Cytoprotective and Cytotoxic Effects of Rice Bran Extracts in Rat H9c2(2-1) Cardiomyocytes

Table 3

Cell viability of H9c2(2-1) after inductions with different concentrations of H₂O₂. Cells were pretreated with different concentrations of BJLN and MR219 RBE before H₂O₂ induction. Data represent mean standard deviation of three technical replicates (). “” on each column denotes significant differences at as compared to negative control (nontreated cells).
