Abstract
Here, we have studied the osmotic parameters of erythrocytes frozen in the composition-modified media with glycerol and 1,2-propanediol. A decreased glycerol concentration in a cryopreservative and an increased content of impermeable protective component sorbitol were established to affect the erythrocyte characteristics at different stages of freezing and hypothermic storage. Reduction of 1,2-propanediol and NaCl concentrations when augmenting the sucrose content in cryopreservative agent enabled changing a two-stage mode of erythrocyte freeze-thawing to the single-stage one. The presented here modification of cryoprotective medium allowed to diminish the level of damage to erythrocytes during freeze-thawing-washing out, that might prevent the inflammation development in a body when transfusing these cells.
期刊介绍：
The Journal publishes the reviews and original papers on cryobiological and cryomedical research, in particular the elucidation of mechanisms of injuries occurring in biological objects and caused by the influence of low and ultra low temperatures; natural resistance of biologicals to cold and their recovery post effect; the development of effective methods of cryoprotection and technology of storage of biological resources under hypothermic and ultra low temperatures, application of hypothermia, cryotherapy and cryopreserved biologicals for treating various pathologies; cell and tissue based therapies and other issues of low-temperature biology and medicine, as well as development of devices and equipment for low temperature biology and medicine. The journal covers all topics related to low temperature biology, medicine and engineering. These include but are not limited to: low temperature storage of biologicals (human, animal or plant cells, tissues, and organs), including preparation for storage, thawing/warming, cell and tissue culturing etc. response of biologicals to low temperature; cold adaptation of animals and plants; utilisation of low temperature in medicine; experimental and clinical transplantation, cell and tissue based therapies; developing of cryobiological and cryomedical devices; organisation and functioning of low temperature banks etc.
