Pilose Antler Extracts (PAEs) Protect against Neurodegeneration in 6-OHDA-Induced Parkinson’s Disease Rat Models

Figure 4

PAEs upregulated the levels of 5-HT, 5-HIAA and 5-HT/5-HIAA in CSF and striatum of PD rat model. HPLC-MS was used to measure 5-HT and 5-HIAA levels. (a) 6-OHDA decreased 5-HT level, and increased 5-HT/5-HIAA in CSF of rats, while 180 mg/kg·d PAEs administration increased 5-HT level, and decreased 5-HT/5-HIAA in CSF. (b) 6-OHDA decreased 5-HT level, and increased 5-HT/5-HIAA in striatum of rats, while 60 mg/kg·d and 180 mg/kg·d PAEs administration significantly increased 5-HT level, and also decreased 5-HT/5-HIAA in striatum (p<0.05 versus model, p<0.01 versus model).
