PURPOSE Patterns of prescriptions are markedly influenced by regional disease entities, medical education, culture, economic status, and available pharmaceutical companies. Features of adverse drug reactions (ADRs) may vary in different countries. In this study, we analyzed the causative drugs and clinical manifestations of spontaneously reported ADRs in(More)
TNF-related apoptosis-inducing ligand (TRAIL/Apo- 2L), a newly identified member of the TNF family promotes apoptosis by binding to the transmembrane receptors (TRAIL-R1/DR4 and TRAIL-R2/DR5). TRAIL known to activate NF-kappaB in number of tumor cells including A549 (wt p53) and NCI-H1299 (null p53) lung cancer cells exerts relatively selective cytotoxic(More)
Autoimmune inflammation in the central nervous system (CNS) is maintained by secretion of a large number of cytokines. To elucidate its molecular mechanisms, we examined the expression and localization of STAT1, STAT3, STAT4 and STAT6 molecules, which are the downstream molecules of the cytokine signal transduction pathway, in the CNS during acute(More)
The involvement of inducible nitric oxide synthase (iNOS) and tumor necrosis factor alpha (TNF-alpha), which have diverse roles in the progression of autoimmune disease models, was studied in pertussis toxin (PT)-induced hyperacute experimental autoimmune encephalomyelitis (EAE) in Lewis rats. The expression of TNF-alpha mRNA (increased 5-fold, P<0.01) and(More)
BACKGROUND Although asthma is a common cause of morbidity in adults, relatively few objectively measured population studies of asthma prevalence in adult populations have been conducted. OBJECTIVE To evaluate the prevalence of asthma, based on both a questionnaire and methacholine bronchial provocation test, and to determine the risk factors of asthma(More)
To examine whether children with a genetic predisposition to asthma are more likely to be afflicted with bronchiolitis, we studied 122 parents of infants who were hospitalized with the diagnosis of acute bronchiolitis (index group) and 120 parents of children who had never suffered from this disease (control group). The parents underwent bronchial challenge(More)
Increased expression of a number of cytokines including GM-CSF is associated with chronic inflammatory conditions such as bronchial asthma. Glucocorticoid therapy results in suppression of cytokine levels by a mechanism(s) not yet fully understood. We have examined regulation of GM-CSF expression by the synthetic glucocorticoid dexamethasone in human T(More)
Adverse reactions induced by antituberculosis drugs (ATD) often result in serious morbidities, impeding scheduled treatment and cure. In the development of ATD-induced adverse reactions, glutathione S-transferase has been suggested to play a protective role as an intracellular scavenger by conjugating toxic reactive metabolites of ATD. This study examined(More)
Recent investigations suggest genetic susceptibility of allopurinol-induced severe cutaneous adverse reactions (SCARs). However, the strength of association was variable according to phenotypes and ethnic backgrounds. To explore genetic markers for allopurinol-induced SCARs in Koreans, we genotyped human leukocyte antigen (HLA) class I alleles of 25 cases(More)
BACKGROUND In most epidemiological survey studies, only subjective symptoms and past medical history of asthma have been used as diagnostic criteria. Even though a questionnaire survey can be performed in a large population study at low cost, limitations such as lack of objectivity and poor predictability in non-specific bronchial hyperresponsiveness cannot(More)
