We investigated the role of tumor necrosis factor (TNF)-alpha in the onset of neuronal and glial apoptosis after traumatic spinal cord crush injury in rats. A few TUNEL-positive cells were first observed within and surrounding the lesion area 4 h after injury, with the largest number observed 24-48 h after injury. Double-labeling of cells using cell(More)
OBJECTIVE To identify predictive factors for nephritis, relapse, and significant proteinuria in childhood Henoch-Schönlein purpura (HSP). METHODS Two hundred and six consecutive patients with HSP (93 female, 113 male), followed up at a single centre between 1996 and 2001, were analysed retrospectively. They were regularly monitored for clinical and(More)
Ginsenosides are main pharmacoactive molecules of ginseng. The antinociceptive activity of ginsenosides after intrathecal (i.t.) injection was examined in formalin test. We also investigated the effects of ginsenosides on substance P (SP) induced-pain behaviors by i.t. treatment using mice. Pretreatment of ginsenosides by i.t. induced the inhibition of(More)
AIMS To clarify the role of mesangial fibrinogen deposition in crescentic Henoch-Schönlein nephritis (HSN). METHODS A retrospective analysis of 21 children with HSN treated with immunosuppressants. Serial renal biopsies were performed before and after treatment. They were divided into two groups according to the immunofluorescent course of fibrinogen(More)
The reduced incidence of cancer observed in schizophrenia patients may be related to differences in genetic background. It has been suggested that genetic predisposition towards schizophrenia is associated with reduced vulnerability to lung cancer, and p53 gene is one of the candidate genes. We tested the genetic association between schizophrenia and lung(More)
AIM The aim of the study was to evaluate the impact of vitiligo on the quality of life and psychological adaptation in a Korean adolescent population. METHODS Fifty-seven adolescents aged 12 to 18 years with vitiligo were evaluated using self-report scales, namely the Skindex-29, Piers-Harris self-concept, Center for Epidemiologic Studies Depression Scale(More)
Ginseng root, a traditional oriental medicine, contains more than a dozen biologically active saponins called ginsenosides, including one present in only trace amounts called ginsenoside-Rf (Rf). Previously, we showed that Rf inhibits Ca2+ channels in mammalian sensory neurons through a mechanism requiring G-proteins, whereas a variety of other ginsenosides(More)
Interleukin (IL)-4 has been demonstrated to have anti-inflammatory and anti-tumour activity. Because aberrant angiogenesis is a significant pathogenic component of tumour growth and chronic inflammation, we investigated the effect of IL-4 on the production of vascular endothelial growth factor (VEGF) by synovial fibroblasts derived from patients with(More)
Ginsenoside Rc, Rd, and Re induced antinociception in writhing and formalin tests among five representative ginsenosides: Rb1, Rc, Rd, Re, and Rg1. However, these ginsenosides had no effect in the tail-flick test. The antinociceptive effects induced by three ginsenosides were dose dependent. ED50 was 20.5 (7.3-57.4 mg/kg) for Rc, 17 (11.0-27.6 mg/kg) for(More)
The RET (rearranged during transfection) proto-oncogene encodes a receptor tyrosine kinase for members of the glial cell line-derived neurotrophic factor family of extracellular signaling molecules. The activating germline point mutations in the RET, which are known to induce oncogenic activation of RET tyrosine kinase, are associated with the development(More)
