A 9-year-old, mixed-breed, castrated male dog presented with a one-week history of severe vomiting. Abdominal radiography showed a dilated small intestine loop. Abdominal ultrasonography showed small-intestine distension up to 5 cm in diameter without mechanical obstruction. During exploratory laparotomy, an aperistaltic ileal segment was resected. There was no narrowed cavity in the resected plane. Histopathologic and immunohistochemical findings confirmed visceral myopathy due to intestinal adenocarcinoma in the ileum and revealed partial destruction of the longitudinal and circular muscles with fibrosis. Chronic intestinal pseudo-obstruction caused by adenocarcinoma was diagnosed after considering the above investigative results.

Hirschsprung's disease (HD) is usually diagnosed in the newborn period and early infancy. The common presentation of HD in newborns consists of a history of delayed passage of meconium within the first 48 hours of life. The differential diagnosis in newborns is one of the clinical challenges of this disorder. A number of medical conditions which cause functional obstruction of the intestines are easily excluded. Neonates with meconium ileus, meconium plug syndrome, distal ileal atresia and low imperforate anus often present in a manner similar to those with HD in the first few days of life. Abdominal radiographs may help to diagnose complete obstruction such as intestinal atresia. Microcolon on contrast enema can be shown in cases with total colonic aganglionosis, ileal atresia or meconium ileus. Suction rectal biopsy or frozen section biopsy at operation is essential for differential diagnosis in such cases. HD is also considered in any child who has a history of constipation regardless of age. Older children with functional constipation may have symptoms that resemble those of HD and contrast enema is usually diagnostic. However, children with other motility disorders generally referred to as chronic idiopathic intestinal pseudoobstruction present with very similar symptoms and radiographic findings. These disorders are classified according to their histologic characteristics.; visceral myopathy, visceral neuropathy, intestinal neuronal dysplasia (IND), hypoganglionosis, immature ganglia, internal sphincter achalasia. Therefore, the workup for motility disorders should include rectal biopsy not only to confirm the presence of ganglion cells but also evaluate the other pathologic conditions.

Nutritional ceroidosis accompanied with histopathological changes such as myopathy and visceral ceroidosis, was experimentally induced by feeding the oxidized feed with the peroxide value of 98meq/kg, to common carp resulting in some motalities of carp. To see the effect of treacetment survivors of the above fish were orally administered by feeding diets containing daily doses of 3mg and 6mg of glutathione per kg fish for 10 days or 20 days. While control and 3mg dosage group retained viscerral ceroidosis and showed evidence myopathy histo pathologically, the fish treated with 6mg of glutathione for 20days showed obvious reduction of macrophages of ceroid in the viscera.

Tilapia, Oreochromis niloticus, weighing 100g on average was fed on the oxidized pellet diets in peroxide value (POV) 102 meq/kg, with or without the vitamin mixture of C and E for 67 days. After administration of vitamin mixture for 67 days, the fish fed them displayed better growth than the fish fed oxidized pellet only. The fish fed low level of the vitamin mixture or the oxidized pellet retained visceral ceroidosis but did not show myopathy. But the fish administered high level of the vitamin mixture lossed macrophages disposing of ceroid in the viscera. Based on the results, the administration of vitamin mixture at high level was effective as prophylaxis for ceroidosis.
