A modification of the Bennett and Xie chronic constriction injury model of peripheral painful neuropathy was developed in rats. Under tribromoethanol anesthesia, a single ligature with 100% cotton glace thread was placed around the right sciatic nerve proximal to its trifurcation. The change in the hind paw reflex threshold after mechanical stimulation observed with this modified model was comp...

Background Neuropathic pain is a complex condition characterized by sensory, cognitive and affective symptoms that magnify the perception of pain. The underlying pathogenic mechanisms are largely unknown there an urgent need for development novel medications. endocannabinoid system modulates drugs targeting cannabinoid receptor type 2 (CB2) devoid psychoactive side effects could emerge as analg...

Spinal subarachnoid hemorrhage (SSAH) is a rare condition that can cause spinal cord or nerve root compression and permanent neurologic damage. The reported etiologies include trauma, vascular malformations aneurysms, coagulopathies, neoplasms, autoimmune disease, spontaneous hemorrhage. If there evidence of deterioration, it commonly managed as surgical emergency, but cases conservative manage...

PURPOSE To develop a new rat model of postthoracotomy pain for investigating its mechanisms and clarifying neurochemical changes. METHODS Male Wistar rats were randomly assigned to three groups that underwent either fourth and fifth intercostal nerve ligation, cutting of the fourth and fifth ribs, or a sham operation in which only pleura was cut. For behavioural response assessment during the...

The development of mechanical and thermal hypersensitivity following peripheral nerve injury is well known and a great deal of research has been directed towards understanding the mechanisms underlying these phenomena. However, there has been very little research examining if hypersensitivity to an inflammatory condition following nerve injury also develops. Therefore, the purpose of the presen...

N-methyl-D-aspartate receptor (NMDAR) antagonists may be given in persistent neuropathic pain, but adverse events especially with ketamine may limit their clinical use. Less central and cognitive adverse events are described with dextromethorphan and memantine. These molecules have been explored in many preclinical and clinical studies, but data are conflicting as regards neuropathic pain allev...

Sciatic functional index (SFI) as a behavioral method was used to assess the functional recovery following experimentally-induced various injuries in the sciatic nerve, spinal cord, and brain. In the present study, the functional recovery after induction of injury in the sciatic nerve was investigated in rats using SFI. Twenty-four rats were divided into three groups including sham-operated (SS...
