Studies on early life viral respiratory infection and subsequent atopic disease in childhood have conflicting findings. Animal models show that viral respiratory infection in conjunction with allergen presentation can enhance sensitization. This prospective study assesses the influence of an upper
OBJECTIVE
To determine the rectal temperature response of cattle, following the oral administration of ergot of rye (Claviceps purpurea), under pen conditions of enforced sunlight compared with those of enforced shade.
METHODS
Hereford cross steers were divided into two groups of 18. One group was
In order to evaluate the effect of immunotherapy on subpopulations of lymphocytes, peripheral blood mononuclear cells were fractionated into T and non-T cells by incubating in anti-immunoglobulin-coated plates. T cells were further fractionated into rye grass antigen-adherent and nonadherent
Skin reactivity to 8 common grass pollens was investigated in patients with hay fever using commercial, unfractionated extracts in serial dilution technique. The highest degree of sensitivity was observed for cocksfoot, meadow fescue, meadow foxtail, rye grass, timothy and Yorkshire fog. Five of
Nasal sensitivity to rye grass pollen allergens was evaluated by provocation testing in patients with hay fever due to grass pollen using measurements of nasal airways resistance (NAR), a reproducible system for delivery of allergen, and stringent criteria for allergen storage. Reproducibility was
On the basis of their 9-year-long allergological and aeropalinological studies the authors examined if the allergen spectrum of their hay fever patients in connection with the seasonality of the symptoms and the pollen count of these 9 years has changed or not. The results of the skin prick tests
'Spontaneous' improvement in, or alteration of, allergic symptoms is a common occurrence, and the immunological basis is of interest in attempts to develop effective specific therapy. In the present study we measured levels of serum antibodies to Dermatophagoides pteronyssinus in patients diagnosed
African swine fever (ASF) is an infectious disease of pigs and represents a massive threat to animal health and the pig industry worldwide. The ASF virus (ASFV) is efficiently transmitted via blood and meat from infected animals and can be highly stable in the environment. There is therefore great
The aim of this study was to compare the efficacy of the immunotherapy by Allergovit and Catalet. 699 patient in age 5-56 were desensitized. 213 were given Allergovit: 137 in one season, 56 in two seasons and 20 in three seasons and 484 were given Catalet: 288 in one season, 151 in two seasons and
Previous, placebo-controlled clinical trials with oral hyposensitization in grass pollinosis have been disappointing. Since the results possibly could be explained by too low doses of ingested allergens, the present study was initiated to evaluate the effect of high doses of allergens. Forty-two
We present the case of a 29-year-old farmer with hay fever and atopic dermatitis since adolescence who had developed work-related asthma about 5 years earlier. He was sensitized to grass pollen, wheat and rye flour, dust from the floors of the animal facilities (cows and pigs) and grain barn, and a
OBJECTIVE
Cross-reactivity between grass pollen and grain flour allergens is well known, but their significance in apprentice bakers with primary sensitization to grass pollen is not known.
METHODS
Twenty-five subjects with mild asthma (most of them with hay fever), but without prior occupational
One hundred (100) patients were treated in the Department of Radiation Oncology, James Graham Brown Cancer Center, University of Louisville School of Medicine, from 1980-1994. All patients were evaluated and staged according to the accepted guidelines at the treatment times. All patients were
Fractionation by Percoll density centrifugation of peripheral blood leucocyte cells, from atopic subjects with seasonal hay fever, unmasked IgE-B cell populations whose individual capacities to synthesize IgE in vitro were obscured in cultures of unfractionated B cells. B cell cultures from all six
Rye grass is the major cause of hay fever which currently affects 20% of the population. Lolium perenne group I (Lol p I) is a glycoprotein of 240 amino acid residues, representing the main allergen of rye grass. We have used peripheral blood mononuclear cells (PBMC) from controls and subjects
