Purpose: We have evaluated the compliance of hormone replacement therapy. Method: There are 185 climacteric women who are divided into three groups (Group I, Group II, Group III). Group I is given conjugated equine estrogen(CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate(MPA, 5mg, day 1-12). Group II is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 2.5mg, day 1-30), Group III is given only conjugated equine estrogen(CEE, 0.625mg, day 1-30). Results: 1) The compliance rate of hormone replacement therapy during three months is 77.9% including each Group I : 77.7%, Group Ⅱ : 76.1%, Group Ⅲ :80.4%. 2) The compliance rate of hormone replacement therapy during six months is 60.7% including each Group Ⅰ:52.9%, Group Ⅱ: 56.4%, Group Ⅲ: 79.5%. 3) The compliance rate of hormone replacement therapy during nine months is 49.7% including each Group Ⅰ: 45.5%, Group Ⅱ:41.7%, Group Ⅲ: 64.3%. 4) The compliance rate of hormone replacement therapy during a year is 44.4% including each Group Ⅰ: 40.2%, Group Ⅱ:35.3%, Group Ⅲ: 59.5%. Conclusion : It is vital that we maximize compliance if patients are to receive the full benefits from hormone replacement therapy. We think that physicians who prescribe hormone replacement therapy for climacteric women should enough explain the purpose, risks, and side effect of treatment for maximizing compliance of hormone replacement therapy.

This paper deals with the flexural behaviors and design method of R.C beams strengthened by carbon fiber sheets. The behaviors of strengthened beams which were preloaded are compared with that of a beam which was not preloaded. The structural behaviors of strengthened beams are compared with flexural theory and current codes. According to the results, it is shown that strengthening of damaged beams is structurally efficient and that the strength of the strengthened beams are improved. The composite action between concrete and CFS are preserved after strengthening regardness of preloading. And, it is shown that the behavior of strengthened beams follow simple laws of mechanics and can be predicted by codes.

Acanthamoeba spp. spread in soil, ponds, air and swimming pool, cause a granulomatous amoebic meningitis and amoebic keratitis in human and experimental animals. Their classification had depended upon morphological characteristics and physiological conditions such as thermophilic status and generation times. However, because amoeba species showed the morphological and physiological diversity in isolates, many attempts have been made on identification of Acanthamoeba spp. Restriction fragments length polymorphism (RFLP) analysis of IBS-small subunit ribosomal RNA (srRNA) was an useful tool for classification among morphologically and genetically closely-related species. In this study, 18S-srDNAs of amoebae were amplified by PCR with primer encoding 18S-srRNA gene and digested with restriction endonudeases, and RFLP analysis was applied on classification of Acanthamoeba Korean isolates (YM-4, YM-5 and YM-7), comparing with reference amoebae, A. culbertsoni, A. polyphaga and A. royreba. Trophozoites of six Acanthamoeba spp. had typical acanthopoda, but did not show any morphological differences. Cyst of Acanthamoeba sp. YM-7 was similar to that of A. polyphaga which was designated as group Ⅱ Acanthamoeba. Morphologically other amoebae belonged to group Ⅲ Acanthamoeba. Digestion of 18S-srDNA with six enzymes, Dde Ⅰ, Hae Ⅲ, Hind Ⅲ, EcoR Ⅰ, Rsa Ⅰ and Sph Ⅰ, resulted in various DNA fragments. Using the method of Nei and U (1979) for RFLP analysis, genetic divergence was not observed between A culbertsoni and Acanthamoeba sp. YM-4. Between A. culbertsoni and Acanthamoeba sp. YM-5, genetic distance was 0.070, 0.364 between Acanthamoeba sp. YM-4 and A. polyphaga, and 0.277 between Acanthamoeba sp. YM-7 and A. polyphaga. In comparison with A. culbertsoni and A. polyphaga, Acanthamoeba sp. YM-7 showed genetic distance of 0.330 and 0.154, respectively. Thus, Acanthamoeba sp. YM-7 is a similar species to A. polyphaga. Acanthamoeba sp. YM-5 is a different species from A. polyphaga, but closely-related to A. culbertsoni. Acanthamoeba sp. YM-4 can be classified as a subspecies or a strain of A. culbertsoni.

Background : Exccssive sweating of the facial, Palms, axilla and soles, is a psychologically and occupationally distressing and sometimes disabling condition. VideoUassisted thoracoscopic surgery (VATS) is now mostly performed for treating of the facial, palmar and axillary hyperhidorsis. This study was designed to evaluate the results and complication of sympathicotomy of the primary hyperhidrosis. Material and methods : From June 1999 to May 2002, 55 patients ( 30 males and 25 females ) suffering from primary hyperhidirosis were operated. The mean age of patients was 24.0±6.0 years. Bilateral thoracoscopic sympathicotomy was resected the only T2, T2 & T3, onlY T3, T3 & T4 and T2, T3 & T4. The mean follow up period was 18±6.5 months. Results : Mean operation time was 61.2+25.0 minutes and the mean elevation of palmar temperature after sympathicotomy was 1.13±0.2℃. There were no operative deaths but some complication existed : 42 patients (76%) complained the compensatory hyperhidrosis, and 5 patients was developed the postoperative pneumothorax. Sweating decreased in 43% of the planter hyperhidrosis. Conclusion : Most of the patients were satisfied with the postoperative results of the thoracoscopic sympathicotoiny. We conclude that thoracoscopic sympathicotomy is a simple, safe and effective technique in primary hvPcrhidrosis, but satisfaction has been decreased by the compensatory hyperhidrosis; therefore, it is important to thoroughly explain the compensatory sweating. We recommend that the less extent of sympathicotomy decrease the incidence of compensatory hyperhidrosis.

Background : This study aims to assess the efficacy of VATS pleurodesis in the treatment of spontaneous pneumothroax. Method and material : 131 consecutive patients who underwent videoUassisted thoracoscopy (VATS) bullectomy and pleurodcsis procedure in Chosun Uniservity Hospital between May 1999 and June 2003 were included in the study. Theses patients were performed the VATS with Talc pleurodesis (Group A, n=72), VATS with Doxycycline pleurodesis (Group B, n=36), and VATS with reinforcement by absorbable mesh (Surgicel_(R)) and fibrin glue (Group C, n=23). The follow-up period was from 4 months to 30 years. Result: The patient's population consisted of 117 men and 14 women, and the mean age of the patients was 25.6 years. Recurrence rate was 1.4% ( 1 of 72 patients) in group A, 5.6% (2 of 36 patients) in groug B and 0% (0 of 23 patients) in group C. The median removal period of drainage chest tube was 3.3 days. Conclusion : Careful surgical technique is fundamental in reducing early air leakage and recurrence. Moreover, the covering of the suture area with an absorbable mesh and the fibrin glue is safe and effective method with an acceptable recurrence rate.

The outcome of hematopoietic stem cell transplantation in Korean children with hemophagocytic lymphohistiocytosis.Pediatr Transplantation 2010: 14:735–740. © 2010 John Wiley & Sons A/S.</P><P>Abstract: </P><P>Chemoimmunotherapy-based treatments have improved the survival of patients with HLH, but outcomes of the patients are still unsatisfactory. We report here the outcome of Korean children with HLH who underwent HSCT, which was analyzed from the data of a nation-wide HLH registry. Retrospective nation-wide data recruitment for the pediatric HLH patients diagnosed between 1996 and 2008 was carried out by the Histiocytosis Working Party of the Korean Society of Hematology. Nineteen patients who received HSCT among the total of 148 enrolled children with HLH were analyzed for the transplant-related variables and events. The probability of five-yr survival after HSCT was 73.3% with a median follow-up of 57. Two months compared to 54.3% for the patients who were treated with chemoimmunotherapy only (p<I> </I>=<I> </I>0.05). The reasons for HSCT were active disease after eight wk of initial treatment (n = 9), relapsed disease (n = 5), and FHL (n = 5). Fourteen patients are currently alive without disease after HSCT, four patients died of treatment-related events (infection in two and graft failure in two) at early post-transplant period, and one patient died of relapse at one yr post transplantation. The survival of patients who were transplanted because of active disease after eight wk of initial treatment was worse compared to those patients who had inactive state at that time (60.6% vs. 100%, respectively, p<I> </I>=<I> </I>0.06). Of the four patients who received transplants using cord blood, three died of graft failure (n = 2) and relapse (n = 1). The five-yr probability of survival after HSCT according to the donor type was 85.7% for the MRDs (n = 6), 87.5% for the MUDs (n = 8), and 40% for the MMUDs (n = 5) (p<I> </I>=<I> </I>0.03). Other variables such as age, CNS involvement at the time of diagnosis, the etiology of HLH (familial or secondary), and the conditioning regimens had no influence on the five-yr OS of the HLH patients who underwent HSCT. HSCT improved the survival of the patients who had familial, relapsed, or severe and persistent SHLH in the Korean nation-wide HLH registry. Although numbers were small, these results are similar to other reports in the literature. The disease state after initial treatment, the stem cell source of the transplant, and the donor type were the important prognostic factors that affected the OS of the HLH patients who underwent HSCT.</P>
