In the present study, the antinociceptive profiles of coumarin were examined in ICR mice. Coumarin administered orally (from 1 to 10 mg/kg) showed an antinociceptive effect in a dose-dependent manner as measured in the acetic acid-induced writhing test. Duration of antinociceptive action of coumarin maintained at least for 60 min. But, the cumulative response time of nociceptive behaviors induc...
Chemical or electrical stimulation of the dorsal portion of the midbrain periaqueductal gray (dPAG) produces anxiogenic and antinociceptive effects. In rats, chemical stimulation of dPAG by local infusion of the neuropeptide corticotropin-releasing factor (CRF) provokes anxiogenic effects in the elevated plus-maze test (EPM). CRF also produces antinociception when injected intracerebroventricul...
Murraya koenigii L. is a perennial shrub, belonging to the family Rutaceae. Traditionally, the leaves of this plant are extensively used in treatment of a wide range of diseases and disorders including pain and inflammation. Although researchers have revealed the antinociceptive effects of this plant's leaves during past few years, the mechanisms underlying these effects are still unknown. Ther...
a hydroethanolic extract (he-ext) of bacopa monnieri (bm) was studied for antinociceptive effect in the animal models of acetic-acid-induced writhing test and antilocomotive effect in mice. standard centrally-acting analgesic, morphine (mp), and peripherally-acting one, diclofenac (diclo), were also tested along with the extract for comparison. the extract exhibited significant antinociceptive ...
DALDA (H-Tyr-D-Arg-Phe-Lys-NH(2)) and [Dmt(1)]DALDA (H-Dmt-D-Arg-Phe-Lys-NH(2)) (Dmt = 2',6'-dimethyltyrosine) are potent and highly selective mu-opioid agonists (K(i)(delta)/K(i)(mu) > 10,000 and K(i)(kappa)/K(i)(mu) > 100). Both peptides carry a 3+ charge at physiological pH. Their antinociceptive and respiratory effects were compared with morphine (MOR) after intrathecal administration in ra...
The discovery that paracetamol is metabolized to the potent TRPV1 activator N-(4-hydroxyphenyl)-5Z,8Z,11Z,14Z-eicosatetraenamide (AM404) and that this metabolite contributes to paracetamol's antinociceptive effect in rodents via activation of TRPV1 in the central nervous system (CNS) has provided a potential strategy for developing novel analgesics. Here we validated this strategy by examining ...
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits anti-inflammatory, antinociceptive, and antipyretic activities. Liposomes have been shown to improve the therapeutic efficacy of encapsulated drugs. The present study was conducted to compare the antinociceptive properties between liposome-encapsulated and free-form diclofenac in vivo via different nociceptive assay model...
In neuropathic pain the repeated minocycline treatment inhibited the mRNA and protein expression of the microglial markers and metalloproteinase-9 (MMP-9). The minocycline diminished the pronociceptive (IL-6, IL-18), but not antinociceptive (IL-1alpha, IL-4, IL-10) cytokines at the spinal cord level. In vitro primary cell culture studies have shown that MMP-9, TIMP-1, IL-1beta, IL-1alpha, IL-6,...
BACKGROUND Celosia cristata Linn. (Amaranthaceae) is used in traditional medicine for the treatment of headache, sores, ulcers, eye inflammations, skin eruption, painful menstruation and carpal tunnel syndrome. This study was performed to evaluate the antinociceptive activity of methanol extract of the whole plant of C. cristata (MECC). METHODS The evaluation of the antinociceptive effect of ...
BACKGROUND Prolonged morphine treatment leads to antinociceptive tolerance. Suppression of spinal astrocytes or d-amino acid oxidase (DAAO), an astroglial enzyme catalyzing oxidation of d-amino acids, has reversed morphine antinociceptive tolerance. Since the astrocyte-DAAO pathway generates hydrogen peroxide, an agonist of the TRPA1 channel expressed spinally on nociceptive nerve terminals and...
