tive spike-like electrical discharges occur in the nucleus reticularis pontis caudalis and appear to spread to various parts of the visual system (5, 6). The close temporal association between periods of masseter contractions and REM periods could be explained on the basis of the anatomical proximity (within the brain stem) of the motor nucleus of the trigeminal nerve, which is directly respons...

Introduction: In this study the effect of Matricaria recutita extract on acute pain in the presence and absence of flumazenil (antagonist of benzodiazepine) and lesioned paragigantocellularis (PGi) nucleus was investigated. Method: Wistar male rats (250±20 g) were used. Animals were grouped randomly into intact, sham and bilateral lesion of PGi nucleus. Intact and lesioned animals, each...

introduction: 17β-estradiol modulates nociception by binding to estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and gabaa receptors. beside its autonomic functions, paragigantocellularis lateralis (lpgi) nucleus is also involved in pain modulation. the aim of the current study was to investigate the role of the intracellular estrogenic ...

BACKGROUND Nonsteroidal anti-inflammatory drugs are effective for arthritic pain, but it is unknown whether they also benefit anxiety and depression that frequently coexist with pain. Using the monoarthritis model, the authors evaluated the activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) in structures implicated in both sensorial and emotional pain spheres, and it was veri...

A case of Cushing's syndrome due to micronodular adrenal disease in a 17-year-old girl is presented. The adrenals showed both black and yellow nodules. Histologically the cells contained lipofuschin and either had a clear cytoplasm or an eosinophilic cytoplasm with a prominent nucleus. Lymphocytes were a prominent feature. No cells of the zona reticularis were identified. The cell of origin of ...

As one of the most important diffused brain modulatory systems, the nucleus locus coeruleus (LC) receives most of its afferents from the nucleus paragigantocellularis (PGi) and plays a major role in the control of drug dependence and some emotional and exciting states. For detailed investigation of the effect of morphine on relationship between these two brain stem nuclei, the activity of the r...
