Confirming the Effects of Qinghuayin against Chronic Atrophic Gastritis and a Preliminary Observation of the Involved Inflammatory Signaling Pathways: An In Vivo Study

Figure 1

Representative images of the gastric mucosa in the different groups of rats. In the control group, the rats who underwent no treatment (Intact) and those who were administered high-dose QHY treatment (HT) exhibited normal gastric mucosa. Their glands were shaped normally, and there was no atrophy of the gastric glands or intestinal metaplasia. In the model group rats that were not given any treatment (Intact), there was obvious atrophy of the gastric glands and intestinal metaplasia (arrows). However, the group that underwent treatment with low-dose QHY (LT) and high-dose QHY (HT) showed improvement in the pathological manifestations. No intestinal metaplasia was observed, and the gastric glands were thicker than those of the model group (areas in the white frame). Black bar = 1,000 μm.
