2.7. Statistical analysis
All data were expressed as mean standard error of mean (SEM)
value. Statistical analysis was carried out using SPSS (v. 12.0 for
Windows). The statistical significance of the data was determined
using one-way analysis of variance (ANOVA). Post-hoc least
significance test (LSD) paired comparisons were further made in
order to recognize deviant groups. The statistical difference was
regarded at p value < 0.05.
