Desensitive treatment of 102 cases of allergic rhinitis caused by allergens has been carried out using acupuncture endermic points of the head with the extract of positive allergen (or allergens). After two courses of the treatment, the extract of allergens was taken again to make intradermal injection. Diameter of redness and swelling on the skin was significantly reduced in comparison with that before the treatment (P less than 0.01). Cell mediated and humoral immunity of the patients tended to be normal. These cases were followed up for 2 years. 72.18% of the cases had significantly curative effect; 23.56% turned better. Comparison of curative difference of this group with the other two control groups was significant (P less than 0.01).
