Effect of Kaixin Jieyu Fang on the ultrastructure of white matter in cerebral ischemic rats (× 20,000).

Transmission electron microscopy revealed that the myelin sheaths surrounding the nerve fibers in the left frontal lobe white matter were occasionally thickened and delaminated (arrow) at 3 days and myelination was more obvious at 7 and 21 days in the model group when compared with the sham operation (sham) group. Compared with the model group, damage to myelin sheath structure was slightly alleviated at 3 days, and myelin sheath thickening and delamination was obviously reduced, leading to an increased number of myelin sheaths (arrows) in the Kaixin Jieyu Fang group, which was similar to the sham group.
