Objective:Investigating the protective effect of CSF of rat administrating FBD orally on various injured PC12 cells models to indicate the mechanism of FBD therapying dementia.Methods:Four injured PC12 models induced by hydrogen peroxide
hydrosulfurous sodium
glutamate and potassium chloride accordingly were used to assay the effect of CSF sample on PC12 cells.Results:It was found that the rat CSF sample at different time points from 0.5h to 2.5h after taking FBD repetitiously (1.62g crude herb·kg -1 ) could obviously increase the viability of PC12 cells injured by hydrogen peroxide
which peaked at 1.5h.The rat CSF containing FBD of 1.5h could also protect PC12 cells injured by hydrosulfurous sodium、glutamate and potassium chloride
and the protection rate increases with the concentration of CSF containing FBD.Conclusion:CSF of rat administrating FBD orally could protect PC12 cells
possibly by antagnizing the overload of calcium
oxidant injury of free radicals and excitatory nerotoxicity of glutamate.
