Fig. 4. Astilbin ameliorates hypoxia/reperfusion (H/R) induced injury of SH-SY5Y cells. (A) The relative cell viability measured by the CCK-8 method. (B) The activity of LDH in SH-SY5Y cells. (C) The activity of MDA in SH-SY5Y cells. (D) The relative mRNA expression of TNFα, IL-1β and IL-6 analyzed by RT-PCR. (E) The level of TNFα, IL-1β and IL-6 analyzed by ELISA. **p < 0.01 vs. sham, ^##p < 0.01 vs. I/R group.
