Abstract
The study aimed to examine the effect of intraperitoneal and intrathecal (±)-licarin A in neuropathic pain induced by L5 and L6 spinal nerve ligation (SNL) in male Wistar rats and the possible involvement of the NO-cGMP-ATP-sensitive K+ channel pathway. Neuropathic pain signs (allodynia and hyperalgesia) were evaluated on postoperative Day 14 using von Frey filaments. Single intraperitoneal (0.01, 0.1, 1, and 10 mg/kg) and intrathecal (0.01, 0.1, 1, and 10 µg/rat) administration of (±)-licarin A improved allodynia and hyperalgesia. The (±)-licarin A-induced anti-allodynic and anti-hyperalgesic activity was prevented by the intrathecal injection of l-NAME (100 µg/rat; nonselective nitric oxide synthase inhibitor), ODQ (10 µg/rat; guanylate cyclase inhibitor), and glibenclamide (50 µg/rat; adenosine triphosphate (ATP)-sensitive K+ channel blocker). The data suggest that (±)-licarin A exerts its anti-allodynic and anti-hyperalgesic activity by activating the NO-cGMP-ATP-sensitive K+ channel pathway.

Abstract
Berberine is an isoquinoline alkaloid naturally produced by several types of plants. Berberine has extensive pharmacological effects, such as anti-diabetic, anti-inflammatory, and antioxidant effects. In the current study, we assess the antinociceptive effects of berberine and its association with the l -arginine ( l -Arg)/NO/cGMP/K ATP channel pathway via intraplantar administration in rats. To examine the antinociceptive properties of berberine, the formalin test was conducted. The number of rat paw flinches was counted for an h. l -Arg (precursor of nitric oxide, 3-30 μ g/paw), l -NAME (NO synthase inhibitor, 10 and 100 μ g/paw), methylene blue (guanylyl cyclase inhibitor, 100 and 200 μ g/paw), and glibenclamide (ATP-sensitive potassium channel blocker, 10 and 30 μ g/paw) were locally injected, respectively, into the right hind paws of rats as a pre-treatment before berberine injection to understand how the l -Arg/NO/cGMP/K ATP pathway plays a role in the antinociceptive effect of berberine. The ipsilateral injection of berberine into the right paw (0.1-10 0 μ g/paw) showed a dose-dependent antinociceptive effect in both the first and second phases of the formalin test, almost similar to morphine (25 μ g/paw). Intraplantar injection of l -Arg (30 µg/paw) increased the antinociceptive effect of berberine in the second phase. In addition, injection of l -NAME, methylene blue, and glibenclamide caused a reduction in the antinociceptive effect of berberine throughout the second phase in a dose-dependent manner. However, the antinociceptive effects of berberine in the first phase of the rat formalin test were not affected by this pathway. As a novel local antinociceptive agent, berberine can exert a peripheral antinociceptive effect via the l -Arg/NO/cGMP/K ATP channel pathway.

Abstract
Rosemary essential oil (REO) has been used for several medical purposes. Previous studies have shown the antinociceptive effect of the oil. This study aimed to investigate the role of some well-known receptors in the antinociceptive effect of REO. Male Swiss mice (25-30 g) were used. To assess the antinociceptive activity, the formalin test was used. At first, the antinociceptive effect of three doses of rosemary oil (150, 300 and 450 µL/kg) was tested, and then a dose of 300 µL/kg was selected for the mechanistic study. Animals were pretreated with several antagonists and enzyme inhibitors to evaluate the role of adrenergic, cholinergic, serotoninergic, dopaminergic and opioid receptors as well as the NO/cGMP/K ATP pathway in the antinociceptive effect of rosemary essential oil. Yohimbine (5 mg/kg), prazocin (2 mg/kg), propranolol (2 mg/kg), atropine (2.5 mg/kg) naloxone (5 mg/kg), cyproheptadine (2 mg/kg), ondansetron (2 mg/kg) and haloperidol (1 mg/kg) could not reverse the antinociceptive effect. Sulpiride (20 mg/kg) only showed preventive activity in the early phase of formalin test while methylene blue (5 mg/kg), L-NAME (20 mg/kg) and glibenclamide (10 mg/kg) significantly attenuated the antinociceptive effect of REO in both phases. Tadalafil (2 mg/kg) potentiated the antinociceptive effect of REO in the late phase of formalin test and arginine (100 mg/kg) had no effect on both phases. Therefore the NO/cGMP/K ATP pathway might have an important role in the antinociceptive effect of REO.

Abstract
Chronic pain affects approximately one-fifth of people worldwide and reduces quality of life and in some cases, working ability. Ion channels expressed along nociceptive pathways affect neuronal excitability and as a result modulate pain experience. Several ion channels have been identified and investigated as potential targets for new medicines for the treatment of a variety of human diseases, including chronic pain. Voltage-gated channels Na+ and Ca2+ channels, K+ channels, transient receptor potential channels (TRP), purinergic (P2X) channels and acid-sensing ion channels (ASICs) are some examples of ion channels exhibiting altered function or expression in different chronic pain states. Pharmacological approaches are being developed to mitigate dysregulation of these channels as potential treatment options. Since natural compounds of plant origin exert promising biological and pharmacological properties and are believed to possess less adverse effects compared to synthetic drugs, they have been widely studied as treatments for chronic pain for their ability to alter the functional activity of ion channels. A literature review was conducted using Medline, Google Scholar and PubMed, resulted in listing 79 natural compounds/extracts that are reported to interact with ion channels as part of their analgesic mechanism of action. Most in vitro studies utilized electrophysiological techniques to study the effect of natural compounds on ion channels using primary cultures of dorsal root ganglia (DRG) neurons. In vivo studies concentrated on different pain models and were conducted mainly in mice and rats. Proceeding into clinical trials will require further study to develop new, potent and specific ion channel modulators of plant origin.

Abstract
Pharmacological treatment of pain often causes undesirable effects, so it is necessary to look for natural, safe, and effective alternatives to alleviate painful behavior. In this context, it is known that different parts of pomegranate have been widely consumed and used as preventive and therapeutic agents since ancient times. For example, it has been shown to have an antinociceptive effect, however, there are many varieties. Each part has been found to display unique and attractive pharmacological activities. The content of the active phytochemicals in pomegranate depends on the cultivar, geographical region, the maturity, and the processing method. In this context, the effects of various pomegranate varieties and other parts of the pomegranate (e.g., peel and juice) on pain behavior have not been examined. The aim was to evaluate and compare the antinociceptive effect of ethanolic extracts (PEx) and lyophilized juices (Lj) of three varieties of pomegranate in the formalin test. In addition, computer-aided analysis was performed for determining biological effects and toxicity. Peels were extracted with ethanol and evaporated by rotary evaporation, and juices were filtered and lyophilized. Wistar rats (N = 48) were randomly distributed into 8 groups (n = 6) (Vehicle, Acetylsalicylic Acid, PEx1, PEx2, PEx3, Lj1, Lj2, and Lj3). The formalin test (2%) was carried out, which consists of administering formalin in paw and counting the paw flinches for 1 h, with prior administration of treatments. All samples have an antinociceptive effect (phase 1: 2.8-10%; phase 2: 23.2-45.2%). PEx2 and Lj2 had the greatest antinociceptive effect (57.8-58.9%), and bioactive compounds such as tannins and flavonoids showed promising pharmacodynamic properties that may be involved in the antinociceptive effect, and can be considered as a natural alternative for the treatment of nociceptive and inflammatory pain.

Abstract
Ellagic acid (EA) is a bioactive polyphenolic compound naturally occurring as secondary metabolite in many plant taxa. EA content is considerable in pomegranate (Punica granatum L.) and in wood and bark of some tree species. Structurally, EA is a dilactone of hexahydroxydiphenic acid (HHDP), a dimeric gallic acid derivative, produced mainly by hydrolysis of ellagitannins, a widely distributed group of secondary metabolites. EA is attracting attention due to its antioxidant, anti-inflammatory, antimutagenic, and antiproliferative properties. EA displayed pharmacological effects in various in vitro and in vivo model systems. Furthermore, EA has also been well documented for its antiallergic, antiatherosclerotic, cardioprotective, hepatoprotective, nephroprotective, and neuroprotective properties. This review reports on the health-promoting effects of EA, along with possible mechanisms of its action in maintaining the health status, by summarizing the literature related to the therapeutic potential of this polyphenolic in the treatment of several human diseases.

Abstract
One of the main functions of the sensory system in our body is to maintain somatosensory homeostasis. Recent reports have led to a significant advance in our understanding of pain signaling mechanisms; however, the exact mechanisms of pain transmission have remained unclear. There is an urgent need to reveal the precise signaling mediators of pain to provide alternative therapeutic agents with more efficacy and fewer side effects. Accordingly, although the anti-inflammatory, antioxidative and anti-neuropathic effects of astaxanthin (AST) have been previously highlighted, its peripheral antinociceptive mechanisms are not fully understood. In this line, considering the engagement of l-arginine/nitric oxide (NO)/cyclic GMP (cGMP)/potassium channel (KATP) signaling pathway in the antinociceptive responses, the present study evaluated its associated role in the antinociceptive activity of AST. Male mice were intraperitoneally (i.p.) injected with l-arginine (100 mg/kg), SNAP (1 mg/kg), L-NAME (30 mg/kg), sildenafil (5 mg/kg), and glibenclamide (10 mg/kg) alone and prior to the most effective dose of AST. Following AST administration, intraplantarly (i.pl) injection of formalin was done, and pain responses were evaluated in mice during the primary (acute) and secondary (inflammatory) phases of formalin test. The results highlighted that 10 mg/kg i.p. dose of AST showed the greatest antinociceptive effect. Besides, while L-NAME and glibenclamide reduced the antinociceptive effect of AST, it was significantly increased by l-arginine, SNAP and sildenafil during both the primary and secondary phases of formalin test. These data suggest that the antinociceptive activity of AST is passing through the l-arginine/NO/cGMP/KATP pathway.

Abstract
OBJECTIVE The leukotrienes are inflammatory mediators. In the present study, the analgesic role of local montelukast, a cysteinyl leukotriene receptor antagonist, and the possible involvement of L-arginine/NO/cGMP/KATP channel pathway and PPARγ receptors was assessed in the formalin test in rats. METHODS AND RESULTS The local administration of montelukast into the hind paw produced dose-related analgesia during both phases of the formalin test. Furthermore, pre-treatment with L-NAME, methylene blue, and glibenclamide prevented montelukast (10 μg/paw)-induced antinociception in both early and late phases of the test. Moreover, the local L-arginine and diazoxide before the sub-effective dose of montelukast (3 μg/paw) produced an analgesic effect. Also, local GW-9662 blocked antinociception induced by montelukast plus pioglitazone (10 μg/paw). CONCLUSION In conclusion, montelukast produced peripheral analgesia through PPARγ receptors and activation of the L-arginine/NO/cGMP/KATP channel pathway, with potential for a new topical analgesic drug.

Abstract
Several modern drugs, which are derived from traditional herbal medicine are used in contemporary pharmacotherapy. Currently, the study of drug-plant interactions in pain has increased in recent years, looking for greater efficacy of the drug and reduce side effects. The antinociception induced by intragastric co-administration of the combination of pomegranate peel extract (PoPEx) and acetylsalicylic acid (ASA) was assessed using the isobolographic analysis in formalin test (nociceptive and inflammatory pain). The effective dose that produced 30% of antinociception (ED30) was calculated for both drugs from the logarithmic dose-response curves, subsequently generating a curve with the combination on fixed proportions (1:1) of PoPEx and ASA. Through isobolographic analysis, this experimental ED30 was compared with the calculated theoretical additive ED30. The result was a synergistic interaction, the experimental ED30 was significantly smaller (p < 0.05) than the theoretical ED30. The antinociceptive mechanism of the PoPEx-ASA combination involves the l-Arginine/NO/cGMP pathway, antioxidant capacity, and high content of total phenols. These findings suggest that an interaction between PoPEx and ASA could be a novel treatment for inflammatory and nociceptive pain, also diminish the secondary reactions of ASA.

The antinociceptive mechanisms of melatonin: role of L-arginine/nitric oxide/cyclic GMP/KATP channel signaling pathway. Behav Pharmacol 2021; 31:728-737.

Abstract
Pain is one of the most common medical challenges, reducing life quality. Despite the progression in pain management, it has remained a clinical challenge, which raises the need for investigating novel antinociceptive drugs with correspondence signaling pathways. Besides, the precise antinociceptive mechanisms of melatonin are not revealed. Accordingly, owing to the critical role of L-arginine/nitric oxide (NO)/cyclic GMP (cGMP)/KATP in the antinociceptive responses of various analgesics, the role of this signaling pathway is evaluated in the antinociceptive effects of melatonin. Male NMRI mice were intraperitoneally pretreated with the injection of L-arginine (NO precursor, 100 mg/kg), N(gamma)-nitro-L-arginine methyl ester [L-NAME, NO synthase (NOS) inhibitor, 30 mg/kg], S-nitroso-N-acetylpenicillamine (SNAP, NO donor, 1 mg/kg), sildenafil (phosphodiesterase inhibitor, 0.5 mg/kg), and glibenclamide (KATP channel blocker, 10 mg/kg) alone and before the administration of the most effective dose of melatonin amongst the intraperitoneal doses of 50, 100, and 150 mg/kg. The formalin test (2%, 25 µL, intra-plantarly) was done following the melatonin administration, then the nociceptive responses of mice were evaluated during the early phase for 5 min and the late phase for 15 min. The results showed that 100 mg/kg dose of melatonin carried out the most antinociceptive effects. While the antinociceptive effect of melatonin was increased by L-arginine, SNAP, and sildenafil, it was significantly reduced by L-NAME and glibenclamide in both phases of the formalin test, with no relation to the sedative effects of melatonin evaluated by the inclined plane test. In conclusion, the antinociceptive effect of melatonin is mediated through the L-arginine/NO/cGMP/KATP pathway.

Effect of Ellagic Acid on Seizure Threshold in Two Acute Seizure Tests in Mice. Molecules 2021; 26:molecules26164841. [PMID: 34443428 PMCID: PMC8398784 DOI: 10.3390/molecules26164841] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 08/02/2021] [Accepted: 08/04/2021] [Indexed: 01/03/2023] Open
Abstract
Ellagic acid (EA) is a natural dietary polyphenol that has many beneficial properties, including anti-inflammatory, antioxidant, antiviral, antibacterial, and neuroprotective effects. Studies have revealed that EA may modulate seizure activity in chemically induced animal models of seizures. Therefore, the aim of the present study was to investigate the effect of EA on the seizure threshold in two acute seizure tests in male mice, i.e., in the intravenous (i.v.) pentylenetetrazole (PTZ) seizure test and in the maximal electroshock seizure threshold (MEST) test. The obtained results showed that EA (100 mg/kg) significantly elevated the threshold for both the first myoclonic twitch and generalized clonic seizure in the i.v. PTZ seizure test. At the highest dose tested (200 mg/kg), EA increased the threshold for tonic hindlimb extension in the MEST test. EA did not produce any significant changes in motor coordination (assessed in the chimney test) or muscular strength (investigated in the grip-strength test). The plasma and total brain concentration-time profiles of EA after intraperitoneal and oral administration were also determined. Although further studies are necessary to confirm the anticonvulsant activity of EA, our findings suggest that it may modulate seizure susceptibility in animal models.

Abstract
Oxidative stress and the nitric oxide (NO) pathway are involved in the development of opioid analgesic tolerance and dependence. Simvastatin modulates NO and oxidative stress, so the present study aimed to investigate its effect on the development and expression of morphine analgesic tolerance and withdrawal signs in mice. Morphine tolerance and dependence were induced by twice daily morphine injection (10 mg/kg, s.c.) for 5 consecutive days. Tolerance was assessed by the hot-plate test and dependence by naloxone challenge, on the sixth day. To determine if the NO is involved in the effects of simvastatin, mice were pre-treated with l-arginine (200 mg/kg) or the NO synthesis inhibitors (L-NAME; 30 mg/kg) along with simvastatin (300 mg/kg). The results showed that acute and chronic administration of simvastatin reversed the antinociceptive tolerance of morphine and attenuated withdrawal signs in morphine-dependent mice, and this effect is reversed by l-arginine and augmented by l-NAME. Also, the concentration of NO and oxidative stress factors such as malondialdehyde content, total thiol, and glutathione peroxidase (GPx) activity in brain tissues was evaluated. Chronic administration of simvastatin reduced NO and malondialdehyde, and increased total thiol and GPx levels in the cerebral cortex and hippocampus of morphine-dependent mice which were antagonized by l-arginine, and augmented by l-NAME. In summary, simvastatin attenuates morphine-induced antinociceptive tolerance and withdrawal symptoms, at least partly, through antioxidative properties and nitric oxide pathway.

Abstract
Carbamazepine, an anticonvulsant drug, has shown antidepressant effects in clinical and experimental models. Nitric oxide (NO) is a neurotransmitter in the central nervous system and has been involved in a variety of diseases including depression. In the present study, the involvement of NO/cyclic GMP/KATP channels pathway in the antidepressant action of carbamazepine was investigated in mice. The antidepressant-like activity was assessed in the forced swim test (FST) behavioral paradigm. Carbamazepine reduced (40 mg/kg, intraperitoneal) immobility period. The antidepressant-like effect of carbamazepine (40 mg/kg, intraperitoneal) was prevented by pretreatment with L-arginine [substrate for NO synthase (NOS), 750 mg/kg, intraperitoneal], sildenafil (a PDE-5 inhibitor, 5 mg/kg, intraperitoneal) and diazoxide (K+ channels opener, 10 mg/kg). Pretreatment of mice with L-NAME (a non-selective NOS inhibitor, 10 mg/kg, intraperitoneal), methylene blue (direct inhibitor of both NOS and soluble guanylate cyclase, 10 mg/kg, intraperitoneal) and glibenclamide (an ATP-sensitive K+ channel blocker, 1 mg/kg, intraperitoneal) produced potentiation of the action of a sub-effective dose of carbamazepine (30 mg/kg, intraperitoneal). Also, carbamazepine (30 mg/kg) potentiated the antidepressant-like effect of fluoxetine through NO modulation. The various modulators used in the study did not produce any changes in locomotor activity per se. The results demonstrated that the antidepressant-like effect of carbamazepine in the FST involved an interaction with the NO/cGMP/KATP channels pathway.

Abstract
The use of complementary medicine has recently increased in an attempt to find effective alternative therapies that reduce the adverse effects of drugs. Punica granatum L. (pomegranate) has been used in traditional medicine for different kinds of pain. This review aims to explore the scientific evidence about the antinociceptive effect of pomegranate. A selection of original scientific articles that accomplished the inclusion criteria was carried out. It was found that different parts of pomegranate showed an antinociceptive effect; this effect can be due mainly by the presence of polyphenols, flavonoids, or fatty acids. It is suggested in the literature that the mechanisms of action may be related to the activation of the L-arginine / NO pathway, members of the TRP superfamily (TRPA1 or TRPV1) and the opioid system. The implications for the field are to know the mechanisms of action by which this effect is generated and thus be able to create alternative treatments for specific types of pain, which help alleviate it and reduce the adverse effects produced by drugs. The results propose that pomegranate and secondary metabolites could be considered in the treatment of inflammatory, nociceptive, and neuropathic pain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ocimum basilicum L. is a perennial herb that has been used in traditional Asian Indian medicine for thousands of years as a natural anti-inflammatory, antibiotic, diuretic, and analgesic. AIM OF THE STUDY The present study was conducted to investigate the analgesic effects of basil essential oil (BEO) in inflammatory pain models and identify underlying mechanisms. We further investigated whether BEO affects physiological pain and motor coordination. MATERIALS AND METHODS The analgesic effects of BEO were assessed in various mouse experimental pain models using formalin, acetic acid, heat, and carrageenan as stimuli. BEO was administered by intraperitoneal injection or inhalation. The involvement of various pathways in the analgesic effect of BEO was assessed by pretreating mice with selective pharmacological inhibitors, administered intraperitoneally. Opioid pathways were tested using the κ-opioid antagonist 5'-guanidinonaltrindole (GNTI; 0.3 mg/kg), δ-opioid antagonist naltrindole (NTD; 5 mg/kg) and μ-opioid antagonist naloxone (NAL; 8 mg/kg); nitric oxide (NO) pathways were tested using the NO synthase inhibitor N-nitro l-arginine methyl ester (L-NAME; 37.5 mg/kg) and NO precursor L-arginine (L-Arg; 600 mg/kg); and KATP channel pathways were tested using the ATP-sensitive K+ channel blocker, glibenclamide-hippuric acid (GHA, 2 mg/kg). Potential effects of BEO on motor coordination were assessed using a rotarod test. RESULTS BEO exerted analgesic effects in all pain models. Notably, pretreatment with naltrindole, naloxone, or L-arginine significantly reduced the analgesic effects of BEO in the formalin test. BEO increased mean withdrawal latencies in a thermal plantar test at a high dose, but not at lower doses. BEO had no effect on motor coordination. CONCLUSIONS Our findings indicate that the analgesic effects of BEO are primarily mediated by delta- and mu-opioid pathways and further suggest that BEO has potential for development as an analgesic agent for the relief of inflammatory pain.

Abstract
Objective(s): Growing evidence demonstrates that L-arginine/NO/cGMP/KATP channel pathway has a modulatory role in pain perception. Previous studies have shown that thymoquinone exerts antinociceptive effects; however, the mechanisms underlying antinociception induced by thymoquinone have not been fully clarified. The aim of the present study was to evaluate the role of L-arginine/NO/cGMP/KATP channel pathway in the central and peripheral antinociceptive effect of thymoquinone in rats. Materials and Methods: Rats were pretreated intraplantarly (IPL) or intracerebroventricularly (ICV) with L-arginine (the NO precursor), l-NAME (an NO synthase inhibitor), SNAP (an NO donor), methylene blue (a guanylyl cyclase inhibitor), glibenclamide (the blocker of KATP channel), and tetraethylammonium (TEA, a Kv channel blocker) before the injection of thymoquinone. Results: Local ipsilateral (20 and 40 μg, IPL) but not contralateral and ICV (4 and 8 μg) administration of thymoquinone caused a dose-dependent and significant antinociception in both early and late phases of the formalin test. Pretreatment of rats with L-arginine (100 μg, IPL or ICV) and SNAP (200 μg, IPL or ICV) increased while l-NAME (100 μg, IPL or 1 μg, ICV) and methylene blue (400 μg, IPL or ICV) decreased the antinociceptive effects of thymoquinone in the formalin test. The administration of TEA (IPL or ICV) did not modify but glibenclamide (50 μg, IPL or ICV) significantly abolished the peripheral and central antinociceptive effects of thymoquinone in both phases of the formalin test. Conclusion: The results of the present study indicate that L-arginine/NO/cGMP/KATP channel pathway participates in the central and peripheral antinociceptive effect of thymoquinone.

Abstract
OBJECTIVES The main purpose of this study was to assess the role of l-arginine/SNAP/NO/cGMP/KATP channel pathway in analgesic effects of α-terpineol in mice. METHODS Male NMRI mice were pretreated intraperitoneally with NO precursor (l-arginine, 100 mg/kg), NO synthase inhibitor (l-NAME, 30 mg/kg), NO donor (SNAP, 1 mg/kg), guanylyl cyclase inhibitor (methylene blue, 20 mg/kg), PDE inhibitor (sildenafil, 0.5 mg/kg), KATP channel blocker (glibenclamide, 10 mg/kg) and naloxone (2 mg/kg) 20 min before the administration of α-terpineol. The formalin test was performed 20 min after the administration of α-terpineol, and nociceptive responses of mice were recorded during 30 min. KEY FINDINGS A significant and dose-dependent antinociception was produced by α-terpineol (40 and 80 mg/kg) in both the phases of formalin test. The antinociceptive effect of α-terpineol was significantly potentiated by l-arginine in the second phase while significantly antagonized by l-NAME in both phases of formalin test. Also, SNAP and sildenafil non-significantly enhanced-while methylene blue significantly diminished-the antinociceptive effect of α-terpineol in both phases of formalin test. Glibenclamide significantly reversed the α-terpineol-induced antinociception, indicating the involvement of KATP channels in antinociceptive effect of α-terpineol. CONCLUSIONS These results indicate that the antinociceptive effect of α-terpineol is mediated through l-arginine/SNAP/NO/cGMP/KATP channel pathway.

Abstract
Mimosa tenuiflora (Willd.) Poiret, popularly known in Brazil as "jurema-preta" is widely used against bronchitis, fever, headache and inflammation. Its antioxidant, anti-inflammatory and antinociceptive potential has already been reported. To assess the orofacial antinociceptive effect of M. tenuiflora, ethanolic extracts of M. tenuiflora (leaves, twigs, barks and roots) were submitted to in vitro tests of antioxidant activity. The extract with the highest antioxidant potential was partitioned and subjected to preliminary chemical prospecting, GC-MS, measurement of phenolic content and cytotoxicity tests of the fraction with the highest antioxidant activity. The nontoxic fraction with the highest antioxidant activity (FATEM) was subjected to tests of acute and chronic orofacial nociception and locomotor activity. The possible mechanisms of neuromodulation were also assessed. The EtOAc fraction, obtained from the ethanolic extract of M. tenuiflora barks, was the one with the highest antioxidant potential and nontoxic (FATEM), and Benzyloxyamine was the major constituent (34.27%). FATEM did not alter the locomotor system of mice and reduced significantly the orofacial nociceptive behavior induced by formalin, glutamate, capsaicin, cinnamaldehyde or acidic saline compared to the control group. FATEM also inhibited formalin- or mustard oil-induced temporomandibular nociception. In addition, it also reduced mustard oil-induced orofacial muscle nociception. However, FATEM did not alter hypertonic saline-induced corneal nociception. Neuropathic nociception was reversed by treatment with FATEM. The antinociceptive effect of FATEM was inhibited by naloxone, L-NAME and glibenclamide. FATEM has pharmacological potential for the treatment of acute and neuropathic orofacial pain and this effect is modulated by the opioid system, nitric oxide and ATP-sensitive potassium channels. These results lead us to studies of isolation and characterization of bioactive principles.

Abstract
The present study was conducted to evaluate the local antinociceptive actions of fluoxetine, a selective serotonin reuptake inhibitor, and the possible involvement of the l-arginine/NO/cGMP/KATP channel pathway in this effect using the formalin test in rats. To elucidate the underlying mechanisms, animals were pre-treated with l-NAME, aminoguanidine, methylene blue, glibenclamide, l-arginine, sodium nitroprusside, or diazoxide. Local ipsilateral, but not contralateral, administration of fluoxetine (10-300 μg/paw) dose-dependently suppressed flinching number during both early and late phases of the test, and this was comparable with morphine also given peripherally. Pre-treatment with l-NAME, aminoguanidine, methylene blue, or glibenclamide dose-dependently prevented fluoxetine (100 μg/paw)-induced antinociception in the late phase. In contrast, administration of l-arginine, sodium nitroprusside, and diazoxide significantly enhanced the antinociception caused by fluoxetine in the late phase of the test. However, these treatments had no significant effect on the antinociceptive response of fluoxetine in the early phase of the formalin test. Our data demonstrate that local peripheral antinociception of fluoxetine during the late phase of the formalin test could be due to activation of l-arginine/NO/cGMP/KATP channel pathway. The peripheral action of fluoxetine raises the possibility that topical application of this drug (e.g., as a cream, ointment, or jelly) may be a useful method for relieving the inflammatory pain states.

Abstract
BACKGROUND Endothelial outgrowth cells (EOCs) are terminal endothelial progenitor cells (EPCs). Asymmetric dimethylarginine (ADMA) has been identified as a novel risk factor for cardiovascular diseases. Our aim in the present study was to investigate the effect of regulation of asymmetric dimethylarginine (ADMA) on EOCs apoptosis and to explore the underlining mechanisms of c-Jun N-terminal protein kinase (JNK) pathway in the process. MATERIAL AND METHODS EOCs were harvested from umbilical cord blood and obtained by using density gradient centrifugation and adhesive culture methods. Endothelial characteristics were identified by immunohistochemistry and fluorescence staining. EOCs were treated with different concentrations of ADMA and detected by flow cytometry. After JNK specific inhibitor (SP600125) was added, EOCs apoptosis protein expressions were measured by Western blot analysis. Proliferation, migration, and vascularization were detected by CCK-8 assay, wound healing assay, and tube-like formation assay, respectively. RESULTS EOCs were successfully extracted from umbilical cord blood and different concentrations of ADMA aggravated EOCs apoptosis. ADMA distinctly activates the phosphorylation activity of JNK. Supplementation of JNK-specific inhibitor (SP600125) decreased expression of Bax and cleaved caspase 3/9, and alleviated ADMA-induced apoptosis. SP600125 also promoted angiogenesis viability. CONCLUSIONS The JNK pathway participates in the apoptosis-promoting process of EOCs, and targeted inhibition of the JNK pathway can alleviate ADMA-induced injury, which I s the potential underlying mechanism of vascular endothelium injury in ischemic stroke.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leaves and stems bark of Memora nodosa (Silva Manso) Miers (Bignoniaceae) are used in Brazilian traditional medicine in the treatment of external ulcers and wounds; its roots are used to treat abdominal pain and scabies. AIM OF THE STUDY Our aim was to evaluate the antinociceptive and anti-inflammatory activities of Memora nodosa roots ethanolic extract (EMN) and allantoin, a secondary metabolite isolated from this plant. MATERIALS AND METHODS The EMN and allantoin antinociceptive activity were evaluated in mice using both chemical and heat-induced pain models such as acetic acid-induced writhing, formalin and tail-flick tests. In the formalin test, a pre-treatment with naloxone was used to verify an involvement of opioid receptor in the antinociceptive effect of EMN and allantoin. Pre-treatment with glibenclemide was used to verity an involvement of ATP-sensitive K(+)channel in the allantoin antinociceptive effect. EMN and allantoin anti-inflammatory activity were assessed by carrageenan-induced paw edema and pleurisy tests. RESULTS The treatment with EMN (250, 500 and 1000mg/kg, p.o.) inhibit the acetic acid and formalin (both phases)-induced nociception. However, just at doses 500 and 1000mg/kg increased the latency time in tail-flick test. These results suggest the involvement of both peripheral and central antinociceptive mechanisms. The treatment with allantoin (40, 60 and 80mg/kg p.o.) produced a dose-dependent antinociceptive effect in both phases of formalin-induced nociception test; allantoin (60mg/kg) was not able to increase the latency time in tail flick-test. The pre-treatment with naloxone completely reversed the EMN (1000mg/kg) and allantoin (60mg/kg) effect in the first phase of formalin test; and glibenclamide reversed the allantoin effect. The administration of EMN (250, 500 and 1000mg/kg) and allantoin (60mg/kg) showed significant anti-inflammatory activity in the whole carrageenan-induced paw edema. Furthermore, EMN and allantoin reduced the leukocytes migration and pleural exudate to the pleural cavity. CONCLUSION EMN have significant antinociceptive and anti-inflammatory effects, which appear to be, at least in part, due to the presence of allantoin. However, allantoin is not responsible for the EMN central antinociceptive activity. Allantoin has peripheral antinociceptive activity that involves the opioid receptor and ATP-sensitive K(+)channels. Opioid receptors are also involved in the EMN antinociceptive activity. These findings support the use of Memora nodosa in popular medicine and demonstrate that this plant has therapeutic potential for the development of antinociceptive and anti-inflammatory phytomedicines.

Abstract
CONTEXT Ellagic acid (EA) produced antinociceptive and anti-inflammatory effects through the central and peripheral sites of action. OBJECTIVE The objective of the current study was to examine the functional interaction between ellagic acid and carbamazepine (CBZ) on pain. MATERIALS AND METHODS Fourteen groups of mice (8-10 each) were used in this study. Pain was induced by intraperitoneal acetic acid in mice (writhing test) and the functional interaction was analyzed using the isobolographic method. EA at doses 0.3, 1, 3, and 10 mg/kg and carbamazepine at doses 3, 10, 20, and 30 mg/kg, alone and also in combination (1/2, 1/4, and 1/8 of the drug's ED50) were intraperitoneally administered 30 min before acetic acid (0.6% v/v). Then, the abdominal writhes were counted during a 25-min period. RESULTS EA (0.3-10 mg/kg, i.p.) and CBZ (3-30 mg/kg, i.p.) inhibited the writhing response evoked by acetic acid. Fifty percent effective dose (ED50) values against this tonic pain were 1.02 mg/kg and 6.40 mg/kg for EA and CBZ, respectively. The antinociception induced by EA showed higher potency than that of carbamazepine. Co-administration of increasing fractional increments of ED50 values of EA and CBZ produced additive interaction against writhing responses, as revealed by isobolographic analysis. DISCUSSION AND CONCLUSION These results suggest that a combination of carbamazepine and ellagic acid may be a new strategy for the management of neuropathic pain such as what occurs in trigeminal neuralgia, since the use of carbamazepine is often limited by its adverse effects and by reduction of its analgesic effect through microsomal enzyme induction.
