Effect of licorice compounds on cell death due to hydrogen peroxide or 3-morpholinosydnonime. PC12 cells were pre-treated with licorice compounds [1~50µM GL (A) or 1~10µM GA (B)] for 15 min, exposed to 200µM hydrogen peroxide for 4 h or 750µM 3-morpholinosydnonime for 24 h, and cell viability was determined. Data represent means ± SEM (n=6). +p<0.05 compared to control; and *p<0.05 compared to hydrogen peroxide (HP) or 3-morpholinosydnonime (SIN).
