ABSTRACT
To investigate the effects of Yupingfeng granule (YPF) on immune factors of the rats with allergic rhinitis (AR) induced by ovalbumin(OVA). OVA 0.3 mg, Al(OH)3 30 mg and saline 1 mL were mixed and intraperitoneally injected for the initial immunization, 4% OVA 200 μg (50 μL) was given to the nose on the 15th day for the second immunization to establish the allergic rhinitis model. Sixty male SD rats were randomly divided into allergic rhinitis(AR) model group, Yupingfeng granule three dose (2.7,1.35,0.68 g•kg⁻¹) groups, control drug Biyankang (0.4 g•kg⁻¹) and normal control group. After 14 days, efforts were made to collect blood from abdominal aorta, and take nasopharynx tissues and fasten them into 10% formaldehyde for a pathological examination. The levels of HIS, IgE, IL-4 and TNF-α in serum were examined by radioimmunoassay, and nasal mucosa tissues were examined by HE staining. According to the results, the levels of HIS, IgE, IL-4 and TNF-α in serum of Yupingfeng granule groups were significantly lower than that of AR model group (P<0.05, P<0.01). Nasal mucosa tissues showed slight morphological changes and inflammatory cell infiltration, with unobvious necrosis. Yupingfeng granule can improve the pathological changes of nasal mucosa tissues, and reduce the production and release of immune factors during allergic rhinitis (AR) process in vivo by OVA, which may be the important curative mechanism of allergic rhinitis.
