Figure 3: Expression of NGAL-MMP-9 complex in the sera of normal donors and stroke patients. (A) A representative Western blot shows the expression of NGAL-MMP-9 complex in the sera of control (C), ischemic (I), and hemorrhagic (H) stroke patients. (B) The levels of NGAL-MMP-9 complex in the sera of normal donors and stroke patients were measured by ELISA. Data were analyzed by a one-way ANOVA with Newman-Keuls post hoc tests. 13 There was a significant induction of NGAL-MMP-9 complex in hemorrhagic stroke patients (*P<0.05) compared with normal donors and ischemic stroke patients.
