Evaluation of lymphocyte apoptosis in dogs with inflammatory bowel disease.

Objective: To determine whether lymphocyte apoptosis in intestinal mucosae is more common in healthy dogs than dogs with inflammatory bowel disease (IBD) and whether numbers of apoptotic cells increase after successful treatment of affected dogs.

Animals: 8 dogs with IBD (IBD dogs) and 8 healthy control dogs.

Procedures: Biopsy specimens of the duodenum and colon were obtained via endoscopy from dogs with IBD before and after 10 weeks of standard treatment and compared with specimens obtained from control dogs.
