He opined that Banting's hypothesis that duct ligation was necessary for trypsin-producing cells to atrophy before making an extract of the internal secretion was false.
In 1906, Moore, Edie and Abram (2) at the Royal Infirmary in Liverpool, England, proposed that the "duodenum supplies a chemical excitant for the internal secretion of the pancreas and that in certain cases of diabetes, the appearance of sugar in the urine might be due to functional disturbance occasioned by the absence of such an intestinal excitant.
This discovery directed closer attention to the islets as the probable source of an internal secretion of the pancreas necessary for normal metabolism of sugar and lacking in diabetes.
