Microencapsulation and Artificial Cells WHO International Programme on Chemical Safety - ein ThemaEarly studies by Pendleton and West (1) in 1932 demonstrated that urea moved from the blood into the small intestine in uremic dogs. In 1946, Twiss and Kolff (2) showed in uremic patients that urea could be removed when an isotonic solution was perfused through an isolated in testinalloop.
