  • A dead dove was found on the road and submitted for diagnosis. The bird was severely emaciated, with deformation in its facial area. Grossly, white coalescing nodules were seen on the cut surface of the nasal cavity. Histopathologically, epithelial cells of the upper respiratory tract were markedly proliferated, with ballooning degeneration, down growth of the rete ridge, and large eosinophilic intracytoplasmic inclusion bodies. Parakeratotic hyperkeratosis and focal necrotic focus was present in the proliferative area. The facial bones showed partial bone resorption. Transmission electron microscopy revealed numerous viral particles in epithelial cells with dumbbell-shaped bodies, consistent with poxvirus.

  • Sachungwhan reduced hepatotoxicity induced by carbon tetrachloride($CCl_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase(ALP), blood urea nitrogen(BUN), creatinine(CRE), total cholesterol(TCHO), triglyceride(TG), low density lipoprotein cholesterol(LDL-CHO), high density lipoprotein cholesterol(HDL-CHO), total protein(TP), albumin(ALB) and total bilirubin(BIL) in serum. Hepatic parameters monitored were levels of cholesterol(CHO), triglyceride(TG), malondialdehyde(MDA), content of cytochrome P450(CYP), level of glutathione(GSH), and activities of NADPH-CYP reductase, superoxide dismutase(SOD), catalase(CAT), glutathione S-transferase(GST), glutathione reductase(GR), glutathione peroxidase(GPx). The histopathological examination showed that the treatment of Sachungwhan relieved the ballooning degeneration of hepatocytes which had been generated by $CCl_4$. The results suggested that hepatoprotective effects of Sachungwhan possibly are due to their promising antioxidative activity.

  • Three components, fraxetin-8-glucoside, esculetin-6-glucoside and mannitol, were isolated from the stem bark of Fraxinus chiisanensis var. stenophylla, F. japonica var. intermedia and F. densata. The MeOH extract of the cortex of F. densata had the antiinflammatory activity on the carrageenin-induced paw edema in rat. The MeOH extracts of the cortex of all three Fraxinus spp. have the potent analgesic activity on the HOAc-induced writhing syndrome in mouse and the hepatoprotective activity on the $CCl_4-induced$ fatty liver in rat: protection of ballooning formation and inhibition of sGPT and sGOT increased by $CCl_4$.

  • 최근 스마트 TV는 멀티코어, 3D가속, 고속 네트워크 및 다양한 인터페이스 지원 등으로 인하여 성능이 향상되었다. 향후 스마트 TV는 씬-클라이언트인 이기종 단말기에게 홈 클라우드 서비스를 제공할 것으로 기대되고 있다. 홈 클라우드로서의 스마트 TV는 단말기 간의 보안과 다양한 서비스를 제공하기 위해 가상화가 기술이 필요하다. 그러나 가상화 환경에서의 스마트 TV는 다중의 가상 머신이 실행될 경우 메모리 부족으로 인해 스왑-아웃 문제를 유발한다. 본 논문에서는 스마트 TV의 메모리 사용 분석 및 ballooning을 통한 효율적인 호스트 메모리 관리의 필요성을 제시한다.

  • To investigate wall-thinning impact on axial load resistance of Zircaloy-4 cladding rods after a LOCA transient, axial tensile samples have been machined on as-received tubes with reduced thicknesses between 370 and 580 ㎛. After high temperature oxidation under steam at 1200 ℃ with measured ECR ranging from 10 to 18% and water quenching, machined samples were axially loaded until fracture. These tests were modeled using a fracture mechanics approach developed in a previous study. Fracture stresses are rather well predicted. However, the slightly lower fracture stress observed for wall-thinned samples is not anticipated by this modeling approach. The results from this study confirm that characterizing the axial load resistance using semi-integral tests including the creep and burst phases was the best option to obtain accurate axial strengths describing accurately the influence of wall-thinning at burst region.

  • It is important to choose which approaches should be used to correct the fracture if the operation is indication for surgery in patients with orbital floor fracture. Transorbital, transantral, and endonasal approaches are methods for correcting the orbital floor fracture. The approach needs to be considered the location of the fracture, the degree, the severity of the fracture, the least remaining patient's disability, and preference of the surgeon. We report a case of orbital floor fracture using transorbital approach and endonasal catheter ballooning to resolve the limitations of transorbital approach alone.

  • Three neonatal pigs from the same litter in a domestic farm were born with skin lesions. Grossly, multiple well-circumscribed, round papules distributed over the skin of the three piglets. Two piglets were submitted for a diagnosis of skin disease. Microscopically, epidermal hyperplasia with ballooning degeneration of stratum spinosum keratinocytes was observed. Some keratinocytes contained eosinophilic intracytoplasmic inclusions and a central nuclear vacuole and chromatin margination. Swinepox (SWP) virus was detected by polymerase chain reaction and nucleotide sequencing, and Staphylococcus hyicus was isolated in skin lesions. Based on the gross findings and laboratory results, these piglets were diagnosed with congenital SWP with a secondary staphylococcal infection.

  • High-fat diet (HFD)-fed ovariectomized (OVX) female mice were used as an animal model of obese postmenopausal women. We investigated the effects of ascorbic acid on the histological changes induced in the liver. Plasma alanine aminotransferase levels and liver weights were higher in mice fed an HFD for 18 weeks than in mice fed a low-fat diet, effects that were inhibited by ascorbic acid. Similarly, mice fed an ascorbic acid-supplemented HFD had less hepatic lipid accumulation than did mice fed an HFD alone. Moreover, administration of ascorbic acid reduced inflammatory cells, including mast cells and CD68-positive cells, and inflammatory foci in the liver and inhibited hepatocyte ballooning. Hepatic collagen levels were lower in ascorbic acid-treated versus non-treated mice. These results suggest that ascorbic acid inhibits hepatic steatosis, inflammation, and fibrosis in obese OVX mice. Thus, ascorbic acid intake may be useful for postmenopausal women with nonalcoholic fatty liver disease.

  • Objective : This study was carried out to investigate the effects of oral administration of Hyeungbangjihwang-tang (HBJHT) on the liver cirrhosis of rats induced by Carbon tetrachloride for 10 weeks. Method : The histopathological changes were observed. The HBJHT extracts were daily dosed at 50, 100 and 200mg/kg for 12 weeks. Results : Severe hepatocellular necrosis and ballooning, hyperplasia of connective tissue, subdued reduction of hepatic lobule, and hyperplasia of bile duct in portal triad were dramatically decreased in the HBJHT-treated group compared to that of the Carbon tetrachloride-treated control group in histopathological observation. The diameter of hepatic lobules was significantly enlarged in the HBJHT-treated group compared to that of the Carbon tetrachloride-treated control group, and the amounts of connective tissue, degenerative cells and bile ducts were significantly and dose-dependently decreased. Conclusion : It is concluded that HBJHT has a significant recovering effect on the liver of rats induced by carbon tetrachloride.

  • Purpose : The purpose of this study is to provide the basic data to improve pre-hospital phase emergency care for acute myocardial infarction (AMI) patients by analyzing AMI patients' clinical characteristics and emergency care situations. Methods : Data were collected through medical records of 385 AMI patients including ambulance records of 107 AMI patients transferred to the emergency medical center for three and a half years. Results : Regarding emergency care for AMI patients in pre-hospital phase, 47% of the care revealed moderate level or higher, and appropriateness of pre-hospital phase emergency care for cardiopulmonary complaints practiced by paramedics showed statistically significant improvement in recent years (p<.001). The time from onset of symptom to ballooning intervention by 119 emergency services was shorter than that in other cases. However, emergency care by paramedic was mainly basic life support. Conclusion : Since prognosis of AMI shows vast differences depending on prompt detection and medical intervention, cooperation between pre-hospital and in-hospital phase is highly required. 119 paramedics should be trained focusing on the accurate assessment and emergency care, and medical direction should be activated. In addition, regulation on 12-lead EKG, cardiac enzyme analysis, use of analgesics and thrombolytic agents should be legally implemented.
