I studied the changes in the intragastric temperature by introducing water into the stomach of healthy adults in comparison with those in the model experiments. Varying both temperature and volume of the water to be introduced, the following facts were confirmed.
1. The intragastric temperature abruptly drops or rises according to the temperature of the introduced water, but it does not reach the latter.
2. The recovery thereafter is expressed by an exponential function.
3. The time for recovery is practically decided by the time when the intragastric temperature returns within 0.1°C from the initial temperature.
4. The temperature of the introduced water essentially determines the change in the intragastric temperature immediately after the introduction of water and the volume of it governs the type of the recovery thereafter.
5. Those which deviate from the above cited relation between the intragastric temperature and temperature or volume of the introduced water seem to be due to the responses of the stomach itself under the control of the autonomic nervous system.
