Abstract:
Objective To observe the effect of panaxadiol saponins (PDS) on intellectual decline and cerebral lesion induced by destabilization of cervical vertebra in mice.Methods44 mice were randomly divided into the normal control group, model group, high PDS doses group and low PDS doses group with 11 animals in each group. The model of destabilization of cervical vertebra was established by operating and intraperitoneal injection of PDS performed in the PDS high doses group (14 mg/kg) and low doses group (7 mg/kg) once everyday for 50 days. The memory ability of mice was evaluated by the water-maze test and tittup platform experiment. 50 days later, all mice were executed and the activities of superoxide dismutase (SOD), lactic dehydrogenase (LDH) and the content of maleic dialdehyde (MDA), nitric oxide (NO) in encephalon were tested.ResultsIn the PDS groups, the incubation period and error times in water-maze test shortened significantly ( P<0.05), aod the reaction period in tittup platform experiment shortened and wrong times decreased obviously ( P<0.01) compared with the model group. The activities of SOD, LDH increased ( P<0.01), and the content of MDA and NO decreased ( P<0.01, P<0.05) in the PDS group compared with the model group.ConclusionPDS has certain protective and improving effect on the decline of memory ability and cerebral lesion induced by destabilization of cervical vertebra in mice.
