Abstract:

The aim of this study is to investigate the effects of Ganoderma resinaceum alcohol extract(GRAE)on sleep and intestinal microbiota in mice,and to analyze the association between intestinal microbiota and sleep. The sleep rate and sleep duration of mice under sodium pentobarbital induction were observed by continuously gavaging for 30 d,and the sleep latency of mice induced by sodium barbiturate was observed. The serum of mice was tested and the effect of GRAE on the abundance of intestinal microbiota in the mice was analyzed by 16S rDNA sequencing. The results showed that GRAE prolonged the sleep duration of mice induced by sodium pentobarbital,increased the sleep rate of mice hypnotized by pentobarbital sodium subthreshold dose,shortened the sleep latency of mice induced by sodium pentobarbital,and decreased the serum levels of glucose(GLU)and triglyceride(TG)in mice. 16S rDNA results showed that GRAE increased the abundance of Bacteroidetes and Actinobacteria at the phylum level;at the genus level,GRAE increased the abundance of Bifidobacterium,and decreased the abundance of Lactobacillus and Klebsiella. Therefore,GRAE can regulate the abundance of intestinal microbiota,which in turn affects the sleep quality of mice.
