Examination of induced sputum and measurement of exhaled NO have been advocated as noninvasive methods of assessing the degree of airway inflammation. In this study, we performed follow-up evaluation on 71 subjects with asthma caused by exposure to Western red cedar; 50 subjects had left exposure,

Bronchoalveolar lavage cells and bronchial biopsies were obtained from nine patients with red cedar asthma, six atopic asthmatics and six non-atopic, non-asthmatic control subjects. There were similar proportions of neutrophils, mast cells, lymphocytes, and macrophages in BAL samples from all three

Ethnobotanical surveys indicated that in the traditional medicines worldwide, several Juniperus species are utilized as antihelmintic, diuretic, stimulant, antiseptic, carminative, stomachic, antirheumatic, antifungal, and for wound healing. In the present study, essential oils obtained from

BACKGROUND Prior research has shown that removing occupational asthmatics from exposure does not routinely lead to significant improvements in respiratory impairment. These studies were of limited duration and factors determining recovery remain obscure. Our objective was to evaluate residual

Plicatic acid, a low-molecular-weight compound responsible for western red cedar (Thuja plicata) asthma was tested for its ability to activate complement and to generate chemotactic activity from pooled normal human serum (NHS). Dose-dependent complement consumption was found as determined by

Examination of sputum for eosinophils and measurement of exhaled nitric oxide have been proposed as noninvasive methods of assessing airway inflammation in asthma. The use of these tests in the evaluation of patients with occupational asthma has not been reported. This study investigated the changes

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

BACKGROUND First Nations people have a long history of working with medicinal plants used to treat skin diseases. The purpose was to assess the dermatologic therapeutic potential of western red cedar, white spruce, birch, balsam poplar, and black spruce. METHODS Based on expert recommendations, 5

BACKGROUND The pathogenesis and the pathologic alterations of occupational asthma are similar to those of nonoccupational asthma. Occupational asthma may therefore represent a useful model of "human asthma" to investigate mechanisms and pathophysiology of asthma in general. In an occupational

Although late bronchospastic reactions after exposure to antigenic and sensitizing agents usually significantly alter bronchial responsiveness to histamine or methacholine, presumably by causing bronchial inflammation, isolated immediate bronchospastic reactions do not induce such changes. We

Dear Editor, Erythema multiforme is considered an acute skin condition, characterized by a self-limiting and sometimes recurrent course. It is regarded as a type IV hypersensitivity reaction associated with certain infections, medications, and other various triggers. Allergic contact dermatitis is

Several studies on the prognosis of isocyanate-induced asthma show that a significant proportion of patients continue to experience asthmatic symptoms and nonspecific bronchial hyperresponsiveness after cessation of work, and that further exposure to isocyanates in sensitized subjects leads almost
