Table 3 Catalytic NOS activity in the white matter regions (dorsal columns, lateral columns and ventral columns) of the lumbosacral spinal cord segments (L4–S4) in control, after partial ischemia (13, 15 and 17 min) and 24 h after ischemic insult

  1. The results from analyses were expressed as pmol/mg protein. The values were statistically evaluated by ANOVA and Tukey-Kramer test and have been given as means ± SEM. Data are the means of seven experiments (n = 7)
  2. P < 0.05 compared with control; ** P < 0.05 compared with ischemia alone
  3. IS ischemia, R reperfusion
