Fig. 5 — (A) Results of the extract antioxidant activity level of A. platensis in various concentrations: statistical analysis showed that there was no significant difference between different concentrations except for the 125 μg/ml and 500 μg/ml. (B) The amount of DCFH produced in two experimental cell lines (A549 cells compared to HFF cells). Control groups and treated with IC50 concentration of S. platensis extract at 24 h (P ≤ 0/01). (C) The amount of malondialdehyde produced in A549 cells compared to HFF cells treated with IC50 concentration of Spirulina extract at 24 h (p ≤ 0.001). (D): Releases of LDH in HFF and A549 cells treated with algal extract in compare to control group (without extract).
