采用Van Loon法测定了大鼠、小鼠、狗、豚鼠和鸡血清及其他组织中淀粉酶的浓度。在切除胰腺和唾液的大鼠中进行的类似测量表明，这种手术并没有降低淀粉酶的浓度。计算表明，这些动物肝脏中的一些淀粉酶是细胞内的。除肌肉和胰腺外，组织和血清淀粉酶活性在pH为7.0的磷酸盐和pH为7.6的横向缓冲液中基本相同。在狗的肺部血液中没有检测到淀粉酶。
Using Van Loon''s amyloclastic method, amylase concentrations in the sera and various other tissues of the rat, mouse, dog, guinea pig and chicken were determined. Similar measurements in pancreatectomized-salivarectomized rats showed that such surgery did not result in lowered amylase concentrations. Calculations indicate that some of the amylase in the livers of these animals is intracellular. Tissue and serum amylase activities are essentially the same in pH 7.0 phosphate and pH 7.6 Veronal buffers, except for muscle and pancreas. No detectable amylase was added to the blood in passage through the lungs in the dog.
