Immunohistochemical staining of α-SMA, ×100. a Control untreated kidney showing normal expression of SMA within the wall of interstitial arterioles. b Cisplatin treated rat showing a moderate reaction in the interstitial tissue. c Honey treated rats expressing no reactivity. d RJ treated rats expressing minimal reaction. e Data represent the expression level of α-SMA in cisplatin, honey, and RJ groups: *significant difference from normal control group at P < 0.05, **significant difference from cisplatin group at P < 0.05
