Protective Effects of Acteoside on PC12 Cell Injury Induced by Glutamate / 医药导报

ABSTRACT

Objective To investigate the effect of acteoside on injury PC12 cells induced by glutamate. Methods PC12 cells were assigned into normal control group, model control group, positive drug group and acteoside(AS) treated group. Every group was treated by 1. 5 mmol·L-1 glutamate for 24 hours except for the control group, and the injury was antagonized by 10 μmol·L-1 Vit E and acteoside at different concentration(15. 625, 31. 25, 62. 5, 125 and 250 μmol·L-1 ). Cell morphology was observed by inverted microscope, cell survival was determined with MTT, LDH activity was measured by enzyme label kit, the MDA content and SOD activity were measured by TBA kit and WST kit, and the ROS was measured by Elisa kit. Results Compared with the model control group, all doses of acteoside could significantly improve the PC12 cell morphology and survival (P<0. 05), inhibit LDH activity and production of MDA and ROS (P<0. 05), increase the activity of SOD (P<0. 05), except for the lowest dose group. Conclusion Acteoside has protective effects on PC12 cells injured by glutamate.
