468 Urticarial Vasculitis After Bee-sting Therapy June-Hyuk Lee, Sung Woo Park, An-Soo Jang, DoJin Kim, and ChoonSik Park. Respiratory and allergy, Soonchunhyang University Bucheon Hospital, Bucheon, South Korea; Division of Respiratory and Allergy Medicine, Soonchunhyang University Hospital, College of Medicine, Bucheon, South Korea. Background: Bee-sting therapy is one of the oriental traditional medical therapies. Some chemical components of bee venom have been known to have anti-inflammatory effects. Recently, traditional therapists use one chemical component (e.g. Apitoxin) for injection therapy using a syringe, instead of sting method with bee itself as to be known traditional method. 31year-old woman had a lower back pain because of mild HIVD in lumbar spine for 5 months. She had bee-sting therapies for several times for 4 months. During this period, she didn’t have any side effects and pain was improved. Her back pain recurred 4 weeks ago and had bee-sting therapy again. The traditional doctor performed intramuscular injections of 1 mL of Apitoxin on her lower back muscle. After 4 days, reddish skin lesions and swelling developed on her legs and spread to trunk. She was transferred and treated with systemic corticosteroid and antihistamine. Methods: Serum speicific IgE and IgG were measured by immunoCAP for and skin biopsy performed accompanied with managements. Results: High levels of specific IgG but negative of IgE to honey bee venom were observed by immunoCAP. Skin biopsy was revealed as an urticarial vasculitis. Conclusions: We report the case that suspicous to be serum sickness developed after bee-sting therapy.

Vig r 6, the cytokinin-specific binding protein from mung bean (Vigna radiata) sprouts, cross-reacts with Bet v 1-related allergens and binds IgE from birch pollen allergic patients’ sera
SCOPE Birch pollen associated allergy to mung bean sprouts is caused by cross-reactivity between the birch pollen allergen Bet v 1 and the mung bean allergen Vig r 1. We aimed to determine the allergenicity of the cytokinin-specific binding protein from mung bean (Vig r 6), another allergen related to Bet v 1 with only 31% sequence identity. METHODS AND RESULTS Bet v 1, Gly m 4, Vig r 1, and ...

Background: Mung beans (Vigna radiata) contain 2 Bet v 1 related proteins: Vig r 1, a member of the PR-10 subfamily, and cytokinin-specific binding protein (CSBP), a protein with low sequence identity (31%) to Bet v 1. We aimed to compare Vig r 1 and CSBP to Bet v 1 regarding biochemical and immunological properties. Me...

متن کاملRandom mutagenesis and phage display technology as a tool for identifying ige epitopes of the birch pollen allergen Bet v 1
Background IgE-binding epitopes of the major birch pollen allergen Bet v 1 are dependent on the native structure of the allergen. To date, only a single IgE epitope has been identified. We aimed to identify additional epitopes by directed in vitro evolution of non-IgE-binding structural homologues to proteins carrying single IgE-binding patches. For that purpose, we chose cytokinin-specific bin...
