Background:Troxerutin has antioxidant and anti-inflammatory properties and in this study, its antioxidant effect on the reduction of oxidative stress induced by ischemia-reperfusion sciatic nerve injury was investigated. Methods:In this study, 64 male rats were randomly divided into 8 groups as follows: 1- IR2: ischemia (3 hours) and reperfusion (2 days), 2- T...
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...
Background and Objective: Ischemia plays a major role in development of pathological changes in various neuropathies. Reperfusion amplifies physiological and pathological abnormalities in ischemic nerves. In this research, we studied ischemic-reperfusion (IR) injury of sciatic nerve up to 14 days of reperfusion. Materials & Methods: IR was produced by ligation and release of nooses around suppl...
Introduction: Stroke is a neurological disease and one of the leading causes of death all over the world. It is also an important cause of disability in people over age over 65. It may be possible to reduce the incidence of cerebral ischemia using antioxidants, followed by inhibition of oxidative and inflammatory mechanisms. Troxerutin is a natural bioflavonoid with antioxidant and anti-inflamm...
A rat model of severe nerve ischemia was used to study the effects of ischemia and reperfusion on nerve conduction, blood flow, and the integrity of the blood-nerve barrier. Conduction failure was consistently found in the sciatic-tibial nerve during 1- and 3-hr ischemic periods. Recovery of the compound muscle action potential was prompt and complete upon reperfusion following 1 hr of ischemia...
BACKGROUND Alpha lipoic acid is a potent antioxidant that plays numerous roles in human health. This study examined the effect of ALA on rat sciatic nerve ischemia reperfusion damage. AIMS Protective effect of alpha lipoic acid (ALA) on sciatic nerve following ischemia-reperfusion in rats was investigated by using light microscopy and biochemical methods. Provided that the protective effect o...
BACKGROUND Reperfusion aggravates nerve ischemic fiber degeneration, likely by the generation of reduced oxygen species. We therefore evaluated if racemic alpha-lipoic acid (LA), a potent antioxidant, will protect peripheral nerve from reperfusion injury, using our established model of ischemia-reperfusion injury. METHODS We used male SD rats, 300+/-5 g. Ischemia was produced by the ligature ...
Nerve ischemia, both acute and chronic, may contribute to diabetic neuropathies, but the pathogenesis remains obscure. The vulnerability of diabetic nerve to ischemia was assessed by ligating arteries of supply of rat sciatic nerve after 20 wk of streptozocin-induced diabetes. In the first 24 h after the arterial ligations, severe and more rapidly occurring clinicopathological abnormalities wer...
Edaravone has been shown to reduce ischemia/reperfusion-induced peripheral nerve injury. However, the therapeutic effect of edaravone on peripheral nerve injury caused by mechanical factors is unknown. In the present study, we established a peripheral nerve injury model by crushing the sciatic nerve using hemostatic forceps, and then administered edaravone 3 mg/kg intraperitoneally. The sciatic...
Objective(s): To investigate the systemic and local immune status of two surgical rat models of sciatic nerve injury, a crushed sciatic nerve, and a sciatic nerve transection Materials and Methods:Twenty-four adult male Sprague-Dawley rats were randomly divided into three groups: sham-operation (control group), sciatic nerve crush, and sciatic nerve transaction. Sciatic nerve surgery was perfor...
