  • The final preparation (MAF) size in infected root canals is still controversial. Nonetheless, recent studies demonstrated that larger apical preparation sizes produces a greater reduction in remaining bacteria and dentinal debris as compared to smaller apical preparation sizes. Therefore, clinicians should be practiced with treatment strategies guided by evidence-based information, especially in infected/failed root canals.

  • In group testing, the test unit consists of a group of individuals and each group is tested to classify units from a population as infected or non-infected or estimate the infection rate. If the test group is infected, one or more individuals in the group are presumed to be infected. It is assumed in group testing that classification of group as positive or negative is without error. But, the possibility of false negatives as a result of dilution effects happens often in practice, specially in many clinical researches. In this paper, dilution effect models in group testing are discussed and estimation methods of infection rate are proposed when a dilution effect exists.

  • This study was done to identify Newcastle disease virus(NDV) antigens in paraffin sections of various organs from experimentally NDV-infected chicken using peroxidase-antiperoxidase(PAP) technique. Sections were Incubated with rabbit anti-NDV polyclonal as first antibody, followed by incubation with goat anti-rabbit IgG conjugate and peroxidase anti-peroxidase ( PAP ). Positive reactions were often detected in the epithelim of trachea and in the lymphocyte of spleen at 24 hours after virus inoculation. The viral antigen was localized mainly in the cytoplasm of infected cells. The method approved to be highly specific for the indetification of NDV and allowed a precise localization of the viral antigens in infected cells.

  • Mycotic anuerysms are uncommon but it is a fulminant infectious process frequently resulting in rupture and death if not properly treated. Commonly known it as infected aneurysm caused by noncardiogenic bacteremia. We experienced a case of infected aneurysm of the abdominal aorta that ruptured into the retroperitoneum. A 57 year old man was admitted with lower back pain, fever and palpable mass. It was identified as an inf cted abdominal aneurysm with staphylococcal septicemia. He underwent resection of aneurysm and replacement with a prosthetic graft and prolonged postoperative organism-specific antibiotics therapy. He recovered well and discharged without complications postoperatively.

  • Infection of a median sternotomy incision may result in a large, unsightly,unstable,and potentially fatal wound. During the past 8 years, 5 consecutive patients [ 4 male and 1 female ] had repair of infected sternotomy wound. We describe our current preferred techniques and the results we have achieved with them. As soon as the sternal infection was shown, operative wound was opened and irrigated more than 4 times a day with 0.5% Betadine iodine solution until the exudate became clean with no growth of bacteria. Operation was performed in one-stage, which consisted of aggressive debridement of the infected bone and muscle transposition. Reconstruction was with one-side or both pectoralis flaps in all patients and rectus abdominis in 2 patients. There was no mortality or morbidity within 30 days postoperatively. We conclude that early aggressive debridement and muscle transposition remain the treatment of choice for most patients with infected median sternotomy wounds.

  • Current therapeutic strategies far anthrax have had no significant impact on anthrax mortality over the last several decades. This study used a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) discovery platform to generate protein expression profiles in search of overexpressed proteins in murine macrophage cells (RAW264.7) which infected with Bacillus anthracis spores as potentially novel molecular targets. Two differentially expressed proteins were identified in infected murine macrophage cells as Syndapin and CDC46, respectively. Syndapins are potential links between the cortical actin cytoskeleton and endocytosis. Other two proteins were identified from murine macrophage cells infected with avirulent spores as ITBG-2 (CD18) and HSPA5, respectively. These data demonstrate the feasibility of using a MALDI-TOF platform to generate protein expression profiles and identify potential molecular targets for anthrax therapeutics.

  • Treatment of infected mandibular fractures is confronted with various difficult problem, e.g. eradication of infection and osseous union even in the presence of devastating infection. To solve this problem various methods were proved including exteranal fixation, IMF and plating with some success. Author treated 3 cases of infected mandibular fractures with champy's miniplate. 1. Satisfactory union was obtained in 3 cases. 2. In One case, pus drainage continued even after internal fixation with miniplate, but it was easily controlled using proper antibiotic therapy & drainage. 3. In Case 3, autogenous bone graft was implanted into the infected fracture site to fill defect.

  • The purpose of this study was to evaluate the effect of a subsequent infection of porcine reproductive and respiratory syndrome(PRRS) virus to pigs with A. pleuropneumonia in pigs. Twenty three 7-weeks-old commercial pigs were infected with PRRS virus and/or A. pleuropneumoniae serotype 5 intratracheally. Feed conversion, clincal signs, gross and histopathological lesions and immunohistochemical findings were examined. 1. Feed conversion ratio in dual-infected pigs with PRRS virus and A. pleuropneumoniae were higher than that of single- infected pigs with PRRS virus or A. pleuropneumoniae. 2. Dual-infected pigs with PRRS virus followed by A. pleuropneumoniae showed more severe clinical signs and gross, histopathological and immunohistochemical pulmonary lesions. The results indicated that dual infections with PRRS virus and A. pleuropneumoniae caused more severe respiratory lesions and growth retardation in pigs than single infection with PRRS virus or A. pleuropneumoniae.

  • Human immunodeficiency virus is a retrovirus that causes acquired immunodeficiency syndrome. Acquired immunodeficiency syndrome is defined in terms of "either the occurrence of specific diseases in association with a HIV infection or a CD4 cell count below 200cells/ul" by centers for disease control and prevention(CDC). When performing the surgery of human immunodeficiency virus infected patients, several factors should be considered. First, standard precautions should be performed to prevent infection. It is safe to treat human immunodeficiency virus infected patients if we follow the standard precautions. Second, when making a surgical plan, surgeons have to take account of delayed bone healing and postsurgical infection. This case report presents a case of orthognathic surgery of human immunodeficiency virus infected patient.

  • Infected sweet potato (Ipomoea batatas) showing symptoms of sunken veins, stunting, mosaic, and mottling were collected from Gimje, Cochang, Iksan, and Haenam provinces in Korea. Electron microscopic (EM) observation of the infected tissue revealed rod and filamentous rod type virus particles of various lengths. Western blot analysis of the protein samples extracted from infected sweet potato and partially purified virus identified the isolates as Sweet potato feathery motile virus (SPFMV), Sweet potato latent virus (SwPLV), and Sweet potato chlorotic stint virus (SPCSV). Sweet potatoes were occasionally infected with more than one of these viruses. This is the first report of SwPLV and SPCSV in Korea.
