**Figure 5. **mRNA expression of intrinsic apoptotic factors such as *caspase-9* (**A**) and *cytochrome-C* (**B**). *β-actin* was used as an internal marker. Statistical significance between the control group versus other groups was considered at
the level of p<0.05 using SNK test. ^{a} represents the statistical significance Group I versus Group II, and ^{b} represents the statistical significance of Group II versus Group III.
