Both insulin and glucagon affect the basal exocrine pancreatic secretion in vivo when physiological doses are administered.

In order to study the effect of cholecystokinin and secretin on the endocrine function of the pancreas, we have developed an experimental model that we have applied to a total of 30 anesthetized rats stimulated with physiological or supraphysiological doses of cholecystokinin and secretin administered intravenously by continuous infusion. Our results show that the serum insulin concentration increases after the supramaximum dose of cholecystokinin is infused, while that of glucagon increases after the maximum dose of this hormone. In case of secretin, the serum glucagon level increases after the supramaximum dose, while that of insulin is not affected by any dose. We conclude that after infusion of physiological doses of cholecystokinin, the pancreatic secretion of glucagon is modified but not that of insulin, while secretin has no effect on the endocrine pancreatic secretion of either insulin or glucagon upon the same conditions.

The right to one's own image is a relatively young right that, in Spain, has its roots in the dignity of the person and it was first recognized in the 1978 Constitution. It is a right that arises from the self-determination of the human being and that is related with other rights such as the right to honor, privacy, protection of personal data, even with older ones such as the right to the inviolability of the home and the right to secrecy of communications. This characteristic makes it different from a purely commercial right, although it can't be denied that, possibly, this is the constitutional right with the greatest economic content.
