Whole cell recordings of fura-2 dialyzed vagal neurons of brain stem slices were used to monitor interstitial glutamate accumulation within the dorsal vagal complex. Anoxia produced a sustained outward current (60 pA) and a moderate [Ca(2+)](i) rise (40 nM). These responses were neither mimicked by
About 250 mumol/kg tetrachloromethane is metabolized by male Sprague-Dawley rats receiving a dose of 500 mumol/kg by inhalation. Determination of enzyme activities and histopathological assessment show that various parameters reflecting cellular injury do not differ for the same amount of
