Se deficiency induces arteritis in broilers. (A) Se content in plasma of broilers (N = 10; ***P < 0.001). (B) Histopathological changes of aortas of broilers (scale bar, 200 μm). Fields from one representative experiment of three are shown. (C) IF analyses of TNF-α (red) and IL-1β (green) in broiler aortas (scale bar, 20 μm). Fields from one representative experiment of three are shown. (D) Quantification of relative TNF-α and IL-1β intensity in broiler aortas (N = 3; Bars that do not share the same letters are significantly different (P < 0.05) from each other). Results are presented as mean ± SEM. Statistical significance was obtained by one-way ANOVA or unpaired Student's t-test.
