Background and Objective: There has been no universally agreed standard chemotherapy regimen for patients with advanced biliary tract carcinomas (BTC). We aimed to fully display and evaluate the clinical evidence for gemcitabine or gemcitabine-cisplatin combination for advanced BTC. Methods: Systematic searches were performed to identify relevant randomized controlled trials (RCTs) and uncontrolled trials. Overall survival (OS), progression-free survival (PFS), overall response rates (ORR), tumor control rates (TCR), and toxicity were evaluated. Evidence levels of the results were evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Results of the eleven gemcitabine-cisplatin trials and ten gemcitabine trials showed both chemotherapy regimens had benefits with reference to mean OS (8.63 vs. 8.79 months), mean PFS (4.86 vs. 4.72 months), pooled ORR (25.3% vs. 19.6%) and TCR (55.2% vs. 53.1%). Two RCTs showed the gemcitabine-cisplatin combination to prolong the mean PFS (mean difference [MD] 2.57, 95%CI 1.69 3.45), substantially increasing the mean OS (MD 3.59, 95% CI 3.48 3.71), and producing a similar effect in ORR (risk ratio [RR] 1.59, 95%CI 1.04 2.43), increasing TCR (RR 1.15, 95%CI 1.02 1.31) compared with gemcitabine alone, with generally manageable grade 3 or 4 adverse events. The evidence level of OS was moderate, and other outcomes (ORR, PFS, TCR, anaemia, neutropenia) were at low evidence levels. Conclusion: Available evidence was limited with low quality, which showed that both gemcitabine-cisplatin and gemcitabine alone had clinical activity with acceptable safety profiles, and gemcitabine-cisplatin appeared to be more useful for advanced BTC patients than gemcitabine alone.

Silymarin has been introduced fairly recently as a hepatoprotective agent. But its mechanisms of action still have not been well established. The aim of this study was to make alcoholic fatty liver model of rats in a short time and investigate silymarin's protective effects and possible mechanisms on alcoholic fatty liver for rats. The model of rat's alcoholic fatty liver was induced by intragastric infusion of ethanol and high-fat diet for six weeks. Histopathological changes were assessed by hematoxylin and eosin staining (HE). The activities of alanine transarninase (ALT) and aspartate aminotransferase (AST), the levels of total bilirubin (TBIL), total cholesterol (TC) and triglyceride (TG) in serum were detected with routine laboratory methods using an autoanalyzer. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx) and the level of malondialdehyde (MDA) in liver homogenates were measured by spectrophotometry. The TG content in liver tissue was determined by spectrophotometry. The expression of nuclear factor-${\kappa}B$ (NF-${\kappa}B$), intercellular adhesion molecule-1 (ICAM-1) and interleukin-6 (IL-6) in the liver were analyzed by immunohistochemistry. Silymarin effectively protected liver from alcohol-induced injury as evidenced by improving histological damage situation, reducing ALT and AST activities and TBIL level in serum, increasing SOD and GPx activities and decreasing MDA content in liver homogenates and reducing TG content in liver tissue. Additionally, silymarin markedly downregulated the expression of NF-${\kappa}B$ p65, ICAM-1 and IL-6 in liver tissue. In conclusion, Silymarin could protect against the liver injury caused by ethanol administration. The effect may be related to alleviating lipid peroxidation and inhibiting the expression of NF-${\kappa}B$.

Development of a locomotive mechanism for the capsule type endoscopes will largely enhance the ability to diagnose disease of digestive organs. In connection with it, most of the researches have focused on an installable locomotive mechanism in the capsule. In this paper, it is introduced that the movement of a capsule type endoscope in digestive organ can be manipulated by magnetic force produced outside human body. Since the magnetic force is provided by permanent magnets, no additional power supply to the capsule is required. Using a robotic manipulator for locating the external magnet, the capsule motion control system can cover the whole human digestive organs. This study is particularly concentrated on dither motion effect to improve the mobility of capsule type endoscope. It was experimentally found out that the friction coefficient between the capsule and digestive organ can be remarkably reduced by superposing yawing or rolling dither motion on the translatory motion. In this paper, the experimental results obtained while the direction, amplitude and frequency of sinusoidal dither motion were changed are reported.

Progressive familial intrahepatic cholestasis type 3 (PFIC3) is an autosomal recessive disorder of cholestasis of hepatocellular origin, typically seen in infancy or childhood caused by a defect in the ABCB4 located on chromosome 7. Here we report on an older patient, aged 15, who presented with biochemical testing that led to an initial consideration of a diagnosis of Wilson disease (WD) resulting in a delayed diagnosis of PFIC3. Diagnosis of PFIC3 was later confirmed by molecular studies that identified novel mutations in the ABCB4 gene. Cholestasis due to PFIC3 can cause elevated hepatic copper and increased urine copper excretion that overlap with current diagnostic criteria for WD. Molecular diagnostics are very useful for establishing the diagnosis of PFIC3. Ursodeoxycholic acid ameliorates cholestasis in PFIC3, and may help mediate a reduction in hepatic copper content in response to treatment.

Among several diseases of calves, diarrhea is the most prevalent disease and has been a major cause of economic loss to the cattle industry. The main etiologic agents of diarrhea in calves are bacteria, viruses, and protozoa, but non-infectious factors including foreign bodies obstruction in the digestive system also focused as the cause of calf diarrhea in the recent days. Because there is still limited information for foreign body-related diarrhea in calves, especially in Hanwoo, the present retrospective study reviewed the medical records for diarrheic calves with foreign body in the digestive system (n=32). The morbidity was determined as 3.03% and more than half of them presented the acidosis, hyponatremia, and azotemia. The mortality in laparotomy-operated calves to remove foreign bodies or in non-operated ones was 28% or 85.7%, respectively, implied the importance of aggressive decision for laparotomy when the foreign bodies were determined in the digestive system in diarrheic calves. During laparotomy, trichobezoars (hair balls) and hays were the main foreign bodies and prevalently placed in the abomasum. In the trials to predict prognosis by several clinical factors, the time for laparotomy over 2 days after first diagnosis, acidosis, and foreign body in the abomasum were highly associated with mortality. Therefore, we believe that prompt surgical procedure (laparotomy) is necessary upon obstruction in the digestive system by foreign bodies is tentatively diagnosed in the diarrheic calf. In addition, when differential diagnosis list is made, foreign body-related diarrhea is necessary to be included in case of diarrheic calf.

Cancer cachexia는 지방조직과 근육계 조직의 손실에 따른 체중의 현격한 감소를 특징으로 하고 있어 궁극적으로는 암 치료제에 대한 반응을 낮출 뿐만 아니라, 삶의 양은 물론 질도 낮추게 되는 시급히 해결되어야 하는 미충족 의료수요 중의 하나이다. 아직까지 임상에서는 수많은 노략에도 불구하고 일부 완화시킬 수 있는 약제가 있기는 하나, 전반적으로 해결이 가능한 약제나 치료 방법이 아직은 없는 실정이다. 그러므로 이를 해결할 수 있는 방법으로 동물모델이 필요한 질환이라 하겠다. 이러한 배경하에 연구자 등은 우선 동물모델을 수립하고 이를 기반으로 적절한 치료제를 개발하기 목적으로 본 연구에서는 C26 대장 선암 세포를 이용한 Cancer cachexia 동물모델을 수립하여 이 모델에서의 변화를 소개함으로써 향후 더 진보된 치료제 개발이나 병태생리를 연구하는데 도움을 주고자 본 연구를 시행하여 다음과 같은 결과를 얻을 수 있었다. C26 adenocarcinoma를 대퇴부 주입 후 시간 경과에 따라 몸무게의 변화가 현저하여 2주 이후에 유의한 몸무게의 감소, 식욕부진, 활동감소가 관찰되었고, 이때의 혈청 Cytokine 및 이를 조절하는 여러가지 전사인자의 변화가 선행되었고, 현저한 근육계의 근감소가 관찰되었으며, 실험동물은 3주에 40%가 사망하는 변화를 보였다. 연구자 등은 본 동물모델은 향후 새로운 치료약제 개발이나 Cancer cachexia 병태생리 연구에 매우 도움이 되는 수립하기 간편하며, 기저 분자생물학적 변화를 관찰할 수 있는 우수한 Cancer cachexia 모델이라 결론지을 수 있었다.

The Purpose of this study was to collect statistics of pediatric problems, and so to investigate the new effective oriental medicine treatments in pediatric disease and its clinical applicability. The Study was composed of 698 new patient who had been treated at the pediatric unit in th Dong Sea Oriental Medical Hospital for 1 year, from 1 September 2001 to 31 October 2002, and aged between 0 and 18 years. The Chief complaints and their care-givers. Result: 1. In the study, male children are 403 and female children are 295. So the sex ratio between male and female is 1.37 : 1. 2. In age distribution, 0-3 years : 317(45.4%), 4-6 years : 148(21.2%). 7-9 years 98(14.0%), 10-12 years: 66(9.5%), 13-15 years : 40(5.7%), 16-18 years 29(4.2%). 3. The chief complaint according to systemic division was Respiratory diseases covers 30.1%, Digestive diseases covers 20.8%, Physique diseases covers 10.6%. 4. The Respiratory diseases tended to increase in autumn and appeared mostly in the age group between 0 and 9 years. The Digestive diseases increase in summer and appeared mostly in the age group between 10 and 12 years. The physique diseases increase in winter and appeared mostly in he age group between 13 and 18 years. 5. Most of patient came to the hospital from diseases such as common cold, weakness, dyspepsia, atopic dermatitis, rhinitis, take a easy cold, short stature, sweating, Bell's palsy, abdominal pain, etc. Conclusion : 1. The chief complaint In pediatric diseases that needed an oriental medical treatment was mainly the disease that tends to take long time and the weakness, and appeared frequency in respiratory and digestive disease. 2. The oriental medical treatment was still preferred as a way to improve the weakness by patients, rather than a way to overcome their disease. in particular, the study shows that the oriental medical treatment should be emphasized in terms of preventing the disease. 3. The new disease, which were developed with change of human life and environment, should be investigated as a new fie of oriental medical treatment.
