Thymoquinone Upregulates Catalase Gene Expression and Preserves the Structure of the Renal Cortex of Propylthiouracil-Induced Hypothyroid Rats

Figure 4

The renal cortex of the control (a), TQ (b), hypothyroid (c, d), and hypothyroid+TQ (e) groups. Little collagenous fibers are seen surrounding the renal corpuscle (thin arrow) and in the interstitium between the tubules (empty arrows) in the control and TQ groups. In the hypothyroid group, deposition of more collagenous fibers is marked around the renal corpuscle and in between the tubules. Less deposited fibers are noticed in the hypothyroid+TQ group (Masson’s trichrome stain ×400, scale ). The area percent of Masson-stained collagen fibers (f) of the studied groups is represented.
