Figure 2: Expression of MMP-9 in the sera of normal donors and stroke patients. (A) A representative Western blot shows the expression of MMP-9 in the sera of control (C), ischemic (I), and hemorrhagic (H) stroke patients. (B) The levels of NGAL in the sera of normal donors and stroke patients were measured by ELISA. Data were analyzed by a oneway ANOVA with Newman– Keuls post hoc tests. There was a significant induction of MMP-9 in hemorrhagic stroke patients (*P<0.05) compared with normal donors and Ischemic stroke patients.
