ETHNOPHARMACOLOGICAL RELEVANCE Ginger, Zingiber officinale Roscoe, is a common spice and also a widely used medicinal plant in ancient China. Ginger is an ingredient of Ge-Gen-Tang (Kakkon-to; GGT). GGT has been proved to have antiviral activity against human respiratory syncytial virus (HRSV). However, it is unknown whether ginger is effective against(More)
Respiratory syncytial virus (RSV) is a major cause of pneumonia and bronchiolitis in infants and elderly people. Currently there is no effective vaccine against RSV, but passive prophylaxis with neutralizing antibodies reduces hospitalizations. To investigate the mechanism of antibody-mediated RSV neutralization, we undertook structure-function studies of(More)
BACKGROUND Chronic kidney disease (CKD) and hepatitis C virus (HCV) infection are closely linked and both increase patient mortality. The association of HCV and risk of developing end-stage renal disease (ESRD) has not been analyzed with competing risk model. METHOD We enrolled a prospective cohort of 4,185 patients (mean age, 62 years; 41% female)(More)
Human infection by enterovirus type 71 (EV71) can cause life-threatening meningo-encephalitis. Currently, there is no effective anti-EV71 therapy available. Since EV71 infection commonly involves skin lesions, we tested our hypothesis that water extract of Glycyrrhiza uralensis (G. uralensis) could inhibit the cytopathic effects of EV71 in a human foreskin(More)
Dengue is a timing disease, and frequently dengue patients do not seek help until 2-3 days after prodrome. Thus, the innate immune parameters in dengue patients remain largely unexplored. A comprehensive FACS profiling of key innate immune cells in the peripheral blood of dengue patients was performed. Twenty-seven dengue patients varying in days of fever(More)
BACKGROUND Persistent activation of hepatic stellate cells (HSC-T6) has been known to cause liver fibrosis. In this study, our objective was to investigate the effects of chebulagic acid and chebulinic acid, two hydrolysable tannins of tropical almond (Terminalia chebula) fruits, on collagen synthesis and signal transduction in transforming growth(More)
The present study evaluated the antiviral activity of Bidens pilosa L. var. minor (Blume) Sherff and Houttuynia cordata Thunb., using cytotoxicity test with XTT-based colorimetric assay. BCC-1/KMC cells were infected with herpes simplex virus (HSV) and then were cultured with hot water extract of B. pilosa (HWBP) or H. cordata (HWHC). Results showed that(More)
BACKGROUND AND PURPOSE Dengue fever (DF) is a major public health issue. However, it is unclear whether different dengue virus serotypes (DENV) are associated with different clinical manifestations and outcomes. This study investigated the association between viral serotype and clinical manifestations of DF. METHODS Adult patients with DENV-2 and DENV-3(More)
Chronic hepatitis B virus (HBV) infection is endemic in Asia and its consequences are among the major public health problems in the world. Unfortunately, the therapeutic efficacies of present strategies are still unsatisfactory with a major concern about viral mutation. In search of effective antiviral agent, we examined the efficacy of extracts of(More)
ETHNOPHARMACOLOGICAL RELEVANCE Sheng-Ma-Ge-Gen-Tang (SMGGT), a popular prescription of Chinese traditional medicine, has been used to manage measles infection of children for thousands of years. There are evidences to presume a wider spectrum of antiviral activity of SMGGT. However, SMGGT has not been proven to have activity against EV71 infection. AIM OF(More)
