Open Access Abstract Introduction Mierovaseular dysfunction causing intravascular leakage of fluid and protein contributes to hypotension and shock in sepsis. We tested the hypothesis that abrogation of inducible nitric oxide synthase iNOS activation would decrease leukocyte rolling leukocyte adhesion and microvascular leakage in sepsis. We compared wild-type mice made septic by cecal ligation and puncture with mice deficient in iNOS. Methods Leukocyte dynamics and microvascular permeability were assessed simultaneously by fluorescence intravital microscopy in the cremaster muscle 15 to 20 hours after induction of sepsis by cecal ligation and puncture in C57Bl 6 mice. Rolling and adhesion of leukocytes labeled with rhodamine and leakage of fluorescein isothiocyanate-conjugated albumin was measured in single nonbranching venules 25 to 40 pm and compared among septic wild-type septic iNOS-deficient transgenic and sham-operated control mice. Results Leukocyte rolling and adhesion were increased in septic animals cells minute and .
