Abstract:
The article was aimed to study the influence of low pressure and hypoxia on rat metabolism and evaluate the intervention effect of San-Guo-Tang-San (SGTS) on high altitude polycythemia (HAPC) rats. A total of 25 rats were divided into the plain control group, high altitude model group, Hong-Jing-Tian capsule (Nuo-Di-Kang cap-sule) group, high-dose SGTS group and low-dose SGTS group, with 5 rats in each group. After one week adaptation, rats in the model group and the medication groups were put into the hyperbaric chamber for 40 days (22 h/d) to simulate high altitude environment of 5 000 m. In the end of 40th day, the hemorheology and the dry/wet weight ratio of lung of rats were measured. And plasma samples were derivatized with ECF prior to GC-MS instrumental analysis. Principal component analysis (PCA) was used to find potential biomarkers, and evaluate the intervention effects of SGTS. The results showed that the low pressure and hypoxia changed the hemorheology and dry/wet weight ratio of lung of rats markedly. Metabolomics studies showed that the high altitude model group, high-dose SGTS group, low-dose SGTS group, and Hong-Jing-Tian capsule group can be obviously differentiated. Main markers such as 9-hexylheptadecane, glycine, N-methyl-N-methoxycarbonyl-ethyl ester, 2,4-Di-tert-butylphenol, were found to be the endogenous substances of SGTS which intervening the HAPC rats. It was concluded that SGTS can intervene low pressure and hypoxia induced HAPC.
