BACKGROUND: Reconstitution of hematopoiesis by means of peripheral blood stem cells(PBSC) has been widely used in patients with hematologic malignancies or solid tumors. We analyzed our experiences of PBSC collections with a MCS3p(Haemonetics Corp. Braintree, MA,USA) and investigated factors that may affect the collection of PBSC. METHOD: The forty-seven harvests in 11 cancer patients(median age 48, 4 males: 7 females) were performed during marrow recovery after administration of anticancerous regimens and and hematopoietic growth factors. RESULTS: Median number of WBC & mononuclear cells(MNCs) in preapheresis was 4,700/pl and 1,472/pl, retrospectively. A total of 11.2 x 10'(range 5.4-17.0) MNCs were collected from 7.2 l (5.5-8.9) blood processed per procedure. The mean percentage of CD34 positive cells in the product was 1.9%(0.9-2.9). Collection efficiency was 58.1%. While age of patients or total processed blood volume did not affect for total number of MNC collected, the number of WBCs including MNCs on the day of harvest was an importanr factor for higher yield of MNCs(P<0.05). CONCLUSION: We concluded that Haemonetics MCS3P. Is a fully automated blood cell separator with good collection efficiency for hematopoietic progenitor cells.(Korean J Blood Transfusion 10(1): 35-41,1999)

BACKGROUND: Recently, clinical use of fresh frozen plasma(FFP) has increased in all blood transfusion activity. But inappropriate uses of FFP may be serious problem due to adverse transfusion reactions, viral transmission, and economic aspects. The aim of this study is to justify clinical indication of FFP by receiving the inappropriate use of them. METHODS: Analyzing hospital records of 115 patients transfused with FFP at Kyung Hee Medical Center from January to April 1998, retrospectively, we investigated the purpose of transfusions, the volume of transfused FFP, and the results of pre- and post-coagulation tests. RESULTS: The most common purpose of transfusions of FFP was plasma volume replacement after surgical operation. Coagulation tests of pre- and post-transfusion were performed 85% and 47%, respectively. Fifty-seven patients(88%) transfused FFP have shown normal results in pre-coagulation tests, and the volume replacement with FFP was done inadequately in 62 cases(54%). CONCLUSION: We conclude that, in order to eliminate side effects due to inappropriate use of FFP, and protect patients, it is necessary to make guidelines of FFP transfusion, educate hospital staffs regularly, and perform pre- and post-coagulation tests routinely for the patients who need FFP transfusion.

BACKGROUND: Recently, according to many studies, variable factors have been known to be associated with physical fitness. The factors such as obesity and inactivity are associated with poor physical fitness, but regular exercise is associated with good physical fitness. In our country, these studies are not yet reported. And so, this study was designed to investigate the factors associat,ed with physical fitness. METHODS: From May 1st, until July 30th 1996, we recruited the 411 subjects who visited the Health Promotion Center at Seoul National University Hospital. Data related to sex, age, exercise, job, cigarette smoking, alcohol consumption were obtained by self-administered Questionnaire. Obesity index was calculated by the percentage of standard body weight. And VO2max were obtained by submaximal bicycle ergometer test. High level exercise group was defined as the persons who had taken exercise more than 3 times a week and 20 minutes per session, and moderate exercise group was defined as the persons who had taken exercise one or two times a week and 20 minutes per session, and sedentary group was defined as the persons who had taken exercise more than 20 minutes less than one time per week. RESULTS: The subjects were 230 males(56%), total numbers were 411. The results were as follows. Compaired to women and nonexercise group, men and exercise group had high VO2max(p<0.005). The relationship between VO2max and age showed negative, and the VO2max of obese group(obesity index>_120) was greater than that of nonobese group. Any significant relationships between VO2max and job, disease were not found. In multiple regression analysis, significant relationships between VO2max and age, sex, exercise type, and obesity index were observed(p<0.01). CONCLUSIONS: We concluded that there were significant relationships between VO2max and obesity index, exercise group.

The cavus foot is a deformity characterized by an elevated medial longitudinal arch and a hindfoot varus with plantarflexed 1st ray. The etiology of cavus foot is usually related to neuromuscular disease or idiopathic cause. Thorough clinical and radiographic evaluation is required for differentiating etiology of the cavus. Most cases of cavus foot are stable and slowly progressive deformities which can initially be managed with conservative treatment including orthoses and physical therapies. Determining whether the deformity is flexible or rigid, the apex of the deformity and any muscle imbalances in foot and ankle is important for achievement of an adequately balanced plantigrade foot. Treatment should include systematic preoperative planning for selection of appropriate procedures for maintaining a functional and flexible foot with combinations of soft-tissue release, osteotomy, tendon transfer, and arthrodesis.
