Influence of mannitol and furosemide, alone and in combination, on brain water content after fluid percussion injury.

abstract：BACKGROUND:Several investigations into brain activation caused by pain have suggested that the multiple painful stimulations used in typical block designs may cause attenuation over time of the signal within activated areas. The effect this may have on pain investigations using multiple tasks has not been investigated....
