In this study, we established a model of Parkinson's disease dyskinesia in rats, and treated these animals with Compound Formula Rehmannia. Compound Formula Rehmannia inhibited the increase in mRNA expression of N-methyl-D-aspartate receptor subunits 1 and 2 and excitatory amino acid neurotransmitter genes, and it inhibited the reduction in expression of γ-aminobutyric acid receptor B1, an inhibitory amino acid neurotransmitter gene, in the corpus striatum. In addition, Compound Formula Rehmannia alleviated dyskinesia symptoms in the Parkinson's disease rats. These experimental findings indicate that Compound Formula Rehmannia alleviates levodopa-induced dyskinesia in Parkinson's disease by modulating neurotransmitter signaling in the corpus striatum.展开更多

Methods: Corresponding treatment was given to rats in model group, Ramipril group, normal control group, low dosage SCF group and high dosage SCF group respectively for 32 days. The expressions of PPARγ and adiponectin Messenger RNA (mRNA) were detected by real-time reverse transcriptase poly-merase chain reaction. Results: The expressions of PPARγ and adiponectin mRNA increased significantly in both low and high dosage SCF groups as compared with the model group, and a positive linear correlation was found between the expressions of PPARγ and adiponectin mRNA. Conclusions: SCF can prevent macrovascular lesion in early stage of diabetes, which is possibly related with up-regulating expressions of PPARγ and activating PPARγ.展开更多

The present study attempted to vedfy whether increasing the amount of DAT can reduce the adverse effects of L-DOPA. The specific radioactive uptake value of DAT in the corpus striatum of the lesioned hemisphere was significantly decreased, but was significantly increased following administration of compound rehmannia formula [Radix rehmanniae preparata (prepared rehmannia root), Concha margantifera usta (nacre), Radix paeoniae alba (white peony alba), Radix salviae miltiotThizae (Danshen root), Scorpio (scorpion), green tea] for 4 weeks. The changes in DAT 1251-beta-carbomethoxy-3 beta-(4-iodophenyl) tropane autoradiography were consistent with those in radioactivity. The results revealed that the compound rehmannia formula can reduce the adverse effects of L-DOPA in treating Parkinson's disease, possibly by increasing the amount of DAT.展开更多
