Purpose: Recently, there has been several studies to clarify the pathogenesis of Kawasaki disease (KD) and the relations of VEGF and endostatin that act on vascular endothelial cells to the coronary artery complications. In this report, we measured serum levels of VEGF and endostatin in acute and subacute phases of KD to assess the change of these levels and the... |
The major pathogenesis of acute respiratory distress syndrome (ARDS) is an inflammatory process that results from a diversity of injuries to the body. Due to the various cytokines and vasoactive peptides released from the endothelium, the vascular permeability is increased; the migration of inflammatory cells and the leakage of plasma proteins then occur and edema develops in the alveolus. There... |
Purpose : Kawasaki disease is the most common cause of systemic vasculitis in children less than 5 years of age. Recent immunohistochemistry findings suggest that many vascular growth factors play a role in the formation of the coronary artery lesions. Active remodeling of the coronary artery lesions in Kawasaki disease continues in the form of intimal proliferation and neoangiogenesis for... |
Purpose : Kawasaki disease(KD) manifests a systemic vasculitis of unknown etiology in young children. Vascular endothelial growth factor(VEGF), vascular cell adhesion molecule-1(VCAM-1) and interleukin-1 beta(IL-1β) may play important roles in the pathogenesis of KD. Intravenous immunoglobulin(IVIG) and methylprednisolone(MP) are therapeutically effective for KD, however, the precise mechanisms of the two drugs are still unknown. We investigated the therapeutic efficacy of... |
Purpose : Viral respiratory infection, especially respiratory syncytial(RS) virus, can predispose sufferers to the development of asthma by mechanisms that are presently undetermined. The role of inflammatory mediators in pathogenesis of asthma and RS virus disease is not well-understood. We investigated the performance of serum eosinophil cationic protein(ECP), regulated on activation normal T-cell expressed and secreted(RANTES) and eotaxin levels on... |
Hemophagocytic lymphohistiocytosis is a reactive disorder characterized by a generalized non-malignant histiocytic proliferation with prominent hemophagocytosis by stimulated histiocytes in the bone marrow and reticuloendothelial systems resulting in pancytopenia and liver dysfunction.
