[Digestive enzyme activity in growing rats consuming nitrates against a background og protein insufficiency]. / Aktivnost' pishchevaritel'nykh fermentov u rastushchikh krys pri potreblenii imi nitratov na fone belkovoi nedostatochnosti.

The effects of sodium nitrate on the activity of digestive enzymes in mucosal and submucosal layers of the small intestine as well as in liver and kidney were studied in the growing rats maintained on either standard or protein-free diets. The enzyme systems were more sensitive in the growing rats to protein deprivation than in adult animals. However, the digestive enzymes were more resistant against nitrate intoxication in the growing rats.
