Effects of Acutely Applied Cannabinoid Cb1 Ligands on Nociception in Rats with a Model of Depression
The effects of CB1 receptor agonist HU-210 and cannabinoid CB1 receptor antagonist SR 141716A on nociception of male Wistar rats with a model of depression (bilateral olfactory bulbectomy, OBX) were studied. HU-210 (5 μg) and SR 141716A (3 μg) were acutely microinjected i.c.v. on the developed depression background. Nociception was examined as applied mechanical pressure on the left hind paw of...
purpose : to report a case of recurrent corneal intrastromal cyst containing lymph fluid case report : a 13-year-old girl presented with recurrent cyst of the left cornea, which had been drained three years before, but had gradually recurred. the cyst was successfully drained. histologic examination, cytologic analysis, and protein electrophoresis were performed on the cyst fluid. histopatholog...
It is generally acknowledged that humans display highly variable sensitivity to pain, including variable responses to identical injuries or pathologies. The possible contribution of genetic factors has, however, been largely overlooked. An emerging rodent literature documents the importance of genotype in mediating basal nociceptive sensitivity, in establishing a predisposition to neuropathic p...
Background and Objective: Evaluation of the results, safety, and stability of ferrara intracorneal ring segment (FICRS) implantation for Keratoconus correction (age range was 24.39±8.32 years). Materials and Methods: In this clinical trial study, 64 eyes of 57 patients with keratoconus and clear cornea that had FICRS implantation were studied. Uncorrected visual acuity (UCVA), best-spectacl...
The role of dopamine as a possible central inhibitory mediator of pain processes has been demonstrated. The administration of L-Dopa diminishes pain perception in humans as well as the response to nociceptive stimuli in animals. Also, the intracerebral microinjection of dopamine in inflammatory and neuropathic pain models (formalin test and deafferentation, respectively) reduces nociceptive res...
Identification of the brain areas that contribute to pain is an essential undertaking towards understanding persistent pain. Areas of the basal ganglia have been proposed to play important roles in nociception as previous studies have determined the involvement of the substantia nigra pars compacta and the dorsolateral striatum in pain. The purpose of the present study was therefore to expand u...
