Fig. 5. Photomicrographs showing testis tissues of control and treatment groups. (A) is from the control group. (B) is from the 100 mg kg^–1 per day DEHP treatment group and it shows congestion (black arrow) and pycnotic nucleus (asterisk). (C) is from the 200 mg kg^–1 per day DEHP treatment group and it shows congestion (black arrow) and cells in the lumen (asterisk). (D) is from the 400 mg kg^–1 per day DEHP and it shows pycnotic nucleus (asterisk) and congestion (black arrow) (all were stained with contrast by H&E, ×200). In TUNEL staining, (A) is from the control group. (B) is the 100 mg kg^–1 per day of DEHP, (C) is the 200 mg kg^–1 per day of DEHP and (D) is the 400 mg kg^–1 per day of DEHP. Black arrows show apoptotic cells in testes (×400).
