Beta-endorphin and cold pressor test in the aged

In 8 young and 8 elderly subjects mean values of plasma beta-endorphin were nearly equal under basal conditions. In all subjects the cold pressor test provoked a marked increase of beta-endorphin, which was more evident in young subjects. Mean values of the areas of endorphin modifications were the...

Description
Summary:In 8 young and 8 elderly subjects mean values of plasma beta-endorphin were nearly equal under basal conditions. In all subjects the cold pressor test provoked a marked increase of beta-endorphin, which was more evident in young subjects. Mean values of the areas of endorphin modifications were the same in both young and elderly subjects. These results may suggest that after a short-term stimulus, such as the cold pressor test, no marked differences in pituitary secretion between young and elderly subjects may be evidenced.
