INTRACELLULAR INORGANIC IONS AND AMINO-ACID POOL IN ISOLATED INTESTINAL MUCOSA OF TORTOISE TESTUDO HERMANNI HERMANNI GMELIN

In order to study the intracellular composition of the intestinal mucosa, the first step consists of the determination of the extracellular space. A previous work (Gilles-Baillien, 1968) has shown that the extracellular space of the small intestine mucosa is close to 10% (ml/g wet weight) and is the same at the different levels of the small intestine, while it is between 6 and 10% (ml/g wet weight) in the colon mucosa. Knowing, in addition, the water content, an estimation can be given of the intracellular concentrations in Na, K, Ca, Cl, taurine, urea and amino acids, at different levels of the intestinal tract, in the single mucosa. © 1969 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
