An infarct is an area of ischemic necrosis caused by occlusion of either the arterial supply or the venous drainage in a particular tissue. ... (Fig. 4-19). The brain is an exception to these generalizations; ischemic tissue injury in the central nervous system results in liquefactive necrosis (Chapter 1). ... though hardier than neurons, are ...

Myocardial ischemia–reperfusion (IR) injury is considered as a pathophysiological process wherein the ischemic tissue suffers from undesirable outcomes when occlusive coronary artery restores blood flow and oxygen and nutrients are subsequently supplied after several clinical events, such as myocardial infarction, stroke, cardiac arrest and ...

To determine the susceptibility to I/R injury, infarct size was measured. The AAR was similar in both groups, indicating the same ischemic area and reproducibility of ligature. Consistent with cTn-I level, silibinin treatment significantly decreased infarct size in comparison with vehicle (20.5±1.3% vs. 35.9±2.5%) (Fig. 2A, B).

In this experiment, gastrodin (50mg/kg) which could remarkable reduce the cerebral infarct volume were used to treat cerebral ischemia-reperfusion injury. The effect of gastrodin on amino acids in striatum in the rats of cerebral ischemia-reperfusion injury was investigated.

The current, established clinical treatment to limit myocardial infarct size and improve outcome post-MI is timely restoration of blood flow to the ischemic territory. Reperfusion has, however, been termed a ‘double-edged’ sword: i.e., while early reflow undoubtedly salvages populations of ischemic myocytes, reperfusion per se has also been ...
