And the severity of skin prick test reactions to cow's milk and egg was the predicting factor for persisting hypersensitivity to cow's milk and egg (OR=2.535,95%CI:1.159—5.543;OR=2.654,95%CI:1.302—5.410,P<0.05).
After 4 cases and 15 cases were diagnosed as allergic rhinitis and asthma, respectively, (16.8±8.3) months after diagnoses and the risk factors were the long-lasting hypersensitivity to egg and the respiratory symptoms (OR=3.596,95%CI: 1.429—9.045; OR=4.235,95%CI: 1.152—15.563,P<0.05).
In classical contact hypersensitivity, Thl cellsproduce interleukin-2 (IL-2), interferon- y (IFN- y) and tumornecrosis factor- 13 (TNF- 13), which contribute to CH, whereas Th2cells produce JL-4, IL-5, JL-13, by which CH is negativelyregulated.
Inhalation of environmental allergens from pollens、mites、insects and fungi induces IgE antibody responses, which can cause immediate hypersensitivity reactions and may result in the development of allergic diseases such as rhinitis, asthma and atopic dermatitis in genetically susceptible individuals.
DNase Ⅰ hypersensitivity is known to be associated with potentiallyactive genes, When the reaction was detected by DNase Ⅰ in situ nick translation, aD-like banding pattern was produced on pachytene bivalents of Rice-field Eel.
Emphasis is placed on the mechanisms whereby plants are protected from nematode invasion (hypersensitivity reactions, apoptosis, phytoalexins, proteinase inhibitors, PR proteins, etc.).
The development of hypersensitivity response proved to be accompanied by a complex spatial and temporal distribution of lectin activity.
HeLa cells obtained as a result of Bax transfection and subsequent selection are characterized by an extremely high Bax protein content and a hypersensitivity to doxorubicin.
The derivatives with Cys(Bzl) and Cys(Bzl)-Val residues attached to the carbohydrate part of the molecule stimulated the primary immune response and the reaction of delayed-Type hypersensitivity in mice at a dose of 2 mg/kg.
All the studied compounds had practically no effect on the delayed-type hypersensitivity in mice.
