고사리뿌리 전분의 이화학적인 특성연구의 일환으로 실시된 물리적 특성시험 결과는 다음과 같다. 전분입자의 미구조의 결합력을 보기 위한 흡수도, 팽운력, 용해도 시험결과 감자전분이나 타피오카전분보다 강한 결합을 하고 있으며 곡류전분보다는 약하며 팽윤력이 single-stage pattern을 이루고 있었다. 가열에 의한 전분입자의 복굴절성 상실, α-아밀라아제에 의한 소화성 및 X-선 회절둥으로 전분의 호화과정을 살펴본 결과 55-60℃에서 호화가 시작되고 60~70℃에서는 95%이상 호화되었다. 또한 3~6%전분용액의 가열에 따른 점도변화를 amyl-ograph를 사용하여 실험한 결과 pasting temperature 62~68℃, 최고점도 80~840BU, 50℃로 냉각후의 점도는 110~555BU였다. 따라서 다른 전분에 비해서 점도가 낮으나 setback이 현저히 느렸다. 수분함량 50%의 전분겔의 경도는 팥 전분보다는 약하고 감자나 밀전분에 비해서는 현저히 높았다. 전분겔의 저장중 노화속도는 밀 전분보다는 느리고 파지오카 전분보다는 빨랐다. 고사리뿌리 전분은 팥 전분겔특성에 큰 변화를 주지않지만 노화를 억제하였고 밀 전분겔에 첨가시에는 겔의 경도가 저하되어 부드러워지는 경향을 보였다. The gelatinization phenomena of bracken root starch were examined by means of the loss of birefringence, degree of digestibility by amylase and X-ray diffraction. These results indicated that gelatinization temperature of the starch was 55∼60℃ and over 95% of starch were gelatinized at the temperature between 60 and 70℃. The swelling power of the bracken root starch was much less steeper than that of potato or tapioca starch. Amylograph data on the various starch concentrations showed the pasting temperature of 62∼68℃, peak height of 80∼840 Brabender unit (BU) and peak after cooling to 50℃ of 110∼555 BU. According to the information obtained from amylograph data, the bracken root starch showed low set back. The rate of retrogradation of the starch as tested by Texturometer was slower and faster than potato and tapioca starches, respectively.

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.

Anisakiasis refers to parasitic infestation by nematode larvae that belongs to the subfamily Anisakinae, and this condition is seen in people who eat inadequately prepared or raw salt-water fish. While gastric anisakiasis is commonly diagnosed by endoscopic technique, intestinal anisakiasis is rare because it is less common and the clinical and radiologic features are poorly understood. The authors report a case of human anisakiasis involving the ileocecal valve in 62-year-old man who had the history of eating raw cuttlefish.

저자들은 급성 림프구성 백혈병 환자에서 항암치료 후 호중구감소증이 지속되는 상태에서 침습성 아스페르길루스증의 드문 형태인 치명적인 아스페르길루스 기관기관지염을 경험하고 문헌고찰과 함께 증례를 보고하는 바이다. Tracheobronchial aspergillosis is an uncommon clinical form of invasive aspergillosis, particularly found in patients with AIDS and in lung transplant recipients than in other immunocompromised patients. The rapidity of the disease progression can result in fatal airway obstruction in a short period of time that the patient may need emergency tracheostomy without knowing the cause of the obstruction. We describe a case of fatal tracheobronchial aspergillosis which developed in a 43-year-old female patient with acute lymphoblastic leukemia. Dyspnea and stridor developed on the 20th day after 2nd consolidation chemotherapy, which was during the prolonged neutropenic period. Airway narrowing was observed on the computed tomograph scan of neck and emergency tracheostomy was performed. Infiltration with aspergillus hyphae was found in the tracheal ring and bronchial mucosa. Despite the use of amphotericin B, the patient died of bleeding and airway obstruction.

This paper concerns the static, dynamic and thermal characteristics analysis of a high-speed spindle system for horizontal machining centers with φ45mm × 50,000rpm. The spindle system is designed based on the angular contact ceramic ball bearings, built-in motor, oil-air lubrication method and oil jacket cooling method. The structural and thermal analysis models of spindle system are constructed by the finite element method. The static and dynamic characteristics are estimated based on the static deformation, modal parameter, mode shape and frequency response function, and the thermal characteristics are estimated based on the temperature rise, temperature distribution and thermal deformation. The analysis results illustrate that the designed spindle system has excellent structural and thermal stabilities.

Gastric angiodysplasia is vascular ectasia in mucosa and submucosa of the gastric wall. It is an uncommon cause of upper gastrointesinal hemorrhage that may occur in the stomach or duodenum. There are many kinds of endoscopic treatments, such as argon plasma coagulation, electrocoagulation, heat probe, and submucosal injection of hypertonic saline mixed with epinephrine for gastric angiodysplasia. However, these treatment methods are associated with high rate of rebleeding. In order to avoid the recurrence, endoscopic band ligation has recently been used as an alternative method for endoscopic treatment of gastric angiodysplasia. We encountered a case of gastric angiodysplasia that presented with overt bleeding and anemia, and was successfully treated with endoscopic band ligation.

Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

This study explores the potential of improving the physical properties of poly(trimethylene terephthalate) (PTT) by inducing thermotropic liquid crystalline polymers. The TLCP was synthesized by polycondensation reaction of terephthaloyl chloride with corresponding diols. The TLCP used was copolymers containing random PTT groups on the polymer backbone. The PTT moieties were used to increse compatibility between the PTT and the TLCP. The TLCP showed the nematic phase above those melting temperature(T_m) The TLCP seems to act as plasticizers and nucleating agents in the matrix polymers Liquid crystalline phase did not reaveal any significant macrophase separation and thermal degradaton under the temperature of processing condition.

Objective: We investigated effects of serum serotonin and interleukin 18 levels on suicidal ideation (SI) at acute and chronic phases of acute coronary syndrome (ACS). Methods: Recent-onset 969 ACS patients were evaluated for serum serotonin and interleukin 18 levels; and SI by the “suicidal thoughts” item of the Montgomery–Åsberg Depression Rating Scale. After 1-year, 711 patients were re-evaluated for SI. Logistic regression models were used adjustment for potential covariates. Results: Associations between serum interleukin 18 and SI at both phases were significant only in the lower serotonin group. Conclusion: By evaluating serum serotonin and interleukin 18 levels, the clinical prediction of SI of ACS may be improved.
