RESUMEN

Objective To investigate the effects of different doses of pituitary adenylate cyclase- activating polypeptide(PACAP)on the functional and morphological outcome in a mice model of Parkinson' s disease(PD)rendered by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP).Methods Male mice were treated with PACAP 0.02, 0.20 or 2.00 ?g by iv bolus for 7 days after MPTP was administered, and were compared with the saline-treated mice.The immunohistochemistry and Western blot were used to detect the alterations of PD biomarker including tyrosine hydroxylase(TH), dopamine transporter(DAT)and vesicular monoamine transporter2(VAMT2).In addition, monoamine neurotransmitters in the striatum of mice were measured by the high performance liquid chromatography (HPLC).Results TH immunohistochemistry indicated that the number of TH-positive neurons in the substantia nigra was increased in all PACAP-treated mice(PACAP(0.02 ?g/d)group was 93.33?4.87, F=85.85,P
