近年来,欧美发达国家过敏性疾病,如花粉热、过敏性哮喘等患病人数渐增,发作的严重程度愈演愈烈,甚至造成患者死亡。虽然在一些发展中国家,如我国,过敏性疾病的状况还不很严重,但也呈逐年上升趋势,尤其在一些较发达的城市。有研究表明,寄生虫对过敏有一定的抑制作用,已有人将其用于抗过敏治疗。寄生虫抑制超敏反应的免疫学机制主要有两个方面:(1)寄生虫作为过敏原,能提高人体免疫耐受性;(2)寄生虫可刺激宿主产生一些物质以抑制或缓解超敏反应。由此,研究利用寄生虫进行抗过敏治疗,确有科研和实用价值。
In recent years, developed countries in Europe and the United States allergic diseases, such as hay fever, allergic asthma and other diseases gradually increased, the severity of the attack intensified, and even cause death in patients. Although the situation of allergic diseases is not serious in some developing countries such as ours, it is also on the rise year by year, especially in some more developed cities. Studies have shown that parasites have some inhibitory effect on allergies, it has been used for anti-allergy treatment. There are two main aspects to the immunological mechanism of parasites in inhibiting hypersensitivity: (1) parasites serve as allergens that enhance immune tolerance in humans; (2) parasites stimulate the host to produce substances that inhibit or relieve hypersensitivity reaction. Thus, the study of the use of parasites anti-allergy treatment, there is indeed scientific research and practical value.
