Photomicrographs of immunohistochemistry of cytochrome C in kidney sections of the control group (a). Acrylamide-administrated groups showed the decrease in expression at 30, 45, and 60 days (b–d). Chips feeding groups at 30, 45, and 60 days (e–g) showed slight downregulated expression compared to the control. BV-treated group (h) and BPF-treated group (i) at 60 days showed downregulated expression of cytochrome C as compared to the control. Acrylamide-administrated groups treated with either BV (j) or BPF (k) showing improvement of downregulated expression of cytochrome C compared to acrylamide administration. Chips feeding groups treated with either BV (l) or BPF (m) showing the normal expression and distribution of staining that was mostly similar to the control.
