Serum inducible nitric oxide synthase (iNOS) enzymatic activity. Enzymatic activities of the different groups are expressed relative to that of the normal control group. Bars Mean ± SD, n = 8. Significant differences between groups are analyzed by one-way ANOVA test. *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
