Cryogenic preservation of rat polymorphonuclear leukocytes. 1980

H L Bank, and L Buchner, and H Hunt

Rat polymorphonuclear leukocytes (PMNs) were frozen to --196 degrees C, thawed, and tested for functional viability using a variety of criteria, which included: qualitative and quantitative nitroblue tetrazolium assays, fluorometric membrane integrity assays, chemotactic assays, and bactericidal assay. Using these criteria, the survival of rat PMNs obtained from a glycogen-induced peritoneal wash averaged approximately 70% after thawing. The survival of PMNs obtained from rat peripheral blood was greater than 95%. Maximal survival for cryopreservation of these cells frozen in the presence of 10% dimethyl sulfoxide and 5% hydroxyethyl starch was obtained when the cells were cooled at approximately 10 degrees C/min.

D001770 Blood Bactericidal Activity The natural bactericidal property of BLOOD due to normally occurring antibacterial substances such as beta lysin, leukin, etc. This activity needs to be distinguished from the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy, which is measured by a SERUM BACTERICIDAL TEST.

D001793 Blood Preservation The process by which blood or its components are kept viable outside of the organism from which they are derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).

D002470 Cell Survival The span of viability of a cell characterized by the capacity to perform certain functions such as metabolism, growth, reproduction, some form of responsiveness, and adaptability. Cell Viability,Cell Viabilities,Survival, Cell,Viabilities, Cell,Viability, Cell
D002498 Centrifugation Process of using a rotating machine to generate centrifugal force to separate substances of different densities, remove moisture, or simulate gravitational effects. It employs a large motor-driven apparatus with a long arm, at the end of which human and animal subjects, biological specimens, or equipment can be revolved and rotated at various speeds to study gravitational effects.

D004121 Dimethyl Sulfoxide A highly polar organic liquid, that is used widely as a chemical solvent. Because of its ability to penetrate biological membranes, it is used as a vehicle for topical application of pharmaceuticals. It is also used to protect tissue during CRYOPRESERVATION. Dimethyl sulfoxide shows a range of pharmacological activity including analgesia and anti-inflammation.
