Abstract
1) Utilizing the complete-anemia method devised by HUKUHARA et al., the intramural ganglion cells of the dog ileocecocolic region were destroyed.
2) The animal could not be fed because it vomited every time it took food. The animal survived29days by i. v. infusion of the nutrient solution.
3) The roentgenological examination revealed that the segment affected was in a state of persistent constriction. The histological examination revealed that intramural ganglion cells disappeared in the middle portion of the constricted segment, and that they showed signs of degeneration in the region 0.5-1.0cm close to both ends of the segment.
