Influence of Hypothermia and Cell Therapy on Structural Changes in Brain Tissues of Rats with Dyscirculatory Encephalopathy of Mixed Genesis
The study examines the morphological changes that occur in brain of SHR rats on the background of developing hypertensive dyscirculatory encephalopathy (DE), complicated by chronic alcohol intoxication (CAI). CAI has been proven to potentiate the progressive aging of brain in rats with hypertensive DE by aggravating its course and to lead to the development of DE of mixed genesis. The effectiveness of a single and combined use of rhythmic craniocerebral hypothermia (rCCH) and the introduction of cryopreserved cord blood nucleated cells (cCBNCs) to reduce the progressive vascular lesions of brain and the effects of chronic ischemia in animals with DE of mixed genesis. It has been proven that the combined use of rCCH and cCBNCs in the rats with a mixed DE had a more pronounced positive effect on morphological structure of brain tissues and vessels than their single use. There was a further decrease in the signs of dystrophic, destructive and pathologically altered compensatory adaptive processes in brain on the background of a significant decrease in neuroglial index, stimulation of angiogenesis, complete or partial absence of signs of smooth muscle cell hyperplasia, acute hemorrhages and ischemic strokes, spasms of arterial vessels’ walls and plethory in veins, that contributed to restoration of brain microhemocirculation and cytoarchitectonics.
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.
