1.11 Statistical analysis
All analyses were performed in triplicate, and the data expressed as the means ± standard deviation (SD). Statistical analysis was carried out using SPSS program version 19.0. The significant difference among the data was evaluated by One-way Variance (ANOVA) combined with Tukey’s adjustment test. Significant differences were assessed at P ≤ 0.05. Boxplots, line-charts and bar-charts were generated by using Origin 8.5 software.
