“…Despite a meticulous microvascular surgical technique and well-functioning feeding vascular anastomoses, ischemia and reperfusion might induce perfusion failure and severe tissue damage. The mechanisms underlying these changes are still a subject of debate, but several observations suggest that ET-A receptor activation is critically linked to the microcirculatory derangement in the reperfused tissues (12,22).…”

“…Ezt támasztja alá, hogy korábbi vizsgálatok igazolták, hogy hasonló körülmények között az ET-A receptor gátlása képes javítani a zsigeri keringést. 18 A késői hemodinamikai változásokat patkányokon végzett kísérleteink során fi gyeltük meg, ezek hasonlóak voltak a szisztémás gyulladásos válaszban leírt változások-hoz, amely miatt lényeges különbségeket fi gyeltünk meg a sertésekben mért akut változásokhoz képest. A NOMI indukcióját követő napon, annak ellenére, hogy a MAP a normáltartományban volt, a HR és a CO szignifi kánsan megemelkedett.…”

“…During the reperfusion phase, the mesenteric blood flow decreases, the mesenteric vascular resistance increases, and the accumulation and free radical production capacity of the leukocytes rises (25). The elevated level of reactive oxygen species (ROS) plays a central role in this phase of the ischemia/reperfusion (IR) process (26,27).…”

“…Nevertheless, in the AcPepA-treated group, the SMA flow was significantly elevated at the beginning of the post tamponade phase, and gradually returned to the control level by the end of the experiments. This early flow elevation may be attributable to the relative lack of vasoconstrictor ET-1 effects because it has been demonstrated that ET-A receptor inhibition is able to improve the splanchnic circulation in similar cases (25).…”
