Peculiarities of values of acetylcholine concentration and cholinesterase activity in serum of patients with alcoholic chronic pancreatitis and duodenal ulcer

Introduction. There are a lot of pathogenic factors involved in development of polyetiologic diseases. Acetylcholine (AC) is known as first-order mediator as it plays an important role in development and maintenance of pathological processes. In this article we provide data on AC concentration in blood serum of patients with duodenal ulcer, alcoholic chronic pancreatitis and control group as well as activity of cholinesterase. The aim of this study was to identify a role played by AC in pathological process during disease, which may complicate a course of the disease as a bad prognostic factor. Results and discussion. We divided AC concentration into three types in the control group: low — 0.46–1.0 mmol/l (60% of individuals), moderate — 1.02–1.5 mmol/l (30%) , and high — more than 1.5 mmol/l (10%). Conclusion. We suppose that cholinesterase activity and AC concentration depend on localization of pathological process.
