PEPTIC ULCER 1

SECRETIN

This hormone is released from the proximal duodenal mucosa into

the blood stream.

- The hormones causes a secretion from the pancreas of bicarbonate,

a similar increase of bicarbonate is also caused in the bile.

- Pepsinogen secretion of gastric mucosa is increased.

- Gastrin and acid secretion from stomach is decreased.

Secretin

Secretin is the hormone that is the main stimulant of bicarbonate and water secretion from the centroacinar cells lining the proximal pancreatic ducts.

Secretin is produced by the S cell in the duodenum and jejunum. This action is stimulated of the release of secretion when the luminal pH of 4.5 or less. Circulating secretin stimulates bicarbonate-rich fluid from the centroacinar cells of the pancreas and from Brunner’s glands in the duodenum.

PEPTIC ULCER

A peptic ulcer is an erosion (break down) of the mucosa of the

gastrointestinal tract located adjacent to acid-secreting cells

and it occurs in the;

*  Lower oesophagus (Barrett's Ulcer)

*  The antrum of the stomach(Gastric ulcer)

*  Duodenum first part(Duodenal ulcer)

*  The jejunum at the margin of a gastrojejunostomy

*  In the ileum at the outlet of a Meckel's diverticulum  bearing

   aberrant gastric mucosa

Duodenal and Gastric ulcer are types of ulcers most often

seen in practice.
