Human exocrine pancreatic secretion changes associated with age.

A retrospective study of data from 2352 secretin tests has been studied. Age-related changes in the structure and function of the gastrointestinal tract have been the subject of many publications. There is a consensus that basal and stimulated gastric secretion declines with age. Studies of pancreatic secretion in the elderly are scattered in the old literature and are rather controversial. Previously published data from this laboratory indicated that age and sex have little or no influence upon the secretory responses of the human pancreas to a standard dose of secretin. Almost 20 years have passed since this publication. The present report is a retrospective analysis of the observations gathered over this period.

[Conditioning of stress induced blood glucose and blood lipid changes].

The evidence for acute metabolic changes following intensive stress arises from a number of experimental studies. In our investigations we could differentiate these results, as we demonstrated that there exist pronounced differences in the metabolic changes after single, multiple and repeated stress and that furthermore neutral signal stimuli--after a series of simultaneous presentations with the stressor stimul (= conditioning phase) may induce conditioned changes in blood glucose and some blood lipid fractions. According to our hypothesis these learned ("conditioned") stress reactions may play an important role in the development and maintainance of various psychosomatic disturbancies.
