The amounts of heat generated by the tissue slices incubated with amino acid mixtures and glucose were measured by using a micro-calorimeter. The amounts of heat generated by the liver slices with amino acid mixtures were statistically greater than those generated with glucose. Each tissue of the various kinds of organs had a specific amount of heat generation depending upon the constituent of the nutrients. Intestine, pancreas and liver which are said to be the organs with a higher protein turnover rate, produced a greater amount of heat than the other organs, which suggests that the specific dynamic action might be significantly related to the protein synthesis of the organs. The fact that the specific dynamic action of the mixed diet of protein, carbohydrate and fat cannot be predicted from the mere individual percentage of each foodstuff might be explained as an effect that each organ or tissue has its own metabolism specific to each nutrient.
