The effects of beta-adrenoceptor agonists (beta-agonists) on the production of tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta) and interleukin-8 (IL-8) by lipopolysaccharide (LPS)-stimulated human peripheral blood mononuclear cells (PBMCs) were investigated. The beta-agonists, procaterol, clenbuterol, fenoterol and terbutaline,(More)
The lymphocyte stimulation test (LST) is useful for diagnosing drug-induced allergy and identifying the causative drug. In this study, we examined the usefulness of 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) as a marker for LST in diagnosing drug allergy. In a basic study using normal peripheral blood mononuclear cells, the normal(More)
1. The effects of cAMP-phosphodiesterase (PDE) isozyme inhibitors on the production of tumor necrosis factor alpha (TNF-alpha), and interleukins 1 beta 8 (IL-1 beta and IL-8) by lipopolysaccharide (LPS)-stimulated human peripheral blood mononuclear cells (PBMC) were evaluated. In addition, we investigated the effects of dibutyryl cAMP (dbcAMP) and(More)
Roxithromycin (RXM), a new macrolide antibiotic, has a 14-member macrocycline ring structure which is similar to that of erythromycin. We investigated the effects of RXM on the proliferation of peripheral blood mononuclear cells (PBMCs) and the production of interleukin 1 beta (IL-1 beta) and tumor necrosis factor alpha (TNF-alpha) by PBMCs stimulated with(More)
Levofloxacin (LVFX), the bacteriologically active isomer of ofloxacin, is a fluorinated quinolone. LVFX suppressed the proliferative activity of peripheral blood mononuclear cells (PBMC) stimulated with phytohemagglutinin (PHA). LVFX increased interleukin-2 (IL-2) production by PBMC stimulated with PHA in a dose-dependent manner, with more than 10(More)
Theophylline is a mild bronchodilator and has significant extrapulmonary effects, but it may also have some anti-inflammatory properties. We investigated the immunological effects of theophylline on peripheral blood mononuclear cells (PBMC), by examining the production of interleukin-1 beta (IL-1 beta), tumor necrosis factor-alpha (TNF-alpha), and(More)
The lymphocyte stimulation test (LST) is one of the most useful laboratory tests for the identification of allergy to a specific drug. The present study was conducted to examine utility of the LST using the [3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide] (MTT) assay as a method for diagnosing drug allergy. The basic experimental conditions(More)
