Quantitative analysis of terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labelling (TUNEL)-positive cells in rat livers. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labelling-positive apoptotic cells were counted in 15 random fields, and the data were expressed as the mean number of TUNEL-positive cells/field. All results were given as mean ± SEM of n = 6 animals. Bars that do not share same letters (superscripts) are significantly different from each other (P < 0.05). Experimental groups for 5 week were on the following: (c) regular diet (0.15 mg/kg Se); (SeS) Se-supplemented diet (1 mg/kg Se); (SeD) Se-deficient diet (≤0.05 mg/kg Se); (DEHP) regular diet (0.15 mg/kg Se) and received 1000 mg/kg, i.g. DEHP for the last 10 days; (DEHP/SeS) Se-supplemented diet (1 mg/kg Se) and received 1000 mg/kg, i.g. DEHP for the last 10 days; (DEHP/SeD) Se-deficient diet (≤0.05 mg/kg Se) and received 1000 mg/kg, i.g. DEHP for the last 10 days.
