RESUMO
Meningeal melanocytomas are rare tumours of the central nervous system, most commonly found in the intracranial compartment (posterior cranial fossa). Spinal lesions are uncommon, with the majority being intradural, extramedullary lesions. Intramedullary melanocytomas are extremely rare and are most commonly found in the thoracic region. We report a patient with cervical intramedullary melanocytoma and review the available literature regarding this rare pathology.

The ethanol and water extracts of Sansevieria trifasciata leaves showed dose-dependent and significant (P < 0.05) increase in pain threshold in tail-immersion test. Moreover, both the extracts (100 - 200 mg/kg) exhibited a dose-dependent inhibition of writhing and also showed a significant (P < 0.001) inhibition of both phases of the formalin pain test. The ethanol extract (200 mg/kg) significantly (P < 0.01) reversed yeast-induced fever. Preliminary phytochemical screening of the extracts showed the presence of alkaloids, flavonoids, saponins, glycosides, terpenoids, tannins, proteins and carbohydrates.
