The activity of digestive enzymes in the digestive and nondigestive organs during stress exposures

The effects of fasting and immobilization manifests itself in changes of the enzymes activity in the stomach, duodenum, jejunum, ileum, colon as well as in the liver, spleen, kidneys. In these conditions, the protective function is primarily fulfilled by the enzyme systems of the non-digestive organs whereas the enzymatic intestinal barrier is less obvious.
