Tanshinone IIA Attenuates Diabetic Peripheral Neuropathic Pain in Experimental Rats via Inhibiting Inflammation

Figure 4

The effect of Tanshinone IIA on the protein expression of IL-1β, IL-6, TNF-α, and IL-10 in the DRG from experiment rats. The protein levels of IL-1β, IL-6, TNF-α, and IL-10 were determined by Western blot. (a) Western blot results of the IL-1β, IL-6, TNF-α, and IL-10. (b) The target protein bands were densitometrically analyzed after normalization to β-actin. Each experiment was repeated three times and similar results were obtained. CTL, normal rats; DM + Veh, DM rats treated with vehicle; DM + TIIA, DM rats treated with Tanshinone IIA. ( for each group; , versus CTL group; , versus DM + Veh group).
