background and objective: hyperalgesia is one of the marked clinical signs of patients with diabetes mellitus that affects their lifestyle. this study was conducted to assess the anti-nociceptive effect of chronic administration of curcumin in streptozotocin (stz)-diabetic rats using formalin, hot tail immersion, and paw pressure tests. materials and methods: this study was conducted on 40 male...

The objective of the present investigation was to compare the sensitivity of an electronic nociceptive mechanical paw test with classical mechanical tests to quantify the intensity variation of inflammatory nociception. The electronic pressure-meter test consists of inducing the hindpaw flexion reflex by poking the plantar region with a polypropylene pipette tip adapted to a hand-held force tra...

The aim of the present investigation was to describe and validate an electronic mechanical test for quantification of the intensity of inflammatory nociception in mice. The electronic pressure-meter test consists of inducing the animal hindpaw flexion reflex by poking the plantar region with a polypropylene pipette tip adapted to a hand-held force transducer. This method was compared to the cla...

This study investigates the antinociceptive effect of intracerebroventricular (i.c.v.) injection of cytidine-5'-diphosphate choline (CDP-choline; citicoline) and the involvement of cholinergic mechanisms in rats. Three different pain models were utilized: thermal paw withdrawal test, mechanical paw pressure test and acetic acid writhing test. The i.c.v. administration of CDP-choline (0.5, 1.0 a...

We examined the effect of several K+ channel blockers such as glibenclamide, tolbutamide, charybdotoxin (ChTX), apamin, tetraethylammonium chloride (TEA), 4-aminopyridine (4-AP), and cesium on the ability of fentanyl, a clinically used selective micro-opioid receptor agonist, to promote peripheral antinociception. Antinociception was measured by the paw pressure test in male Wistar rats weighin...

Objective: Using a non-inflammatory model of hyperalgesia, this study investigated the participation of α1 and β adrenoceptors and opioid receptor subtypes in xylazine-induced peripheral antinociception in this event. Materials & Methods: Nociceptive threshold was measured using the rat pressure test in animals that were injected with prostaglandin E2, xylazine, prazosin, propranolol, clocinnam...

BACKGROUND Rhodiola rosea (golden root) is a unique phytoadaptagen with immunomodulatory, antioxidant, anti-inflammatory and antinociceptive activity. AIM The aim of this study was to evaluate the antinociceptive and anti-inflammatory effects of the alcohol/water extract of Rhodiola rosea roots in rats. MATERIALS AND METHODS Thirty male Wistar rats were used in the study. They were divided ...

The aim of the present research was to assess in experimental and clinical study the influence of doxepin administered intraperitoneally (ip) as preemptive analgesia on the nociception in the perioperative period. The pain thresholds for mechanical stimuli were measured in rats. The objective of clinical investigation was to assess the influence of preemptive administration of doxepin on postop...
