Protective effect of pergolide on parkinsonian model rats / 中国药理学通报

ABSTRACT

Aim To explore the antioxidation of pergolide on rat models of Parkinson disease and its mechanism. Methods Wistar rats were pretreated daily with pergolide(1.0 mg?kg -1,ip),pergolide combined with sulpiride(25 mg?kg -1) or sulpiride alone for 7 days, and then sacrificed by decapitation. The activity of SOD and GSH in striatum was determined. Unilateral Parkinsonian models were made in rest of the rats by stereotaxically injecting 6-OHDA. After two weeks, apomorphine (APO)-induced rotational behavior of each group was compared, and the concentrations of striatal dopamine (DA),dihydroxyphenyl acetic acid(DOPAC) and homovanilic acid(HVA) were determined by high performance liquid chromatography (HPLC). Result Administration of pergolide for 7 days significantly increased the act- ivities of SOD and GSH in the striatum (P
