title: Functional magnetic stimulation facilitates colonic transit in rats.
abstract: OBJECTIVE
  To investigate the effect of functional magnetic stimulation (FMS) on colonic transit in rats.
  
  
  METHODS
  Experimental.
  
  
  METHODS
  Functional magnetic stimulation laboratory in a Veterans Administration health care system.
  
  
  METHODS
  Twenty-four female Wistar rats, divided into an experimental group and a control group.
  
  
  METHODS
  All rats had technetium 99m (Tc 99m) infused through a cecal catheter to assess colonic transit times. FMS was performed over the cervical region; a figure of 8 magnetic coil was used in the experimental group. The colon was removed and sectioned into 10 segments, and a stool sample was taken in both groups.
  
  
  METHODS
  Distribution of radioactivity within the large intestine and stool were measured.
  
  
  RESULTS
  Geometric center calculations showed significant differences (p <.001) between the control group and the experimental group when the distribution of radioactivity along the colon was measured. The percentage of Tc 99m recovered from the stool in the experimental group was significantly higher than the percentage recovered from the control group.
  
  
  CONCLUSIONS
  FMS facilitates colonic transit in a rat model.
