Abstract-In order to investigate the pharmacological properties of New Wonbang Woohwangchungsimwon Liquid (NSCL), effects of Wonbang Woohwangchungsimwon Liquid (SCL) and NSCL were compared. In isolated rat aorta, NSCL and SCL showed the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6 M) regardless to intact endothelium or denuded rings of the rat aorta. Furthermore, the presences of the inhibitor of NO synthase and guanylate cyclase did not affect the relaxing effect of NSCL and SCL. NSCL and SCL inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs), NSCL and SCL significantly decreased heart rate. NSCL and SCL, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, NSCL and SCL had no effects on parameters of action potential such as resting membrane potential, action potential amplitude, APD_90 and V_max at low doses, whereas inhibited the cardiac contractility at high doses. These results suggested that NSCL and SCL have weak cardiovascular effects with relaxation of blood vessels and decrease of heart rate, and that this effect is no significant differences between cardiovascular effects of two preparations.

조세현,정순택,박형빈,황선철,하용찬,황인환 대한골절학회 2004 대한골절학회지 Vol.17 No.4

목적: 장관골 감염성 불유합의 치료 시 항생제 혼합 시멘트 정을 이용한 이단계 재건술의 결과를 분석하고자 한다. 대상 및 방법: 1998년 1월부터 2002년 9월까지 장관골 감염성 불유합으로 이단계 재건 수술을 받은 41예 (대퇴골 26예, 경골 15예)를 대상으로 하였다. 일단계 수술에서는 광범위한 변연 절제술, 부골 제거 및 세척술과 기존 고정 장치의 제거 또는 외고정 장치로의 교환을 시행한 후 시공 (dead space)과 불유합 주변 연부조직 내 항생제 혼합 시멘트 정을 삽입하였다. 임상적 감염 증상이 호전된 평균 8.7주 (3주~32주) 후 이단계 재건술로서 Ⅰ군은 내고정 장치 (금속판 5예, 골수강내 금속정 8예), Ⅱ군은 외고정 장치 (Ilizarov 25예, Monofixator 3예)로 각각 고정하고 17예에서는 골내 이동술이나 골 연장술을 시행하였다. 양군 모두 필요한 경우 골 이식과 시멘트 정의 교환을 추가하였다. 추시 기간은 16개월에서 최장 71개월로 평균 45개월 이었다. 치료 결과는 골유합 기간 및 Paley 방법에 의한 방사선상 골유합 상태와 하지 기능으로 평가하였다. 결과: Ⅰ군 13예 전부와 Ⅱ군 28예 중 26예에서 감염의 치료와 골유합을 얻었다. 이단계 재건술 후 골 이식술, 골 소파술, 외고정 핀 교환과 각변형 교정술, 피부 이식 또는 근육 피판 회전술 등의 보조적 시술이 Ⅰ군은 평균 2회, Ⅱ군은 평균 6.2회 추가되었다. 평균 골유합 기간은 Ⅰ군이 19.3주이고 Ⅱ군이 23.1주로 내고정군이 더 빨랐다. 방사선상 Paley 골유합 상태는 Ⅰ군이 우수 8예, 양호 5예이었고, Ⅱ군이 우수 18예, 양호 7예, 보통 1예, 불량 2예 이었다 (p=0.492). 기능적 결과는 Ⅰ군에서 우수 6예, 양호 6예, 보통 1예 이었고, Ⅱ군에서는 우수 10예, 양호 13예, 보통 3예, 불량 2예 이었다 (p=0.267). 결론: 항생제 혼합 시멘트 정의 골수염 치료 효과가 관찰되었으며, 감염이 호전된 후 내고정 장치로 교환해 준 군이 외고정을 유지한 군에 비하여 추가 수술 횟수가 적고, 골유합 기간도 빨랐다. Purpose: To evaluate treatment results between internal na external fixation groups in two-stage reconstruction of infected nonunion of long bones using antibiotics-impregnated cement beads. Materials and Methods: In the first stage, preexisting hardwares were removed and radical debridement was done. The dead space was filled with antibiotics -impregnated cement beads and the nonunion sits was immobilized by external fixation, cast or skeletal traction. In the second stage, all cases were divided into two groups; the nonunion was fixed by internal fixation in group Ⅰ versus external fixation in group Ⅱ. The intervening period between the first and second stage was average 8.7 weeks (range, 3~23 weeks). Results: The follow-up period was average 45 months (range, 16~71 months). Infection control and bone union were achieved in all 13 cases of group Ⅰ. Infection recurred in two of 28 cases in group Ⅱ, one underwent above-knee amputation and the other case was lost in follow-up. The mean number of supportive operations including repeated curettage, augmentation and change of infected pins, angular correction, and soft tissue flap was average 2 and 6.2 times respectively in group Ⅰ and group Ⅱ. Bony union period was average 19.3 and 23.1 weeks in each group. According to Paley's classification, group Ⅰ was similar to group Ⅱ in bony and functional result (p>0.05). Conclusion: Antibiotics-impregnated cement beads provided positive effect on infection control. Internal fixation group showed less number of additional operations and earlier bony union than external fixation group.

The role of education is to create a man of ability for development of the nation and society in Korea. The function of the study in the university for a developing country has been repeated a vicious circle by being the financial destitution. But we must find a way out of such vicious circle difficulties, reforming the higher education in the university, and develop the knowledge industry in the developing country. To reform the higher education, a university education, we need the necessary reforming personnels, the financial resources and the governmental consideration etc.. And the president with the necessary reforming personnels must display his ability of leadership, plan for the educational reform in the university and carry out the plan. In the case of Jeju National University, the reforming preconditions, personnels, financial and political etc., are not so good. We need to train and secure the necessary reforming personnels and ensure the financial preconditions and expect to do the governmental consideration. So We want to be enacted the special bedget in the National Assembly. And then the above various problems shall be planned for the eductional reform in the university, and the president of the university with them shall try to perform the reforming plan.

One hundred Korean terrestial snakes,i.e.,7 Elaphe rufodorsata,17 E. dione, 10 Dinodon rufozonatum rufozatum,37 Natrix tigrina lateralis,21 Agkistrodon blomhoffii brevicaudus,6A.calibinosus and 2A. saxatiilis were examined from June 17, 1981 to Jun 1, 1982, to observe the fauna of Korean cestode parasities. They were collected from 13 localities of southern Korea: i.e., Chunseong Gun, Hong-cheon Gun, Hoengseong Gun, Weonseong Gun, Samcheog Gun, Gangweon Do; Namyangju Gun, PAju Gun, Ganghwa Gun, Gyeonggi Do; Youngdong Gun, Jeweon Gun, Chungcheongbug Do; Jangheung Gun, Jeonlanam Do; Sancheong Gun, Gyeongsangam Do and Bugjeju Gun, Jeju Do respectively. The results could be summarized as follows: 1. A total of 61 snakes was found to be infected withsparganum larvae of Spirometra mansoni out of 100 examined. Snakes from 11 localities were infected. By species of snake, N.t. lateralis and A.b. brevicaudus showed the higher infection rates. The mean density was 11.0 per examined snake and 18.1 per infected snake respectively. A. caliginosus and A. saxatilis were new hosts of spatganum in Korea. 2. Trtrathyridium of Mesocestoides sp. was found in one snake, Elaphe rufodorsala collected from ChunSeong Gun, Gangweon Do. A total of 16 tetrathyridia was found at serosa and mesemtery of the snake. The morphology of the larvae was described. This was thr first record of recovery of thtrathyridia in any vertebrate intermediate host in Korea. Elaphe rufodorsata was a new host. 3. proteocephalus japonensis(Yamaguti, 1935) n.comb.(syn.: Ophiotaenia Japonensis Yamaguti, 1935) were found in 10 snakes which were collected from Hongcheon Gun, Weonseong Gun, Namyangju Gun, Paju Gun, Jeweon Gun, and Sancheong Gun repectively. The infected snakes were Agkistrodon blomhoffii brevicaudus, A. caliginosus, A. saxatilis and Natrix tigrina lateralis. The habit was small instetine. The measurement data and morpholigy were described. The preaently observed worms were longer than those of original description and was a difference in mumber of uteerine branches. A. blomhoffii brevicaudus, A. caliginosus, A. saxatilis were new hosts for this protecephalid cestode. Korea was added to list of the locality.

In order to investigate the pharmacological properties of New Woohwangchungsimwon Liquid (NCL), efects of Woohwangchungsimwon Liquid (CL) and NCL were compared. In isolated rat aorta, NCL and CL showed the relaxation of blood vessels in maximum contractile response to phenylephrine (10^6M) without regard to intact endothelium or denuded rings of the rat aorta. Furthemore, the presences of the inhibitor of NO synthase and guanylate cyclase did not affect the relaxation of NCL and CL. NCL and CL inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dosedependent manner. In conscious spontaneously hypertensive rats (SHRs), NCL and CL significantly decreased heart rate. NCL and CL, at high doses, had a negative inotropic effect that was a decrease of LVDP and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In excised guinea-pig papillary muscle, NCL and CL had no efects on parameters of action potential at low doses, whereas inhibited the cardiac contractility at high doses.

Abstract-In order to investigate the phamacological properties of New Wonbang Woohwangchungsimwon Pill (NSCH), effects of Wonbang Woohwangchungsimwon Pill (SCH) and NSCH were compared using various experimental models. In rat aorta, NSCH and SCH made the relaxation of blood vessels in maximum contractile response to phenylephrine (10^-6 M) regardless to endothelium containing or denuded rings of the rat aorta. Furthermore, the presence of the inhibitors of NO synthase and guanylate cyclase did not aftect significantly the relaxing effects of NSCH and SCH, NSCH and SCH inhibited the vascular contractions induced by acetylcholine, prostaglandin endoperoxide or peroxide in a dose-dependent manner. In conscious spontaneously hypertensive rats (SHRs). NSCH and SCH decreased significantly heart rate. These, at high doses, had a negative inotropic effect that was a decrease of left ventricular developed pressure and (-dp/dt)/(+dp/dt) in the isolated perfused rat hearts, and also decreased the contractile force and heart rate in the isolated rat right atria. In guinea-pig papillary muscle, these had no effects on parameters of action potential such as action potential amplitude (APA). V_max and resting membrane potential (RMP) at low doses, whereas inhibited the cardiac contractility at high doses. Furthermore, these had a significant inhibitory effects on palpitation of the heart in normotensive rats and SHRs. These results suggest that NSCH and SCH have weak cardiovascular effects, and that there is no significant differences between cardiovascular effects of two preparations.

We discuss the theory of motion estimation and motion compensation. The proposed algorithm uses more information from the input video image sequence than the traditional two-frame pel-recursive algorithms. And it uses fewer assumptions on the motion vectors among different video frame pairs. This paper shows two three-frame pel-recursive algorithm for predictive motion compensation which can estimate the d₁(from the previous frame f_t-1 to current frame, f_t) and d₂(from the frame before the previous frame f_t-2 to the previous frame, f_t-1) simultaneously, and three frame information to update the motion vector d₁when the past motion vector d₂is available.

박형빈,강번중,송해룡,구경회,정순택,조세현 대한골절학회 2002 대한골절학회지 Vol.15 No.4

목 적 : 경골 골절에서 골수정 고정술후 발생하는 교합나사 파단의 빈도와 발생 원인을 밝히고자한다. 대상 및 방법 : 1995년 3월부터 2000년 10월까지 골수정으로 치료하였던 경골 간부골절 82예중 내고정물 파단이 발생하거나 골유합이 이루질 때까지 추시 가능하였던 75예를 대상으로 하였다. 내고정물 파단 빈도와 위치, 골절의 양상, 술후 골절부 신연 및 골유합 이상 여부를 조사하였다. 결 과 : 교합나사 파단은 7예였고 (9.3%), 근위부 두 번째 나사의 파단이 가장 흔하였다. 교합나사으 ㅣ파단은 AO분류 B형과 C형 골절, 술후 골절부가 신연된 경우, 개발성골절, 자연유합 및 불유합의 경우 발생하였다. 결 론 : 교합나사 파단의 주된 요인은 골절부의 골과 골 접촉이 불안정하기 때문이며, 개방성 골절, 지연유합 및 불유합도 교합나사 파단의 위험인자라고 생각한다. 교합나사 파단을 예방하기 위해서는 수술시 골절부 신연을 피해야하며 골절부 골접촉이 불안정한 경우 완전 체중부하를 골유합시까지 제한하여야할 것으로 생각한다. Purpose : The aims of this study were to investigate the prevalence and the causes of crew breakage in tibia nailing. Materials and Methods : Between 1995 and 2000, eighty-two tibial diaphyseal fracture were treated with interlocking nails. The loss of follow-up was 7 cases. We retrospectively reviewed seventy-five cases. We investigated the rate and location of metal failure and evaluated the fracture pattern, the presence of distraction after nailing and union abnormality. Results : Screw breakage was identified in seven cases (9.3%) and most frequently occurred on the second proximal locking screw. Screw breakage occurred in AO type B or C type fractures, fracture site distraction after nailing, open fracture, delayed union and nonunion. Conclusion : The main cause of screw breakage is unstable bone to bone contact on the fracture site caused by comminution of distraction. The open fracture, delayed union, and nonunion also contributing factors for screw breakage. For preventing screw breakage, it is necessary to avoid fracture site distraction and delay full weight bearing in cases having unstable fracture site contact.
