juniperus/hypersensitivity

The non-standardized Cupressus sempervirens allergen extract currently available for the diagnosis of cypress allergy has a low level of activity. The search for an active material consisted of in vitro and in vivo comparison of three Cupressaceae pollen extracts: Cupressus sempervirens (Cs),

BACKGROUND Cupressaceae allergy is a worldwide pollinosis caused by several species. Some species in limited geographic areas pollinate in fall and winter. Juniperus oxycedrus matches these features. OBJECTIVE We sought to define the immunochemical, allergologic, and environmental aspects of J.

BACKGROUND Pollen challenge chambers have been used to evaluate medication in allergic rhinoconjunctivitis under controlled conditions. OBJECTIVE To validate a facility for the study of subjects' responses to inhalational challenges with Juniperus ashei (mountain cedar) pollen. METHODS Two chambers,

Allergic diseases have been increasing in industrialized countries. The environment is thought to have both direct and indirect modulatory effects on disease pathogenesis, including alterating on the allergenicity of pollens. Certain plant proteins known as pathogenesis-related proteins appear to be

BACKGROUND Pollen monitoring is a common and vital tool in the field of allergy, creating awareness in pollen sensitive individuals. Traditionally, pollen monitoring has been based on conventional microscopic counting techniques that are labor intensive and limited in the identification to the genus

BACKGROUND Cedar pollens cause allergic disease in diverse geographic areas. We have recently purified and characterized the major mountain cedar (Juniperus ashei) pollen allergen, Jun a 1. OBJECTIVE A full-length complementary DNA for Jun a 1 was cloned and sequenced, and the recombinant protein

BACKGROUND Cedar pollens are important causes of seasonal allergic disease in diverse geographic areas. OBJECTIVE A major allergen from mountain cedar (Juniperus ashei) pollen, termed Jun a 1, was isolated and characterized. METHODS Water-soluble pollen glycoproteins were extracted, salt

OBJECTIVE The aim was to evaluate the impact of Cupressus sempervirens (Cs) and Juniperus communis (Jc) sensitisations in "Maremma" in southern Tuscany. METHODS 811 consecutive outpatients (357 F - 57.86%; age: 36.9 ± 16.6) with suspected allergic respiratory symptoms underwent skin prick tests

BACKGROUND Cedar pollens are important causes of seasonal allergic disease in diverse geographical areas. However, pollens from different families and species vary in their propensity to induce allergic responses. OBJECTIVE To compare the structure of potential allergens from eastern red cedar

BACKGROUND Species belonging to the Cupressaceae family are a relevant source of allergens that are present in a wide number of countries. OBJECTIVE We sought to identify, purify, and characterize recombinant allergens from Juniperus oxycedrus, a species belonging to the Cupressaceae

Pollen from cedar and cypress trees is a major cause of seasonal hypersensitivity in humans in several regions of the Northern Hemisphere. We report the first crystal structure of a cedar allergen, Jun a 1, from the pollen of the mountain cedar Juniperus ashei (Cupressaceae). The core of the

BACKGROUND The safety and efficacy of high-dose sublingual-swallow immunotherapy (SLIT) has been established in pollen rhinoconjunctivitis. This treatment has now been evaluated using an ultra-rush incremental dose regimen with a Juniperus ashei allergen extract in patients allergic to Cupressus

BACKGROUND The efficacy of standardized Juniperus ashei extract was assessed in patients with allergic rhinoconjunctivitis due to European cypress pollens. METHODS Forty adults with European cypress-allergic rhinoconjunctivitis were randomized to receive immunotherapy or a matched placebo. Specific

The essential oil extracts of western juniper oil (Juniperus occidentalis) and Port-Orford-cedar oil (Chamaecyparis lawsoniana) were evaluated for possible dermal toxic effects on mice and rabbits. Mice were tested for their response to both extracts utilizing a local lymph node assay. Western

The diagnostic workup of contact allergy to fragrances must not be limited to patch testing with the two well-established fragrance mixes. False-positive reactions to these mixes occur in up to 50 % of the patch tested patients. For the diagnostic work-up of positive reactions, and in cases of
