ligustrum delavayanum/hypersensitivity

Cross-reactivity between pollen extracts of four species of Oleaceae was studied: olive (Olea europaea), ash (Fraxinus excelsior), privet (Ligustrum vulgare), and lilac (Syringa vulgaris). Thus, 51 patients and 13 atopic controls were studied, by means of intracutaneous skin tests, histamine-release

In a clinical investigation, 103 Michigan residents with symptoms suggestive of allergic rhinitis or asthma were skin tested with olive (Olea europaea) pollen extract. Nineteen had positive reactions. Since the olive tree is not native to nor grown in Michigan, this study was undertaken to determine

BACKGROUND Ligustrum spp. are members of the Oleaceae family, one of the most prominent allergic families worldwide. The genus Ligustrum contains approximately fifty species, including Ligustrum lucidum, which have been widely cultivated as ornamental plants, and its pollen is a source of inhalant

BACKGROUND Privet pollen rarely accounts for more than 1% of the annual total of daily pollen concentrations measured in a city; however in areas where these trees are widely used as ornamentals the amounts collected may be high enough to cause allergy symptoms. METHODS Air samples taken with

In this paper we present the results of volumetric sampling of the airborne pollen grains of the Oleaceae family (Fraxinus, Ligustrum and Olea) in some European towns, in the period from 1982 to 1986. The sampling and appraisal of pollen content in the air is of particular interest to clinicians and

Three major pollen allergens from Fraxinus excelsior, Ligustrum vulgare and Syringa vulgaris belonging to the Oleaceae family were purified. Monoclonal antibodies previously raised against the main allergen of Olea europaea (Ole e I) were used for their purification by affinity chromatography. The

Ole e I is the major allergen derived from olive tree pollen (Olea europaea) and it is composed of two polypeptides with molecular weights (MWs) of 18 and 20 kD. A panel of six monoclonal antibodies (mAbs) has been prepared and used to map antigenic determinants on this molecule. Four epitope
