CHAT and myeloid sarcoma: In this study, we examined the cholinergic degeneration in this model, and our results revealed that the number of ChAT neurons was significantly reduced in MS of the SAP and SAP+FUS groups both 5 days and 18 days after FUS (Fig. 2), which proves that cholinergic dysfunction was well-established in this rat model, and the results are consistent with our previous results [33–36, 44, 45].
