Effect of stimulation of vagus nerves on gastric tissue histamine concentration in albino rats

Summary 2 different time schedules were applied in order to stimulate vagus nerves around the oesophagus at the region of the cardio-oesophageal junction. The result shows a significant reduction in gastric tissue histamine concentration following vagal stimulation, the reduction being more when the duration of stimulation was longer.The authors are grateful to Dr V.
