We investigated the metabolism of mouse isolated heart under influence tricarbonyldichlorothenium (II)- dimer (CORM-2 and 2,3-4,5-bis-O-isopropylidene-βD-fructopyranose sulfamate (topiramate) as potential blockers aquaporine channel (AQP3) cardiac myocytes. The results were compared with those obtained from group receiving anti-AQP3 monoclonal antibodies. A decrease in coronary flow was found d...
background: central renin angiotensin system has an important role on the cerebral microcirculation and metabolism. our previous work showed that inhibition of angiotensin converting enzyme (ace) activity prior to induction of ischemia protected the brain from severe ischemia/reperfusion (i/r) injuries. this study evaluated the impacts of post-ischemic inhibition of ace, enalapril, on brain inf...
Background: Renal injuries associated with ischemia/reperfusion are a prevalent clinical phenomenon that can cause the emergence of progressive kidney diseases, eventually leading to chronic kidney injuries. The present study was conducted to evaluate the results obtained from non-invasive imaging using small-animal SPECT and investigate the recovery process in an animal model of renal ischemia...
Lee, H. Thomas, and Charles W. Emala. Protective effects of renal ischemic preconditioning and adenosine pretreatment: role of A1 and A3 receptors. Am. J. Physiol. Renal Physiol. 278: F380–F387, 2000.—Renal ischemia and reperfusion during aortic and renal transplant surgery result in ischemic-reperfusion injury. Ischemic preconditioning and adenosine infusion before ischemia protect against isc...
Background and Objective: Ischemia reperfusion plays a major role in the development of pathological alterations in many different neuropathies. In this study, we evaluated the role of aminoguanidine (AG) in the functional recovery of the rat re-perfused sciatic nerve based on the behavioral scores. Materials and Methods: Seventy two rats were divided into 12 groups (n = 6). We used ischemic mo...
Objective(s) Dracocephalum moldavica (D. moldavica) have been traditionally used as a cardiotonic agent in the folk medicine of some regions of Iran. In the present study, effects of total extract of D. moldavica on ischemia/reperfusion induced arrhythmias and infarct size investigated in isolated rat heart. Materials and Methods The isolated hearts were mounted on a Langendorff apparatus th...
BACKGROUND Ischemic pre- and postconditioning protects the liver against ischemia/reperfusion injuries. The aim of the present study was to examine how ischemic pre- and postconditioning affects gene expression of hypoxia inducible factor 1α (HIF-1α), vascular endothelial growth factor A (VEGF-A) and transforming growth factor β (TGF-β) in liver tissue. METHODS 28 rats were randomized into fi...
OBJECTIVE Ischemic preconditioning and some drugs can protect tissues from injury by preserving microcirculation. This study evaluated vascular permeability in a hamster cheek pouch preparation using either short ischemic periods or bradykinin as preconditioning stimuli followed by 30 min of ischemia/reperfusion. METHOD Sixty-six male hamsters were divided into 11 groups: five combinations of...
Background and Aim: Stroke is the third leading cause of death and the most important factor of disability in the world. Recent studies have shown that olive oil has antioxidant effects during cerebral ischemia. The present study investigated the probable protective effects of olive oil on the brain infarction and neurological disability after a transient model of focal cerebral ischemia/reperf...
OBJECTIVES Intestinal ischemia/reperfusion often leads to acute lung injury and multiple organ failure. Ischemic preconditioning is protective in nature and reduces tissue injuries in animal and human models. Although hematimetric parameters are widely used as diagnostic tools, there is no report of the influence of intestinal ischemia/reperfusion and ischemic preconditioning on such parameters...
