71.   The median and minimum of five local blood flow measurements performed in each patient were inversely correlated with the endoscopic recurrence grade.

72.   Interpretation of blood flow recordings and endoscopic grading were performed in a mutually blind fashion.

73.   The reproducibility of blood flow measurements performed in this way was assessed in separate patients by performing successive recordings at a single location.

74.   All cultures were performed in triplicate.

75.   The tests were performed in LAB-TEK slides as described earlier.

76.   This study was performed in an attempt to estimate the mucosal activity of neutrophils in ulcerative colitis and elucidate the possible neutrophil activating role certain cytokines may exert.

77.   The measurements were performed in the perfusion fluid obtained during regional perfusion of inflamed sigmoid and rectal segments.

78.   All procedures were performed in fasted patients.

79.   Upper gastrointestinal endoscopy was normal in all patients, and a manometric test was performed in all of them.

80.   As we did not perform endoscopy in this control group, we cannot rule out the inclusion of a few patients with gastritis.
