The amount of histamine released from blood leucocytes by allergen, the amount of allergen required to release 50% histamine and the total IgE and IgE specific for Dactylis glomerata are compared in nine hay fever patients and five control individuals. The variation with time of total IgE, of
Previous studies of intranasal immunotherapy have not included control groups treated with an irrelevant allergen. In the present double-blind study, we tested the effectiveness of intranasal immunotherapy in 20 patients sensitive to both short ragweed (SRW) and orchard grass (OG). Patients sprayed
This trial of hyposensitisation compares the efficacy and safety of an alum absorbed 2-grass extract (Phleum pratense and Dactylis glomerata) with a traditional pyridine extracted alum precipitated 5-grass preparation whose efficacy has been demonstrated previously. 33 patients, (20 Alpare, 13
A three-year study was conducted to measure the effects of varying levels of dairy slurry application on mineral concentration of forages from three soils types. Slurry was applied to orchardgrass (Dactylis glomerata [L.] cv. Pennlate) growing in 60-cm diameter drainage lysimeters to measure the
An outbreak of ergot, caused by Claviceps purpurea, occurred in barley (Hordeum vulgare) grown in northeastern Iowa and southwestern Wisconsin in 1996. In a nine-county area of intensive dairy production in Iowa, approximately 40% of the barley hectarage (approximately 1,200 ha) was affected by the
Two crop fields (alfalfa and orchard grass) and two fallow fields (bluegrass and old field) were compared on the basis of plant and foliage arthropod complexity. Plant species richness and foliage height diversity increased substantially from crop to fallow: bluegrass to fallow: old field. The trend
A 4-year-old boy was admitted to our department with fever, cough and dyspnoea, unresponsive to salbutamol and antibiotic therapy. He had previously contracted bronchiolitis at 20 days of life, followed by intermittent episodes of wheeze that never required hospitalisation and responded to short
Poor growth often occurs in cattle consuming ergot alkaloids associated with endophyte-infected (EI) tall fescue. Hyperthermia may contribute significantly to poor growth resulting from fescue toxicosis. This study examined indicators of thermal status and growth in Hereford (n = 30; heat-sensitive
