Sensory thresholds to electrical stimulation (ES) of the rectum
First stage (saline) | Second stage (αhCRH 9–41) | p Value | |
---|---|---|---|
Data are expressed as mean (SEM) (mA). There was no significant change between the two stages of the experiment by the paired t test. However, all thresholds in the antagonist stage (second stage) showed higher mean values than those in the saline stage (first stage). | |||
