Article Synopsis
  • A modified method using chondroitin sulfate A as a standard was used to quantify mucin from isolated colonic fistulas in 8 dogs.
  • In 25 experiments, the effect of secretin on mucin secretion was tested, revealing that secretin increased colonic mucin levels.
  • This research model is effective for studying potential drugs aimed at enhancing colonic mucin secretion in cases of impaired colonic motility.

Photopenic abnormalities induced by radiation therapy are important to recognize on bone scans, since they often affect longitudinal or lateral symmetry. This phenomenon was studied in 43 patients treated through 67 ports (including the axial skeleton). Bone doses spanned 450-6,700 R (mean +/- S.

In 8 dogs a colonic pouch with fistula was surgically created. Mucin secretion was measured by washing mucus out of the pouch and then, after a number of chemical steps, by determining the turbidity with spectrophotometry. The movement of tantalum particles insufflated into the canine rectum during periods of absence of contractions was correlated with mucus secretion in the pouch.
