Ischemicko-reperfúzní poškození srdce u chladově adaptovaných potkanů / Ischemia-reperfusion injury in cold acclimated ratsVebr, Pavel January 2016 (has links)
The effect of cold acclimation on body of mammals has been studied for many decades by using relatively low temperatures for acclimation (6-10 řC). The results of these experiments have shown the important role of the adrenergic and thyroid system during acclimation and negative impact on renal system at the same time. In contrast, a recent study on winter swimmers suggests a possibility of positive influence of hardening on cardiovascular system. There is no available study investigating a relationship between cold adaptation and ischemia-reperfusion injury. The aim of this study was to establish a protocol of isolated rat heart and its fixation at our workplace. Furthermore, to find the impact of mild cold acclimation on the ischemia-reperfusion injury of rat. Methods of ex vivo heart perfusion and fixation were successfully established. The effect of 5 weeks long cold acclimation in 10 ± 2 řC on left ventricle ischemia-reperfusion injury was observed. Powered by TCPDF (www.tcpdf.org)
