[French scientific contributions to anesthesia. Curares and the neuromuscular junction].

In France, a number of scientists from the fields of chemistry, physiology and surgery have been interested in anaesthesiology. Claude Bernard, who published in 1872 the most exhaustive studies on anaesthesia, was also interested from 1844 in drug curare. He created a methodology, studied pharmacology, including pharmacokinetics and demonstrated the specific action on motor nerves while muscle retained its irritability. It was however A. Vulpian who put forward the idea that curare does not affect the nerve itself but may act on a "linking substance" between nerve and muscle. In these times (1862), Rouget described the end apparatus at the nerve-muscle junction in a way which was finally accepted by German authors. Fifty years later, Couteaux achieved the microanatomic study of the end plate (1909). More recently (1972), Changeux and his team isolated the acetylcholine receptor from the electric organ of the torpedo fish.
