13. Resposta imune humoral e celular a Blomia tropicalis e sua fração ligante de Concanavalina A em pacientes atópicos
Blomia tropicalis (Bt), Dermatophagoides pteronyssinus (Dp) and D. farinae (Df) are the prevalent house dust mites (HDMs). Concanavalin A-binding components derived from B. tropicalis (Bt-ConA extract) have shown to be highly immunogenic in allergic diseases. This study aimed to evaluate the humoral and cellular immune responses to B. tropicalis in sensitize

15. Variação sazonal nas concentrações de aeroalérgenos em diferentes níveis de poluição ambiental / Seasonal variation in aeroallergens concentrations in different degrees of air pollution
OBJETIVOS: Estudar o ambiente interno em escolas públicas situadas em duas cidades (Atibaia e São Paulo), com diferentes níveis de poluição atmosférica, mediante a identificação e quantificação dos principais alérgenos presentes na poeira e no ar das salas de aula dessas escolas, assim como a avaliação da existência de padrão sazonal para cada

16. Responses of IgE, IgG1, and IgG4 to concanavalin A-binding Blomia tropicalis antigens in allergic patients
Blomia tropicalis (Bt) and Dermatophagoides pteronyssinus (Dp) are the prevalent house dust mites in tropical countries and are associated with allergic diseases. Glycosylated antigens are highly immunogenic and involved in different pathologies. We evaluated the presence of IgE, IgG1, and IgG4 to concanavalin A-binding antigens (Bt-Con-A) isolated from Bt-t

17. Avaliação da sensibilidade imediata de pacientes atopicos por meio de teste cutaneo de puntura (prick test) a extrato de traça-de-livro (Lepisma saccharina) padronizado em unidades biologicas / Evaluation of immediate sensitive to a biological Unit-Standardized extract of silverfish (Lepisma saccharina) in atopic patients by skin prick test
In Brazil, allergic patients with allergic rhinitis and/or asthma present sensibility for several aeroallergens mainly from house dust mites. Other potential sources of allergens like silverfish remain to be investigated as really allergenic and firmly related to respiratory allergic diseases. The aim of this study was investigate by skin prick test the imme

18. Níveis de alérgenos inaláveis em veículos utilitários de transporte escolar em Uberlândia, MG
The allergen exposure is considered crucial for the development of allergies. The aim of this study was to measure mite (Der p 1 and Der f 1), dog (Can f 1) and cat (Fel d 1) allergens, in school transport vehicles. It was analized 163 seat dust samples from 60 vehicles, using ELISA tests. The Can f 1 allergen was the most frequent (geometric mean = 1.03 g/g

20. Investigação sobre associação entre ácaros da poeira, atopia, manifestações alérgicas e infecções intestinais helmínticas. / Investigation beetween dust mites, atopy allergy and intestinal helminthic infections.
The role of dust mites in the determination of the clinical form of allergy has not been well established. Many records in the literature show negative association between helminth infections and allergy, however, these data are still controversial. In this study we investigated the role of B. tropicalis and D. pteronyssinus as agents of atopy and allergy an

21. Avaliação da fauna acarina em amostras de poeira de colchões na cidade de Campinas e comparação com a sensibilidade cutanea imediata de pacientes atopicos
House dust mites (HOM) have been considered the major source of allergens in dwellings, being mattresses and pillows the most important reservoirs. This work studied the mite fauna of upper and lower faces of 57 mattress from the city of Campinas, state of São Paulo, Brazil. Also, it was studied the HOM immediate Sensitivity in 124 atopic patients, using B.

22. Acute lung function response to cotton dust in atopic and non-atopic individuals.
Acute spirometric responses to inhaled cotton dust were examined in a population of 226 healthy, non-asthmatic adults whose atopic status had been evaluated by skin prick tests to 10 common environmental allergens. Exposure to cotton dust occurred in model cardrooms where elutriated dust levels were carefully controlled (1.02 mg/m3). Atopy, defined as positi

23. Respiratory symptoms, lung function, and sensitisation to flour in a British bakery.
A survey of dust exposure, respiratory symptoms, lung function, and response to skin prick tests was conducted in a modern British bakery. Of the 318 bakery employees, 279 (88%) took part. Jobs were ranked from 0 to 10 by perceived dustiness and this ranking correlated well with total dust concentration measured in 79 personal dust samples. Nine samples had

24. Immunological and respiratory changes in coffee workers.
Immunological status and respiratory function were studied in a group of 45 coffee workers. Skin tests with coffee allergens demonstrated the highest percentage of positive reactions to dust collected during emptying bags (40.0%), followed by dust of green (12%) and then roasted coffee (8.9%). Among 34 skin-tested control workers, 14.7% had positive skin rea
