Diabetic neuropathic pain, an important micro vascular complication in diabetes mellitus, has been recognized as one of the most difficult types of pain to treat. Lack of understanding of etiology involved, inadequate relief, development of tolerance and potential toxicity of classical anti-nociceptive agents warrants the investigation of newer agents to relieve this pain. The aim of the presen...

fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

Electroacupuncture stimulation (EAS) is known to change brain neurotransmitter release. In the present study, we investigated the effects of synchronous or asynchronous electroacupuncture stimulation with low versus high frequency on spinal opioid release and tail flick nociception. Rats were given "2/100 Hz" EAS, which stands for an asynchronous mode of stimulation, in which 2 Hz was alternate...

The possible role of β-2 adrenergic receptors in modulation of inflammatory and nociceptive conditions suggests that the β-2 adrenergic receptor agonist, salbutamol, may have beneficial anti-inflammatory and analgesic effects. Therefore, in this study, we induced inflammatory and nociceptive responses with carrageenan-induced paw edema or cotton-pellet-induced granuloma models, both of which re...

Rationale: Cinnamoylquinides are formed from the corresponding chlorogenic acids during coffee roasting. Instant coffee has been shown to displace binding of the mu opioid receptor antagonist, [H]naloxone, but the putative active agent, feruloylquinide, has not been characterized. Objectives: The goal was to identify the active agent(s) in coffee by measuring the binding affinity of individual ...

The present study investigates the possible anti-nociceptive effect of intraperitoneal (i.p.) honokiol: a phenolic compound originally isolated from Magnolia officinalis, in acute and chronic inflammatory pain models. Doses of 0.1, 5, and 10 mg/kg honokiol were administered in carrageenan induced pain and the dose (honokiol 10 mg/kg i.p.) with most significant response among behavioral tests wa...

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...
