摘要

定量分析犬小腸各成分，即縱肌、環行肌、粘膜帶粘膜下組織，並由適宜標本的長、寬、重量、比重、水和脂肪、膠性蛋白、彈性蛋白的含量，推算出犬小腸在不同位置各成分之厚度，去粘膜肌後粘膜帶粘膜下組織的比重，脫脂後比重，水和脂肪的分佈，脫脂後水分的分佈以及膠性蛋白和彈性蛋白濃度的變異等。水、脂肪、膠性蛋白和彈性蛋白沿腸道的變異，支援以往的推定在構造上無順序差異的論據，而波動的脂肪濃度不但干擾水分的分佈，或亦影響其他化學成分的分佈。各成分厚度不同指明等寬等重標本所佔小腸的長度不能相同。其他有關各點，曾經分別予以討論。

並列摘要

Quantitative studies were made of the elements of dog's intestine, viz., the longitudinal and circular muscle and the mucosa with submucosa. From the width, length, weight, specific gravity, amount of water and fat and concentration of collagen and elastin of appropriate samples, the thickness, the specific gravity of the mucosa with submucosa less muscularis mucosae, fat-free specific gravity, water content, fat% distribution, fat-free water content, variation in concentration of collagen and elastin in practically every element of the intestine at different levels were derived. While variation of water, fat, collagen and elastin along the intestine gave support to a previous finding in which the non-segmental gradient conception in structure was suggested, the fluctuation of fat concentration disturbed not only the water distribution, perhaps also the other chemical compositions. Difference in thickness of the different elements leads to the finding that each element of equal weight and width does not cover the same length of the intestine. Other pertinent points were discussed.
