Liver fibrosis represents a process of healing and scarring in response to chronic liver injury. Following injury, an acute inflammation response takes place resulting in moderate cell necrosis and extracellular matrix damage. Melittin, the major bioactive component in the venom of honey bee Apis mellifera, is a 26-residue amphipathic peptide with(More)
Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare T-cell lymphoma characterized by involvement of the subcutaneous tissue of neoplastic T lymphocytes. SPTCL with hemophagocytic syndrome (HPS) is associated with an aggressive clinical course and treatment of SPTCL with HPS is not well established. Cyclophosphamide, doxorubicin, vincristine,(More)
This study is designed to confirm the anti-fibrotic effect of thalidomide on bleomycin-induced lung fibrosis in a mouse model and to identify whether this anti-fibrotic effect is associated with inhibition of the transforming growth factor-β (TGF-β)-induced extracellular signal-regulated kinase1/2 (ERK1/2). C57BL/6 female mice were administered blomycin(More)
The aim of this study is to evaluate the antifibrotic effect of ring-type Sp1 decoy oligonucleotides (ODNs) through blocking the transcription of transforming growth factor (TGF)-beta1 and its downstream target genes. In this experiment, the expression of TGF-beta1, metalloproteinase (MMP)-13, and fibronectin was decreased in the group with the treatment of(More)
Amyopathic dermatomyositis (ADM) is recognized as a variant phenotype of dermatomyositis and characterized by typical skin manifestations without evidence of muscular inflammation. While interstitial lung disease (ILD) is occasionally found as one of the lung manifestations in ADM patients, the development of a pneumomediastinum and/or subcutaneous(More)
Alcohol consumption increases apoptosis of hepatocytes. Death of hepatocytes is a characteristic feature of chronic liver disease for various causes. Bee venom (Apis mellifera) has been traditionally used for the treatment of various chronic diseases, such as chronic inflammatory arthritis and chronic liver disease. However, the precise mechanism for bee(More)
Received October 2009 Accepted November 2009 INTRODUCTION A gastrointestinal stromal tumor (GIST) is primarily located in the gastrointestinal tract. It is classified as a mesenchymal tumor that shows a CD117 (c-KIT)-positive mesenchymal spindle or epithelioid neoplasm. Tumors outside the gastrointestinal tract that were histologically similar to GISTs and(More)
INTRODUCTION Diffuse large B cell lymphoma (DLBCL) of primary nodal (PN) or primary extranodal (PEN) origin may differ immunophenotypically, in that PEN lymphoma cells may originate from activated rather than germinal center B (GCB) cells. We evaluated the relationship between DLBCL clinicopathological features, including expression of B-cell(More)
