Paulescu's discovery of insulin

In 1916, he succeeded in developing an aqueous pancreatic

, he resumed his research and succeeded in isolating the antidiabetic pancreatic hormone (pancreine).

From April 24 to June 23, 1921, Paulescu published four papers at the Romanian Section of the Society of Biology in Paris

:
  • The effect of the pancreatic extract injected into a diabetic animal by way of the blood.
  • The influence of the time elapsed from the intravenous pancreatic injection into a diabetic animal.
  • The effect of the pancreatic extract injected into a normal animal by way of the blood.


An extensive paper on this subject - Research on the Role of the Pancreas in Food Assimilation - was submitted by Paulescu on June 22 to the Archives Internationales de Physiologie in Liège, Belgium

, and was published in the August 1921 issue of this journal.

The method used by Paulescu to prepare his pancreatic extract, as published in the Archives Internationales de Physiologie in 1921, was similar to a procedure described by the American researcher Israel S. Kleiner in an article published in 1919 in Journal of Biological Chemistry. Using his procedure, Kleiner had been able to demonstrate significant reductions in the concentration of blood and urinary glucose after intravenous injections of his extract.

Furthermore, Paulescu secured the patent rights for his method of manufacturing pancreine (his own term for insulin

) on April 10, 1922 (patent no. 6254) from the Romanian Ministry of Industry and Trade.

Nobel Prize controversy

Eight months after Paulescu's works were published, doctor Frederick Grant Banting and biochemist John James Rickard Macleod from the University of Toronto

) in diabetic dogs. Their paper is a mere confirmatory paper, which made direct references to Paulescu's article but misquoted that article as follows:

"He [Paulescu] states that injections into peripheral vein

s produce no effect and his experiments show that second injections do not produce such marked effect as the first
",


Which is not what Paulescu found out or presented. Later on, Banting said that

"I regret very much that there was an error in our translation of Professor Paulescu's article, I cannot recollect, after this length of time, exactly what happened (...) I do not remember whether we relied on our own poor French or whether we had a translation made. In any case I would like to state how sorry I am for this unfortunate error (...)"


While Paulescu had patented his technique in Romania, no clinical use resulted from his work. The work published by Banting, Best, Collip and McLeod represented the injection of purified insulin extract into a diabetic individual ameliorating symptoms of the disease. Not surprisingly, Banting and Macleod received the 1923 Nobel Prize in Physiology or Medicine

 for the discovery of insulin. While it seems fair to say that Paulescu deserved to share in the prize, so did Collip and Best, who were left out (Banting and McLeod decided to share the prize money with them). International recognition for Paulescu's contribution to the discovery of insulin came only years later.

Professor Ian Murray was particularly active in working to correct "the historical wrong" against Paulescu. Murray was a professor of physiology at the Anderson College of Medicine in Glasgow

. In an article for a 1971 issue of the Journal of the History of Medicine and Allied Sciences, Murray wrote:

"Insufficient recognition has been given to Paulesco, the distinguished Roumanian scientist, who at the time when the Toronto team were commencing their research had already succeeded in extracting the antidiabetic hormone of the pancreas and proving its efficacy in reducing the hyperglycaemia in diabetic dogs."

, and wrote extensively for the latter's newspaper Apărarea Naţională.

In "Degenerarea Rasei Jidanesti" (1928) (transl. Degeneration of the Jewish Race") Paulescu states that Jews are degenerate because their brains weigh much less than "Arian" brains. He singles out for their low brain weight the Nobel Prize laureates Anatole France, Albert Einstein and Henri Bergson.
