Word History
angiotonin, an earlier name for the substance (from angio- + Greek tónos "stretching, strain, tension," alluding to its pressor effect + -in entry 1) + hypertensin, a synonymous name, from hypertens(ion) + -in entry 1, after Spanish hipertensina — more at tone entry 1
Note: The term angiotonin was introduced by the American physiologist Irvine H. Page (1901-91) and biochemist Oscar M. Helmer in "A crystalline pressor substance (angiotonin) resulting from the reaction between renin and renin activator," Journal of Experimental Medicine, vol. 71, No. 1 (January 1, 1940), pp. 29-42. The etymology is stated explicitly: "For this substance we suggest the name 'angiotonin' [Greek ἀγγεῖον, blood vessel, + τόνος (τείνω), strain]" (p. 29). Spanish hipertensina was introduced by the Argentine physiologist Eduardo Braun-Menéndez (1903-59) and coworkers in "La sustancia hipertensora de la sangre del riñón isquemiado," Revista de la Sociedad Argentina de Biología, vol. 15 (1939), pp. 420-25. Page and Braun-Menéndez later agreed to merge the two synonymous names into angiotensin; see "Suggested Revision of Nomenclature—Angiotensin," Science, vol. 127, Issue 3292 (January 31, 1958), p. 242.
