BACKGROUND
Allergic rhinitis involves inflammation of the nasal passages. The use of nasal steroids is generally very effective in providing significant symptom relief. However, compliance for their use is sometimes poor.
METHODS
To examine the efficacy of early intervention (before pollen
BACKGROUND
Japanese cedar (Cryptomeria japonica) is the most important pollen causing pollinois during spring. During recent years some patients' nasal symptoms have been getting worse after the Japanese cedar pollen season. Japanese cypress (Chamaecyparis obtusa) pollen is also observed in this
To determine the importance of silkworm moth allergens, we tested 267 patients with allergic rhinitis with CAP-RAST, a new assay system for detecting specific IgE in sera. We used the following allergen sources: house-dust mite, Candida, Alternaria, cat dander, orchard grass, ragweed, mugwort,
Clinical characterization of patients with allergy to Chamaecyparis obtusa (Cypress) pollen and their specific IgE antibody was investigated by using AlaSTAT assay, a new method for measurement of antigen-specific IgE antibody. Positive rate of antigen-specific antibody in patients with allergic
The present study aims to investigate the immunomodulatory effects of essential oil from Chamaecyparis obtusa (EOCO) in an ovalbumin (OVA)-induced allergic rhinitis (AR) mouse model. BALB/c mice were intraperitoneally sensitized and stimulated with OVA. From day 22 to 35, 0.01% and 0.1% ECOC
BACKGROUND
About one-third of the Japanese population suffers from Japanese cedar pollinosis, which is frequently accompanied by Japanese cypress pollinosis. Recently, a novel major Japanese cypress pollen allergen, Cha o 3, was discovered. However, whether a Cha o 3 homolog is present in Japanese
Recent observations have suggested significant worldwide increase in the prevalence of allergic rhinitis and cedar pollinosis. In Japan, Japanese cedar (Cryptometria japonica) and Japanese cypress (Chamaecyparis obtusa) pollens are considered to be the major unique allergens and their extent of
BACKGROUND
Japanese cypress pollen is a major causative allergen of seasonal allergic rhinitis in Japan. Although ImmunoCAP-specific immunoglobulin E (IgE) reagent Japanese cypress pollen has been widely used as a diagnostic aid, its sensitivity requires enhancement. This study evaluated an improved
Pollen of Chamaecyparis obtusa (Japanese cypress) is one of the causes of allergic pollinosis in Japan. A major allergen of the pollen designated Cha o 1, was purified by two-step ion exchange chromatography. Cha o 1 was separated into four components with molecular masses of 48.5 kDa and 52.0 kDa,
In Japan, pollen of Cryptomeria japonica and Chamaecyparis obtusa are a yearly source of distress for many people suffering seasonally from allergic rhinitis. To study common epitopes shared by the two species, two monoclonal antibodies (moAbs) were raised against Cry j 1, which is the most
Background: Essential oil derived from Chamaecyparis obtusa (EOCO) has been used as an alternative treatment for allergy-related diseases due to its immune-modulating characteristics. Clothing has the longest and most intense contact with
Chamaecyparis obtusa essential oil (COE) has been widely used to treat allergic diseases and was suggested to exert anti-inflammatory, antioxidant, and antimicrobial effects. This study evaluated the effects of COE on pain-related behavior and pro-inflammatory cytokines in rats with carrageenan
In view of recent studies on the mechanisms of the survival of peripheral memory T cells, we tested the biologic role of pectate lyase, a pectin-degrading enzyme, as the cross-reactive antigen required for the recurring survival signals for human T cells specific for Cha o 1, a pollen allergen
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
