By the use of our newly divised apparatus, the intestinal bubble lift circulation apparatus for in-vitro use, we have conducted sinse 1965 a series of experiments on intestinal passage of insulin as an active polypeptides and of L-tryptophane as an amino acid as well as on active transport of glucose through the wall of everted intestine of the rat. A merit of the present apparatus is the elimination unexpected change in the perfusate, which is necessary for the evaluation of results by ultraviolet absorbance method. Furthermore, the use of everted intestine can exclude influence of resultant passive transport, by a hydrostatic fluid pressure, from serosal to mucosal side and solely active transport can be evaluated acculately. In the present report, also using the above apparatus, intestinal passage phenomena were investigated on the everted intestine of the rats which were previously fed by the various diets. On the other hand, the above rats were forced to swim up to exausted condition and for them the same phenomena was also studied. As the experimental results the acceralated intestinal passage of insulin and L-tryptophane was observed in group of low fat and protein diet (C_1), for its control. and L-tryptophane intestinal passage alone was enhanced in group of high fat and protein diet (A_1). In control group (B_2) and C_1 group, which were forced to swim, maked intestinal passage of insulin and L-tryptophane was observed. In A_1 group, however, it was inhibitory. In B_2 group, by addition of insulin to mucosal side, active transport of glucose was enhanced and futhermore by swimming exercise it was much more acceralated but by addition of L-tryptophane to the same side it was not enhanced, although L-tryptophane intestinal passage itself was acceralated. In A_1 group, by addition of insulin, acceralated transport of glucose was observed in spite of inhibitory insulin intestinal passage. The above obtain results are presumed to suggest that cell permeability of intestinal membrane could be selectively change due to the various kinds of condition mentioned above. Further studies on the present subject is now in progress.
