BACKGROUND
The pathophysiology of cerebral ischemia is essential for early diagnosis, neurologic recovery, the early onset of drug treatment and the prognosis of ischemic events. Experimental models of cerebral ischemia can be used to evaluate the cellular response phenomena and possible
Dimethyl sulfoxide (DMSO) is an organic compound widely used as solvent in biological studies and as vehicle for drug administration. DMSO has been shown to possess several biological effects, including antioxidant, anti-inflammatory, antinociceptive effects, and it has been proposed to be
Dimethyl sulfoxide (DMSO) has been reported to have beneficial effects in the treatment of central nervous system trauma, possibly due to its reported anti-inflammatory, antiedemic, anticoagulate, diuretic, hypothermic, vasodilatory, and respiratory stimulatory effects as well as an ability to
We investigated the cardioprotective efficacy of a new compound, 3-[(1H-1-indolyl)methyl] -4-amino 4,5-dihydro-1H,1,2,4 triazole-5-thione (C6458). The effect of C6458 on the reduction of the infarct size and its protective ability against oxidative damage of the myocardium after ischemia-reperfusion
BACKGROUND
Volatile anesthetics are known to protect the heart against ischemia-reperfusion injury. The authors tested whether anesthetic preconditioning with isoflurane is mediated via activation of the transcription factor hypoxia inducible factor 1 (HIF-1) and evaluated the role of mammalian
The object of this investigation was to study the effects of dimethyl sulfoxide (DMSO) upon the evolution of cerebral infarction. Twenty adult cats anesthetized lightly with ketamine hydrochloride underwent right middle cerebral artery occlusion for 6 hours. Ten cats were not treated and 10 cats
Dimethyl sulfoxide (DMSO) has a variety of biological actions that suggest efficacy as a neuroprotectant. We (1) tested the neuroprotective potential of DMSO at different time windows on infarct size using 2,3,5-triphenyltetrazolium staining and (2) investigated the effects of DMSO on ischemia
BACKGROUND
Ischemic preconditioning (IPC) and anesthetic-induced preconditioning against myocardial infarction are mediated via protein kinase B. Pim-1 kinase acts downstream of protein kinase B and was recently shown to regulate cardiomyocyte survival. The authors tested the hypothesis that IPC and
Cyclooxygenase (COX)-2 mediates ischemic pre- and postconditioning as well as anesthetic-induced preconditioning. However, the role of COX-1 and -2 in anesthetic-induced postconditioning has not been investigated. We evaluated the role of COX-1 and -2 in sevoflurane-induced postconditioning in vivo.
Cardioprotective properties of dimethyl sulfoxide (DMSO) were studied in the isolated rat heart model. Intraperitoneal administration of DMSO to animals for 3 days before the experiment, but not addition of DMSO to the perfusate, reduced infarction size. Both intraperitoneal and intracoronary
Hyaluronidase has been shown clinically and experimentally to reduce the effects of tissue ischemia in myocardial infarction and hemorrhagic shock. Dimethyl sulfoxide (DMSO) has been shown to reverse the effects of cerebral ischemia in the primate model. A caudally based dorsal skin flap in the rat
Acute arterial embolism continues to be a major cause of stroke morbidity in children and young adults. Potential therapy modalities include medical management and/or cerebral revascularization. The canine middle cerebral artery (MCA) was embolized by means of a pliable cylinder, 8 mm long by 1.6 mm
The aim of this study was to investigate the protective effect of necrostatin-1 on myocardial tissue of acute myocardial infarction (AMI) rats and to provide a basis for necrostatin-1 for the treatment of acute myocardial infarction. AMI rats (45) were established by ligating the anterior descending
