Resumen
Introducción

Dada la controversia aún existente, se ha desarrollado un modelo experimental para determinar en el páncreas el papel de la insulina y el glucagón sobre su función exocrina, y el papel de la colecistocinina y la secretina sobre su función endocrina.

Material y métodos

El modelo se ha aplicado a un total de 60 ratas anestesiadas y estimuladas con dosis fisiológicas y suprafisiológicas de dichas hormonas administradas mediante perfusión continua. Se han medido en el jugo pancreático el volumen y las actividades y producciones enzimáticas de amilasa, lipasa y tripsina a los 0, 20, 40 y 60 min del inicio de las perfusiones. En el plasma se han determinado los valores de insulina, glucagón y glucosa a los 0, 10, 30 y 60 min.

Resultados

A dosis tanto fisiológicas como suprafisiológicas, la insulina y el glucagón modifican la secreción pancreática exocrina, y la colecistocinina altera la secreción pancreática endocrina. La secretina incrementa la secreción endocrina sólo a dosis suprafisiológicas.

Conclusiones

En condiciones basales in vivo y con dosis de estimulación hormonal de rango fisiológico, existe una interacción hormonal endoexocrina en la glándula pancreática.

Introduction

In view of the continuing controversy regarding the interaction between the endocrine and the exocrine pancreas, we developed an experimental model to determine the role of insulin and glucagon on exocrine function, as well as to determine the role of cholecystokinin and secretin on endocrine function.

Material and methods

We applied the model to 60 anesthetized rats, stimulated with continuous infusion of physiological and supraphysiological doses of the above-mentioned hormones. The volume and activity of amylase, lipase and trypsin in pancreatic juice were measured at 0, 20, 40 and 60 minutes after starting the infusion. Plasma levels of insulin, glucagon and glucose levels were measured at 0, 10, 30 and 60 minutes.

Results

Insulin and glucagon modify exocrine secretion of the pancreas at physiological and supraphysiological doses. Cholecystokinin alters endocrine secretion of the pancreas at both physiological and supraphysiological doses, whereas secretin increases endocrine secretion only at supraphysiological doses.

Conclusion

Hormonal interaction between the endocrine and the exocrine pancreas was found in vivo under basal conditions with hormonal stimulation using physiological doses.
