1. Temporomandibular inflammation mobilizes parvalbumin and FosB/deltaFosB neurons of amygdala and dorsal raphe
Pathophysiological mechanisms involved in orofacial pain and their relationship with emotional disorders have emerged as an important research area for multidisciplinary studies. In particular, temporomandibular disorders (TMD) have been evaluated clinically from both physiological and psychological perspectives. We hypothesized that an altered neuronal acti

2. Selective 5-HT7 receptor agonists LP 44 and LP 211 elicit an analgesic effect on formalin-induced orofacial pain in mice
ABSTRACT The most recently identified serotonin (5-HT) receptor is the 5-HT7 receptor. The antinociceptive effects of a 5-HT7 receptor agonist have been shown in neuropathic and inflammatory animal models of pain. A recent study demonstrated the functional expression of 5-HT7 receptors in the substantia gelatinosa (SG) of the trigeminal subnucleus caudalis,

3. Evaluation of the orofacial antinociceptive profile of the ethyl acetate fraction and its major constituent, rosmarinic acid, from the leaves of Hyptis pectinata on rodents
ABSTRACT Hyptis pectinata (L.) Poit., Lamiaceae, popularly known as "sambacaitá," is an aromatic shrub largely grown in the Brazilian northeastern. We investigated the antinociceptive effects of the ethyl acetate fraction obtained from the leaves of H. pectinata and of its main constituent rosmarinic acid, on formalin (2%)-, glutamate (25 µM)- and capsaici

4. Phytochemical study and antinociceptive effect of the hexanic extract of leaves from Combretum duarteanum and friedelin, a triterpene isolated from the hexanic extract, in orofacial nociceptive protocols
Combretum duarteanum Cambess, Combretaceae, is a plant widely distributed in Northeastern Brazil and, in folk medicine, stems and leaves are used for pain treatment. We investigated the antinociceptive effects of the hexanic extract of leaves from C. duarteanum and of friedelin, its main compound, in formalin-, glutamate- and capsaicin- induced orofacial no

5. Efeitos do óleo essencial de Ocimum basilicum L. e do (-)-linalol na nocicepção orofacial e na excitabilidade do sistema nervoso de roedores. / EFFECTS OF THE ESSENTIAL OIL OF Ocimum basilicum L. AND (-)-linalool, orofacial nociception NA NA nervous system excitability RODENT
O objetivo deste trabalho foi estudar a ação antinociceptiva do Óleo Essencial (OE) obtido das folhas do Ocimum basilicum e do (-)-linalol no modelo de dor (nocicepção) orofacial e na excitabilidade periférica e central. O gênero Ocimum possui várias espécies com os mais variados usos: antinociceptivo, antiespasmódico, sedativo e como repelente de

6. p-Cymene reduces orofacial nociceptive response in mice
This study investigated the possible antinociceptive effect of p-cymene in different tests of orofacial nociception. The animals (mice) were pretreated (i.p.) with p-cymene (25, 50, 100 mg/kg), morphine (5 mg/kg), or vehicle (0.2% Tween 80+saline), and were then subsequently administered, subcutaneously into their upper lip: formalin, capsaicin, and glutamat

7. Ocimum basilicum leaf essential oil and (-)-linalool reduce orofacial nociception in rodents: a behavioral and electrophysiological approach
The present study investigated the antinociceptive effects of Ocimum basilicum L. (Lamiaceae) leaf essential oil (LEO) and (-)-linalool (LIN) in formalin (2%)-, glutamate (25 µM)- and capsaicin (2.5 µg)- induced orofacial nociception models in mice. The involvement of these substances was further evaluated on the neuronal excitability of the hippocampal de

8. AvaliaÃÃo do efeito antiflamatÃrio e antinociceptivo do α- e Ã-amirina, em modelo de doenÃa periodontal e nocicepÃÃo orofacial em ratos / EVALUATION OF THE ANTINOCICEPTIVE AND ANTI-INFLAMMATORY EFFECT OF α- e Ã-AMIRINA IN A MODEL OF DISEASE PERIODONTAL AND NOCICEPCION OROFACIAL IN RATS.
Este estudo avaliou o potencial antiinflamatÃrio do triterpeno α, β-amirina sobre a periodontite nas fases aguda e crÃnica, em ratos. A periodontite foi induzida pela colocaÃÃo de ligadura ao redor do 2Â molar superior esquerdo. Ratos (n=8) foram prÃ-tratados com α, β-amirina (5 e 10 mg/kg,v.o). Falso-operados e controles positivos

9. Opioidergic orofacial antinociception induced by electroacupuncture at acupoint St36
The participation of opioids in the antinociceptive effect of electroacupuncture was evaluated in terms of nociception produced by thermal stimuli applied to the face of male Wistar rats, weighing 180-230 g. Electrical stimulation (bipolar and asymmetric square wave with 0.5 mA intensity for 20 min) of acupoint St36, located in the anterior tibial muscle 10

10. Avaliação da influencia dos hormonios sexuais na nocicepção da articulação temporomandibular de ratos e estudo dos mecanismos envolvidos / The role of sex hormones in temporomandibular joint nociception and study of the mechanisms involved
The aim of this study was to evaluate the effect of sex hormones on temporomandibular joint (TMJ) nociception in rats and the possible mechanisms underlying their effect. The TMJ injection of 0.5% formalin induced nociception in intact females and gonadectomized males, but not in intact males, suggesting that the physiological level of testosterone protect m

11. The influence of stress on nociception induced in temporomandibular joint / A influencia do estresse sobre a nocicepção induzida na articulação temporomandibular
Recent studies have investigated he role of psychological factor in temporomandibular disorders (TMD). However, the mechanisms responsible for nociceptive changes induced by stress are not established. Thus, the aim of this study was to evaluate the effect of acute, sub-chronic and chronic stress on nociception induced by formalin injection in rats? temporom

12. Mensuração do nivel de ansiedade em ratos, sob influencia da nocicepção em tecidos orofaciais superficiais e profundos
The literature indicates an important interrelation between orofacial pain and psychological alterations, amongst them anxiety. Studies have analyzed the probability of the anxiety playing a role in the painful answers, however there are not works analyzing the influence of orofacial pain on the anxiety level. Thus, the aim of the present study was to determ
