title: Radioprotection of sheep erythrocytes by polyvinylpyrrolidone.
abstract: The protective effect of polyvinylpyrrolidone of mol. wt 10,000 and 40,000, on sheep erythrocytes irradiated up to 13 kGy, and stored for one month at 4 degrees C was studied. Addition of these compounds at a level of 10-15% reduced hemolysis from 90% in irradiated erythrocyte solution to approximately 10%. The high efficiency of this protective agent is discussed.
