- "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.
