Abstrakt: The decrease of major cytoplasmic membrane phospholipids (phosphatidylcholine and phosphatidylethanolamine) content was established in mucosal epithelial cell under colon inflammation pathology--ulcerative colitis. It was shown that aforementioned changes were associated with the increase of phospholipids' hydrolyzing enzyme--phospholipase C activity and intracellular Ca2+ concentration enlargement. Carcinogenesis stimulation under inflammation was accompanied by phospholipase C activity increase when quantity of investigated phospholipids (phosphatidylcholine, phosphatidylinozytol, phosphatidylserine) separately decreased and cytoplasmic Ca2+ value normalization was established.
