Season changes in the pancreas from animals belonging to genuine deer subfamily have been investigated by histological, histochemical and biometric methods. Glycogen is not found in the pancreas cells throughout the seasons pointing to high functional activity of glandular cells, since glycogen is consumed for carbohydrate biopolymer synthesis and not accumulated. Depending upon the season, cytoplasm of pancreacells, cells of excretory ducts and pancreas islets showed different intensity of pyroninophilous reaction indicating RNA presence. These data coupled with the presence of protein in these cells demonstrate protein-synthesizing ability of the gland adapted to biorhythm. Changes in quantity and types of web cells as well as in functional activity of pancreacells and pancreas islets revealed season regularity and reflected functional lability of the cells and their constant involvement in many of vital important process.

Key words:  pancreas cells, islet cells, polyploidy, pyroninophilous reaction, total proteins, euchromatin, heterochromatin, excretory ducts, mucin, stroma, angioarchitectonics
