Impact stilbene glycosides and PNS Concomitantly on AD model PC12 cell injury / 国际中医中药杂志

ABSTRACT

Objective To investigate stilbene glycosides(TSG) and PNS concomitantly on PC12 cell survival rate of Alzheimer's disease.Methods The nerve cells that were seeded on the two culture plates were cultured for 1 day after the removal of primary culture fluid.In addition to the blank group, the model group and drug compatibility group were added 5 μl Aβ25-35 perpore to induced PC12 cell damage.To established AD cell damage model after exposure to the circumstances for 24 hours.Uniform design and factorial design were used respectively.After 1 d, using MTT method in ELISA analyzer measured the OD value of each pore, and calculating the survival rate of cells.Results The uniform design results showed that the cell survival rate was significantly linear with TSG and PNS (P＜0.05).From the equation, The higher the dose, the higher the cell survival rate.In this experimental condition, TSG and PNS respectively 50 mg/L, 200 mmol/L achieved the highest cell survival rate.2×2 factorial design experiments showed that, compared with the model group, the cell survival rate of TSG-PNS group (74.46％ ± 2.06％ vs.65.42％ ± 1.42％) increased (P＜0.05), but there was no interaction between the two groups (P=0.053).This showed that the combination of the two drugs in this dose has a protective effect on AD damage.Conclusion The compatibility of total saponins of two stilbene glucoside and three seven combination has the synergistic effect of anti AD damage.
