  • Abstract
  • Look Inside

Histidine is an efficient scavenger of highly active singlet oxygen and somewhat weaker scavenger of hydroxyl radicals. And it has been shown to protect against reperfusion injury in the heart. The effects of L-histidine were examined in the forebrain is-chemia reperfusion injury of the rat hippocampus (CA-1). Male Wistar rats were treated with the free radical scavenger L-histidine for 30 minutes before transient forebrain ischemia produced by 4-vessel occlusion. The extracellular concentrations of glutamate were measured by cerebral microdialysis.
