Density of CD45 + cells in the ileal and colonic mucosa following intratracheal LPS administration. CD45 + cells were significantly increased in the ileum at both 24 and 72 h following LPS administration (A). LPS had no effect on CD45 + cell expression in the colon (B). Representative photomicrographs of CD45 staining before and after thresholding in the ileum at 24 h following vehicle control (C,C`) and LPS (D, D`) administration. Scale bar = 50 µm. Data were analysed by unpaired t-test with Welch's correction. Data presented as mean ± SEM. *P < 0.05 significantly different to vehicle control, n = 3–7 for ileum data, n = 5 for colon data
