Fig. 2From: Compound Qiying Granules alleviates diabetic peripheral neuropathy by inhibiting endoplasmic reticulum stress and apoptosisPathological changes in sciatic nerve tissue. A The pathological conditions of sciatic nerve tissues were detected by HE staining. Mononuclear cell infiltration indicated by dark color the arrow pointed. B Nerve fiber myelin structure of sciatic nerve tissue was detected by LFB staining. Neuronal demyelination indicated by dark color the arrow pointed. C Sciatic nerve tissue apoptosis was detected by TUNEL staining. The apoptosis cells were indicated by dark color the arrow pointed.
