The effect of UTI on PC12 and SH-SY5Y cells. (A) The effect of different concentrations of UTI on cell viability. Concentrations of 0–500 µM UTI had no significant effect on cell viability, while 1,000 µM UTI significantly reduced the cell viability. (B) The effect of different concentrations of UTI on LDH release. Concentrations of 0–500 µM UTI had no significant effect on LDH release, while 1,000 µM UTI significantly increased the LDH of PC12 and SH-SY5Y cells. Since a high concentration of UTI affected the viability and LDH level of PC12 cells and SH-SY5Y cells, 100, 200, and 500 µM UTI treatments were used in subsequent experiments. **, P<0.01. UTI, ulinastatin; LDH, lactate dehydrogenase.
