Abstract:
BACKGROUND:Moxibustion products produced in moxibustion, such as moxa smoke, are one of hotspots in moxibustion research. Metabonomics can be used to more comprehensively and systematicaly study the effects of moxibustion products on the body.
OBJECTIVE:To investigate the efect of diferent concentrations of moxibustion products on urine metabonomics of rats.
METHODS:Forty Sprague-Dawley rats were randomly divided into normal control group, low-dose moxibustion products group, middle-dose moxibustion products group, high-dose moxibustion products group, high-dose moxibustion products recovery group. In the latter four groups, rats from each group were exposed to the mixture of moxibustion products and pure gas at ratios of 0.4:2.0, 0.8:2.0, 1.6:2.0, 1.6:2.0, respectively, 4 hours daily, 5 days weekly, totaly for 60 days. After 60-day high-dose moxibustion products stimulation, rats in the high-dose moxibustion products recovery group were raised in normal air for 21 days. Rats in the normal control group were raised in normal air for 60 days without any moxibustion products. Then we analyzed the changes of urine metabonomics in al group rats.
RESULTS AND CONCLUSION: Totaly 108 metabolites were identified in the urine of rats using gas chromatography/time-of-flight mass spectrometry, and 64 metabolites were verified by standard library. There were some positive correlations between changes of typical metabolites and moxibustion product concentrations. The metabolites in the urine were most different between the high-dose moxibustion products group and normal control group. Twenty-two differential metabolites, such as glucuronic acid and vitamin C were mainly involved in 15 sugar and amino acid metabolic pathways, such as ascorbate and aldarate metabolism. These findings indicated that energy metabolism, detoxification and anoxidation increased in rats stimulated by moxibustion products.
