Fig. 9. Photographs (magnification = 40×, scale = 50 μm) shows immunohistochemical expression of NF-κB in MCAO model in control (N), ischemic (I) and treatment groups of collagen–curcumin nanocomposite doses ND1 (1 μg per kg b. wt), ND2 (10 μg per kg b. wt), ND3 (100 μg per kg b. wt) and free curcumin (FD) (100 μg per kg b. wt). Control (N) group shows no expression for the NF-κB marker whereas the ischemic (I) group shows maximum expression. Treatments ND1 and ND2 show moderate expression but less than free curcumin, ND3 shows minimum expression.
