The activities of microvillus aminopeptidase (microsomal, EC 3.4.11.2), dipeptidyl peptidase IV (EC 3.4.14.-), glycyl-leucine dipeptidase (EC 3.4.13.11), proline dipeptidase (EC 3.4.13.9), sucrase (EC 3.2.1.48) and gamma-glutamyl transpeptidase (EC 2.3.2.2) were measured in peroral intestinal biopsies taken from patients with coeliac disease in the acute phase and in remission. A comparison with the amounts of corresponding activities from a reference group showed that all the measured activities were significantly decreased in the acute phase of the disease. In patients in remission only microvillus aminopeptidase and dipeptidyl dipeptidase IV displayed a substantial depression as compared to the reference group. It is suggested that a primary mucosal digestion defect will result in lack of substrate for other intestinal enzymes. This is a situation comparable to starvation and may explain the variation in the grade of restitution for the different enzymes.

In the crewmembers of four Salyut-6 long-term flights, enzyme excretory function of the gastro-intestinal tract was investigated. These studies included: gastric proenzyme, pepsinogen, and pancreatic enzymes, amylase and lipase, in blood and urine, trypsin in blood, intestinal enzymes, invertase and glycyl-L-leucine dipeptidase in feces, and lipids in feces. The results obtained demonstrated a correlation between changes in enzyme excretion and space flight duration and profile. After the 140- and 175-day flight the most marked changes in the digestive organs were seen; they manifested as a simultaneous increase in secretory function of the stomach and the pancreas. However, after the 185-day flight, in which advanced countermeasures were used, the above changes were less distinct.

The activities of amylase, total proteases, monoglyceride lipase, glycyl-leucine dipeptidase and sucrase were investigated in mucosa from five consecutive parts of small intestine in blue fox, mink, ferret and rat. In comparison with rats, the activity gradient of carbohydrates and TPA in mucosa of predatory animals was shifted in the distal direction. The distribution of dipeptidase and monoglyceride lipase along the intestine was similar enough in all animals: the first was exemplarily the same all along the gut, while the second slightly decreased in a distal direction.

Studies have been made on the formation of the spectrum of digestive enzymes in the small intestine of weanling rats which were taken from lactating female and given semisynthetic food at the age of 17, 21 and 25 days. It was shown that the rate of general development and maturation of the digestive enzymes depends on the age of animals and the mode of their breeding (isolated or in a group of the same age). These factors significantly affect also the level of the activity and proximo-distal gradient of distribution of the following intestinal enzymes: lactase, sucrase, alkaline phosphatase, alanine aminopeptidase, glycyl-L-leucine dipeptidase, as well as the mass of the mucose and protein content of the small intestine.

Low protein content in the ration of rat pups during transfer from mixed to definitive nutrition (days 21-30 of life) has a negative impact on digestive function of the small intestine and trophic and barrier functions of the large intestine, liver, and kidneys and increases (sucrase, glycyl-L-leucin dipeptidase) or decreases (alkaline phosphatase, aminopeptidase M, glycyl-L-leucine dipeptidase) enzyme activities in these organs in 6-month-old rats. Protein deficiency during the early ontogeny modulates functioning of the enzyme systems in digestive and non-digestive organs in adult life, which can lead to the development of not only gastrointestinal, but other visceral diseases.
