Serum levels of the pro-inflammatory mediator nitric oxide. Serum levels are expressed relative to those of the normal control group. Bars Mean ± standard deviation (SD), n = 8. Significant differences between groups are analyzed by one-way analysis of variance (ANOVA). *P < 0.001 compared to normal control group, § P < 0.001 compared to cancer control group, ns non-significant (P > 0.05) compared to normal control group. NSEE Nigella sativa ethanolic extract, DENA diethylnitrosamine. See Materials and methods subsection Experimental design for a detailed description of the animal groups
