Fig. 5. Quantification of cFos expression in spinal cord across T12 to L2 levels. An average of cFos expressing cells in randomly selected sections from each level here and the expression from T12 to L2 were summed. Animals receiving intrathecal ketorolac, 25 (n = 5) or 50 μg (n = 6), had similar cFos expression compared with uterine cervical lidocaine infiltration and sham surgery, whereas those receiving uterine cervical distension with intrathecal saline had a four- to fivefold increase in cFos compared with control groups. *P < 0.05 compared with sham surgery, cervical lidocaine injection, and intrathecal ketorolac, 50 μg.
