Abstract: AIM: To study the synergistic protective effect of picroside Ⅱ and NGF for the oxidative stress on PC12 cells induced by hydrogen peroxide (H2O2). METHODS: The fluorescent probe 6-carboxy-2', 7' -dichlorodihydrofluorescein (CDCFH) was used to assess the intracellular reactive oxygen species (ROS) level, and MTT assay, morphological observation as well as lactate dehydrogenase (LDH) leakage were conducted to measure cellular injury. RESULTS: The H2O2-induced cytotoxicity was significantly attenuated in the presence of picroside Ⅱ (25 μg/mL) and NGF (2 ng/mL).Cultures with this combined treatment possessed decreased level of ROS while increased cell survival, as compared to that of picroside Ⅱ or NGF alone-treated cells.Accordingly, it was concluded that their synergistic protective activities against oxidative stress in vitro were demonstrated in various aspects including reversing morphological changes, enhancing the ability of cell proliferation and ROS scavenging. CONCLUSION: Such action supports the therapeutic potential of picroside Ⅱ and NGF in treating nervous disorders based on their synergistic effect.
