Fig. 8From: Putative anti-inflammatory, antioxidant, and anti-apoptotic roles of the natural tissue guardian methyl palmitate against isoproterenol-induced myocardial injury in ratsImmunohistochemical analysis of NF-kB and COX-2 in heart sections (magnification × 400). a and e Control group showing normal architecture with minimal expression of NF-kB and COX-2 respectively. b and f MP group showing minimal expression of NF-kB and COX-2 respectively. c and g ISO-intoxicated group showing extensive heavy expression of NF-kB and COX-2 respectively. d and h MP-pretreated group showing mild expression of NF-kB and COX-2 respectively. i and j Quantitative image analysis for immunohistochemical staining of NF-kB and COX-2 respectively expressed as optical densities (OD) across 10 different fields for each rat section. Data are presented as mean ± SD (n = 10); a or b: significantly different from control or ISO groups respectively at P < 0.05 using one-way ANOVA followed by Tukey as post hoc test.
