Background and Objective: Due to the presence of some evidence for anti-diabetic and antioxidant activity of Tribulus terrestris (TT), this study was designed to investigate the anti-nociceptive effect of TT in streptozotocin-diabetic rats using formalin test and hot tail immersion tests. Materials and Methods: Rats were divided into control, TT-treated control, diabetic, sodium salicylate (SS)...

In this study, we focused on the neuro-behavioral profile, toxicity, and ‎possible mechanisms of action of ‎ Dorema ammoniacum gum essential oil (DAG-EO). For this purpose, passive avoidance and Y-maze tests were performed to evaluate the potential effect ‎of DAG-EO in the attenuation of memory impairment induced by 49 days administration of D-‎galactose and acute injection of scopolam...

Pain is sensed by the activation of painful nociceptors in periphery or pain mediators, such as bradykinin, serotonin, histamine, and prostaglandin, released from damaged tissue, afferent transmission to medulla spinalis, transmission stages high centers over dorsal horn. Pain, which was seen only a warning sign past, now accepted phenomenon itself that needs be treated search for new, stronge...

Background: Thiamine (VitB1) is a vitamin with various important physiological functions and postulated therapeutic effects.  Its use as an analgesic in neuropathic pain has been undergoing in clinical settings. However, there has been little experimental investigation on this effect. In this study, anti-nociceptive and anti-inflammatory effects of thiamine were investigated in mice. Methods: T...

the circadian variation of the toxicity and nociceptive activity of aminophylline as an important methylxanthine was studied in mice. the animals were housed under controlled light-dark cycles for at least 2 weeks. acute toxicity was determined by ld50. hot-plate test was used for determination of thermal pain threshold. doses of 200, 250, 280 and 340 mg/kg of aminophylline were injected intrap...

In this study, 12 new 3-methyl-6-(2-substituted aminopropanoyl)-2-benzoxazolinone and 3-methyl-6-(1-hydroxy-2-substituted aminopropyl)-2-benzoxazolinone derivatives have been prepared. Their structures have been elucidated by IR, 1H NMR spectra and by elementary analysis. The anti-nociceptive activity of these compounds has been investigated by using a modified Koster test. It was found that mo...

Pain is both a sensory event of the peripheral and central nervous systems and an experience that arises from, and reciprocally can affect processes of higher consciousness. Alterations in peripheral and central neuraxes can lead to sensitization, structural modification and long-term potentiation that can overcome modulatory influence(s) and change the non-linear adaptability of these systems ...
