The Effects of Saposhnikovia divaricata Aqueous Extracts on the Inflammation and Intestinal Microflora in Allergic Rhinitis Mice

Figure 1

The effects of SD treatment on allergic rhinitis of AR mice. (×400) SD reduced the number of (a) sneezing and (b) rubbing noses in AR mice ((n) = 8). (c) The histopathological changes of the nose in AR mice were observed by H&E stain, which was scored according to the degree of a dense arrangement of cells and the degree of mucosal swelling. The score was proportional to the degree of injury ((n) = 6). (d) The number of goblet cells in the AR mice nose was observed by PAS stain, which was proportional to the semiquantitative score ((n) = 6). (e) The number of mast cells of the nose in AR mice was observed by TB stain. The mast cells are dark purple ((n) = 6). All error bars represent mean ± standard deviation. , compared to the control group; , compared to the AR group.
