Abstract
Considerable work has been done in determining intragastric temperature under various conditions, but comparatively little attention has been paid to the liver. The following experiments were undertaken to determine the immediate temperature effect on the liver following the introduction into the stomach of water at a temperature of 3° C. Dogs were used for the purpose of these experiments and after having been starved for 20 hours were subjected to the following procedure.
Under ether anesthesia the abdomen was opened and thermometers placed as follows: one in the quadrate lobe of the liver, one suspended in the fundus of the stomach cavity, one inserted into a pocket in the stomach wall between the muscularis and the submucosa (except in dog number one this was not done) and of course a thermometer placed in the rectum at the time the anesthetic was started.
In order to introduce the ice-water directly into the stomach cavity a glass tube with the necessary rubber attachments was inserted near the cardiac end. The work was carried out at room temperature, in this case between 30° C. and 31° C., no artificial means being employed to maintain the body heat of the animals.
Temperature readings were taken every 30 seconds for a period of half an hour. The results are readily portrayed in1 the graphs and may be summarized as follows:
