Figure 1From: Neuregulin1β improves cognitive dysfunction and up-regulates expression of p-ERK1/2 in rats with chronic omethoate poisoning The morphological structure of hippocampus, HE × 400. A: Control group, B: Modeled group, C: Treated group (Denatured cell was pointed by black arrow). Hippocampal neurons in control rats were arranged in alignment with nucleolus obviously; In model group, neurons were loosely arranged,with cytoplasm condensed and nucleus pycnosis. In treated group, with neurons arranged closer, the damage was slighter than that in model rats.Back to article page
