Objective: This study was designed to evaluate diagnosis and complication, prognosis during clinical study of cases of intrauterine fetal death. Methods and materials: This is a clinical study of 56 cases of the intrauterine fetal death among 8064 deliveries at Seoul Sunchunhyang university hospital during 5 years from January, 1994 to December, 1998. Results: The incidence was 0.7%. The age distribution of mothers was 18 - 44 years and was highest in the 25 - 29 years range(46.4%). The parity was the most highest in the nulliparous group(51.8%). The most common gestational weeks was 20 - 28 weeks gestational period(46.4%), and most common presentation was cephalic(73.5%). The most common weights of the intrauterine fetal death was from 5,00gm to 1,000g(48.2%). The mode of the most common delivery was the induction of delivery(57.2%). The etiologic factors were: unknown(42.9%), preeclampsia(17.9%), chorioamnionitis(14.3%), congenital anomaly(12.5%), abruptio placenta(7.1%), cord complication(3.6%), placenta previa, death of one for twin. There were 2 cases of maternal complication(DIC, Uterine atony). Conclusion : Intrauterine fetal death should be diagnosised early and treated properly to reduce risk of the maternal complication.

정신영,이재태,서명랑,유정아,배진호,안병철,황재석,정재민,하정희,이규보 대한핵의학회 2003 핵의학 분자영상 Vol.37 No.6

목적: ^(99m)Tc-lactosylated serum albumin (^(99m)Tc-LSA)은 간세포에 특이적으로 결합하는 간수용체 영상용 방사성의약품으로 새로이 합성되었다. 간섬유화를 유발하는 dimethylnitrosamine (DMN)을 투여한 간 손상 휜쥐 모델에서 ^(99m)Tc-LSa의 역동학적인 간섭취를 조사하고 간효소치의 변화와 조직학적 소견을 비교하여, LSA의 간섭취가 간기능의 변화를 반영하는지를 연구하였다. 대상 및 방법: SD계 흰쥐에 DMN를 27 mg/kg으로 복강 내 주사하여 급성 간손상을 유도하고 대조군과 비교하였다. DMN을 주사한 흰쥐를 3일(DMN-3), 8일(DMN-8), 21일(DMN-21)에 ^(99m)Tc=LSA (1,665 mg/kg) 29 MBq를 정맥 주사하여, 30분 동안 동적 영상을 획득하고 간과 신장부위에 관심영역을 설정하여 간과 심장부위의 시간방사능 곡선을 얻었다. 간기능 평가를 위해 시간방사능 곡선을 이용하여 간섭취지수와 혈중제거지수를 구하였고 곡선 최적화를 시행하였다. DMN 투여군과 대조군의 간효소치의 변화와 간조직의 광학현미경 소견을 비교하였다. 결과: 대조군에서는 ^(99m)Tc-LSA가 빠르게 간에 섭취되고 혈중에서 제거되었으나 DMN을 처리한 군에서는 간섭취가 낮았다. 간섭취지수의 비교에서 대조군에 비해 DMN 처리군에서 유의하게 간섭취지수가 낮았다(DMN-3: 0.842, DMN-8: 0.898, DMN-21: 0.91, 대조군: 0.96, p<0.05). 혈중제거지수의 비교에서도 대조군에 비해 DMN 처리군에서 혈중제거지수가 유의하게 높았다(DMN-3: 0.731, DMN-8: 0.654, DMN-21: 0.604, 대조군: 0.473, p<0.05). 비선형 회귀분석에서 R_(2) 값은 0.9이상으로 좋은 일치를 보였고, 대조군에ㅓ K값이 DMN처리군에 비해 크고(DMN-3: 0.28, DMN-8: 0.41, DMN-21: 0.46, 대조군: 0.97, p<0.05), T_(1/2)값은 작았다(DMN-3: 2.5, DMN-8: 1.7, DMN-21: 1.5, 대조군: 0.7, p<0.05). 간효소치의 변화는 DMN-3군에서는 대조군에 비해 상승하였으나 DMN-8, DMN-21군에서는 간효소치의 상승이 관찰되지 않았다. 간조직 소견의 경우 DMN-3군에서 중심정맥 주위에 괴사가 관찰되었으나 DMN-8군, DMN-21군에서는 미약한 정도의 염증세포 침윤만이 관찰되었다. 결론: ^(99m)Tc-LSA 간신티그래피의 간섭취 정도는 간손상과 반비례하였으며 간섭취의 변화는 조직학적 손상이 심한 정도와 간손상후 회복되는 과정을 반영하여 주었다. ^(99m)Tc-LSA 간신티그래피가 간손상을 평가하고 간손상후 회복되는 과정을 추적하는 간수용체 영상용 방사성 의약품으로 사용될 수 있을 것으로 생각된다. Objects: ^(99m)Tc-lactosylated human serum albumin(LSA) is a newly synthesized radiopharmaceutical that binds to asialoglycoprotein receptors, which are specifically presented on the hepatocyte membrane. Hepatic uptake and blood clearance of LSA were evaluated in rat with acute hepatic injury induced by dimethylnitrosamine(DMN) and results were compared with corresponding findings of liver enzyme profile and these of histologic changes. Materials and Methods: DMN (27 mg/kg) was injected intraperitoneally in Sprague-Dawley rat to induce acute hepatic injury. At 3(DMN-3), 8(DMN-8), and 21(DMN-21) days after injection of DMN, LSA injected intravenously, and dynamic images of the liver and heart were recorded for 30 minutes. Time-activity curves of the heart and liver were generated from regions of interest drawn over liver and heart area. Degree of hepatic uptake and blood clearance of LSA were evaluated with visual interpretation and semiquantitative analysis using parameters (receptor index : LHL3 and index of blood clearance : HH3), analysis of time-activity curve was also performed with curve fitting using Prism program. Results: Visual assessment of LSA images revealed decreased hepatic uptake in DMN treated rat, compared to control group. In semiquantitative analysis, LHL3 was significantly lower in DMN treated rat group than control rat group (DMN-3:0.842, DMN-8: 0.898, DMN-21: 0.91, Control: 0.96, p<0.05), whereas HH3 was significantly higher than control rat group (DMN-3: 0.731, DMN-8: 0.654, DMN-21: 0.604, Control: 0.473, p<0.05). AST and ALT were significantly higher in DMN-3 group than those of control group. Centrilobular necrosis and infiltration of inflammatory cells were most prominent in DMN-3 group, and were decreased over time. Conclusion: The degree of hepatic uptake of LSA was inversely correlated with liver transaminase and degree of histologic liver injury in rat with acute hepatic injury.

Objective: The purpose of this study was to evaluate clinical efficacy of fetal fibronectin as a marker to predictor of preterm labor. Materials & Methods: The study group consisted of sixty-eight healthy pregnant women, at gestational age between 24 and 36 weeks, who visited our department with vaginal discharge from April, 1995 to December, 1997. For comparison, we divided all of the pregnant women into two groups by the result of ROM-Check^®, positive groups(N=21) and negative groups(N=47). When preterm labor appeared, 50mg of ritodrine hydrochloride(Yutopar^®) mixed I liter of 5% dextrose solution was administered slowly intravenously. Results: 1) The gestational age at delivery and the interval time from admission to delivery in the positive groups were significantly shorter than those of the negative groups(p<0.05). 2) The positive groups had significantly lower birth weight and Apgar scores than the negative groups(p<0.05). 3) Among the negative groups, in case of tocolytics administration, the interval time from admission to delivery significantly delayed more than that time in case of no tocolytics administration(p<0.05). Conclusions: The detection of the fetal fibronectin in vaginal discharge had a useful method as a predictor of preterm labor. Tocolytics was more effective in the negative groups than in the positive groups.

조영완,박석주,진한영,김준영,이재익,강명주,박정하,윤정희,박성재,지삼룡,이연재,이상혁,설상영 인제대학교 2006 仁濟醫學 Vol.27 No.-

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.

For the purpose of studying the properties of calcium channel, the effect of pH on the KCl induced Ca-uptake in the isolated porcine intestinal sarcolemmal vesicles, which were loaded with high KCl was investigated. The obtained results were as follows; 1. Ca-uptake in the membrane of depolarized state by high KCl, compared with that of polarized state by low KCl in the medium was increased significantly(increased about 95.7% for 30 seconds, pH 7.4). 2. Ca-uptake in the membrane of predepolarized state by high KCl, compared with that of polarized state by low KCl was also increased significantly but less than that of depolarized state by high KCl (increased about 66.7% for 30 seconds, pH 7.4). 3. Influence of pH on the Ca-uptake of various membrane state was increased or decreased according to pH changes. Ca-uptake in the membranes of incubated at pH 6.0 was decreased about 48.5%, but increased about 10% and 36% at pH 8.0 and 9.0 respectively, compared with that incubated at pH 7.4. 4. KCl-induced Ca-uptake at the various pH conditions, was not inhibited by the pretreatment of diltiazem(10^-6M). From the above results, it was concluded that KCl-induced Ca-uptake at the various pH conditions in the isolated sarcolemmal membranes, prepared from porcine intestinal smooth muscle, was not mediated through channels which are inhibited by organic Ca-antagonists.
