After culturing 7 to 14 days, 3 weeks, 4 weeks and 8 weeks, respectively, cerebral slices were fixed, dehydrated and sectioned in cryostat. The sections proceeded with Nissl staining and neurofilament high molecular weight ( NFH) immunohistochemical staining.

CONCLUSION: Decrease of HL activity and hyperlipemia exist in the process of glucocorticoid-induced NFH, but hyperlipemia can be relieved when agents are given to upgrade HL activity, and such agents can improve NFH and delay its progression.
