[The problem of sugar resorption in the small intestine: histochemical studies by means of the Gomori method]

The role of alkaline phosphatase during active absorption of sugars is experimented with Gomori's histochemical method. Experiments on empty intestine show that the surgical intervention does not alter the phosphate content of the wall of the small intestine. Absorption experiments with 10% and 5,4% (isotonic) glucose solutions demonstrate a marked decrease in the alkaline phosphatase content of the wall of the small intestine. In half of the cases only, absorption experiments with a 10% mannitol solution determine a small decrease in the alkaline phosphatase of the wall of the small intestine. In 90% of the cases, there are lesions of the intestinal epithelium.
