Gene expression of the inflammatory markers (A) ICAM and (B) VCAM in the renal cortex 72 h after intraperitoneal injection of 0, 2, 5, 7.5 and 10 mg/kg F or 0, 2, 4 and 5 mg/kg UN in mice. The mRNA results are expressed as a ratio to the mRNA levels of the housekeeping genes glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and hypoxanthine-guanine phosphoribosyltransferase (HPRT). The results are presented as the mean ± standard error of the mean. The asterisk represents a significant difference between the treated (n = 6) and control (n = 5) groups (Holm-Sidak test, * p < 0.05, ** p < 0.005, *** p < 0.001).
