Abstract
Summary
1. A new method of preventing coagulation of blood was devised by the employment of ion-exchange adsorbents. The principle is based on the replacement of the calcium ions in the blood with sodium ions. The most ideal of the ion-exchange agents was found to be a phenol-formaldehyde resin with a polyhydric phenol base. As a calcium-adsorbent the cation-exchange resin was employed in the sodium cycle. 2. Resin-treated blood was employed in hematological, serological and biochemical studies. Minimal alterations in cellular morphology were observed. 3. The resin is inexpensive and can be regenerated innumerable times and re-employed.
