Interferon-gamma (IF-γ), interleukin-12 (IL-12), tumor necrosis factor-alpha (TNF-α), and total antioxidant capacity (TAC) levels and catalase activity of the groups fed Nigella sativa seeds (30 g/kg and 50 g/kg) and the control group.

Treatment	Cytokine parameters			Antioxidant parameters
	IF-γ (pg/mL)	IL-12 (pg/mL)	TNF-α (pg/mL)	TAC (mmol/l)	CAT (mmol/l)
Control	461.8 ± 3.9c	12.89 ± 0.1c	6.83 ± 0.03c	0.864 ± 0.003c	3.85 ± 0.01c
Sa30	566.5 ± 6.2b	15.72 ± 0.1b	8.804 ± 0.1b	1.070 ± 0.03b	4.27 ± 0.03b
Sa50	627.5 ± 1.9a	20.89 ± 0.1a	11.17 ± 0.1a	1.31 ± 0.02a	4.87 ± 0.01a

The data are presented as the means ± SEs, n = 6 per group. Means within the same column with different superscript letters are significantly (P < 0.05) different according to one-way ANOVA followed by Duncan’s post hoc analysis. Sa30: group fed Nigella sativa at 30 g/kg diet; Sa50: group fed Nigella sativa at 30 g/kg diet.
