“…He quotes Miura as having first seen this hypertrophy in 1913, and it has also been confirmed by others (Ambrosi, 1942;Benninghoff, 1951). The ganglion cells in Meissner's plexus show a greater hypertrophy than those in Auerbach's plexus, but this may only be because they are normally more easily visible (Sauer and Rumble, 1946).…”

SUMMARY Teflon mesh was wrapped around the terminal ileum of dogs to cause a partial obstruction. Both smooth muscle layers became thickened in the gut proximal to the constriction, but the circular muscle was more hypertrophied than the longitudinal. The cells in Auerbach's plexus were stained by an indoxyl esterate technique in lOO,u sections and counted. The number of ganglion cells related to muscle mass was decreased above the constriction. Although some ganglion cells increased in size there was no evidence of any increase in number.

SummaryIn six healthy mongrel dogs, hypertrophy of the ileum was induced by experimental stenosis. The number, size and morphological appearance of myenteric ganglion cells in the hypertrophic ileal segments were compared with those in corresponding segments of twelve normal control animals. The following observations are reported. 1. The number of ganglion cells is expressed as N/G, i. e. the mean number of neuronal perikarya identifiable in each myenteric ganglion appearing in a complete, 8 ~t thick transverse section of the ileum. 2. The mean value of N/G in five control animals was found to be 8.94 + 0.064, while in hypertrophied intestines a value of 5.17 -+ 0.062 was obtained, a difference significant at the P < 0.01 leve] of confidence. 8. The mean diameter of neuronal nuclei in six hypertrophied intestines measured 10.07 + 0.154 micra, a value significantly higher than the 8.05 -+ 0.102 micra mean established in twelve controls. Compared with normal material, the distribution curve of nuclear diameters measured in hypertrophic intestines' shows a flattening and a shift to the right. 4. In comparison with normal ganglion cells, most ganglion cells in hypertrophic ilea showed a prominent increase in Nissl substance, 5. In sections impregnated by Jabonero's silver method, evidence was found of an increase in cell-size and in argyrophilia of both argyrophilic and argyrophobic cells in hypertrophied intestines. This phenomenon is particularly pronounced in the larger argentaffine cell groups. The present findings may represent morphological corollaries of changes in the activity level of neurons associated with increased functional demands.
