Abstract : Damage to blood cells in blood taken with the usual glucose-citrate solution with out the addition of protective substances, occurs during the process of freezing and thawing, apparently, occurs essentially during the stage of thawing. Ethyl alcohol, used as a protective substance, in a complex glucose-citrate solution, protects to a certain degree, the blood cells during the process of freezing and thawing in spite of intensive re-crystallization, even at relatively low temperature. In the concentrated solution, containing two protective substances (ethyl alcohol and glycerine), the process of recrystallization is weak. At temperatures to -50C a considerable portion of the solution remains non-crystallized and fills up the canals between the crystals in which there are present some mobile cells. (Author)
