Weiwei Decoction alleviates gastric intestinal metaplasia through the olfactomedin 4/nucleotide-binding oligomerization domain 1/caudal-type homeobox gene 2 signaling pathway

Figure 3 Weiwei Decoction improves gastric mucosal histological lesions. A: Timeline of the animal experiments design for Weiwei Decoction treatment; B: Representative hematoxylin and eosin-stained images of the gastric mucosa in each group (n = 3). Vacuolation changes (orange arrow), pyknotic and hyperchromatic nuclei (blue arrow); C: Representative Alcian blue-Periodic acid-Schiff-stained images of the gastric mucosa in each group (n = 3). Blue-stained cavities (yellow arrow). Scale bar: 100 μm. WWD: Weiwei Decoction; FA: Folic acid; HE: Hematoxylin and eosin; AB-PAS: Alcian blue-Periodic acid-Schiff.
