[The effect of Wu-He Dipsacus asper on mice-aging model induced by D-galactose].

OBJECTIVE

To study the effect of Wu-He Dipsacus asper (WHDA), Traditional Chinese Medicine, injection on mice-aging model induced by D-galactose.

METHODS

Forty-eight Kunming mice (24 male and 24 female) were randomly divided into control group, model group, positive control group, 7.2 g/kg WHDA group, 3.6 g/kg WHDA group and 1.8 g/kg WHDA group with eight in each group. The model was induced through injecting D-galactose into peritoneal cavity and Morris water maze was used to detect the learning and cognitive ability of mice. The skin hydroxyproline, brain tissue malondialdehyde (MDA), lipofuscin (LP), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels of mice were detected; the IL-2 and IL-6 levels in serum of mice were detected by using double antibody sandwich ELISA method.

RESULTS

Each WHDA group was significantly reduced in latency period compared with the model group during Morris water maze test (P < 0.05) and the number of mice in model group through the platform was less than other mice in each group (P < 0.05). The levels of MAD and LP of the control group and each WHDA group were less than model group in the detection of heart, brain tissue oxidation index (SOD, MAD, LP and GSH-Px, P < 0.05). The activity of SOD and GSH-Px in the control group and each WHDA group was significantly higher than that in the model group (P < 0.05). The skin hydroxyproline content of mice which had been injected with D-galactose was significantly lower than that in the control group (P < 0.05) and the skin hydroxyproline content of mice of WHDA group was significantly higher than that in the model group (P < 0.05). The IL-2, IL-6 levels in serum of mice in WHDA group were significantly higher than those in the control group and the model group (P < 0.05) and the IL-2, IL-6 levels in serum of mice in the model group were lower than those in the control group (P < 0.05).

CONCLUSIONS

The effective constituents of WHDA have a variety of biological activity which can have a good effect on anti-aging by different ways, improving learning and memory function, eliminating free radicals antioxidant, and enhancing the body immunity and other aspects.
