Quantitative analysis of infarct volume 72 hours after reperfusion.

Quantitation of the stroke volume was performed as described in “Materials and methods.” PBS indicates animals injected with PBS (n = 8); Ns, animals injected with neuroserpin (n = 8); Cl-Ns, animals injected with elastase-cleaved inactive neuroserpin (n = 2).P values relative to the PBS-treated animals < .01 are shown, and errors represent SEM.
