Abstract: | Experimental mixed allergy to staphylococcal antigens in guinea pigs was treated by the intranasal administration of a staphylococcal allergen with a surfactant or glycerin added. The treatment was found to produce a hyposensitizing effect with respect to immediate and delayed hypersensitivity. The addition of glycerine enhanced this effect. At the same time the level of T-lymphocytes in the lungs and the lymph nodes of the respiratory tract returned to normal. Detergent used at a concentration of 2% abolished the hyposensitizing effect of the allergen, stimulated T-lymphocytes in the lymph nodes of the respiratory tract and the lungs; the number of T-suppressors decreased. |
