Sequential evaluation of leukocyte-endothelial interactions. The number of rolling leukocytes is expressed as percentage of the number of passing leukocytes. The number of adherent leukocytes is expressed as the number of adherent cells per field. Sequential measurements were performed at baseline and after one (t = 1 h), two (t = 2 h), and three (t = 3 h) hours of LPS injection. LPS, endotoxemic animals (n = 10); LPS/FR, endotoxemic and fluid resuscitated animals (n = 10); LPS/FR/LNNA, endotoxemic, fluid resuscitated, and L-NNA + L-Arginine treated animals (n = 10). ^† p <0.05 vs. group baseline; *p <0.05 vs. LPS group at the same time point; ^§ p <0.05 vs. LPS/FR group at the same time point.
