Claude Bernard attributed a fundamental role in experimental medicine to the "contre-épreuve." He believed that a phenomenon fails to appear if its cause is eliminated (contre-épreuve). Therefore, the relation "preuve-contre-épreuve" emerges as the best criterion of experimental truth. In 1848 Claude Bernard discovered that pancreatic secretion could emulsify and saponify fatty substances. This article, based on his original manuscripts, shows that Bernard demonstrated in 1851 that the absence of pancreatic juice resulted in the arrest of fat digestion. Using the "contre-épreuve," he destroyed the pancreas in dogs as another way to prove his theory of the pancreatic digestion of fat.
克洛德·贝尔纳认为“反证法”在实验医学中起着根本性作用。他认为，如果某一现象的原因被消除（反证法），那么该现象就不会出现。因此，“证明—反证”关系成为实验真理的最佳标准。1848年，克洛德·贝尔纳发现胰腺分泌液能够乳化并皂化脂肪物质。本文基于他的原始手稿，表明贝尔纳在1851年证明了胰液缺失会导致脂肪消化停止。他采用“反证法”，通过切除狗的胰腺作为另一种方式来证明他的胰腺消化脂肪的理论。
