[The functional and reserve potentials of the absorption processes in the small intestine in a nutritional disorder].

The absorbing function of the small intestine was studied in healthy subjects and those patients with chronic gastritis presenting with lower than the normal body mass, than of above normal, and normal, with the aid of the D-xylose test alone and in combination with atropine, lactose, amino acids, intralipid. The data obtained suggest functional and reserve inadequacy in those individuals with nutritional disorders presenting as deficit in respect of body mass of alimentary- and-constitutional genesis.
