BACKGROUND Recent publications have demonstrated that in Güneykent (Turkey), a rose-cultivating area, some workers experience various allergic reactions due to contact with rose or its pollen. CASE REPORT A 47-year-old man, originally from Güneykent although he no longer lived there, suffered perennial rhinitis, asthma and rhinoconjunctivitis in spring related to sensitization to dust mites a...

BACKGROUND Various studies have shown the clinical efficacy of sublingual immunotherapy in grass pollen-induced rhinoconjunctivitis. However, even short-term treatment with grass extracts might cause sensitizations to formerly unrecognized antigens. OBJECTIVE To determine whether the antibody profiles are changing in patients receiving a defined grass pollen extract prior to and during the gr...

BACKGROUND Allergy to short ragweed (Ambrosia artemisiifolia) pollen is a serious and expanding health problem in North America and Europe. Whereas only 10 short ragweed pollen allergens are officially recorded, patterns of IgE reactivity observed in ragweed allergic patients suggest that other allergens contribute to allergenicity. The objective of the present study was to identify novel aller...

This study aimed to evaluate the anti-allergic potential of Echium plantagineum L. bee pollen and to characterize its primary metabolites. The activity of E. plantagineum hydromethanolic extract, devoid of alkaloids, was tested against β-hexosaminidase release in rat basophilic leukemic cells (RBL-2H3). Two different stimuli were used: calcium ionophore A23187 and IgE/antigen. Lipoxygenase inhi...

Mulberry (Morus spp.) is a widespread deciduous tree and its fruit is commonly eaten in Korea and eastern Asia. Some reports demonstrate that mulberry fruit is a food allergen in the Mediterranean area. However, there has been no report of systemic allergic reactions after ingesting mulberry fruit in Korea. An 18-year-old boy with a mulberry fruit allergy visited our allergy clinic. He had expe...

PURPOSE The sensitization rate to Japanese Hop (Hop J) in respiratory allergy patients has increased in recent years in Korea. We evaluated changes in the allergenic potency of Hop J pollen collected in 1998 and 2009. METHODS Thirty-five patients with allergic rhinitis and/or asthma were enrolled. Group I included 21 subjects sensitized to Hop J at an initial visit and group II included 14 su...

Objective: Hard envelope of date palm pollen is used as a sedative and calmative compounds in Iranian traditional medicine. We tried to study the effects of Phoenix dactylifera (Tarooneh) extract on sleep time and Brian waves. Materials and Methods: Rats were divided into control and test groups in sleep experiment. Control groups included intact group (without any injection), negative control ...

Case 1 Thirty one years old male that presented at age 15 allergic rhinoconjunctivitis and cutaneous pruritus after ingestion of honey and spices. Three years later, he had the same symptoms with ingestion of pepper. Skin prick tests were positive to grass, mugwort, dandelion and ragweed pollen, as well as pepper, curry, paprika and anise. Serum specific IgE was positive to carrot, pea, white b...

Microorganisms and helminthes can cause serious diseases in humans as well animals. The use of antimicrobial antihelminthic drugs have created selective pressure caused resistance to antibiotics used against them, thus it necessitates the honey bee’s derived natural products. One such bee product is pollen, collected by worker bees from flowering plants modify adding its salivary secretions. pr...

BACKGROUND Employees in strawberry greenhouses are highly exposed to several (potential) allergenic agents. However, no occupational allergy in this branch has been described before. First, the presence of work-related allergic symptoms in strawberry workers was explored. Second, we aimed to prove the concept that an IgE-mediated allergy could be responsible for work-related symptoms. To test t...
