OBJECTIVES In the present study, we investigated the potential anti-nociceptive activity and acute anti-inflammatory effect of a synthetic quinoline compound (2-(4-Methoxyphenyl)benzo[h]quinoline-4-carboxylic acid, QC), possessing structural elements of both naproxen and tomoxiprole drugs. MATERIALS AND METHODS The anti-nociceptive activity of QC was evaluated using chemical- and thermal-indu...

Study design: Case reports. Setting: University hospital setting. Objective: To analyze the effect of intravenous immunoglobulin on neuropathic and nociceptive pain in three patients with PostPolio Syndrome (PPS). Materials and Methods: Three patients with PPS and pain who received treatment with 90 g IvIg are described. Results: Before treatment one of the patients had pure neuropathic pain an...

Processing of tactile stimuli within somatosensory cortices has been shown to be complex and hierarchically organized. However, the precise organization of nociceptive processing within these cortices has remained largely unknown. We used whole-head magnetoencephalography to directly compare cortical responses to stimulation of tactile and nociceptive afferents of the dorsum of the hand in huma...

Pain and its control are still a daunting problem. Although drugs such as morphine have been around since ancient times and recent years have seen the introduction of a number of additional painkillers, many gaps remain in our ability to control the suffering of pain. Pain is an emotional response that is triggered by nociceptive inputs from the periphery that are transmitted centrally to the s...

conclusions our findings suggest that the analgesic effect of hrcle may be mediated via both peripheral and central mechanisms. the presence of flavonoids might be responsible for the anti-nociceptive activity of this plant. results hrcle significantly inhibited the number of contractions induced by acetic acid in the writhing test at all doses, while anti-nociceptive activity was only shown at ...

Following injury, nociceptive systems become sensitized, leading to heightened pain perception. The evolutionary reason for this phenomenon has been hard to pinpoint. A study in squid now suggests that nociceptive sensitization enhances survival from predators.

Abstract Anti-nociceptive activity of aerial parts of Phytolacca americana were investigated, using the hot plate method in mice. Results of the present study showed that the aqueous methanolic extract of aerial parts of P. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (P 0.05). The anti-nociceptiv...
