and a case of tuberculous mastitis and granulomatous mastitis respectively, Their cytoiogic features mainly based on the components and the relative frequency of inflammatory cells were evaluated for differential diagnosis of chronic inflammatory breast diseases. The results are as follows ; 1. In cases of duct ectasia, varying amount of neutrophils, mononuclear leukocytes, histiocytes and multinucleated giant cells were intermixed with benign epithelial cell clusters. 2, Abundant fat tissue fragments were diagnostic for fat necrosis. Histiocytes and mononuclear cells were main components but not rich, and neutrophils and giant cells were infrequently observed. 3. Characteristic granulomas composed of epithelioid cells, mononuclear leukocytes and Langhans' type giant cells and lymphocytic infiltrates were conspicuous in tuberculous mastitis, and occasionally neutrophils, necrotic materials and epithelial cell clusters were found. 4. In granulomatous mastitis, epithelioid cell granulomas were also noted but numerous neutrophils and histiocytes were intermingled within or outside the granulomas.

In a six-year period(1988. 5-1994. 4), fine needle aspiration cytology(FNAC) of 322 pulmonary lesions from 296 patients were performed at Soonchunhyang University Hospital. Of these 322, malignancy was diagnosed cytologically in 139(43.2%), suspicious malignancy in 7(2.2%), negative in 164(50.8%), and insufficient material in 12(3.8%). Malignant lesions consisted of 54 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 18 cases of small cell carcinoma. They were verified by histologic examination in 70 cases. There were 2(0.6%) false positive cases due to florid bronchoalveolar hyperplasia and atypical bronchial epithelial cells associated with granulomatous lesion. The overall accuracy rate was 90%, the sensitivity 84.3% and the specificity 94.7%.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.

BACKGROUND: The present study is undertaken to acquire normative data of health-related physical fitness(HRPF) of Republic of Korea Air Force(ROKAF) aircrews and to provide norm-referenced standard of HRPF. METHODS: From 15 May 1998 through 14 December 1999, 1284 KAF pilots are checked muscular strength, muscular endurance, flexibility, and body fat percentage. RESULTS: The grip strength was relatively maintained, but flexibility, back strength, and muscular endurance were declined according to promotion and aging. And the incidence of obesity determined by bioelectrical impedence analysis was higher than that assessed on the basis of height and weight. CONCLUSION: It is suggested that many pilots who were normal in BMI have abdominal or visceral obesity. Further studies must be made on the health promotion program for the pilots, on the changes in physical fitness, and on the criterion-referenced standard of HRPF of the pilots.

Purpose: The purpose of this study was to investigate the effects of the scapulothoracic mobilization on subject with lateral epicondylalgia. This was done through lateral slide scapular test, grip strength, visual analogue scale, glenohumeral joint external rotation range of motion. Methods: Before the experiment, Lateral slide scapular test, grip strength, visual analogue scale, glenohumeral joint external rotation range of motion were measured. Scapulothoracic joint mobilization was applied and then measurements were taken again to compared the changes. Results: After applying the scapulothoracic joint mobilization, lateral slide scapular test, grip strength, visual analogue scale, glenohumeral joint external rotation range of motion significantly improved. Conclusion This study found that the scapulothoracic mobilization was effective in improving functional aspects and pain on subject with lateral epicondylalgia. The results suggest that the scapulothoracic joint mobilization is a significant considered intervention method that could be used for subject with lateral epicondylalgia.

The treatment strategy for children with attention deficit/hyperactivity disorder (ADHD) mainly involves medication, although research on non-pharmaceutical treatments steadily continues. Neurofeedback is considered as a nonpharmacological treatment strategy for children with ADHD. In this review, the concept and principles of neurofeedback, the electroencephalography characteristics of children with ADHD, and the background for application of neurofeedback therapy in these subjects are described. The results of the latest studies are presented, showing that neurofeedback treatment seems to be effective in improving some symptoms, and that it can be useful as a complementary treatment. However, further research is needed to investigate whether neurofeedback alone may be as effective as drug treatments.

The diagnosis of carcinoma in situ of urinary bladder is difficult in that the symptoms and cystoscopic findings are nonspecific. The cytology of urine could be helpful for diagnosis of carcinoma in situ of urinary bladder. We present a case of bladder washing cytology of carcinoma in situ. A 54-year-old man presented with dysuria for 1 year. Cystoscopic findings revealed multifocal reddish trabeculated lesions. The bladder washing cytology revealed rather uniform tumor cells which were singly scattered or forming syncytium in the clean background. The nuclei were round to oval with inconspicious nucleoli. The cystoscopic biopsy revealed typical histologic features of carcinoma in situ of urinary bladder.

PURPOSE: This study investigated the relationship between height and psychopathology in community children with relatively short stature according to the parents' reports. Also, the matter of parental concern about child's height was explored. METHODS: The child behavior checklist (CBCL), the Brief Encounter Psychosocial Instrument (BEPSI), and the child-health questionnaire-parent form 50 (CHQ-PF50) were administered to 423 parents (from elementary and middle school children's) in Gangnam, South Korea. Subjects were divided into three groups; (1) relatively short (n=30), (2) average stature (n=131), (3) relatively tall (n=153). CBCL, BEPSI, and CHQ-PF50 scores were compared among three groups. RESULTS: There were no significant differences in psychosocial burden associated with relatively short stature measured by Korean version of the BEPSI and Korean version of the CBCL scores among three groups. But general health perception score of relatively short was significantly lower than that of nonshort on the CHQ-PF50. Also, they were more used complementary medicines, milk and growth hormone compared to the nonshort. The parents' expected height of their children was 180.6+/-3.5 cm for boys and 166.7+/-3.5 cm for girls. This is respectively 90 percentile and 75-90 percentile for the Korean standard adult height. CONCLUSION: Our study shows that in Korea, Parents tended to regard relatively short children as having health problems. Also, the parental expectation for their child's attainable height is unrealistically tall, mostly due to lack of correct medical information.

We used the fluorophotometry to investigate the corneal epithelial barrier function after excimer laser photorefractive keratectomy (PRK). Twenty-five eyes of 21 subjects (13 women, 8 men) underwent PRK to correct rnyopia. Corneal epithelial healing time was measured and corneal epithelial permeability to sodiurn fluorescein was evaluated by fluorophotoinetry at I, 2, and 3 weeks after surgery. The corneal epithelial permeability increased significantly 1 week after surgery and returned to preoperative level 2 weeks after surgery. The permeability differences according to epithelial healing days and corrected diopters were not statistically significant(p>0. 05). These results suggest that PRK delays complete reconstruction of corneal epithelial barrier function. The corneal epithelium regained its functional barrier 2 weeks after PRK in patients, so, at least, during the first 2 weeks, care should be taken to miniinize further epithelial trauma from topical inedication or surgical manipulation.
