Learning and memory abilities were detected with water maze test and superoxide dismulase(SOD) activities and malondiadehyde (MDA) contents in the liver and brain were determined after intragastrical administration of Shenlong Decoction (参龙汤) for 6 weeks. The results indicated that the swimming time was shortened and the correct swimming times increased, SOD activity raised and MDA content decreased in the three Shenlong Decoction groups with different doses as compared with the model group. It is concluded that Shenlong Decoction has the effects of anti-free radical injuries and improving the learning and memory abilities of the brain-aging mice induced by D-galactose.展开更多
In order to study the molecular mechanism of D-galactose induced aging model, cDNA microarray is used to analyze gene expression profiles of both normal and D-galactose induced aging model rats. D-galactose induced ag...In order to study the molecular mechanism of D-galactose induced aging model, cDNA microarray is used to analyze gene expression profiles of both normal and D-galactose induced aging model rats. D-galactose induced aging model rats are injected with D-galactose, while normal rats are injected with physiological saline as control. After 7 weeks, the two groups of rats are killed simultaneously. Their livers are harvested for genome-wide expression analysis. D-galactose treated rats showed changes in gene expression associated with increase or decrease in xenobiotic metabolism, protein metabolism and energy metabolism.展开更多
