Attempting to decrease disruption of the blood-brain barrier -glutamate has been implicated in ischemia-induced brain damage following brain trauma such as a stroke. it has also been shown that administration of nmda-receptor antagonists following a stroke is effective in the treatment of stroke by reducing tissue infarction and neuronal cell death. the nmda-receptor antagonist is effective, in part, by decreasing disruption of the blood-brain barrier. it has been suggested that this becomes manifest by a blockade of the neuronal production of reactive oxygen species that occurs as a result of activation of nmda receptors. the other choices listed for the question have no known relationship to the process in question.
