Figure 3

Effect of MFXD on OVA-induced allergic rhinitis in rat. (a) The frequencies of sneezing and nasal scratching of rats were counted for 30 min immediately after the last challenge by nasal instillation with OVA solution on day 31. Blood samples were collected and the serums were obtained by centrifugation. The total IgE (b) and HIS (c) levels in serum were detected by ELISA. The nasal mucosa samples were collected and stained with (d) hematoxylin and eosin (HE) and (e) toluidine blue (TB). Epithelial layer (El), ciliated cell layer (Ccl), leucocytes (represented by black arrows), and mast cells (represented by red arrows) were marked on the images. Data are expressed as mean ± SD; rats; , versus model.
