BAI-LZM inhibits inflammation via the nuclear factor-κB pathway in rats with DN. The protein levels of p65 were detected by (A) immunofluorescence and (B) immunohistochemistry (magnification, × 400). (C) The levels of phosphorylated-p65, p65, IL-1β and IL-6 protein were detected by western blotting. Con, saline; DN, 65 mg/kg STZ; DN/B, 65 mg/kg STZ + 160 mg/kg/day BAI; DN/B + L, 65 mg/kg STZ + 160 mg/kg/day BAI-LZM. The results are representative of 3 independent experiments. Data are presented as the mean ± standard deviation ^*P < 0.05, ^**P < 0.01 between the values in DN, DN/B and DN/B + L rats vs. the baseline levels (Con), as calculated by Student’s t test. ^#P < 0.05, ^##P < 0.01 between the DN and BAI/BAI-LZM treatment groups, as calculated by one-way analysis of variance. ^$P < 0.05, ^$$P < 0.01 between the BAI and BAI-LZM treatment groups, as calculated by one-way analysis of variance. P-values were calibrated using the Bonferroni correction. BAI-LZM, baicalin-lysozyme; DN, diabetic nephropathy; STZ, streptozotocin; Con, control; IL, interleukin
