线栓性短暂大脑中动脉阻塞模型（啮齿类）

存活脑组织染为红色、梗死区呈白色；以 2 mm 连续冠状切片逐孔染色成像后，测量患侧与对侧半球的梗死面积及总面积，计算患侧相对对侧的梗死面积百分比。

TTC Staining TTC Staining The brain is removed from the skull and placed into a brain slicer mold placed in ice. Razor blades are positioned in the mold to obtain 2mm thick sections. Sections are placed in individual wells of a 24 well tissue culture dish with 500 μl of 2% TTC in 0.1M PBS. The plate is wrapped in foil and placed on a 37°C slide warmer for 30 minutes. TTC is removed and 500ul of fixative is added to each well for storage. Images of the sections are captured by Olympus S2H10 research stereo- microscope and Adobe Photoshop software. The infarct area and total area of the contralateral and ipsilateral hemispheres are measured with Scion image software (Scion Corporation). The percent infarct area is calculated as a percentage of the ipsilateral hemisphere relative to the contralateral hemisphere as previously described. [F2.JPG]]()
