The xylanase B gene encoding a thermostable family 10 xylanase of Clostridium stercorarium was expressed in plants under the control of a constitutive promoter. Two forms of the xylanase B gene, the xynB gene encoding the full length of the xylanase B gene including the bacterial signal sequence and the xynBM gene without the signal sequence region, were(More)
BACKGROUND Granulocyte and monocyte adsorptive apheresis (GMA) with an Adacolumn has been reported to be effective as induction therapy in ulcerative colitis (UC). However, the effects of GMA on serial changes in cytokine levels have not been well characterized. We therefore, investigated cytokine levels in UC patients before and after treatment with GMA. A(More)
Two distinct domains of the xynA gene from Clostridium thermocellum encoding a xylanase catalytic domain (XynAl) and a xylanase catalytic domain with a cellulose binding domain (XynA2) under the control of the cauliflower mosaic virus 35S promoter were electroporated into cultured tobacco BY-2 cells. Transgenic BY -2 calli expressing xylan-hydrolyzing(More)
Colonic mucosa-associated lymphoid tissue (MALT) lymphomas are rare and a definitive treatment has not been established. Solitary or multiple, elevated or polypoid lesions are the usual appearances of MALT lymphoma in the colon and sometimes the surface may reveal abnormal vascularity. In this paper we report our experience with four cases of colonic MALT(More)
Follicular lymphomas occur rarely in the gastrointestinal tract, representing only 1-3% of all gastrointestinal tract B-cell non-Hodgkin lymphomas. We describe endoscopic analysis of 3 cases of follicular lymphoma in the small intestine using double-balloon endoscopy. Double-balloon endoscopy revealed multiple nodular lesions and elevated white patches,(More)
BACKGROUND/AIMS Infliximab (IFX) has been reported to be useful as induction therapy and/or maintenance therapy for Crohn's disease (CD). However, the effects of IFX on serial changes in cytokine levels have not been well characterized. We examined cytokine levels in CD patients before and after administration of IFX. METHODOLOGY A total of 37 patients(More)
Tumor necrosis factor α plays an important role in the pathogenesis of Crohn's disease (CD). The effects of infliximab on gastrointestinal bleeding in CD have not yet been fully evaluated. Herein we describe three CD cases who presented with gastrointestinal bleeding and received infliximab treatment. In case 1, double-balloon endoscopy showed a large ulcer(More)
Infection with Helicobacter pylori (HP) is common in many parts of the world. While most patients are asymptomatic, it causes peptic ulcer disease and malignancy in some of them. Other rare conditions have occasionally been reported in association with this infection. We report a case of hypertrophic gastropathy caused by HP in a 52-year-old asymptomatic(More)
BACKGROUND/AIMS We examined serum cytokine levels in Crohn's disease (CD) patients before and after Adalimumab (ADA) treatment. METHODOLOGY A total of 24 patients with CD were enrolled (4 colonic type, 6 ileal type, 14 ileo-colonic type). Patients were divided into two groups according to disease duration. Patients were given ADA (160 mg at week 0 and 80(More)
