[Effect of synthetic analogs of L-enkephalin on viable areas of the pancreas in experimental pancreatitis].

Synthetic analogues of L-enkephalin--tageflar and dalargin were studied for the treatment of experimentally-induced pancreatitis of rats. It was concluded that morphometric features of an intact part of the pancreas were not significantly changed with the use of tageflar. The intensity of 14C-leucine inclusion in the proteins of an intact part of the pancreas was strongly suppressed and the cytoplasm of exocrine pancreocytes was overloaded with zymogen granules. With the use of dalargin, a moderate hypertrophy of exocrine pancreocytes and intensification of 14C-leucine inclusion developed gradually. The number and disposition of zymogen granules were not significantly changed, as compared to acute pancreatitis. Both drugs disturbed the process of acinar reconstruction into tubular complexes in the marginal areas.
