Background. Zinc (Zn), copper (Cu) and manganese (Mn) are involved in regulatory systems in the cell. Their role in neuromodulator activities and redox reactions has been implicated in the pathogenesis of neurological disorders. The aim of this study was to determine changes of Zn, Cu and Mn levels in brain tissue, blood and urine after experimental subarachnoid haemorrhage (SAH). The possible importance of these trace minerals on the pathogenesis of SAH was also discussed.
