Analysis of the stimulation under oxidative stress conditions on CCF-STTG1 cells. (a) cell viability (percentage increased), (b) ROS production, and (c) NO production measured on CCF-STTG1 cells pretreated with H₂O₂ 200 μM and then treated for 24 hr with the agents alone and MIX are illustrated. H₂O₂ = 200 μM H₂O₂; H₂O₂ + green tea = 200 μM H₂O₂ + green tea titrated 40% EGCG = 100 μM; H₂O₂; H₂O₂ + saffron = 200 μM H₂O₂ + saffron titrated 0.3% crocin = 25 μM; H₂O₂; H₂O₂ + citicoline = 200 μM H₂O₂ + 100 µM citicoline; H₂O₂ + trans-R = 200 μM H₂O₂ + 1 µM trans-R; H₂O₂ + MIX = 200 μM H₂O₂ + green tea 100 μM + saffron 25 μM + citicoline 100 µM + trans-R 1 µM. The results are expressed as mean ± SD (%) of 5 independent experiments performed in triplicates normalised to control (0% line).  ^∗p < 0.05 vs. control; ^#p  < 0.05 vs. H₂O₂; ^φp  < 0.05 vs. green tea, saffron, citicoline, and trans-R.
