This study was conducted to determine the immunogenicity and safety of an inactivated split-virus influenza A/H1N1 vaccine in healthy Korean children from 6 months to <18 years of age. The immunization schedule consisted of two vaccinations, 21 days apart. The unadjuvanted vaccine contained 7.5microg (subjects 6 months to <3 years of age) or 15microg(More)
The platelet-rich plasma (PRP) from 35 healthy Korean volunteers were challenged by four catecholamines and clonidine, which were known as alpha-adrenergic agonists. Wide individual variations were observed with the respect to the pattern and the degree of aggregation in response to each agent. They fall into five distinct groups; Group A (2.9%) was(More)
We report results of a randomized, double-blinded, active-controlled, phase III study conducted to evaluate the immunogenicity and safety of a new trivalent inactivated split-virus influenza vaccine (GC501) manufactured by the Green Cross Corporation in Korea. A total of 283 healthy children aged 6 months to < 18 yr were randomized to receive either GC501(More)
We previously reported the development of a neutralization assay system for evaluating Japanese Encephalitis Virus (JEV) neutralizing antibody (NAb) using pseudotyped-JEV (JEV-PV). JEV-PV-based neutralization assay offers several advantages compared with the current standard plaque-reduction neutralization test (PRNT), including simplicity, safety, and(More)
Efficient gene delivery of a baculovirus-derived vector (BV-p53-lacZ) to a human osteogenic sarcoma cell line, Saos-2, was serendipitously found while evaluating the vector for gene delivery to human p53-null tumour cells in a previous study. Therefore, we investigated other human, rat and mouse osteogenic sarcoma and other types of tumour cell lines for(More)
Antioxidants have been shown to be effective in murine models of sepsis. Protocatechuic acid has antioxidant activity. In the present study, the protective effects of protocatechuic acid and its derivatives were investigated in a mouse model of septic shock induced by lipopolysaccharide (LPS)/D-galactosamine (GalN). Pretreatment of animals with(More)
Infantile spasm is an age-related refractory epilepsy. Topiramate is a new anticonvulsant with multiple mechanisms of action, and it may be effective for treating pediatric epilepsies. To evaluate the efficacy and tolerability of first-line topiramate treatment for infantile spasm, 20 patients received topiramate monotherapy during this study. They were(More)
OBJECTIVES Several different methods are currently used to detect antibodies to Japanese encephalitis virus (JEV) in serum samples or cerebrospinal fluid. These methods include the plaque reduction neutralization test (PRNT), the hemagglutination inhibition (HI) test, indirect immunofluorescence assay (IFA), and enzyme-linked immunosorbent assay (ELISA).(More)
Five aporphine alkaloids, N-acetylanonaine ( 1), N-acetylxylopine ( 2), N-formylanonaine ( 3), liriodenine ( 4), and lanuginosine ( 5) as the antiplatelet constituents, were isolated from the methanol extract of leaves of Magnolia obovata. This is the first reported occurrence of 2 and 3 from genus Magnolia and 5 was isolated from this plant for the first(More)
The regeneration of hyaline articular cartilage by cell-mediated gene therapy using transforming growth factor beta(1) (TGF-beta(1))-producing fibroblasts (NIH 3T3-TGF-beta(1)) has been reported previously. In this study, we investigated whether TGF-beta(1)-producing fibroblasts irradiated with a lethal dose of radiation are still capable of inducing the(More)
