A total of 175 human immunodeficiency virus (HIV)-positive intravenous drug users (IDU) with CD4 cell counts of <200 cells/microl were matched with 175 HIV-positive IDU with CD4 cell counts of >500 cells/microl. Enzyme immunoassay (EIA) reactivity and human T-cell lymphotropic virus type 2 (HTLV-2) Western blot (WB) positivity were more frequently observed in subjects with CD4 cell counts of >5...

A neutralization enzyme immunoassay (N-EIA) was used to determine the neutralizing serum antibody titers to influenza A/Taiwan/1/86 (H1N1) and Beijing/353/89 (H3N2) viruses after vaccination of 51 human immunodeficiency virus (HIV) type 1-infected individuals and 10 healthy noninfected controls against influenza virus infection. Overall, the N-EIA titers correlated well with the hemagglutinatio...

Background EIA (Exercise-induced Asthma) can be considered a marker of severity and disease control in asthma. There are several diagnostic tools to evaluate airway hyperresponsiveness in EIA, but it has not been establish the best one. Our objective is to explore bronchial hyperresponsiveness with different lung function measurement techniques among a pediatric population with clinical history...

This paper categorizes and reviews different approaches to environmental impact assessment (EIA) system evaluation. It then describes the application of Wood’s (1995) ‘ideal’ EIA system evaluation criteria to the Republic of Maldives. Few of the criteria are actually met. Is the Maldivian EIA system therefore fundamentally flawed or deficient? Field observations suggest that this is not so and,...

Sera collected from 90 multiple sclerosis patients and 148 age-matched normal subjects were examined for the presence of antibodies against human coronaviruses (HCV) 229E and OC43 by enzyme immunoassay (EIA). The results demonstrated no significant difference between the MS patients and the normal subjects in their antibody titer to HCV 229E and HCV OC43. Further analysis of these 238 sera indi...

To compare the effectiveness of cromolyn sodium (CS) (10 mg) and nedocromil sodium (NS) (4 mg) administered by a metered dose inhaler (MDI) with a spacer device in preventing exercise-induced asthma (EIA), eight asthmatic children with EIA were studied in a randomized double-blind, cross-over, placebo-controlled study, CS and NS provided significant, comparable protection from EIA and both were...

serum cortisol level was measured by an enzyme immunoassay (eia) using the enzyme penicillinase as a label without prior extraction and purification. polyclonal antibodies were raised against cortisol-3-ortho-carboxymethyl-oxime (cortisol-3-0-cmo) conjugated to bovine serum albumin (bsa). this antibody showed a very low cross-reactivity with structurally related steroids (3.7% for corticosteron...

The BioElisa Syphilis, a new competitive enzyme immunoassay (EIA) for Treponema pallidum whole antigen that uses specific human immunoglobulin G (IgG) antibodies as the competitor, was evaluated for potential use in screening for syphilis at various stages. The results obtained by this competitive EIA were compared with those obtained by the fluorescent treponemal antibody absorption (FTA-abs) ...

BACKGROUND Asthma is the most common chronic diseases in school-aged children in Japan. It is important to consider health-related quality of life (QoL) among children with chronic diseases when treatment decisions are made. METHODS A school-based survey was conducted in randomly selected public schools in Tokyo by using a KINDL questionnaire for evaluating QoL and the international study of ...
