Familial amyloidotic polyneuropathy (FAP) is a hereditary disease characterized by the systemic accumulation of amyloid fibrils. A mutant transthyretin (TTR) gene is mainly responsible for the disease. However, the variable age of onset and low penetrance might be due to environmental factors, one of which is the intestinal flora. Three types of intestinal(More)
We examined quantitatively the vaginal flora of conventionally reared mice, rats, hamsters, rabbits and dogs, species that are widely used as laboratory animals. Vaginal specimens were examined according to the method of analyzing intestinal flora (Mitsuoka's procedure). The total number of bacteria (aerobes and anaerobes) and the prevalence of specific(More)
Adult T-cell leukemia (ATL) is an aggressive neoplasm caused by human T-cell leukemia virus type I (HTLV-I). The nuclear transcription factor, NF-kappaB, is induced by HTLV-I and is central to the ensuing neoplasia. To examine the effect of a novel NF-kappaB inhibitor, dehydroxymethylepoxyquinomicin (DHMEQ), on ATL in vivo, we developed an improved severe(More)
We previously showed that an intraperitoneal infection with mouse hepatitis virus (MHV) persists in interferon-gamma (IFN-gamma)-deficient C57BL/6 (B6-GKO) mice and results in subacute fatal peritonitis, which bears a resemblance to feline infectious peritonitis. To examine the role of other host factors in MHV infection in mice, IFN-gamma-deficient mice(More)
It has been suspected that embryos stored in liquid nitrogen tanks may become contaminated with murine pathogens, if some pathogens had been introduced to the tanks accidentally. To examine this, we stored tubes containing embryos with tubes containing mouse hepatitis virus (MHV) or Pasteurella pneumotropica in liquid nitrogen tanks and examined whether(More)
Noroviruses cause most cases of acute viral gastroenteritis worldwide. The lack of a cell culture infection model for human norovirus necessitates the use of molecular methods and/or viral surrogate models amenable to cell culture to predict norovirus inactivation. Murine norovirus (MNV) may be used to construct a small animal model for studying the biology(More)
PURPOSE To compare the degree of surgical-field contamination in cataract surgeries between a new draping method using a lid speculum with a drape (LiDrape(®)) and a conventional draping method. METHODS Cataract surgery was performed on 21 eyes using LiDrape(®) (LiDrape(®) group) and on 22 eyes using a conventional draping method (conventional group).(More)
Klebsiella pneumoniae usually shows intrinsic resistance to ampicillin and other beta-lactams. bla(SHV) is thought to be a key beta-lactamase gene responsible for this intrinsic resistance to ampicillin. Nevertheless, surveys of clinical strains reveal that some isolates of K. pneumoniae that carry bla(SHV) remain susceptible to ampicillin. To explore(More)
Human T cell leukemia virus type I (HTLV-I), the etiological agent of adult T cell leukemia, integrates into the host genome as a provirus. Multiple defective copies of the integrated provirus are often present in the host genome. For this reason it is difficult to clone the intact provirus from HTLV-I-infected cells using conventional techniques. Here, we(More)
