Abstract

The invention relates to a method for constructing an allergic rhinitis model in a non-human mammal by using the pollen of Cryptomeria fortunei, belonging to the field of construction of animal models of allergic rhinitis. The pollen of Cryptomeria fortunei (Cryj1) is used as an allergen, and a solution containing Cryj1 is dripped into the nostrils of a non-human mammal so as to construct a model for allergic pollen, wherein the non-human mammal is a mouse. The allergic rhinitis model in the non-human mammal is successfully constructed in the invention, and the model realizes abnormal proliferation of epidermal goblet cells in the nasal cavities and increased secretion of mucus.

Description

technical field [0001] The invention relates to the field of constructing allergic rhinitis animal models, in particular to a method for constructing non-human mammalian allergic rhinitis models using cedar pollen. Background technique [0002] Allergic rhinitis (allergic rhinitis, AR) is an allergic disease that occurs in the nasal mucosa due to the increased sensitivity of the body to certain allergens. It is a common and frequently-occurring disease among respiratory diseases. According to European and American statistics, the incidence of allergic rhinitis has increased by about 30% in the past 10 years. With the development of industrialization in my country, the incidence of allergic rhinitis is also increasing, especially in spring and summer. high. [0003] Cedar is a widely used afforestation tree species in China and Japan, and it is also planted in Europe, North America, and Nepal and India in the east of the Himalayas. In Japan, the coverage rate of cedar can re...
