Introduction: Peripheral nerve damage is a clinical problem that causes sensory and motor disabilities. Sesamol is an antioxidant that can be effective in repairing various organs. The aim of this study was to evaluate the effect of different doses of sesamol on inflammation and pain in the damaged rat sciatic nerve. Materials and Methods: In this study, 35 adult male Wistar rats were used. The...
BACKGROUND Tolerance to the analgesic effect of morphine complicates the management of chronic pain states. The authors studied the ability of the glycine/N-methyl-D-aspartate receptor antagonist (+)-HA966 to modify morphine tolerance in a rat model of neuropathic pain. METHODS Mononeuropathy was induced by placing four ligatures around the common sciatic nerve. The 4-day pretreatment regimen...
Fisetin, a natural flavonoid, has been shown in our previous studies to exert antidepressant-like effect. As antidepressant drugs are clinically used to treat chronic neuropathic pain, this work aimed to investigate the potential antinociceptive efficacies of fisetin against neuropathic pain and explore mechanism(s). We subjected mice to chronic constriction injury (CCI) by loosely ligating the...
The formation mechanism of TiC particles in a Ni-Ti-C system were revealed by using differential thermal analysis (DTA), XRD, and SEM to identify the reaction products in different temperature ranges. The results indicated that the synthesis mechanism of TiC in Ni-Ti-C system was complex; several reactions were involved in the combustion synthesis of TiC-Ni composite. The Ni-Ti intermediate pha...
In this paper we propose a method for evaluating test measurements for complex circuits that are difficult to simulate. The evaluation aims at estimating test metrics, such as parametric test escape and yield loss, with parts per million (ppm) accuracy. To achieve this, the method combines behavioral modeling, density estimation, and regression. The method is demonstrated for a previously propo...
this study was designed to investigate the therapeutic effects of saffron (crocus sativus l) and its main constituent crocin on neuropathic pain behavioral responses induced by chronic constriction injury (cci) in rats. adult male wistar rats (200 to 250 g) were randomly assigned into 5 groups: sham + saline, cci + saline, cci+ saffron (30 mg/kg), cci +crocin (15 mg/kg) and cci + crocin (30 mg/...
Gonadal hormones have been shown to exert modulatory effects on nociception and analgesia. To investigate the role of gonadal hormones in the response by female rats to both phasic and persistent nociceptive stimulation, we evaluated the effects of long-term ovariectomy (OVX, 6 months) on the thermal pain threshold and on formalin-induced responses. The thermal pain threshold was evaluated with...
Toluene is a major component of numerous commercial organic solvent formulations. It is often listed among the chemicals capable of producing the organic solvent syndrome and a neurobehavioral hypersensitivity condition. The hypersensitivity condition (continued long-term intensification of some behavioral reactions in response to pharmacological or environmental stressors) is usually associate...
