In a previous study with airborne mould extracts we verified thatDrechslera (Helminthosporium) monoceras presented stronger reactions than those presented by 42 other moulds isolated in São Paulo city. In the present study, we evaluated the biochemical composition and the antigenicity of crude extracts obtained from vegetative and conidial stage ofD.(More)
In this study, we investigated the fungi most frequently found in the air and the books of 28 libraries at the University of São Paulo, Brazil. In a second phase, 314 librarians were questioned about the presence of asthmatic or rhinitic symptoms, and the relationship with the site of work. Forty-nine percent of them reported this type of symptoms and 80%(More)
Crude extracts of the lipophilic yeast Malassezia furfur were obtained from 2, 6, 10 and 28 day old cultures. The in vitro cultivation periods corresponded, respectively, to the lag phase, middle of the log phase, end of log phase and the decline phase of the growth curve, which was based on viable cell counts obtained with a fluorescent viability test.(More)
The efficacy of nedocromil sodium 4 mg or 2 mg q.i.d. in the management of perennial extrinsic asthma was evaluated in a double-blind, placebo-controlled, multicentre trial. Nedocromil sodium, especially at the dose of 4 mg q.i.d., was consistently rated higher than placebo on clinical assessment and diary card measurement. Compared with placebo, there were(More)
We performed bronchial challenge with ASA lysine in 9 patients with a history of aspirin-induced asthma, 4 asthmatics with no history of hypersensitization to aspirin and 4 control subjects. The test consisted of successive inhalations of increasing concentrations of ASA lysine (11.25, 22.5, 45, 90, 180 and 360 mg/ml) and was interrupted when FEV1 showed a(More)
We've studied the immunological performed of twenty two natives Tikunas suffering from tertiary pinta. Among those, patients had been treated previously (two years earlier) which 2,400,000 IU of G benzathine penicillin, and twelve had no treatment. Both groups demonstrated an increment in the IgM synthesis (72.72%), IgG (50%), indicating the presence of(More)
Metarhizium anisopliae is used as a biopesticide for insects that damage agricultural plantations like sugar cane and forage plants. In a previous study the sensitization to this fungus of asthmatic patients coming from sugar cane areas was showed. The aims of this work were: to compare crude extracts obtained with Tris-HCl and Coca liquid from several(More)
A total of 245 patients submitted to lung function test were studied. They were divided in 2 groups: A--FEV1.0/FVC greater than or equal to 75% and B--FEF25-75% less than 75%. These groups were further subdivided according to the age of the patients--subgroup 1 less than or equal to 50 years and subgroup 2 greater than 50 years. Patients with restrictive(More)
Seventy-eight Brazilian beekeepers who had been stung on average six times per month were studied. Sixty-eight beekeepers (87.1%) showed restricted local clinical reactions; nine individuals (11.5%) had extensive local reactions, and only one (1.2%) suffered anaphylactic shock. The humoral immunologic pattern of these individuals were studied by using(More)
One hundred outpatients in a Clinic of Allergy were submitted to intradermic tests with two types of candidins. The main focus of the research was the comparison of two antigens obtained from the same strains of Candida albicans: one a suspension of yeast cells and the other, a polysaccharide. The readings, taken 20 minutes after the intradermic injections,(More)
