Enterohemorrhagic Escherichia coli (EHEC) O157:H7 has been considered as an agent responsible for outbreak of hemorrhagic colitis and the hemolytic uremic syndrome. We examined the effect of the probiotic agent Clostridium butyricum MIYAIRI strain 588 on EHEC O157:H7 infections in vitro and in vivo using gnotobiotic mice. The growth of EHEC O157:H7 and the(More)
BACKGROUND Photodynamic therapy (PDT) is a new palliative option in patients with non-resectable bile duct carcinoma (BDC). Here, we assessed the efficacy of adjuvant photodynamic therapy in eight patients with BDC who underwent surgical resection. METHODS Five patients had extrahepatic BDC, two had intrahepatic cholangiocarcinoma, and one had ampullary(More)
OBJECTIVE To investigate the biological significance of single nucleotide polymorphism at codon 72 of the p53 gene in the development of gynecological cancer. METHODS p53 codon 72 polymorphism was examined in a total of 354 blood samples from 95 normal, 83 cervical, 108 endometrial and 68 ovarian cancer cases using polymerase chain reaction and(More)
A cell wall hydrolase homologue, Bacillus subtilis YddH (renamed CwlT), was determined to be a novel cell wall lytic enzyme. The cwlT gene is located in the region of an integrative and conjugative element (ICEBs1), and a cwlT-lacZ fusion experiment revealed the significant expression when mitomycin C was added to the culture. Judging from the Pfam data(More)
Survivin is a novel inhibitor of apoptosis and is expressed during fetal development and in cancer tissues, but its expression has not been reported in normal adult tissues or benign diseases. We investigated survivin gene and protein expression in a tumor-like benign disease, endometriosis, and correlated them with apoptosis and invasive phenotype of(More)
The effects of long-term infection with Helicobacter pylori on the gastric mucosa of Mongolian gerbils were examined. Colonization by H. pylori was evaluated by both microaerobic cultivation and real-time reverse transcriptase PCR (RT-PCR). Persistent infection with H. pylori in gastric mucosa was detected by real-time RT-PCR during 6 months after(More)
Sialyl Lewis(a) (CA19-9) and sialyl Lewis(x) antigens (SLX) may play a role in tumor metastasis by serving as functional ligands in the cell adhesion system. The authors examined preoperative serum levels of CA19-9 and SLX in 218 patients who underwent resection for gastric cancer to determine their prognostic value. The patients were divided into two(More)
The metastasis suppressor gene nm23 located on chromosome 17 might be one of the targets in deletions of chromosome 17. In this study, we analyzed the expression of nm23 and chromosome 17 aberrations in gastric cancer and assessed their clinicopathological and prognostic significance. In 103 gastric cancer patients, we examined nm23 expression by(More)
A minimally invasive surgical approach should be employed to resect symptomatic colonic lipomas whenever possible. We report two cases of large colonic lipomas that were successfully removed using a minimally invasive minilaparotomy approach. Patient 1 was a 53-year-old man with a 3.8-cm symptomatic submucosal lipoma in the ascending colon and patient 2 was(More)
We evaluated the efficiency of measuring hyaluronic acid (HA) levels preoperatively in patients with injured liver disease as a predictor of complications after hepatectomy. We examined patients who underwent hepatectomy for liver tumors secondary to chronic viral liver diseases or obstructive jaundice. The preoperative HA level correlated significantly(More)
