Background: Numerous studies have shown the protective effects of saffron against oxidative damage in a global model of cerebral ischemia, but its effects on brain edema and oxidative ischemic injury in focal ischemic stroke are not completely understood. Therefore, this study was designed to investigate the effects of saffron on brain edema, infarct volume, antioxidant enzyme activity (glutath...

In Escherichia coli manganese superoxide dismutase (MnSOD), the absolutely conserved Glu170 of one monomer is hydrogen-bonded to the Mn ligand His171 of the other monomer, forming a double bridge at the dimer interface. Point mutation of Glu170 --> Ala destabilizes the dimer structure, and the mutant protein occurs as a mixture of dimer and monomer species. The purified E170A MnSOD contains exc...
