Figure 4.

Continuous treatment with NBP for seven days attenuated the thrombosis in the ischemic artery. (a) SRA was performed seven days after ischemia. Three kinds of imaging results (no thrombus, ACA thrombus, ICA thrombus) of the SRA were showed in both control and NBP group. The white arrows indicated the unobstructed artery of the circles of Willis, and black arrows indicated the position of thrombus. (b) Diameter of middle cerebral artery, which was pointing in figure (a), was measured and continuous treatment of NBP for seven days significantly increased the diameter of MCA. (c) Numbers of all three kinds of thrombosis were presented. Ratio of ICA and ACA thrombus in NBP group was lower than the control group, and no ICA thrombus was observed in NBP group. *p < 0.05.
