Catechol 2,3-dioxygenase (C23O), one of extradiol-type dioxygenases cleaving aromatic C-C bond at meta position of dihydroxylated aromatic substrates, catalyzes the conversion of catechol to 2-hydroxymuconic semialdehyde. As our ongoing study to characterize biochemical and genetic properties of the extradiol-type dioxygenases at molecular level, a C23O(More)
Herbal medicine, Herba Taraxaci (Tarazacum mongolicum Hand.-Mazz.), was administered to mice with Behcet's disease (BD)-like symptoms induced by herpes simplex virus (HSV). BD is a chronic recurrent inflammatory disease. Herba Taraxaci (6 mg) was administered alone or in combination with 2 microg of colchicine to BD-like mice. Colchicine is a drug that is(More)
Cytokine-induced neutrophil chemoattractant (CINC), a rat interleukin-8 (IL-8), was quantitated by using a sensitive ELISA. The CINC was induced up to 20 ng/ml from basal 1-2 ng/ml in lipopolysaccharide (LPS)-activated peritoneal macrophages. This CINC induction was significantly inhibited by steroidal anti-inflammatory drugs including dexamethasone, but(More)
INTRODUCTION It has become clear that obesity is associated with a variety of infectious diseases, including urinary tract infection (UTI) and renal scarring. OBJECTIVE The aim of this study was to evaluate the association between obesity and the degree of febrile UTI (fUTI) and renal scarring in children with vesicoureteral reflux (VUR), and to stratify(More)
CINC-1 is a member of chemokine family with chemotactic and activating properties to neutrophils. CINC-1 induction in IL-1beta-stimulated rat fibroblast NRK-49F cells was quantitated by a sensitive ELISA. CINC-1 production was increased up to 135 ng/ml from basal 2-6 ng/ml by stimulation with IL-1beta. Steroidal anti-inflammatory drugs including(More)
An inhibitor on CINC-1 (cytokine-induced neutrophil chemoattractant-1) induction in LPS-stimulated rat kidney epithelioid NRK-52E cells was purified from the roots of Sassurea lappa Clarke, a herbal medicine used in Korean traditional prescriptions for gastric intestinal diseases by a variety of column chromatographic procedures. The inhibitor was(More)
