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

Table 4

Average IC₅₀ of H₂O₂ for H9c2(2-1) cells. The IC₅₀ value was determined from respective cell viability curves (Figure 6) via GraphPad Prism (GraphPad Software, Inc., USA). Data represent mean standard deviation of 3 technical replicates (). “” denotes significant difference from negative control treated with media + 1% EtOH at . Graphical representations of data were depicted in Figure 5.
