FIGURE 15.

Toluidine blue‐stained cerebral cortex sections from rats treated with (a) normal saline (control); show the array of well‐organized and normal morphology of neuronal cells, granular cells (GC), and pyramidal cells (PMC). (b) 100 mg/kg of curcumin (cur 100) showing cellular degenerations: (c) cur‐CSCaCO₃NP 50 and (d) cur‐CSCaCO₃NP 100 showing fewer damaged neuronal cells with marked improved normal neuronal cells (green arrow). (e) Quantitative representation of degenerated neuronal cells of the control and all the treated groups. *p < 0.05 versus control, n = 5. (Toluidine blue, ×10, scale bar = 200 μm)
