Treatment of Diabetes with Insulin 
The reply to an inquiry about diabetes, 
given under “Health Notes,” on page 
1569, while accurate at the time that it 
was written, needs to be brought up to 
date in the matter of the use of insulin. 
This remedy became available for limited 
use in 1922, but only recently in sufficient 
quantity to place it within the reach of 
physicians and patients generally, at a 
reasonable price. The discovery of the 
substance called insulin is one of those 
achievements of modern medicine that take 
us from the commonplace almost into the 
realms of romance. Medicine had its 
origin in magic, and it has never entirely 
divested itself of mystery and supersti¬ 
tion. It is in our own generation that it 
has made the most rapid strides toward 
becoming an exact science, and there is 
no better illustration of this advance than 
the story of insulin. To relate the en¬ 
tire story would be to go back many 
years and trace the gradual adding of 
one discovered fact to another, until final¬ 
ly the genius of Dr. F. G. Banting and 
his Canadian associates assembled the 
known facts with regard to diabetes and 
devised means for making their knowledge 
of service to humanity. 
Sugar diabetes, as the disease is popu¬ 
larly called, is one of the scourges of our 
day, affecting, probably, a million people 
in this country alone. It is a disease in 
which the digestive organs lose their pow¬ 
er to take care of the sugars and fats in 
the food, and in which sugar accumulates 
in the blood and passes out with the fluid 
discharges from the body. The course 
and symptoms of the disease are only too 
well known, but the underlying cause has 
not yet been discovered. This much is 
known, however ; the seat of the disease 
is the pancreas, an organ lying behind 
the stomach, and called, in the lower ani¬ 
mals, the liver sweetbread. 
Like other glands concerned with di¬ 
gestion, the pancreas pours out into the 
digestive tract an important digestive 
fluid. This, for many years, was its only 
known function, though it was discovered 
a long time ago by a foreign investigator, 
named Langerhans, that the organ was 
not made up of one kind of tissue alone. 
Scattered through it were sections of dif¬ 
ferent structure from the rest of the 
gland, and these had no connection with 
the duct which led from the pancreas to 
the intestines. Clearly, as these sections 
had no outlet, they couldn’t be concerned 
in manufacturing the pancreatic fluid 
that was discharged through the duct 
leading from that organ. These isolated 
sections of the pancreas were called, after 
their discoverer, the islands of Langer¬ 
hans, but it was not until our own day, 
and after investigator after investigator 
had added his bit to knowledge of physi¬ 
ology, that it became clearly shown that 
these islands of Langerhans had a func¬ 
tion all their own, that function being to 
elaborate a digestive fluid which con¬ 
trolled the assimilation of the sugars and 
allied substances in the food and to turn 
this digestive fluid directly into the cir¬ 
culation through the blood vessels with 
which the islands were abundantly sup¬ 
plied. There are other ductless glands 
in the body, which, having no outlet, 
manufacture what are called “internal 
secretions” and get them into the blood 
stream in the same way ; the peculiarity 
about the pancreas is that it combines the 
two kinds of glands in one, a portion of 
it having an outlet through the pancreatic 
duct and other portions acting independ¬ 
ently to discharge their internal secretion 
directly into the blood vessels that perme¬ 
ate them. It is these latter portions, the 
so-called islands, that give the name to 
the product used in the control of dia¬ 
betes. The Latin word for islands is 
insula, and, as medical investigators have 
always been fond of Latin, they called 
the extract made from these islands “in¬ 
sulin.” 
To have learned that the islands of 
Langerhans in the pancreas were respon¬ 
sible for the digestion of sugar, and that 
their failure to act, through disease, was 
the cause of the symptoms of diabetes, 
was quite a different thing from getting 
hold of a pure secretion from these is¬ 
lands, however. No one had succeeded in 
doing it untH Dr. F. G. Banting, then a 
young assistant in the department of 
physiolo— of Western University, Can¬ 
ada, Happened, in November of 1920, to 
be reading an article in a journal of sur¬ 
gery that described the changes that took 
place in the pancreas when its duct was 
tied off. Chief of these changes was a 
degeneration of all the tissue of the pan¬ 
creas, except its islands; these latter, 
having no connection with the tied-off 
duct, would remain for a time healthy 
and continue to elaborate their secretion. 
It occurred to Dr. Banting that, if the 
pancreatic duct of one of the lower ani¬ 
mals was tied off and the animal allowed 
to live for a time, the secretion of the 
main body of the pancreas would disap¬ 
pear. while that of the islands would re¬ 
main. An extract then made from the 
gland would contain just what was want¬ 
ed, unmixed with other secretions that 
were not wanted. 
This idea seemed so feasible that it at 
once enlisted the support of others and, 
through the splendid team work of lab¬ 
oratory workers, chemists, physicians and 
commercial manufacturers of animal pro¬ 
ducts used in medicine, rhe correctness of 
Dr. Banting’s aswjmpikm was ifcmon- 
This spray 
is inexpensive , safe 
and easy to handle 
This new development in spray 
oil has been thoroughly tested 
by state experimental stations 
and private growers. It’s not an 
experiment. The results have 
been uniformly successful. 
You can mix this oil with any 
ordinary water and use this mix¬ 
ture alone or by adding Bordeaux, 
nicotine solutions or lead arsen¬ 
ate. It works well in any of these 
combinations for it’s both an in¬ 
secticide and a remarkable spread¬ 
er and sticker. 
It stays mixed and it “stays put” 
—resisting the washing action of 
rain. Brisk stirring by hand is 
enough to make it emulsify. 
Heat and special equipment are 
unnecessary. 
It’s action is safe and sure. It is 
harmless to use and clean to mix. 
It causes no harmful chemical re¬ 
actions—contains no chemicals. 
Sunoco gives a wonderful con¬ 
trol because it gets into all crevi¬ 
ces and crannies of bark and 
foliage. It is very inexpensive 
and it will not deteriorate from 
season to season, freeze, clog or 
corrode.
