One-way ANOVA was used to compare results (p ≤ 0.01 was considered to be statistically significant).
*Values significantly higher than the Control value (p < 0.01).
aSignificantly different from the R2 and R3 results.
bSignificantly different from the R2 and R3 results.
HSignificantly higher than the remaining results.
LSignificantly lower than the remaining results.
ASignificantly different from the remaining results.
