Abstract
BACKGROUND Occupational therapy (OT) has historically used cooking as an intervention and assessment approach across settings. Current practices in OT and the emergence of the multidisciplinary field of culinary medicine highlight the relationship between cooking and health. AIMS/OBJECTIVES To map the current literature on OT and cooking and to identify key factors that may facilitate collaboration within culinary medicine. MATERIALS AND METHODS We conducted a scoping review using the Joanna Briggs Institute methodology to identify primary contexts and clinical settings. Publications were analysed using framework thematic analysis to identify OT themes and roles. RESULTS A total of 56 studies met the criteria for inclusion. The majority of studies (n = 29, 53%) represented home/community settings and brain injury was the largest clinical group (n = 15, 27%). Primary themes related to person (n = 47, 43%), occupation (n = 30 (28%), environment (n = 19, 17%), and psychosocial wellbeing (n = 13, 12%). The primary OT role identified was that of interventionist (n = 48, 86%). CONCLUSIONS/SIGNIFICANCE OT's holistic practice places cooking within a larger context that can help identify and overcome the barriers to participation. Findings support multiple pathways in which OT can contribute to cooking initiatives for health promotion and potentially expand OT practice in population health.

Abstract
OBJECTIVE Non-Alcoholic fatty liver disease (NAFLD) is becoming the most common liver disease in Western populations. While obesity and metabolic abnormalities are highly frequent in bipolar disorders (BD), no studies have been performed to estimate the prevalence of NALFD in individuals with BD. The aim of our study is to estimate the prevalence of NAFLD and to identify the potential associated risk factors in a large sample of BD individuals. METHODS Between 2009 and 2019, 1969 BD individuals from the FACE-BD cohort were included. Individuals with liver diseases, Hepatitis B or C, and current alcohol use disorders were excluded from the analyses. A blood sample was drawn from participants. Screening of NAFLD was determined using fatty liver index (FLI). Individuals with FLI> 60 were considered as having NAFLD. RESULTS The prevalence of NAFDL in this sample was estimated at 28.4%. NAFLD was observed in 40% of men and 21% of women. NAFLD was independently associated with older age, male gender, sleep disturbances, and current use of atypical antipsychotics or anxiolytics. As expected, the prevalence of NALFD was also higher in individuals with overweight and in those with metabolic syndrome. CONCLUSIONS This study reinforces the view that individuals with BD are highly vulnerable to metabolic and cardiovascular diseases. The prevalence of NAFLD in individuals with BD was two times higher than the prevalence reported in the general population. The regular screening of the MetS in individuals with BD should be therefore complemented by the additional screening of NAFLD among these vulnerable individuals.

Abstract
OBJECTIVE We aimed at identifying distinct trajectories of functioning and at describing their respective clinical characteristics in a cohort of individuals with bipolar disorders. METHODS We included a sample of 2351 individuals with bipolar disorders who have been followed-up to 3 years as part as the FondaMental Advanced Centers of Expertise in Bipolar Disorders cohort. Global functioning was measured using the Functioning Assessment Short Test. We used latent class mixed models to identify distinct longitudinal trajectories of functioning over 3 years. Multivariable logistic regression models were used to identify the baseline factors that were associated with the membership to each trajectory of functioning. RESULTS Three distinct trajectories of functioning were identified: (1) a majority of individuals (72%) had a stable trajectory of mild functional impairment, (2) 20% of individuals had a stable trajectory of severe functional impairment and (3) 8% of individuals had a trajectory of moderate functional impairment that improved over time. The membership to a trajectory of stable severe versus stable mild functional impairment was associated with unemployment, a higher number of previous hospitalizations, childhood maltreatment, a higher level of residual depressive symptoms, higher sleep disturbances, a higher body mass index and a higher number of psychotropic medications being prescribed at baseline. The model that included these seven factors led to an area under the curve of 0.85. CONCLUSION This study enabled to stratify individuals with bipolar disorders according to three distinct trajectories of functioning. The results regarding the potential determinants of the trajectory of severe functional impairment needs to be replicated in independent samples. Nevertheless, these potential determinants may represent possible therapeutic targets to improve the prognosis of those patients at risk of persistent poor functioning.

Abstract
PURPOSE The objective of the PERSAT study was to evaluate first-line treatment of BPH-associated LUTS in real-life conditions. METHODS This prospective observational study was conducted in France by general practitioners (GP) on patients with moderate to severe LUTS (IPSS ≥12). GPs freely decided to prescribe either an alpha-blocker (AB) or phytotherapeutic treatment (PT). The main criterion was the percentage of responding patients (decrease in total IPSS score ≥3) at 6 months. RESULTS Of the 849 patients included, 759 were analysed (381 treated with AB and 378 with PT); 718 were followed up at 6 months, 90% of which had no treatment modification. Their inclusion characteristics were similar between the AB and PT groups (mean IPSS: 18.6±4.5 and 17.8±4.1, respectively). Treatment response rates at 6 months were 94.2% [91.2%; 96.4%] in AB and 92.5% [89.2%; 95.1%] in PT. The IPSS decreased by 10.0±5.6 points, with no difference between groups. The proportion of patients bothered by their LUTS (IPSS-QoL ≥4) evolved from 88.5% to 6.5% at 6 months. The improvement of LUTS was perceived by more than 94% of patients (PGI-I) and doctors (CGI-I), 93% of patients were satisfied with the treatment at 6 months, regardless of the treatment initiated. The most reported adverse reactions were ejaculation disorder (3.9% for AB and 0.9% for PT). CONCLUSION PERSAT confirms in current practice the effectiveness of AB and PT treatments, recommended as first-line treatment in LUTS/BPH. LEVEL OF PROOF 3.

Abstract
OBJECTIVE This study aimed to evaluate the immediate effects of medial arch supports on indices of medial knee joint load (the peak external knee adduction moment (KAM) and knee adduction angular (KAA) impulse) and knee pain during walking in people with medial knee osteoarthritis (OA). DESIGN Twenty-one people with medial compartment OA underwent gait analysis in standardised athletic shoes wearing (1) no medial arch supports and (2) prefabricated medial arch supports, in random order. Outcomes were the first and second peaks in the external KAM, the KAA impulse and severity of knee pain during testing. Outcomes were compared across conditions using paired t tests (gait data) and Wilcoxon Signed Ranks test (pain data). RESULTS There were no significant changes in either first or second peak KAM, or in the KAA impulse, with the addition of medial arch supports (all P > 0.05). Considerable individual variation in response to the arch supports was observed across participants. There was no immediate change in knee pain during walking when medial arch supports were worn (P = 0.56). CONCLUSIONS This study showed no mean change in any of the measured indices of medial knee load with medial arch supports. No immediate changes in knee pain were evident.

Abstract
BACKGROUND AND PURPOSE Xaliproden (SR57746A) is a 5-HT(1A) receptor agonist and neurotrophic agent that reduces oxaliplatin-mediated neuropathy in clinical trials. The present study investigated its profile on in vitro transduction, neurochemical responses and acute nociceptive pain tests in rats. EXPERIMENTAL APPROACH Xaliproden was tested on models associated with 5-HT(1A) receptor activation including G-protein activation, extracellular dopamine and 5-HT levels measured by microdialysis and formalin-induced pain. Activation of 5-HT(1A) receptors was confirmed by antagonism with WAY100635. KEY RESULTS Xaliproden exhibited high affinity for rat (r) and human (h) 5-HT(1A) receptors (pK(i)= 8.84 and 9.00). In [(35)S]GTPgammaS (guanosine 5'-O-(3-[(35)S]thio)triphosphate) assays it activated both hippocampal r5-HT(1A)[pEC(50)/E(MAX) of 7.58/61% (%5-HT)] and recombinant h5-HT(1A) receptors (glioma C6-h5-HT(1A): 7.39/62%; HeLa-h5-HT(1A): 7.24/93%). In functional [(35)S]GTPgammaS autoradiography, xaliproden induced labelling in structures enriched with 5-HT(1A) receptors (hippocampus, lateral septum, prefrontal and entorhinal cortices). Xaliproden inhibited in vivo binding of [(3)H]WAY100635 to 5-HT(1A) receptors in mouse frontal cortex and hippocampus (ID(50): 3.5 and 3.3 mg x kg(-1), p.o. respectively). In rat, it increased extracellular dopamine levels in frontal cortex and reduced hippocampal 5-HT levels (ED(50): 1.2 and 0.7 mg x kg(-1), i.p. respectively). In a rat pain model, xaliproden inhibited paw licking and elevation (ED(50): 1 and 3 mg x kg(-1), i.p. respectively) following formalin injection in the paw. All effects were reversed by pretreatment with WAY100635. CONCLUSIONS AND IMPLICATIONS These results indicate that activation of 5-HT(1A) receptors is the principal mechanism of action of xaliproden and provide further support for the utility of 5-HT(1A) receptor activation as an anti-nociceptive strategy.

Abstract
BACKGROUND AND PURPOSE The D(2)/D(3) receptor antagonist, D(4) receptor partial agonist, and high efficacy 5-HT(1A) receptor agonist F15063 was shown to be highly efficacious and potent in rodent models of activity against positive symptoms of schizophrenia. However F15063 induced neither catalepsy nor the 'serotonin syndrome'. Here, we evaluated its profile in rat models predictive of efficacy against negative symptoms/cognitive deficits of schizophrenia. EXPERIMENTAL APPROACH F15063, given i.p., was assessed in models of behavioural deficits induced by interference with the NMDA/glutamatergic (phencyclidine: PCP) or cholinergic (scopolamine) systems. KEY RESULTS Through 5-HT(1A) activation, F15063 partially alleviated (MED: 0.04 mg kg(-1)) PCP-induced social interaction deficit between two adult rats, without effect by itself, underlining its potential to combat negative symptoms. At doses above 0.16 mg kg(-1), F15063 reduced interaction by itself. F15063 (0.16 mg kg(-1)) selectively re-established PCP-impaired 'cognitive flexibility' in a reversal learning task, suggesting potential against adaptability deficits. F15063 (0.04-0.63 mg kg(-1)) also reversed scopolamine-induced amnesia in a juvenile-adult rat social recognition test, indicative of a pro-cholinergic influence. Activity in this latter test is consistent with its D(4) partial agonism, as it was blocked by the D(4) antagonist L745,870. Finally, F15063 up to 40 mg kg(-1) did not disrupt basal prepulse inhibition of startle reflex in rats, a marker of sensorimotor gating. CONCLUSIONS AND IMPLICATIONS The balance of D(2)/D(3), D(4) and 5-HT(1A) receptor interactions of F15063 yields a promising profile of activity in models of cognitive deficits and negative symptoms of schizophrenia.

Abstract
BACKGROUND AND PURPOSE F15063 is a high affinity D(2)/D(3) antagonist, D(4) partial agonist, and high efficacy 5-HT(1A) agonist, with little affinity (40-fold lower than for D(2) receptors) at other central targets. Here, the profile of F15063 was evaluated in models of positive symptoms of schizophrenia and motor side-effects. EXPERIMENTAL APPROACH Rodent behavioural tests were based on reversal of hyperactivity induced by psychostimulants and on measures of induction of catalepsy and 'serotonin syndrome'. KEY RESULTS F15063 potently (ED(50)s: 0.23 to 1.10 mg kg(-1) i.p.) reversed methylphenidate-induced stereotyped behaviors, blocked d-amphetamine and ketamine hyperlocomotion, attenuated apomorphine-induced prepulse inhibition (PPI) deficits, and was active in the conditioned avoidance test. In mice, it reversed apomorphine-induced climbing (ED(50)=0.30 mg kg(-1) i.p.). F15063, owing to its 5-HT(1A) agonism, did not produce (ED(50)>40 mg kg(-1) i.p.) catalepsy in rats and mice, a behavior predictive of occurrence of extra-pyramidal syndrome (EPS) in man. This absence of cataleptogenic activity was maintained upon sub-chronic treatment of rats for 5 days at 40 mg kg(-1) p.o. Furthermore, F15063 did not induce the 'serotonin syndrome' in rats (flat body posture and forepaw treading: ED(50) >32 mg kg(-1) i.p.). CONCLUSIONS AND IMPLICATIONS F15063 conformed to the profile of an atypical antipsychotic, with potent actions in models of hyperdopaminergic activity but without inducing catalepsy. These data suggest that F15063 may display potent antipsychotic actions with low EPS liability. This profile is complemented by a favourable profile in rodent models of negative symptoms and cognitive deficits of schizophrenia (companion paper).

Abstract
Purpose: To develop a conceptual model for patients withmusculoskeletal injuries that relates Injury Screening to Measurement and Monitoring (ISMAM). Screening scores would predict quantifiable outcomes on a proposed Global Assessment of Body And Limbs (GABAL) composite scale. The scale would define status as a percentage of pre-injury capacity using quantitative and qualitative self report outcome measures combined with work and life status data. Background: Screening questionnaires use psychosocial yellow flags and activity limitation to identify potential chronic patients. Outcome measures provide clinical evidence by establishing patient status and assessing intervening change. Independently developed,definitive statistical links between these established concepts are yet to be determined. Description: The ISMAM components are integrated using a graph of time versus score on the GABAL-scale with initial screening predicting recovery time to a designated pre-injury percentage level. Actual status would be assessed through initial then subsequent sequential measurements with GABAL-scale scores enabling trendline analysis to verify if the rate of actual recovery coincides with that predicted by screening. Observations: Face and content validity are apparent because validated screening tools are available and the requiredcomponents for the GABAL-scale would be existing validated outcome measures and quantifiable data.Conclusions: This model should provide a practical method of integrating screening and global measurement thatfacilitates communication across agencies and professions. A clinical research trial to validate the ISMAM concepthas been initiated.

Abstract
Previously, we have reported that in rat models of chronic pain, in particular, the very-high-efficacy 5-HT(1A) agonist F 13640 induces unprecedented pain relief by novel neuroadaptative mechanisms that involve inverse tolerance and cooperation with nociceptive stimulation in producing analgesia. The present studies detailed the actions of F 13640 and other compounds in the formalin model of tonic nociceptive pain. Intraperitoneal injection of F 13640 (0.01-2.5 mg/kg; t -15 min) caused a dose-dependent and complete inhibition of the paw elevation and paw licking that occurred both early (0-5 min) and late (22.5-27.5 min) after the intraplantar injection of diluted formaldehyde (2.5%) in the rat. The extent to which F 13640 and other 5-HT(1A) receptor ligands inhibited these pain behaviors correlated (p < 0.05) with the extent to which they activated 5-HT(1A) receptors. Under similar conditions, some inhibitory effects were also observed with various agents that are known to produce analgesia by different peripheral and/or central mechanisms (e.g., opioids, NA/5-HT reuptake inhibitors, COX-2 inhibitors and other nonsteroidal anti-inflammatory drugs, gabapentin, and ABT-594). However, with the possible exception of morphine, the effects of all of these agents at nontoxic doses were lower than those of F 13640, in particular in inhibition of early paw elevation. The 5-HT(1A) antagonist WAY 100635, but not naloxone, antagonized the actions of F 13640. These results help to establish large-magnitude 5-HT(1A) receptor activation as a new molecular mechanism of profound, central analgesia and suggest that F 13640 may be particularly effective against pain arising from severe tonic nociceptive stimulation.

Abstract
We report the discovery of F 13640 and evidence suggesting this agent to produce powerful, broad-spectrum analgesia by novel molecular and neuroadaptative mechanisms. F 13640 stimulates G(alphaomicron) protein coupling to 5-HT(1A) receptors to an extent unprecedented by selective, non-native 5-HT(1A) ligands. Fifteen minutes after its injection in normal rats, F 13640 (0.01-2.5 mg/kg) decreases the vocalization threshold to paw pressure; 15 min upon injection in rats that are exposed to formalin-induced tonic nociception, F 13640 inhibits pain behavior. The initial hyperalgesia induced by 0.63 mg/kg F 13640 was followed, 8 hrs later, by paradoxical hypo-algesia; 5 mg/kg of morphine produces the opposite effects (i.e., hypo-algesia followed by hyper-algesia). Repeated F 13640 injections cause an increase in the basal vocalization threshold and a reduction of F 13640-produced hyperalgesia; in these conditions, morphine causes basal hyperalgesia and antinociceptive tolerance. Continuous two-week infusion of F 13640 (0.63 mg/day) exerts little effect on the threshold in normal rats, but markedly reduces analgesic self-administration in arthritic rats. F 13640 infusion also decreases allodynic responses to tactile and thermal stimulations in rats sustaining spinal cord or sciatic nerve injury. In these models of chronic nociceptive and neuropathic pain, the analgesia afforded by F 13640 consistently surpasses that of morphine (5 mg/day), imipramine (2.5 mg/day), ketamine (20 mg/day) and gabapentin (10 mg/day). Very-high-efficacy 5-HT(1A) receptor activation constitutes a novel mechanism of central analgesia that grows rather than decays with chronicity, that is amplified by nociceptive stimulation, and that may uniquely relieve persistent nociceptive and neuropathic pains.

Abstract
The present study was designed to investigate which subtype of spinal 5-HT receptors were involved in acetaminophen-induced antinociception using the paw-pressure test. Propacetamol (prodrug of acetaminophen, 400 mg/kg, injected intravenously, corresponding to 200 mg/kg of acetaminophen) produced a significant antinociceptive effect in this test. This effect was at least partially inhibited by intrathecal (i.t.) pretreatment with the 5-HT(1B) (penbutolol), 5-HT(2A) (ketanserin), 5-HT(2C) (mesulergine) receptor antagonists, but not by the 5-HT(1A) (N-[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]-N-(2-pyridinyl)cyclohexanecarboxamide trihydrochloride, WAY 100635) and 5-HT(3) (granisetron) receptor antagonists. This profile was very close to that obtained recently with 5-HT, which suggests an implication of 5-HT in the spinal antinociceptive effect of acetaminophen. These results, the lack of binding of acetaminophen to 5-HT receptors and the increase of central 5-HT levels induced by this drug suggest that acetaminophen-induced antinociception could be indirectly mediated by 5-HT.

Abstract
The experiments examined antinociceptive and intrinsic behavioral effects induced by the prototypical 5-HT1A receptor agonist 8-OH-DPAT (8-hydroxy-2-[di-n-propylamino] tetralin) in rats. 8-OH-DPAT (0.01-2.5 mg/kg, subcutaneous (s.c.)) reduced both the paw licking and paw elevation induced by (2.5%) formalin injection into the plantar surface of the right hindpaw; it also produced forepaw treading. All of these effects were completely blocked by pretreatment with WAY 100635 (N-(2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl)-N-(2-pyridinyl) cyclohexanecarboxamide trihydrochloride) (0.16 mg/kg, s.c.); prazosin (0.63 mg/kg, s.c.) inhibited forepaw treading, but not 8-OH-DPAT's action on paw elevation and paw licking. Repeated injection of 8-OH-DPAT (0.63 mg/kg, s.c.) twice daily for 4 days, markedly reduced 8-OH-DPAT's ability to produce forepaw treading, but exerted only little and inconsistent effects on its paw licking and paw elevation-inhibiting action. The data indicate that 8-OH-DPAT exerts an analgesic action in the formalin model of tonic nociceptive pain; this action is mediated by 5-HT(1A) receptors, and is not confounded by the productive sign (i.e., forepaw treading) of the 5-HT syndrome which 8-OH-DPAT also induces.

Abstract
The present study examined the effects of intrathecal (i.t.) administration of 5-hydroxytryptamine (5-HT; 0.1-100 microg) on mechanical hyperalgesia associated with neuropathic pain (chronic constriction of the sciatic nerve model and diabetic model) and inflammatory pain (carrageenan and polyarthritic models) in rats. Results demonstrated that the hyperalgesia observed in the mononeuropathic and diabetic rats was attenuated by 5-HT; the active dose, however, was 100- to 1000-fold higher than that required in normal rats, and was moderately effective. In the two experimental models of inflammatory pain, 5-HT was not markedly or similarly active. In the carrageenan model, 5-HT at the highest dose was only weakly effective whereas in the polyarthritic model it was inactive. Together, these results show that 5-HT has antinociceptive effects in several rat pain models, except in the model of diffuse pain (polyarthritic rats). Its antinociceptive effects in these models, however, are slight and differ from those observed in normal rats.

Abstract
The effect of a commonly used experimental pain-induction procedure (formalin injection into a hindpaw site) on morphine tolerance, withdrawal, and reward was examined in rats. Results suggest that the effects of morphine are different in the organism that is experiencing pain at the time it receives the drug than in the organism that is pain free. The presence of pain at the time of each morphine administration decreased analgesic tolerance, decreased naloxone-precipitated withdrawal, and enhanced the rewarding effect of the opiate. These findings, together with those of previous studies, suggest that theories of opiate tolerance, withdrawal, and reward should incorporate the effects of pain.

Abstract
The present study was designed to investigate which subtypes of spinal 5-HT receptors are involved in 5-HT-induced antinociception using the mechanical pain test. Serotonin and various selective antagonists or agonists for 5-HT receptor subtypes (5-HT(1A), 5-HT(1B), 5-HT(2A), 5-HT(2C), 5-HT(3) and 5-HT(4)) were administered intrathecally (i.t.) in rats. The i.t. injection of 5-HT (1 microg) produced significant antinociceptive effects using the paw pressure test. Pretreatment with the 5-HT(2C) receptor antagonist mesulergine (1 and 10 microg) and the 5-HT(3) receptor antagonist tropisetron (1 and 10 microg) reversed totally the antinociception induced by 5-HT. Furthermore, at a dose of 10 microg, both the 5-HT(2A) receptor antagonist ketanserin and the 5-HT(1B) receptor antagonist penbutolol, but neither the 5-HT(1A) receptor antagonist WAY 100635 nor the 5-HT(4) receptor antagonist GR113808, attenuated the antinociceptive effect induced by 5-HT. In addition, an i.t. injection of the 5-HT(3) agonist mCPBG induced significant antinociceptive effects whereas the 5-HT(2) agonist DOI did not produce analgesia. These results suggest that although the precise degree of the involvement of spinal serotonergic 5-HT(3) receptors remains to be elucidated due to some differences in the effect of agonists or antagonists, these receptors seem to play a role in the antinociceptive effect of 5-HT against a mechanical acute noxious stimulus. The involvement of 5-HT(2C) is more questionable due to the observed discrepancies between the effects of the used agonist and antagonist. 5-HT(1A) and 5-HT(4) receptors do not seem to be involved. In addition, a possible functional interaction between spinal serotonergic receptors may exist.

Abstract
We tested the antinociceptive effect of intrathecal (i.t.) administration of 5-HT3 and the 5-HT3 receptor agonist, 1-(m-chlorophenyl)-biguanide (mCPBG), in rats submitted to a mechanical noxious stimulus and the influence of the 5-HT3 receptor selective antagonists, tropisetron and granisetron. Both 5-HT and mCPBG (0.01, 0.1, 1, 10, 20 micrograms/rat) produced a significant dose-dependent antinociception. The lowest active doses were 0.1 and 1 microgram for 5-HT and mCPBG, respectively. The effect, observed with 20 micrograms, was significantly lower with mCPBG (+33 +/- 6%) than with 5-HT (+63 +/- 7%). For 5-HT-induced antinociception, the minimal inhibitory doses were 0.001 micrograms/rat for tropisetron and 10 micrograms/rat for granisetron. In contrast, the same doses of the two antagonists (from 0.1 microgram/rat) similarly inhibited the effect of mCPBG. This study provides evidence that contrary to tropisetron, doses of granisetron able to inhibit the effect of a 5-HT3 receptor agonist failed to reduce that of 5-HT. This demonstrates a heterogeneity between 5-HT3 receptor antagonists and questions the true involvement of these receptors in spinal 5-HT-induced antinociception.

Abstract
The formalin test is a valuable tool widely used in animal pain studies. We offer a new automated technique based on continuous recording of movements of animals injected in a hindpaw with formalin (5%). This method, based on image processing, allows the discrimination of specific pain-induced behaviors and general motor activity. The comparison of the pain scores evaluated by manual and automated methods showed the same biphasic response. This new process was validated by using compounds known to alter pain responses to formalin: morphine and a non-steroidal anti-inflammatory drug (ketoprofen). Morphine dose-dependently usually affects the two phases of formalin response with ED50 of 2.0 +/- 0.5 and 1.5 +/- 0.5 mg/kg s.c. for the first and the second phase, respectively. The injection of ketoprofen significantly decreased pain scores of the second phase but not those of the first phase. The specificity of the method was studied by determining the effect of diazepam. This sedative compound induced a decrease in pain scores as well as a decrease in motor activity parameters. These data show that this automated technique can be considered as a relevant, sensitive and specific tool which allows the easier use of the formalin test especially for the screening of analgesic drugs.

Abstract
The aim of this study was to determine the changes of the nociceptive thresholds in response to an acute mechanical stimulus (paw pressure) in magnesium (Mg)-deficient rats, and the involvement of the NMDA receptor in these changes. Changes in vocalization thresholds was determined after 7 days of feeding with a Mg-depleted diet. Compared with the control group, Mg-deficient rats showed a significant decrease in the vocalization thresholds (-35.8 +/- 2.5%, p < 0.001) reflecting hyperalgesia. In Mg-deprived rats, three doses (0.06, 0.12 and 0.24 mg/kg s.c.) of dizocilpine (MK801), a non-competitive NMDA receptor antagonist, significantly reversed the hyperalgesia in a dose-dependent manner for at least 48 h. No effect of MK801 was observed in the control group. These data provide evidence that Mg deficiency could constitute a new model of hyperalgesia involving NMDA receptors.

Abstract
The involvement of serotonin (5-HT) in the modulation of nociceptive impulse in the spinal cord has been widely studied. However, its activity, considering the nature of noxious stimuli and the type of 5-HT receptors involved, merits to be further elucidated. The present behavioural study was performed to compare the dose-antinociceptive effect relationship of 5-HT in rats, after intrathecal (i.t.) injection (10 microliters/rat), using mechanical (paw pressure), thermal (tail immersion and tail-flick) and chemical (formalin) pain tests. In rats submitted to the paw pressure test, 5-HT was found to possess a dose-dependent antinociceptive activity (0.01, 0.1, 1, 10 and 20 micrograms/rat) when vocalization threshold was assessed as a pain parameter. A peak effect occurred 5 min after the injection and the effect was maintained for 45 min. The lowest active dose was 0.1 microgram (maximum increase in vocalization thresholds, 23 +/- 3%) and a plateau was observed for 10 micrograms and 20 micrograms (maximum increase in vocalization thresholds, 72 +/- 7% and 71 +/- 6%, respectively). When paw withdrawal was assessed, 5-HT induced a weak hyperalgesic effect for the highest dose (60 micrograms), while other doses were ineffective. In the tail-immersion (warmth and cold) and tail-flick tests, different doses (0.01, 0.1, 1, 10, 30, 60 and 100 micrograms/rat) were studied. In the two immersion tests, only the highest doses (60 micrograms and 100 micrograms) significantly increased the withdrawal thresholds from 5 to 45 min after the injection. The maximum effect was observed at 5 min (23 +/- 4% and 21 +/- 6% for 60 micrograms; 27 +/- 3% and 30 +/- 6% for 100 micrograms in the warmth and cold immersion test, respectively). In the tail-flick test, the doses of 30, 60 and 100 micrograms/rat dose-dependently and significantly increased the withdrawal thresholds from 5 to 45 min after the injection, with a maximum effect at 5 min (30 +/- 5% for 30 micrograms; 37 +/- 6% for 60 micrograms; and 45 +/- 4% for 100 micrograms). In the formalin test, 5-HT (10, 25, 50, 75 and 100 micrograms/rat) produced dose-related antinociception. The nociceptive response (licking of the injected paw) was significantly reduced from 25 micrograms (-59 +/- 11%) in the early phase, whereas the lowest active dose in the late phase was 50 micrograms (-46 +/- 17%). For both phases, a total inhibition was obtained with 100 micrograms. It is concluded that the effect of 5-HT on pain tests may differ according to the applied stimulus and the parameter assessed; unspecific effects of 5-HT may modify motor reactions to noxious stimuli. Mechanical test (assessment of vocalization) was the most sensitive to 5-HT. These observations are of importance in order to further study the pharmacological mechanisms involved in 5-HT spinally induced antinociception.
