[Changes in the content of nucleic acids and total protein in exocrine pancreatocytes and the composition of their population in experimental acute pancreatitis in rats].
Using cytophotometry, contents of DNA, RNA and total protein were measured in the rat's exocrine pancreatocytes (EP) in normal conditions and at different stages of pancreatitis induced by cooling the spleen part of the pancreas with chlorethyl. In the duodenal (not damaged) part of the pancreas some drastic changes in the EP ploidy distribution were shown to occur. They led to the formation of a qualitatively new population pattern with 4c and 2c + 2c cells prevailing (more than 60% of the total content), which are by 1.5-3 times more active in RNA and protein synthesis and accumulation than the normal cells. The population structure rearrangement in the EP and their functional activity rise took place at two stages. At the first one the intracellular defense mechanisms of the EP in response to acute necrobiotic processes in the pancreas tissue were activated, at the second one the supracellular mechanisms regulating synthetic processes leading to a rapid adaptation of viable EP to new conditions were switched on.
