Abstract
The aim of the work was to study the effect of modulation of B-lymphocytes activity with cholinotropic drugs on the stomach damage caused by water-immersion stress (WIS). The work was performed on male Wistar rats. Atropine (2 mg/kg), methacin (2 mg/kg) and choline alfoscerat (90 mg/kg) were administered 14 days before the WIS which lasted for 5 hours. The number of antibody-producing cells (APC) in spleen and the content of immunoglobulins IgA, IgG, IgM in blood were determined. The rats injected with saline were served as the control. On day 14 after administration of methacin or choline alfoscerat, but not atropine, an increase in the APC content in the spleen was observed comparing with control. At the same time, there was a significant decrease in the number of gastric ulcers. Thus on the model of water-immersion stress (WIS), it has been shown that B-lymphocytes can serve as a new target for the action of cholinotropic drugs, and modulation of their activity can provide effective prevention against stress.
