Figure 2
T2-weighted MRI showing the masticatory muscle and brain tissue morphology before (A) and 1 (B), 7 (C) and 28 (D) days post MCAO, and the normalized MRI intensity of the masticatory muscle (E). Coronal sections from anterior to posterior show that there was no extra-cranial injury in A–D. Dotted circles show the left or the right masticatory muscle. High-intensity signal indicates tissue lesion after ischemia. (F) Hematoxylin and eosin staining of the masticatory muscle in rats before (a) and 1 (b), 7 (c) and 28 (d) days after MCAO. R: right hemisphere; L: left hemisphere. Scale bar: 4 mm (A–D); 50 µm (F). |
