Pathologically, it is characterized by loss of dopamine (DA) neurons and the presence of cytoplasmic inclusions (Lewy bodies, LBs) in surviving neurons in the substantia nigra pars compacta (SNc), accompanied by the presence of dystrophic neurites (Lewy neurites, LNs).

However, in this study, we not only detected DNA synthesis but also observed cell division in some morphologically differentiated neuronal PC12 cells bearing long neurites.

To explore the effects of a low-frequency modulating magnetic field on the brain wave rhythm, the neurotransmitters in Wistar rat brains were detected and the nerve synapses of the rats were observed through an electronic microscope.

Results Denatured necrosis occurred on the surface of hypothalamic periosteum with no cells and there was a large amount of starchy bodies and hydrops in foci with angiectasis of choroid plexus and necrosis and calcification in tunicaintima of vesicles,and mitochondria in the nerve synapse disappeared and part of anteroposterior membranes .
