A METHOD FOR RECORDING GASTRIC SECRETION IN ACUTE EXPERIMENTS ON NORMAL ANIMALS

Robert K. S. Lim 1

1 The Department of Physiology, University of Edinburgh

A method for recording gastric secretion in normal anaesthetised animals is described. It depends on the use of a perforated glass cannula (introduced into the stomach through the pylorus) to drain the stomach of its juice, which is allowed to activate a drop-recorder after its escape from the organ. A balloon is also inserted into the stomach to serve as a control of motor changes.

The method permits of observations being made on the latent period, the duration and the quantity of secretion after the introduction of a suitable excitant. The juice thus obtained invariably contains free HCL and pepsin.
