Effects of Desmodium caudatum on Gastrointestinal Hormones and Intestinal Flora in Rats with Gastritis

In order to preliminarily explore the effects of Desmodium caudatum on gastritis and intestinal flora in rats, a chronic gastritis rat model was established using the classic sodium salicylate method. Eighteen SPF rats were divided into three groups: the control group (Group C), the model group (Group M), and the treatment group (Group T). Pathological sections of the gastric wall were taken from rats in each group. Furthermore, the concentrations of gastrin and malondialdehyde in the serum of rats in each group were determined by ELISA. Additionally, the effects of D. caudatum on the intestinal flora of rats with gastritis were explored through a detailed comparison of gut bacterial communities in the three groups, employing Illumina-based 16S rRNA gene sequencing. The results indicated that D. caudatum decoction could reduce the malondialdehyde content and increase the gastrin content. Moreover, D. caudatum decoction was found to enhance the diversity and abundance of intestinal flora, exerting a positive impact on the treatment of gastritis by regulating and restoring the intestinal flora.
