Cortex cinnamomi extract prevents streptozotocin- and cytokine-induced β-cell damage by inhibiting NF-κB

Figure 5 Effect of CCE on cytokine-induced NO production in RINm5F cells. RINm5F cells (5 × 10⁵) were treated with cytokines with or without the indicated concentrations of CCE. The concentrations of cytokines used were same as those in Figure 4. Following 24 h of incubation, nitrite concentrations (indicative of NO synthesis) were measured in cell-free culture supernatants. Results of triplicate samples are expressed as means ± SE of four independent experiments. ^bP < 0.01 vs control; ^dP < 0.01 vs cytokines.
