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

Figure 5

The cortical renal tubules exhibit a strong widely distributed eNOS cytoplasmic reaction in both the control (a) and TQ (b) groups. The hypothyroid group shows a weaker and more localized reaction (c). Hypothyroid rats administered TQ display more evident reaction in the renal tubules (d) (eNOS, ×400, ). eNOS expression in the renal glomeruli (e) of the studied groups is represented.
