Objective:
To investigate whether recuperating lung decoction (RLD) can modulate the composition of gut microbiota in rats during asthma treatment.
Methods:
Fifteen Sprague-Dawley rats were divided randomly and equally into control group, model group, dexamethasone (DEX) group, RLD medium-dose group, and RLD high-dose group. The asthma model was established in all groups, except for the control group. The rats in the DEX and RLD groups were treated orally with DEX and RLD, respectively. The rats in the control and model groups were treated orally with 0.9% saline. The intestinal bacterial communities were compared among groups using 16S rRNA gene amplification and 454 pyrosequencing.
Results:
The microbial flora differed between the control and model groups, but the flora in the RLD groups was similar to that in the control group. No significant differences were observed between the RLD high-dose and medium-dose groups. RLD treatment resulted in an increase in the level beneficial bacteria in the gut, such as Lactobacillus and Bifidobacterium spp.
Conclusion:
Oral administration of RLD increased the number of intestinal lactic acid-producing bacteria, such as Lactobacillus and Bifidobacterium, in asthma model rats.
