In this study, we report the characteristics of three Kinds of Radar Exploration Systems, which are used in geological cavity detection, for effective use. The systems are RAMAC, PEMSS and KAIST CW. We repeated measurements each system for same geological model. The AMAC System has a unique capability in finding fracture zones from the reflected waves, and represents the cavity as a hyperbola because the cavity responds as a point source. In the PEMSS systems the relative velocity and attenuation of the electromagnetic wave which varies by geological medium represents geological structures. The main merit of the PEMSS system is cavity localization. The location of the cavity is determined the depths of cavity signals in each offset data. The KAIST CW system also detects a cavity from the attenuation pattern of continuous waves. This uses the phenomenon of 180'phase change of the wave when it propagates the cavity, producing the high attenuation at that point. Our study shows that the RAMAC is suitable in cavity scanning, the PEMSS is adaptive in precise geology exploration, and KAIST CW is best in cavity detection.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherapy seems a logical choice for cancer chemotherapy. In this study, Mitomycin C (MMC)-activated charcoal (CH)-alginate (ALG) beads were prepared by the mixtures of CH particles adsorbed with MMC as an anti-cancer drug and aqueous alginate solution. The alginate is recognized as biodegradable, nontoxic, and biocompatible. The release of MMC from the beads in 0.1 M Tris buffer was stable and continuous until about 1 week. The MMC-CH-ALG beads can be applied in the peritoneal cavity for intraperitoneal chemotherapy since they provide a good adhesiveness on the tissue and controlled release pattern of the drugs.

<P>With recent progress in treatment modalities, mortality from upper gastrointestinal (UGI) bleeding has decreased appreciably. The aim of this study was to establish how UGI bleeds are managed in Korean patients with cirrhosis and to evaluate treatment outcomes. A total of 479 episodes of acute UGI bleeding in 464 patients with cirrhosis were included during a six-month period at nine tertiary medical centers. Treatment outcomes were assessed by failure to control bleeding, rebleeding and mortality. The source of bleeding was esophagogastric varices in 77.7% of patients, nonvariceal lesions in 15.9%, and undefined in 6.5%. For control of bleeding, endoscopic and pharmacologic treatments were used in 74.7% and 81.9% of patients, respectively. Variceal ligation was a major technique for endoscopic treatment (90%), and terlipressin and somatostatin were the main pharmacologic agents used (96.4%). Initial hemostasis was achieved in 86.8% of cases, but rebleeding occurred in 3.8% and 16.8% of cases within five days and six weeks of hemorrhage, respectively. Five-day and six-week mortality were 11.3% and 25.9%, respectively. Survival of patients with variceal bleeding seems to be remarkably improved than previous reports, which may suggest the advances in hemostatic methods for control of variceal hemorrhage.</P>

Chronic profuse vaginal discharge could be related to lobular endocervical glandular hyperplasia (LEGH) or adenoma malignum: Analysis of fourteen cases

Lobular endocervical glandular hyperplasia (LEGH) is a benign lesion characterized by non-invasive proliferation of endocervical glandular cells. Adenoma malignum, known as minimal deviation adenocarcinoma of the uterine cervix is an extremely well-differentiated mucinous adenocarcinoma. The objective of this study was to look for the characteristic findings in LEGH and the major consideration in the differential diagnosis with adenoma malignum. We carried out a retrospective analysis of cases treated at our hospital from 2002 to 2012. All cases of LEGH and adenama malignum presented profuse watery vaginal discharge, and transvaginal ultrasonography and MRI findings showed multicystic lesion. Pap smear was usually normal and conization was the main diagnostic method, however conization was not appropriate in cases of deep and highly located lesion. In these cases, we performed laparoscopic excisional biopsy or hysteroscopic biopsy with frozen section for differential diagnosis of adenoma malignum from LEGH. LEGH, LEGH with adenocarcinoma in situ, and adenoma malignum present similar clinical findings. Due to apparent difference in the treatment, an accurate preoperative differential diagnosis is necessary. Conization is the diagnostic method of choice. But, in cases of deep and highly located lesion or where conization could not include the exact lesion, further evaluation such as laparoscopic excisional biopsy or hysteroscopic biopsy with frozen section instead of conization only shoule be considered.

The study investigated the effects of adding bovine plasma protein(PP) hydrolysates on the quality properties of cooked pork patties. Pork patties were prepared as follows: manufactured with pork back-fat(control); replacement of back-fat with 40% olive oil(T1), 40% olive oil and 2% PP hydrolysates(T2), and 40% olive oil and 4% PP hydrolysates(T3). The olive oil modified the fatty acid profiles of the pork patties by lowering the saturated fatty acids(SFAs) percentage. Olive oil and 4% PP hydrolysates addition reduced the level of 2-thiobarbituric acid-reactive substance(TBARS) values in pork patties, compared to the controls. Furthermore, the pork patties with added PP hydrolysates had higher pH values than the control. All samples containing olive oil and PP hydrolysates had increased levels of DPPH radical scavenging activity. In particular, added PP hydrolysates were more effective in increasing antioxidant activity than were the other treatments. Therefore, PP hydrolysates could be used as a natural antioxidative in cooked pork patties.

수막암종증은 암세포가 뇌수막에 침윤한 상태로 정의하는데 자기공명영상이 진단방법으로 쓰이기 전까지 진단이 용이하지 않았다. 또한 전립선암 환자에서 수막암종증이 생긴 경우는 매우 희귀하여 증례보고 형식으로 소수에서 보고 되고 있는 실정이다. 내원 11년 전 전립선암으로 근치적 전립선 절제술을 받고 내원 4년 전 골전이로 항암치료를 받은 병력이 있는 환자로 경련을 주소로 내원하여 시행한 반복적인 뇌척수액 검사에서 세포진을 발견하지 못했지만 뇌척수 액 전립선 특이항원 양성소견과 뇌 자기공명영상 소견으로 수막암종증을 진단하고 조직검사를 통해 확진하여 적극적인 치료로 생명연장을 할 수 있었던 사례를 경험하였기에 문헌 고찰과 함께 보고한다. Meningeal carcinomatosis in patients with prostate cancer is very rare. Recently, we experienced a case of meningeal carcinomatosis in a patient with prostate cancer. He had undergone a radical prostatectomy 11 years before presentation and had undergone chemotherapy 4 years before presentation due to bone metastases. This time, he visited the emergency department because of a seizure. Although cerebrospinal fluid (CSF) examinations did not reveal malignant cells, we diagnosed meningeal carcinomatosis based on positive CSF prostate-specific antigen and magnetic resonance imaging (MRI) findings. The diagnosis was confirmed pathologically. We treated the patient with whole brain radiotherapy and intrathecal chemotherapy. We report a case of prostate cancer with meningeal carcinomatosis with a literature review. (Korean J Med 2011;81:262-265)

목적: PEG 용액은 안전하고 정결 효과가 우수하여 현재 임상 에서 대장내시경 전처치제로 가장 널리 사용되고 있지만, 특 유의 짠맛으로 환자의 순응도가 낮다는 제한점이 있다. 이번 연구는 이러한 단점을 보완하기 위해 표준 PEG 용액에 설탕 을 첨가하여 복용하도록 한 후 대장 정결 효과 및 환자 순응도 를 표준 PEG 용액을 복용한 군과 비교 분석하고자 하였다. 대상 및 방법: 2012년 1월부터 6월까지 강릉아산병원 소화기 내과에서 대장내시경을 시행받은 총 100명의 환자들에 대해 무작위 전향적 대조 연구를 진행하였다. 대장 정결은 표준 PEG 용액 4L 또는 설탕을 첨가한 PEG 용액 4 L 중 한 가지 로 무작위 배정하였다. 시술자 설문지를 통해 대장 정결도와 내시경의의 검사만족도를 조사하였고, 환자 설문지를 통해 순 응도를 조사하였다. 결과: 두 군 사이에 대장 정결도(4.2±2.0 vs. 4.1±1.5, p=0.783)와 내시경의의 검사만족도(8.2±1.8 vs. 8.5±1.3, p=0.253)는 유의한 차이가 없었으나 환자의 역겨움의 정도 는 설탕첨가 PEG군이 3.9±2.9로 표준 PEG군 6.4±2.3과 비교하여 볼 때 역겨움의 정도가 낮았으며(p<0.05), 같은 방 법으로 재검사하겠다는 응답도 설탕첨가 PEG군이 2.3±0.7 로 표준 PEG군 2.0±0.6보다 높았다(p<0.05). 전처치제를 복용하면서 느낀 주관적 불편감은 두 군 사이에 유의한 차이 가 없었다. 결론: 설탕을 첨가한 PEG 용액은 효과적인 대장내시경 전처 치 방법이며 표준 PEG 용액을 복용할 때 짠맛으로 인해 복용 의 어려움을 호소하는 환자에게 좋은 대안이 될 수 있을 것으 로 기대된다. Background/Aims: Although polyethylene glycol (PEG) solution is commonly used for colonoscopic bowel preparation because of its safety and effectiveness, its salty taste decreases patient`s compliance. The aim of this study was to compare the sugared PEG solution with the standard PEG solution in regard to the quality of bowel preparation and patient`s compliance. Methods: From January through June in 2012, 100 patients who underwent colonoscopy in Gangneung Asan Hospital were prospectively enrolled. They were randomly assigned to receive either standard PEG solution or sugared PEG solution. The quality of bowel preparation was assessed by a doctor`s questionnaire and the patient`s compliance was assessed by a patient`s questionnaire. Results: There was no significant difference in the quality of bowel preparation (4.2±2.0 vs. 4.1±1.5, p=0.783), and endoscopist`s satisfaction score (8.2±1.8 vs. 8.5±1.3, p=0.253) between two groups. However, The degree of disgust was lower in the sugared PEG group than the standard PEG group (6.4±2.3 vs. 3.9±2.9, p=0.000). The willingness to repeat same regimen was higher in the sugared PEG group than the standard PEG group (2.0±0.6 vs. 2.3±0.7, p=0.004). There was no difference in side effects between two groups. Conclusions: The sugared PEG solution as a bowel preparation method revealed a higher patient`s compliance and was effective as the standard PEG solution. When the patient dislike the taste and saltness of the standard PEG solution, the sugared PEG solution will be good alternative method.

저자들은 무증상의 환자에서 시행한 검진 대장내시경에서 무경성 용종을 용종 절제술을 통해 제거하고 이에 대한 조직 검사에서 랑게르한스 세포 조직구의 침윤이 관찰되고 면역 화학 염색에서 S-100 protein과 CD1a 항원 양성 소견을 보여 랑게르한스 세포 조직구증을 진단하였으며 타장기 침범 소견이 없어 경과관찰 중인 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. A 56-year-old male underwent a screening colonoscopy. An 8-mm sessile polyp was removed from the descending colon using snare polypectomy. Histology showed Langerhans cells and eosinophil infiltration of the submucosa. Immunohistochemical stain-ing was positive for S-100 protein and CD1a antigen, which confirmed the diagnosis of Langerhans-cell histiocytosis. On further workup, there was no evidence of involvement of any other organs. Here, we report a very rare case of colonic Langerhans-cell his-tiocytosis presenting as an isolated polyp.
