  3. 1Average number of nerve profiles per area studied (mean ± SEM)
  4. 2Relative frequency of particular neuronal subclasses is presented as % (mean ± SEM) of all neurons counted within the ganglia stained for PGP 9.5
  5. 3The density of intraganglionic nerve fibers positive for leuENK is presented in arbitrary units
  6. Statistically significant data (p ≤ 0.05) between C group and group C1, I and A in the number of leuENK-LI nervous structures within particular part of the colon are marked by different letters and not significant data are marked by the same letters
