PROTEIN METABOLISM FROM THE STANDPOINT OF BLOOD AND TISSUE ANALYSIS SECOND PAPER. THE ORIGIN AND SIGNIFICANCE OF THE AMMONIA IN THE PORTAL BLOOD

During the last few years London, together with Abderhalden and with various assistants, has published some forty papers on digestion and absorption. One of the points repeatedly emphasized in these communications is the conclusion that there is no absorption of digestion products from the stomach.’ They have made no attempt to explain and in fact have taken no notice of the more or less different results reported by earlier investigators,2 evidently assuming that their own results are so conclusive as to leave no room for any further difference of opinion on the subject. The methods used by Folin and Denis for demonstrating that amino-acids are absorbed unchanged from the small and from the large intestine (see the preceding paper) are equally applicable to the study of the absorption of nitrogenous products from the stomach and in this paper we wish to report some experiments which so far as we are concerned leave no room for doubt concerning the absorption of protein digestion products from the stomach. As in the previous work reported on the subject of absorption, cats were employed throughout. In every case the animal was anaesthetized by means of ether administered through a tracheal cannula and by a subcutaneous injection of morphine sulphate.
