STUDY OF THE PROPERTIES OF THE MIXED WATER/SALT HOUSE DUST MITE ALLERGEN AIMING TO DESIGN ITS SUBLINGUAL FORM
Сurrent allergen-specific immunotherapy (AIT) is the most pathogenetically justified method of the IgE-dependent treatment of allergic diseases. Subcutaneous (SCIT) and sublingual (SLIT) AIT are currently used in wide clinical practice. Sublingual immunotherapy is characterized by the convenience of...
