BACKGROUND T cells are known to play a major role in the pathogenesis of atopic allergic asthma, but it is less clear whether they are involved in occupational asthma caused by low molecular weight chemicals such as plicatic acid. OBJECTIVE We sought to determine whether peripheral blood T cells

BACKGROUND Cry-consensus peptide, a recombinant T-cell epitope peptide for immunotherapy of Japanese cedar pollinosis, is a linear peptide that does not have disulfide bonds because no cysteine residue exists in the molecule. We examined whether a sandwich enzyme-linked immunosorbent assay (ELISA)

To investigate the sequence of cellular and protein changes after a late asthmatic reaction (LAR), bronchial lavage was carried out in 44 patients with red cedar asthma at different time intervals after bronchial challenge with plicatic acid. The results were compared to five patients with red cedar

BACKGROUND Multiple sensitizations in early age have been reported to be a risk for development of asthma. This study evaluates the emergence and evolution of IgE to aeroallergens among a cohort of children with physician-diagnosed atopic dermatitis and/or showing food allergy symptoms and to

BACKGROUND Dust mite, cockroach, and mold extracts have been shown to contain proteases capable of degrading the proteins in other extracts. Loss of potency of allergens has been reported in mixtures containing cockroach and fungal extracts. Fire ant venoms consist of 90% to 95% n-alkyl and

Two carpenters developed asthma and rhinitis related to occupational exposure to a cedar urea formaldehyde (CUF) particle board. One patient developed nasal and chest symptoms and an equivocal early asthmatic response after CUF sawdust exposure, but not after spruce or western red cedar sawdust

A worker developed symptoms of work-related asthma a few weeks after starting to work in a sawmill where eastern white cedar (Thuja occidentalis) was transformed into shingles. The diagnosis of occupational asthma was confirmed by monitoring of peak expiratory flow rates and bronchial responsiveness

In order to investigate the relationship between the pattern of response (immediate, late and dual) to specific bronchial challenge test with plicatic acid or red cedar extract and the clinical features of asthma, 332 patients with asthma induced by western red cedar dust were examined at the time

In a cross-sectional survey of 652 workers in a western red-cedar sawmill, we obtained data on symptoms, pulmonary function, immediate skin reactivity to common allergens, nonspecific bronchial responsiveness, total IgE level, and sensitization to plicatic acid conjugated with human serum albumin as

BACKGROUND Occupational asthma caused by western red cedar (Thuja plicata) is a common problem in sawmill industries. The objective of this study was to examine the cellular and immunologic mechanisms of western red cedar asthma (WRCA) more closely. METHODS Bronchial biopsy specimens,

Four workers from a cedar sawmill who developed red cedar asthma are described. They had serial measurements of lung function and nonspecific bronchial hyperresponsiveness (NSBH) several years before and after the development of chest symptoms. Measurements of dust concentration and specific IgE

Seventeen patients with occupational asthma due to western red cedar had bronchial lavage during follow-up examination after removal from exposure for at least 1 year. Seven patients were asymptomatic while ten continued to have symptoms of asthma requiring treatment. Symptomatic patients had

Occupational asthma due to Western Red Cedar (WRCA) is attributed to sensitization to plicatic acid (PA), but does not appear to be dependent on PA-specific IgE antibodies. Exposure to PA induces histamine release in vivo and in vitro, so if IgE is not important, other mechanisms of histamine

BACKGROUND Japanese cedar (Cryptomeria japonica; CJ) pollinosis has been reported to occur naturally in Japanese monkeys (Macaca fuscata) as well as in humans. Most human patients and monkeys with pollinosis have specific IgE for Cry j 2, a major allergen of CJ pollen. OBJECTIVE The main purpose of

We examined urea used as a dilution marker of broncho-alveolar lavage fluid to determine whether it was also useful as a dilution marker of nasal lavage fluid. We measured the concentration of urea in nasal secretions and peripheral blood for 91 cases. As a comparison, we also measured the total
