BAYLISS, SIR WILLIAM MADDOCK


Meaning of BAYLISS, SIR WILLIAM MADDOCK in English

born May 2, 1860, Wolverhampton, Staffordshire, Eng.

died Aug. 27, 1924, London

British physiologist.

He and Ernest H. Starling studied nerve-controlled blood-vessel contraction and dilation and discovered the peristaltic wave. In 1902 they showed that dilute hydrochloric acid mixed with partly digested food activates a chemical in the duodenum that they called secretin, because it stimulates secretion of pancreatic juice. This marked the discovery of hormones, a term the men coined. Bayliss also showed how the enzyme trypsin was formed from inactive trypsinogen and measured precisely the time it took to digest protein. His recommendation of gum-saline injections for wound shock saved many lives in World War I.
