The present study was performed to investigate the effect of trapidil on ischemic damage of cells after spinal cord injury. The injury was produced by extradural clip compression of the exposed spinal cord in rats according to Rivlin and Tator. The ten rats in group 1 were used to determine normal findings without any surgery or medication. On the 15 rats(More)
Previous studies confirm that pulsed magnetic field (PMF) accelerates functional recovery after a nerve crush lesion. The contention that PMF enhances the regeneration is still controversial, however. The influence of a new PMF application protocol (trained PMF) on nerve regeneration was studied in a model of crush injury of the sciatic nerve of rats. To(More)
Endorphins have been implicated in the pathophysiology of spinal cord injury. The effect of naloxone on the sodium- and potassium-activated and magnesium-dependent adenosine-5'-triphosphatase (Na(+)-K+/Mg+2 ATPase, EC. activity, lipid peroxidation, and early ultrastructural findings were studied in rats at the early stage of spinal cord injury,(More)
PURPOSE The purpose of the present study was to evaluate the effects of systemically administered zoledronic acid (ZA) on mandibular fracture healing in a rabbit model using radiodensitometric, biomechanical, histologic, and histomorphometric methods. MATERIALS AND METHODS A total of 36 skeletally mature male New Zealand white rabbits were used. The(More)
BACKGROUND Hypoxic-ischemic brain injury (HIBI) is a common cause of neonatal mortality and morbidity. The use of levetiracetam (LEV), as a potential neuroprotective in brain ischemia, receives an increasingly high attention, and it could have a crucial role in the regulation of epileptogenesis and neuroprotection. Potential effects of LEV on neuronal(More)
INTRODUCTION The management of acute respiratory distress syndrome (ARDS) was investigated with the use of heliox in an experimental model. OBJECTIVES To investigate whether heliox can be considered a new therapeutic approach in ARDS. METHODS ARDS was designed in Wistar albino male rats, 250-300 g in weight, by intratracheal instillation of(More)
In this study 8 patients with Alport's syndrome are presented. The ocular manifestations of these patients were retinal flecks, macular depigmentation, microspherophakia and anterior lenticonus. One patient revealed bilateral macular hole which was an unusual feature. Four patients had renal biopsies with the characteristic electron microscopic changes of(More)
We produced retrobulbar hematoma in both orbits of 10 pigs in order to assess the effects of blood elements and pressure created by the hematoma on the optic nerves. Ten other pigs were used as a control group. Following decompression in the right orbits, ocular movements, fundi, and intraocular pressure were evaluated for 6 weeks. At the end of the 6th(More)
Despite the fact that it is a frequent diabetic complication, the mechanisms underlying the manifestation of diabetic neuropathic pain remain poorly understood. In this study, we hypothesized that the depletion of peripheral macrophages with liposome-encapsulated clodronate (LEC) can prevent, at least delay, the progression of diabetes-induced neuropathic(More)
The aim of the present study was to determine the involvement of the median raphe serotonergic system in the effects of ketamine on anxiety behaviours and related memory. The effects of ketamine pretreatment (3 and 10 mg/kg, i.p.) on three types of fear-motivated behaviours, unconditioned one-way escape, conditioned avoidance and freezing were tested.(More)
