Abstract:
BACKGROUND: Mugwort is the important source of fall allergic symptoms in the Mongolia. Mugwort pollen allergicpatients frequently present allergic symptoms of ingestion after several kinds of foods.OBJECTIVE: We sought to study the clinical manifestations of airag (fermented mare’s milk) and mare’s milkhypersensitivity in patients with mugwort allergy, identify the molecular weight of allergens, andevaluate their IgE cross-reactivity.MATERIAL AND METHODS: We collected to mugwort pollens from around UB in august and practiced fresh airag and mare’s milk.Airag, mare’s milk and mugwort extracts prepared by Hames Richmond method and their allergenswere identified by means of SDS-PAGE. ELISA inhibition experiments were done to study crossreactivitybetween airag and mugwort.RESULTS: In SDS-PAGE determined mugwort allergen 12-43 kDa, mare’s milk allergen 13-70 kDa, airag allergen12-68 kDamolecular weight.The study of the cross-reactivity between mugwort allergens and some food allergens was becamepractical significance on diagnosis, treatment and prevention of respiratory allergies. We were definedallergenic cross-reactivity between airag allergens and mugwort allergens which are common causesof upper respiratory allergy. On the Mugwort-ELISA inhibition test, the 50 % inhibitory dose to MugwortspecificIgE was 0.01μg/ml Mugwort allergens and 0.025μg/ml Airag allergens.However, the 1.0 μg/mlof Mugwort and Airag allergens were completely inhibited to Mugwort-specific IgE and Airag-specificIgE antibodies.CONCLUSION: In determined the mugwort pollen has 5 band(12, 23, 28, 38, 43kDa), in mare’s milk (13, 15, 60, 70кДа) and airag(12, 30, 50, 68 кДа) has separately 4 bands allergen protein by SDS-PAGE. ELISAinhibition study was strong cross-reactivity between airag allergen and mugwort allergen.
