Surface Ionic Changes and the Coagulation of Blood. D. HUBBARD AND G. L. LUCAS (J. appl. Physiol., March, 1960) report some observations on the phyaico-chemical role played by glass surfaces in accelerating the .. normal " coagulation rate of blood, in light of the non-migratable negative ionic change which appears on leached glass surfaces and the orientation of the positively charged calcium ion of the blood at the fluid glass interface. Numerous other materials such as artificial arteries, heart valves, bandages, clays, tobacco, tea leaves, spider web, coffee grounds, and so on, as well as "live" skin, have been investigated with respect to the ionic nature of their surfaces and their effect on blood coagulation. An effort was made to establish the ionic charge of the endothelial layer of the circulatory system; however, the procedure used in this investigation does not lend itself to in-vivo or even convincingly to in-vitro determinations. The ionic nature of the material was determined from the uneven distribution of Ag(NH3) + and Bions in full strength aqueo~ ammonia caused by the non-migratable ionic charge characteristics of the surfaces.
