11.   Ten gastric mucosal biopsy specimens were required for DNA extraction.

12.   This was small in comparison with the radioactivity produced by substrate metabolism in the presence of mucosal biopsy specimens.

13.   We have used a technique, whereby mucusal metabolism can be measured in mucosal biopsy specimens, and therefore patients in remission can easily be studied.

14.   A colonic mucosal biopsy obtained at endoscopic follow up from a non-inflammatory bowel disease patient with a colonic polyp was also positive for M paratuberculosis.

15.   The two non-inflammatory bowel disease cultures were from mucosal biopsies, one grew spheroplasts and the other acid fast bacilli.

16.   Upper gastrointestinal endoscopy and colonoscopy were macroscopically normal and mucosal biopsy specimens were obtained.
