Immunohistochemistry results showed that the gray of PC12 cell cytoplasm appeared shallowing after HFS, suggesting that tyrosine hydroxylase activity decreased; The numbers of visible mitochondria in the cytoplasm, secretory granules, processes and synapse were decreased.

结果：相比对照组，HFS后PC12类神经细胞光镜下突起长度显著缩短，突起个数明显减少；酪氨酸羟化酶免疫组织化学结果显示HFS后PC12细胞胞质灰度降低，提示酪氨酸羟化酶代谢水平下降；电镜下可见胞质中的线粒体、分泌颗粒减少，突起和突触减少。
