Figure 2: LDH released in KB cells untreated and treated for 72 h with Chilean propolis ethanolic extract (80 μg/ml) in the presence or absence of 10 μM SnCl2 or 15 μM SnMP. Each value represents the mean ± SD of three separate experiments performed in duplicate. (* p<0.001 vs. Control; ** p<0.001 vs. Propolis).
