Effects of Mineral Chinese Medicine Chloriti Lapis on Gut Microbiota of Small Intestine in PTZ-kindling Epileptic Rats

Background: Epilepsy is a neurological disease, and its clinical treatment presents a significant medical challenge. Nevertheless, Chloriti Lapis (CL), a traditional Chinese Mineral Medicine, has been employed for centuries to address neurological disorders and has shown notable effectiveness. Objectives: The objectives of this study are to further explore whether CL can modulate the abundance and diversity of the small intestinal flora in rats with epilepsy induced by pentylenetetrazol (PTZ) and to investigate the interrelationship among the flora. Materials and Methods: Operational taxonomic units (OTUs), alpha diversity, beta diversity, hierarchical clustering tree, and principal component analysis (PCA) were utilized to analyze the small intestinal flora of PTZ-kindled epileptic rats. Results: The predominant bacterial groups in the small intestine mainly belonged to the phyla Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes. The administration of CL was found to effectively increase the abundance and diversity of the small intestinal flora, modify its structural composition, reduce the relative abundance of PTZ-elevated microflora, and enhance the abundance of Streptococcus, Staphylococcus, and Gemella Berger. Conclusion: CL exhibits promising potential, reliability, and unique value in managing epilepsy through the regulation of intestinal flora.
