Fig. 6. Bar graphs illustrating glutathione (GSH) concentrations in the right striatum (RS), left striatum (LS), right cortex (RC), and left cortex (LC) after ischemia in the RS by the injection of endothelin (60 pmol in 3 μl). Animals were treated with intralipid (ENDO-INTRA) or 25 mg · kg−1· h−1propofol (ENDO-PROP) for a period of 4 h. Tissue samples were harvested at the end of the infusion period (A ) or 3 days after ischemia (B ) and assessed for GSH content. For A , a series of sham nonischemic animals (SHAM-INTRA) received the control infusion of intralipid for a period of 4 h.
