Bernard showed that if sucrose is injected directly into the blood it is eliminated by the kidneys while glucose is retained, and that gastric juice transforms sucrose into assimilable sugar. See F. J. Holmes, Claude Bernard and animal chemistry: The emergence of a scientist, Cambridge, Mass., 1974. This includes a history of research on digestion from 1750-1848.

Bernard’s first communication regarding his investigation of the glycogenic function of the liver. Reprinted, with translation, in Med. Classics, 1939, 3, 552-80.

Discovery of the digestive action of the pancreatic juice, especially its role in the digestion and absorption of fats. Reprinted, with translation, in Med. Classics, 1939, 3, 581-617.

By experimental puncture (piqûre) of the fourth ventricle of the brain, Claude Bernard produced temporary glycosuria.

Bernard discovered the existence of vasomotor nerves.

This record of Bernard's actual lectures contains the first published description of Bernard's technique of right and left heart cathererization, a technique that Bernard invented. The appendix includes notes of lectures by Charles Robin. Digital facsimile from the U.S. National Library of Medicine at this link.

Bernard published a detailed account of the procedure in "Recherches experimentales sur la temperature animale," Comptes rendus Acad. Sci, 43, 551-569. He undertook the proceedure in an attempt to study the difference in temperature between the two circulations.

Claude Bernard made strenuous efforts to introduce experimental methods into physiology. The above includes his classic work on the function of the liver, pancreas, and gastric glands. Vol. 1, p. 126: Catheterization of the heart of a dog (in some editions, p. 119). See also No. 634.

The culmination of Bernard’s work on the glycogenic function of the liver. He invented the term “internal secretion” and can be said to have started the scientific investigation of the internal secretions, although for 30 years the significance of his work was not generally realized. By his research on glycogen Bernard showed that the body can not only break down, but can also build up, complex chemical substances.

Bernard paralysed motor nerve-endings with curare and demonstrated the independent excitability of muscle. He showed that curare acted by stopping the transmission of impulses from motor nerves to voluntary muscles.

The most beautifully illustrated of all Bernard’s writings, which summed up the results of his work on the role of the pancreas in digestion. English translation as Memoir on the pancreas, and on the role of pancreatic juice in digestive processes, particularly in the digestion of neutral fat,  translated by John Henderson, reproducing the color plates in color. London, 1985.

Bernard included a summary of his experiments with curare in the Leçons to establish his priority in researching its effects. He demonstrated in these experiments the susceptibility of the nerve-muscle preparation to a chemical (pharmacological) effect.

Isolation of glycogen. See also C. R. Acad. Sci. (Paris), 1857, 44, 578-86, 1325-31.

Discovery of the vasoconstrictor and vasodilator nerves and description of their function of regulating the blood supply to the different parts of the body.

Bernard was the first to describe an effect of the renal nerves on urine flow.

Studies of the “paralytic secretions” occasioned by section of glandular nerves.

Probably the greatest classic on the principles of physiological investigation and of the scientific method as applied to the life sciences. English translation, New York, 1927. See P.F. Cranefield, Claude Bernard’s revised edition of his Introduction à l’étude de la médecine expérimentale, New York, 1976.

An elaboration of his lectures on the subject at the Collège de France.

As early as 1864 Bernard discovered that chloroform anesthesia could be prolonged and intensified by the injection of morphine. J. N. von Nussbaum also observed this. English translation by B. Fink, Park Ridge, 1989.

Bernard showed that in diabetes there is primarily glycemia followed by glycosuria.

Bernard disbelieved Pasteur’s definition of a ferment as “a living form originating from a germ”.

Auction catalogue of Bernard's library conducted by Bernard's publisher and bookseller, J.-B Baillière et Fils.  The sale, conducted over 4 days, included 1077 lots. Most were books published during Bernard's lifetime. Bernard did own a few antiquarian anatomical works, including a Vesalius Epitome (1543) but no Fabrica.

In this, his last work, Bernard showed himself “the unapproachable master in the technique of experimental procedure” (Garrison).
