Abstract
Responses of the intraduodenal temperature of healthy adults to subcutaneous injections of benzylimidasolin, histamine and posterior pituitary hormone, and intravenous injections of glucose, magnesium sulfate and sodium dehydrocholate were studied simultaneously with those of the intragastric temperature; and the following facts were confirmed.
1. The intraduodenal temperature is 0.1-0.4°C higher than the intragastric one, and it changes generally in parallel with the latter.
2. The intragastric and intraduodenal temperatures do not change significantly by glucose.
3. The both temperatures drop by histamine, benzylimidasolin and mag-nesium sulfate.
4. In each of the both temperatures, some differences are observed among the combinations of the type of change, the maximum drop and the time for reaching it by the three drugs.
5. The drop in the intraduodenal temperature by benzylimidasolin is preceded by a slight rise which does not appear in the intragastric one.
6. The both temperatures show retardation of the drop or a slight rise at the initial stage by magnesium sulfate.
7. The both temperatures rise slightly by posterior pituitary hormone.
8. The both temperatures change quite irregularly by sodium dehydrocholate.
