국내산 참마를 스폰지 케이크 제조에 이용하고자 열풍건조와 냉동건조로 각각 가공된 두 가지 마가루를 케이크 배합비에 3, 5, 7%의 비율로 각각 첨가하여 케이크의 식품체계에 어떤 영향을 미치는지 알아보았다. 달걀 거품의 비중, 점도 및 안정성을 측정하고, 그에 따른 최종 케이크 품질을 물리적, 관능적 특성을 조사하였다. 이들의 결과에서 건조방법이 다른 두 종류의 마가루는 모두 달걀의 거품 형성능에는 영향을 미치지 않았으며, 달걀 거품의 점도는 FDYP 첨가구가 대조구와 HDYP첨가구보다 유의적으로 높아 달걀거품 안정성에 있어서 매우 효과적인 것으로 나타났다. 그러나 밀가루 투입 후 케이크 반죽 비중은 마가루 첨가로 증가하여 그에 따른 케이크 부피는 마 첨가율이 증가할수록 감소하였으며 그 감소폭은 FDYP 첨가 케이크에서 HDYP 첨가 케이크보다 크게 나타났다. Texture analyzer를 이용하여 조사한 마첨가 케이크의 조직감은 마 첨가 비율 증가에 따라 경도, 검성, 씹힘성이 증가하였으며, 그 경향은 HDYP보다 FDYP에서 현저하게 나타났다. 마의 건조방법이 스폰지 케이크 관능검사에 미치는 영향을 조사하기 위하여 부피와 외관이 비교적 양호한 HDYP 및 FDYP 5% 첨가구를 대조구와 함께 정량적 묘사분석을 실시한 결과, HDYP 첨가는 향미를 제외하고 모든 관능 특성에서 대조구와 유사하게 나타났으며, 반면에 FDYP첨가는 케이크의 crust color를 어둡게 하며 불균일한 기포와 비교적 단단한 조직감을 나타내었다. 마첨가로 케이크의 향미는 은은한 마향(yam flavor)이 증가하였고 본래 스폰지 케이크의 달걀비린내는 감소되었다. 스폰지 케이크 배합에는 FDYP 첨가보다 HDYP 첨가가 유리하며, 케이크의 부피, 단단한 정도와 내부구조 및 기공의 균일도를 고려한 HDYP와 FDYP의 최대첨가 수준은 각각 7%, 5%가 가능한 것으로 나타났다. This study investigated the quality characteristics of sponge cakes with addition of yam (Dioscorea) powders prepared by different drying methods, hot air (HDYP : hot air dried yam powder) and freeze drying (FDYP: freeze dried yam powder), using several physical and sensory examinations. For the foam forming ability and foam stability, the specific gravities of egg foams containing 5% yam powders were measured by drainage using funnels for 8 hrs. The results showed that HDYP and FDYP did not affect the foam forming ability but FDYP increased foam stability due to increased viscosity. When the strength of 8% gels composed of wheat starch and HDYP/FDYP was measured to predict the setting of cake structure, the strengths of starch gels containing yam powders were higher than those of control without yam powders. The volume of sponge cake containing 5% HDYP increased whereas those containing FDYP decreased at the levels of 5, 7%. From the texture profile analysis data, hardness, gumminess and chewiness of cakes containing yam powders increased. The color of cake crust and crumb became darker as the amount of yam powders increased. The results of sensory evaluation by QDA (quantitative descriptive analysis) to compare two different drying methods showed that appearance and texture of cakes containing 5% HDYP were closer to those of control than cakes containing 5% FDYP but overall acceptability of sponge cakes containing yams were comparable to the control cakes regardless of drying methods. The addition of yam powders to sponge cakes increased yam flavor and decreased egg smell. Therefore, it can be suggested that HDYP and FDYP can be added to the sponge cake formula up to 7% and 5%, respectively.

N/A Backgound/Aims: The effectiveness of magnetic resonance cholangiography(MRC) for diagnosing obstructive jaundice, as a noninvasive alternative to direct cholangiography(endoscopic retrograde cholangiopancreatpgraphy; ERCP or percutaneous transhepatic cholangiography;PTC) is studied. The goal of the study is to evaluated the level of reliability and efficacy of MRC for identifying the obstruciton site and the cause of it. Methods: Thirty two consecutive patients with obstructive jaundice are included in the study. Non-breath-hold, heavily T2-weighted, fast spin echo MRC is used to obtain; 2D-axial, coronal, and 3D-images with maximal intensity projection protocol. We evaluated all patients retrospectively by ERCP, PTC, or operation to compare the results. Results: The causes of obstruction are 13 common bile duct cancer cases, 2 pancreatic cancer cases, 8 extrahepatic duct stone cases, 3 intrahepatic duct stone cases, and 3 intra and extrahepatic duct stone cases. The level of obstruction is correctly diagnosed with MRC for 100% of common bile duct cancer and pancreatic cancer cases, 90.9% of extrahepatic duct stone cases, and 66.7% of intrahepatic duct stone cases. MRC revealed the correct causes of obstrcution for 80% of common bile duct cancer and pancreatic cancer, 81.8% of extrahepatic duct stone, and 50% of intrahepatic duct stone. Conclusions: MRC provided a accurate level of obstruction and diagnosis for common bile duct cancer, pancreatic cancer, and extrahepatic duct stone but not for intrahepatic bile duct stone. Therefore, MRC may be used with caution as a noninvasive altemative to invasive cholangiography, if not as a cornplete replacement of it. (Korean J Gastroenterol 1996; 2S:690 - 696)

N/A 'A'idespread enthusiasm for laparoscopic cholecystectomy(LC) has raised new and inter- esting questions for the endoscopic retrograde cholangiopancraetography(ERCP) manage- ment of duct sotnes. Few laparoscopic surgeons currently explore the bile duct at cholecystectomy, which has focused attention on the role ERCP in the diagnosis and treatment of duct stones. We assessed the use of ERCP before and after LC at our hos- pital. Indications for ERCP depend on the likehood of duct patho)ogy,'clinical, biochemical and radiologic predictive factors are established. Prediction of duct stones and indication for ERCP before LC were 3 groups,'historic factors(recent jandice, cholangitis, pancreati- tis) 25%(29/116), abnormality of liver function tests 45%(53/116), and bile duct size<as measured at ultrasonography) 37%(43/116) in this study. ERCP is highly efficient in the management of patients with symptoms after LC in order to exclude, diagnose, and treat complications such as retained stones, cystic duct leaks, and strictures. Overall, ERCP technique are used in about 12.2% patients before and after LC of this study. The fundamental question is whether t.he combination(LC and endoscopic duct ex- ploration) is a better option for the patients than old fasioned operative intervention. Each surgical and endoscopic team will need to develop and test algorithms in the hope of minimizing the risk of unfortunate scenarios.(Korean J Gastroenterol 1994; 26: 541 548)

역행성 췌담관 조영술에 있어서 유두주위 게실의 임상적 의의

이선영(Sun Young Yi),이한주(Han Chu Lee),정혜경(Hye Kyoung Jung) 대한내과학회 1998 대한내과학회지 Vol.55 No.5

N/A Objectives: Diverticula on the second part of the duodenum have a 1-5% incidence in barium studies reports. They have been associated to: choledocholithiasis, biliary dysfunction, acute pancreatitis, diverticulitis, duodencolic fistula, bleeding, malabsorption, and bowel obstruction. With forward viewing endoscope diverticula are not easy to see but with side viewing scope are commonly seen and widely accepted as a cause of difficult cannulation and/or sphinterotomy. The purpose of this study is to determine the incidence of periampullary diverticula and to see whether our results are in accordance wtih above statements included in difficult cannulation and/or sphincterotomy at endoscopic retropgrade cholangiography(ERCP) in retrospectively examine our own series. Also to examine their association with biliary and pancreatic diease. Patients and Methods: Three hundred and thirty one consecutive ERCP reports were reviewed with special reference to the following: sex, age, presence of duodenal diverticula, difficulty of cannulation and/or sphinterotomy. Results: Seventy-nine patients(24%) had one or mare periampullary diverticula Age and sex made no difference. Thirty-two (10.3%) had a difficult or unsuccessful cannulation and only five of those patients(1.6%) had periampullary diverticulum(p<0.001). But the failure rate of large sphincterotomy was more common in patient with periampullary diverticum(73.5%) than without diverticulum(24.6%) (p<0.001). The disease of the patients who had diverticulum, gallstone is the most frequent incidence(77.2%). Diverticulum was more frequently found in choledocholithiasis patients(45.3%) than studied patients(24%). Conclusion: Periampullary diverticula are a common finding during ERCP and less likely to cause a unsuccessful cannulation, but the cause of unsuccessful sphincteromy.

점질물을 다량 함유하고 있으며 생리효능이 높다고 알려진 마(Yam : Dioscorea)의 첨가가 이스트 발효빵 품질에 미치는 효과를 알아보고자 건조방법을 달리한 열풍건조마가루와(hot air-dried yam powder : HDYP)와 동결건조마가루 (freeze-dried yam powder : FDYP)를 3, 5, 7% 수준으로 수입밀과 우리밀을 이용한 이스트 발효빵 배합비에 첨가하여 빵반죽과 최종빵의 기계적 특성 및 관능적 특성을 살펴보았다. 마 첨가 빵반죽의 특성은 Texture analyzer를 통해 반죽의 stickiness를 측정하고 5점 척도의 주관적인 작업 적성(handling property)을 평가하였다. 마 첨가 빵반죽의 적정수분흡수율은 수입밀에 비하여 우리밀이 4~8% 낮으며 마첨가비율이 높을수록 증가하였다. 반죽의 stickiness는 우리밀반죽이 수입밀반죽보다 높게 나타났으며 마첨가에 의한 반죽stickiness 변화는 수입밀에서 유의적인 증가를 보였으나 반죽작업이 어려운 정도는 아니었다. 우리밀 반죽의 FDYP 첨가구는 stickiness의 적은 감소에도 불구하고 반죽작업적성은 가장 열등하게 나타났다. 우리밀은 수입밀에 비하여 낮은 oven spring을 보였으며, 특히 FDYP 첨가 비율이 증가할수록 oven spring이 큰 폭으로 감소하였다. 마첨가 수입밀빵의 최종 부피는 FDYP 7% 첨가로 다소 감소하였으나, 다른 모든 처리구에서는 대조구와 유사하였고, 우리밀빵은 전반적으로 FDYP 첨가구가 HDYP 첨가구보다 빵부피면에서 열등한 것으로 나타났다. 빵의 기계적 조직감은 수입밀빵보다 우리밀빵이 단단하고 부착성이 높았으며 마첨가로 조직감변화가 우리밀에서 다소 크게 나타나 경도, 씹힘성, 응집성, 검성이 증가하였다. 마 첨가에 따라 빵의 crumb색은 어두워졌으며, 반죽적성, 빵부피 및 bread scoring평가결과를 기준으로 선택된 각각 5% 마첨가 수입밀빵과 3% 마첨가 우리밀빵에 대한 관능검사에서 마첨가의 효과가 수입밀보다 우리밀에서 뚜렷하게 나타나 빵의 외관이 향상되고, 우리밀 특유의 곡물향이 감소되며, 맛과 조직감이 향상되어 기호 측면에서 우리 밀빵의 품질향상 효과가 크게 나타났다. 그러므로 본 연구결과에 의하면 종합적 제빵적성면에서 이스트 발효빵에 마가루 첨가는 HDYP 5%와 FDYP 3%가 가능하다고 할 수 있다. This study investigated the quality characteristics of yeast breads with addition of hot air-dried yam powder (HDYP) and freeze-dried yam powder (FDYP), using several physical and sensory examinations. Breads were made of imported wheat flour (IWF) or Korean wheat flour (KWF). HDPY and FDYP were added to the bread formula at three levels of 3, 5, and 7%. The addition of yam powders required an increase of water absorption. As the addition of HDYP/FDYP increased, IWF dough stickiness increased and thus handling property became inferior to the control. Especially, handling property of KWF bread dough containing FDYP was most poor among the dough samples. With HDYP/FDYP, final volumes of bread made from IWF were similar to the control at all added levels except for 7% FDYP. In bread made of KWF, loaf volumes were similar to the control when 3~5% HDYPs were added whereas loaf volumes decreased significantly as the amount of added FDYP increased, indicating volume depressing effect. In bread scoring, texture scores increased when yam powders were added using IWF and KWF. Especially, The grain scores of KWF bread also increased with HDYP. TPA data showed that hardness, chewiness, cohesiveness and guminess of KWF bread increased as the amounts of yam powders increased. The “L” value of IWF bread crumb decreased with the addition of yam powders. From sensory evaluation using acceptability scores, the results gave us that appearance, grain, texture, flavor, taste and overall acceptability of KWF bread could be more improved with the addition of yam powders than those of IWF bread.

N/A Objectives: Gastroesophageal reflux disease (GERD) is used to describe any symptomatic clinical condition or histopathologic alteration resultant from episode of gastroesophageal reflux; reflux esophagitis describes a condition experienced by subset of GERD patients with histopathologically demonstrable changes in the esophageal mucosa. GERD is widely reported to be one of the most prevalent clinical condition affecting the gastrointestinal tract, the figures on its incidence and prevalence was not studied in Korea, Therefore we carried out this study to determine the prevalence of reflux esophagitis, in related with symptom, smoking, drugs, and overweight among general health screening people. Method: 2,795 cases which were visited at general health screening center of Asan medical center during 5 month-period from April, 1993 to August, 1993 were surveyed by esophagogastroscopy. We devided patients ioto reflux esophagitis by Savary-Miller stage. We assessed the prevalence of reflux esophagitis endoscopically and sex and age related prevalence, symptom, associated disease, smoking, drug, and overweight related esophagitis. Result: We expierenced 66 cases of reflux esophagitis in 2,795 cases examined (63 cases of stage I, 3 cases of stage II). Total age adjusted prevalence in 2.74% (95% CI 1.98~2.87). In sex-adjusted prevalence, male vs female prevalence is 32 to 1, so there was significantly higher prevalence of male than female. Asymptmatic reflux esophagitis case were 48 cases (72.7%). Having associated disease and ingested drug were not related with the prevalence of reflux esophagitis (p >0.05). Reflux esophagitis patients of smoking were significantly higher than non-smoking (p<0.01). Also, reflux esophagitis patients of overweight were significantly higher than ideal or underweight (p<0.001). Conclusion : Age adjusted prevalence of reflux esophagitis in general health screening people is speculated as 2.74%. And the most patient of reflux esophagitis is asymptomatic. The smoking and overweight have significantly related with reflux esophagitis.
