Cardioprotective Effect of Low Molecular Weight (Below 5 kDa) Fraction of Cattle Cord Blood Cryohemolysate
In this report, we have studied a cardioprotective effect of low molecular weight (below 5 kDa) fraction derived from cattle cord blood in a rat model of infarction-like cardiovasopathy. The myocardial infarction development was initiated in the animals, maintained for two months on a diet with excessive intake of fat, calcium and sodium salts, by making hypoxia-hypercapnia in them. The use of this model allowed inducing the infarction-like cardiovasopathy, comparable by many respects with the clinical picture of myocardial infarction, which was confirmed by electrocardiography, enzyme-linked immunosorbent assay and histological analysis. Preliminary administration of low molecular weight (below 5 kDa) fraction of cattle cord blood, as well as Actovegin did not prevent the heart attack, but increased the endurance of rats to hypoxia-hypercapnia and reduced the damage rate to myocardium. A preventive administration of low molecular weight fraction of cord blood was proven to mitigate the risk of hypoxia-induced damages to myocardium.
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.
