Drs. J.J.R. Macleod & F.G. Banting
(APRIL 21, 1923)
"Insulin," perhaps the most widely heralded medical discovery of the
past year, continues to show promise, though its originators claim
only that it has alleviated some cases and enabled patients to
assimilate a more normal diet. Insulin was evolved by Drs. J.J.R.
Macleod and F.G. Banting, of the physiological department, University
of Toronto. It is extracted from the pancreas glands of sheep or
beeves, and is named from the "islands of Langerhans"--little spots of
vascular tissue through which the internal secretion of the pancreas
passes into the blood. In normal health this secretion regulates the
assimilation of sugar in the diet. Production of insulin on a large
scale is difficult and expensive. Its manufacture is strictly safe-
guarded under patents held by the University of Toronto, and it is
made by only one firm in the United States. It is administered,
hypodermically.
