[Oral Allergy Syndrome Following Soy Milk Ingestion in Patients with Birch Pollen Allergy].

Background: Persons allergic to birch pollen often report oral and pharyngeal hypersensitivity to fruit and vegetables, due to immunological cross-reactivity between pollen and foods. This phenomenon is referred to as the oral allergy syndrome (GAS). Such cross-reactive antigen reactions mainly involve Bet v 1, which is the major birch-pollen allergen, and partially involve birch-pollen profilin Bet v 2.

[A relationship between birch pollen counts and meteorological factors in Sapporo].

Occurrence of airborne pollen in Sapporo has been studied for 19 years during the period between 1995 and 2013. There are wide year-to-year variations in the quantities of birch pollens. A simple linear regression with the least squares method was used for studying correlations between the annual quantities of birch pollens and the meteorological factors.

[Questionnaire about the intake of and hypersensitivity to fruits, vegetables and nuts including birch pollen related foods].

Background: In Hokkaido and Scandinavia, birch pollen allergic persons are common and they often report oral and pharyngeal hypersensitivity to fruits and vegetables (oral allergy syndrome, OAS), because of immunological cross-reactivity. In Scandinavia, nuts as well as Rosaceae fruits such as apples were the foods most often reported to elicit symptoms. On the other hand, nuts are minor foods causing hypersensitivity in Japan.

Sorting nexin 5 of a new diagnostic marker of papillary thyroid carcinoma regulates Caspase-2.

Papillary thyroid carcinoma (PTC) is a well-differentiated endocrine malignant tumor that develops from thyroid follicular epithelium. The tumor represents the most common type of endocrine malignancy; however, its tumorigenesis is not fully elucidated. The aim of this study was to address the functional role of the sorting nexin (SNX) family in PTC because of recent experimental evidence suggesting that the SNX family members actively control endocytotic transportation as well as cell fate.

[Relationship between IgE antibodies to recombinant allergens rBet v 1 and rBet v 2 and food causing oral allergy syndrome in cases of birch-pollen allergy].

Background: Persons allergic to birch pollen often report oral and pharyngeal hypersensitivity to fruit and vegetables, such as apples and peaches due to immunological cross-reactivity, or oral allergy syndrome (OAS) sometimes accompanied by systemic reaction. Such cross-reactive antigen reactions involve Bet v 1, the main birch-pollen allergen, and Bet v 2, birch-pollen profilin. We evaluated the food/antigen relationship.

[Clustering of food causing oral allergy syndrome in patients with birch pollen allergy].

Background: Birch pollen allergic patients often report oral and pharyngeal hypersensitivity to fruits and vegetables such as apples and peaches because of cross-reactivity. This phenomenon, called "oral allergy syndrome" (OAS), is sometimes accompanied by a systemic reaction and is considered to be an IgE-mediated allergy. We evaluated reciprocal relationships between food causing OAS using patient's reports and classified food in patients with birch pollen allergy.

[Relationships between oral allergy syndrome and sensitization to pollen antigen, especially to mugwort].

Background: In order to know the relationships between mugwort pollinosis and oral allergy syndrome (OAS), an etiological study was performed at Muroran City, where mugwort is the most frequent cause of pollinosis.

Methods: Allergic rhinitis patients positive to serum IgE to birch, mugwort or grass pollen visited to the outpatient-clinic of Otorhinolaryngology of Muroran City General Hospital from 1998 to 2002, were studied by a questionnaire concerning a past-history of OAS.

Results: The prevalence of OAS was significantly higher in patients positive to serum IgE antibody specific to birch pollen or mugwort pollen than those negative to each pollen-specific antibody (birch; 54.

[Relationship between pollen allergy and oral allergy syndrome].

We recently evaluated the relationship between pollen allergy and oral and pharyngeal hypersensitivity to fruits and vegetables (oral allergy syndrome) over 8 years (1995 approximately 2002) in Sapporo. 1. Of 843 patients with birch pollen (BP) allergy (CAP score 2 or more), 378 patients (37%) had episodes of oral allergy syndrome (OAS), and the rate in BP allergy was higher than in other allergies.

Expression of neurokinin a receptor mRNA in human nasal mucosa.

In airway tissues, it has been suggested that tachykinins act as the transmitter for afferent sensory nerves which respond to various irritants and may be involved in airway allergic reactions. Three classes of tachykinin receptor have been recognized, denoted NK1, NK2 and NK3, which exhibit preferential affinity for substance P, neurokinin A and neurokinin B, respectively. We used molecular probes to study the gene expression and distribution of NK2 receptor in human nasal mucosa.

[Oral allergy syndrome among patients with birch pollinosis in Sapporo].

We evaluated the relationships between oral and pharyngeal hypersensitivity to fruits and vegetables (oral allergy syndrome) and birch pollinosis in 2003 in Sapporo. 1. Of 153 patients with birch pollinosis (seasonal nasal or ocular symptom and CAP positive [birch pollen CAP score 2 or more]), 65 patients (42%) have episode of oral allergy syndrome (OAS).

[Relationship between birch pollen counts and meteorological factors for 8 years in Sapporo].

Occurrence of airborne pollen in Sapporo was studied for the 8 years between 1995 and 2002. Observations on pollen seasons of cedar, birch, grass, and mugwort are presented. There are wide year-to-year variations in quantities of birch pollens.
