Pancreatic fistula duodenal endocrine cell secretion

Abstract

Since the time of Ivan Petrovich Pavlov's work, it is known that the juice collected from the pancreatic fistula, when it is re-introduced into the duodenum, inhibits the secretion of the pancreas. Most recently, in the works of American, French and Japanese physiologists, this inhibition was associated with the fact that trypsinogen secreted in the pancreatic secretion and trypsin contained in the duodenal contents inhibit the release of the hormone cholicystokininpancreosimin by duodenal endocrine cells - a powerful stimulator of enzyme secretion by the pancreas. This explanation of the reverse reproduction of pancreatic secretion from the duodenum is recognized by most experts. In connection with the above, the study of this problem seems to be an urgent task.

ABSTRACT

Since the time of Ivan Petrovich Pavlov's work, it is known that the juice collected from the pancreatic fistula, when it

is re-introduced into the duodenum, inhibits the secretion of the pancreas. Most recently, in the works of American,

French and Japanese physiologists, this inhibition was associated with the fact that trypsinogen secreted in the

pancreatic secretion and trypsin contained in the duodenal contents inhibit the release of the hormone

cholicystokininpancreosimin by duodenal endocrine cells - a powerful stimulator of enzyme secretion by the pancreas.

This explanation of the reverse reproduction of pancreatic secretion from the duodenum is recognized by most

experts. In connection with the above, the study of this problem seems to be an urgent task.

INTRODUCTION

Acute experiments were performed on 10 dogs in 2

series under hexanal anesthesia on controlled

breathing. The collection of pancreatic juice was

carried out from the main pancreatic duct of the

pancreas, the additional duct was ligated. The

duodenum was separated from the stomach by a

ligature applied at the site of the pyloric sphincter. In

one series of experiments, a catheter was

strengthened in the initial part of the duodenum, and

in another series, another catheter was strengthened

in the ileum. Pancreatic secretion was stimulated by

intraduodenally administered hydrolysin acidified to

pH 2.0 (0.6 ml/kg every 15 min). A cannula was inserted

into the femoral veins to take blood, a cannula to take

blood, and ureters were cannulated to collect urine.

After a two-hour collection of juice, urine and blood (in

hourly portions), an amylase solution (0.15 mg / kg /

hour) was injected into the duodenum, in the next two

hours the collection of juice, urine, blood

(consequence) was continued, then the cycle was

repeated again. The second series of experiments was

carried out according to the same scheme, but amylase

was injected not into the duodenum, but into the

ileum. In the juice collected and accounted for by the

volume

of

hourly

periods,

bicorbanates

(titrometrically), amylase (according to Smith-Roy in

the modification of Ugolev), lipase (according to Titz),

total proteolytic activity (according to Kunitz), protein

(according to Lowry) were determined. Amylase was

determined in urine and blood by the same method as

in juice. The results obtained in the first B series of

experiments

showed

that

intraduadenal

administration of amylase causes a significant

inhibition of pancreatic secretion of amylase, the

secretion of other enzymes and bicarbonates did not

undergo changes. When amylase was injected into the

ileum at the hour of its administration, no inhibition of

pancreatic secretion was observed. Nonselectively

generalized inhibition of pancreatic secretion

developed after 1-2 hours, it was at this time that

hyperamylasuria was also noted. The results obtained

indicate the leading role of duodenal mechanisms in

the urgent selective, feedback-based inhibition of

pancreatic enzyme secretion. A more delayed non-

selective inhibition of pancreatic secretion may be due

to the action of enzymes absorbed from the distal

parts of the small intestine from the bloodstream.

Indirect evidence of the participation of duodenal

peptides in the implementation of inhibitory selective

effects of enzymes (amylase) from the duodenum on

the secretion of pancreatic hydrolases was also that

the

secretion

stimulated

by

inraduadenal

administration of hydrolysin (that is, endogenous

duodenins) is inhibited more pronounced than the

secretion stimulated by exogenous secretin with

cholicystokinin. The search for specific mechanisms

through which inhibition of pancreatic secretion by

intraduodenally injected amylase is realized continues.

But the experimental data already obtained indicates

that the adaptation of enzyme secretion by the

pancreas depends more on the enzymatic activity of

the duodenal contents.
