The objectives of this study were to investigate the effects of thoracic flexibility exercise on chest function and mobility and to provide the information of physical therapy for patients with idiopathic scoliosis. Forty female subjects who were diagnosed with scoliosis participated in this study and were divided into the experimental and control groups. The experimental group consisted of 20 patients who were treated with thoracic flexibility exercise program during the admission (10 days) and one month after discharge. The control group consisted of 20 patients who were not treated with thoracic flexibility exercise program. Vital capacity was measured using a respirometer. The chest expansion were calculated using differences of chest circumference between maximum inspiration and maximum expiration measured under armpits, at the junction between the sternum and xyphoid process, and at the waist. All subjects were measured two times: before the admission and at one month after discharge. Data were compared by groups using independent t-test. Vital capacity and chest expansion values (the armpit, chest and waist values) were significantly higher for the experimental group compared to those of the control group (p<.05). The findings of this study show that thoracic flexibility exercise program can lead to an increase in vital capacity and chest expansion and has a positive effects in relieving symptoms and restoring thoracic mobility.

We present a case of angiomyofibroblastoma of the vulva in a 32-year-old woman. The asymptomatic lesion measured 4×3cm and appeared as a gray-white myxoid mass on cut sections Histologically, it appeared as a relatively well-circumscribed spindle cell proliferation with alternating hypercellular and hypocellular areas and proliferation of thin-walled blood vessels. Immunohistochemically, the stromal cells expressed vimentin, CD34 and progesterone receptor, but not desmin, α-smooth muscle actin, S-100 protein and estrogen receptor. These features were similar to those of angiomyofibroblastoma as previously reported in the vulva except negativity for desmin A case of pathologically proven very rare tumor of angiomyofibroblastoma of the vulva is presented with a literature review

Bioequivalence of two flouxetine capsule, ProzacR (Lilly kora Ltd.) and LanclicR (Samsung Pharm. IND. Co.), was evalated according to the guideline of KFDA. Twenty four healthy male volunteers (21-26 years old) were divided into two groups and a randomized 2×2 cross-over study was employed. After 60mg of fluoxetine was orally administered, blood was taken at 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 24, 32, 48 and 72 hours after administration and just before administration. Plasma was analyzed for fluoxetine and internal standard (clomipramine) by a sensitive and validated HPLC assay. The pharmaco kinetic parameters (AUCt, Cmax and Tmax) wre calculated and ANOVA test was used for the statistical analysis of parameters. Differences in (AUCt, Cmax and Tmax between two capsules were -0.90, 3.46 and -14.08% respectively. All powers (1-β) for AUGt, Cmax and Tmax were more than 0.9. Detectable differences (Δ) and confidence interval were all less than ±20%. All the parameters above met the criteria of KFDA for bioequivalence and indicated that LanclicR capsules are bioequivalent to ProzacR capsules.

현재 IP 네트워크는 최선형(best-effort) 서비스 모델에서 차등 서비스를 지원하는 네트워크로 옮겨가고 있다. 이러한 다양한 서비스 레벨을 지원하기 위하여 IETF(Internet Engineering Task Force)는 통합 서비스(IntServ) 구조와 차등 서비스(DiffServ) 구조를 제안하였다. 통합 서비스는 RSVP를 사용하여 각 흐름마다 보장된 서비스를 제공한다. 차등 서비스는 차등 서비스 수준을 각 트래픽 집합에 제공하는 것으로, 통합 서비스 구조의 RSVP를 사용해 각 흐름별 상태를 유지함으로 발생하는 규모성 문제를 피한다. 차등 서비스 네트워크상의 에지 라우터, 코어 라우터 그리고 서버 등을 각 장치별로 독립적으로 구성할 경우 동작의 일치성을 달성하기 힘들다. 따라서 본 논문은 정책 기반 QoS 관리 구조를 이용한 서비스 수락 제어를 제안하였다. 제안된 관리 구조는 IETF 정책 관리 구조를 사용함으로써 차등 서비스 네트워크에서의 QoS 관리 업무를 단순화 시킬 수 있다. 또한, 각각의 라우터들의 특정 PHB 값들을 다루는 방식과는 달리 사용자, 응용 서비스, 클래스 등으로 네트워크를 추상화하는 방식을 제공한다. 이러한 높은 수준의 네트워크 정책 관점은 QoS 관리를 단순화 시키는 이점을 제공한다. 더불어 차등 서비스 네트워크에서 RSVP를 구성하는 것과 유사한 메커니즘을 제공한다.

유재덕,이세일,오석준,심기영 大韓成形外科學會 1983 Archives of Plastic Surgery Vol.10 No.2

During the past decade, microsurgery has become clinical routine and resulted in many technical innovations. Inspite of this, microsurgery still entails certain disadvantages; it is time consuming, technically demanding and sometimes results in distressful failure. The sleeve microanastomosis, proximal vessel end is inserted into distal vessel using only two extraluminal sutures, is easier and less time consuming than conventional end to end anastomosis. However, there is a few reports about the histological study to support the beneficial technique of the anastomosis. An animal study was carried out by doing 25 sleeve anastomoses of carotid arteries of white stratin rats and subsequent histological observations in different time interval in order to clarify the modesty of repair in anastomosed vessels. The following are noted as results: Patency rate of the anastomosis was 84%. No aneurysm was found at any site of the anastomosis. The narrowing of lumen of the inserted proximal vessel, the formation of thrombosis & fibrin clot in foci at proximal vessel end, and the loss of intima at the site of anastomosis were noticed in 3 days following the anastomosis. Still narrowing of the lumen of inserted vessel, the formation of thrombosis & fibrin clot in foci at proximal vessel end were persisted with focal necrosis of the media at the stitch area of dista lvessel in one week following anastomosis. Disappearance of thrombosis & fibrin clot on proximal vessel end complete restoration of intimal continuity with slight atrophy of media on distal vessel were noted in 3 week following anastomosis. Neoitima formation at anastomosis site with moderate atrophy of media on distal vessel were noted in 5 week following anastomosis. Subintimal hyperplasia was not observed except in one case of medial necrosis due to wide adventitial stripping in 8 week following anastomosis.

Background/Aims: Retroperitoneal fibrosis is a fibrosing disease process which frequently develops ureteral obstruction. Malignant retroperitoneal fibrosis has been reported that various types of cancer including cancer of the breast, stomach, prostate, lung, cervix, uteri, colon, pancreas, ovary, and even Hodgkin's disease. While the pathogenesis remains obscure, small foci of metastatic neoplasm in the retroperitoneal space can elicit a desmoplastic reaction in secondary form to malignancy. Methods: Recently we experienced 7 cases of retroperitoneal fibrosis with advanced gastric cancer. So, we report 7 cases of retroperitoneal fibrosis with clinical and radiologic characteristics. Results: The most common signs and symptoms were related irreversible renal dysfunction. The urologic finding noted medial deviation of the involved ureters and hydronephrosis Conclusions: Clinical manifestations are abdominal pain, back pain, hydronephrosis, and uremia. When sudden back pain and hydronephrosis develop in advanced malignancy, physicians should be considerd for retroperitoneal fibrosis.
