Fig. 1
Percentage change in the parameters indicative of stress response in the groups used for the study. A – mean serum corticosterone level: control versus stress groups and stress + Spirulina platensis versus stress groups; B– effect of supplementation with Spirulina platensis for 28 days on serum total antioxidant capacity; C – total oxidant status; D – paraoxonase 1 in stress-induced rats; E – oxidative stress index in stress-induced rats
All data are presented as the mean ± SD (n = 9); * – P < 0.05 when compared with control rat values; # – P < 0.05 when compared with stress-induced rat values
Fig. 2
Effect of supplementation with Spirulina platensis for 28 days on serum concentrations and percentage change in mean serum of interleukin 2, interleukin 4 and interferon gamma. A – interleukin 2 concentration; B – interleukin 2 percentage difference; C – interleukin 4 concentration; D – interleukin 4 percentage difference; E – interferon gamma concentration; F – interferon gamma percentage difference
All data are presented as the mean ± SD (n = 9)
