ABSTRACT
Objective To investigate the efficacy of Madopar on vascular parkinsonism with paroxysmal atrial fibrillation(VPD+ PAF)in elderly patients and its effect on the autonomic nervous system. Methods We recruited 50 patients aged over 60 with VPD + PAF into this randomized controlled trial.Based on sinus rhythm recorded by 24 hour ambulatory electrocardiogram ,individuals with an average heart rate below 60 times per minute were assigned into a sinus bradycardia group (n＝15)and those with a normal average heart rate were randomly assigned into a normal rate group (n＝20)or a control group (n＝ 15)by drawing lots.The control group was given routine care for 12 weeks ,while the other two groups were treated with Madopar plus routine care for 12 weeks. The three groups were examined using UPDRS-3 ,dynamic electrocardiogram ,heart rate variability , echocardiography ,and plasma acetylcholine(ACH)levels 1 day before treatment ,4 weeks and 12 weeks after treatment ,and atrial fibrillation frequency 2 weeks after treatment. Results UPDRS-3 scores decreased significantly in the sinus bradycardia group and the normal rate group after treatment for 4 weeks and 12 weeks ,compared with those before treatment (P＜0.05) ;UPDRS-3 scores in the control group did not show statistically significant changes at week 4 after treatment but decreased significantly at week 12(P＜0.05).UPDRS-3 scores in the sinus bradycardia group and the normal rate group were lower than those in the control group after treatment for 4 weeks and 12 weeks(P＜0.05). The total effectiveness rates in the sinus bradycardia group (86.7%,n＝13)and the normal rate group(85.0%,n＝17)were higher than the rate in the control group(53.3%,n＝8)(P＜0.05).Ach levels in the sinus bradycardia group and the normal rate group significantly decreased after treatment for 4 weeks and 12 weeks ,compared with before-treatment levels ,but no significant difference was observed between before-and after-treatment levels in the control group. Frequencies of AF in the sinus bradycardia group(5.6 ± 3.5)and the normal rate group(5.2 ± 4.1)were significantly lower than in the control group(8.4 ± 5.2)(P＜0.05). Conclusions Madopar can depress vagus nerve activity ,relieve VPD+ PAF symptoms ,and reduce the frequency of AF ;Heart rate variability and ACH level are potential predictors of clinical efficacy of Madopar in VPD patients.
ABSTRACT
Objective: To study whether Zhichan Granule could enhance the effect of Madopar for treating Parkinson's disease (PD). Methods: Subacute PD model induced by methylphenyltetrahydropyridine (MPTP) in mice was adopted and 105 male C57 mice were randomly divided into seven groups with 15 in each group,they were control group, model group, Zhichan Granule in low dose (3.5 g/kg) medium dose (9.0 g/kg), and high dose (22 g/kg) combined with DOPA (50 mg/kg) groups, Zhichan Granule (22 g/kg), and Madopar (50 mg/kg) groups, respectively. Behaviors of mice in each group were observed by rollover and pole climbing method. The content of striatum dopamine and the number of dopamine neurons of substantia nigra were detected by HPLC and immunohistochemical method. Results: Compared with the Madopar group, the content of striatum dopamine and the number of dopamine neurons of substantia nigra were significantly increased in the group of low-dose Zhichan Granule combined with Madopar, and the behaviors were significantly improved. Compared with the model group, the behaviors were significantly improved in the group of Zhichan Granule. The results indicated that Zhichan Granule in a low-dose could enhance the effect of Madopar for treating PD, resulting in reduction of the dose of Madopar to a certain degree. Conclusion: Zhichan Granule could enhance the effect of Madopar for treating PD, which has nerve protective effect.
ABSTRACT
Objective To investigate the effect of madopar combined with entacapone administration on plasma homocystein ( Hcy) level in patients with Parkinson's disease ( PD) .Methods Thirty healthy person were selected as a control group, 20 PD subjects with no levodopa ( LD) taking were as no treatment group, 63 subjects with madopar were as madopar group and 49 subjects with madopar combining entacapone were as combination group. Meanwhile levodopa concentration in peripheral blood and Unified PD Rating Scale Ⅲ ( UPDRSⅢ) score were measured.The plasma Hcy levels of all the researchers were detected.Results The L-dopa concentration in plasma of combination group was statistically significantly higher than that of madopar group ( P<0.05 ) .The score of UPDRSⅢscale of madopar group and combination group were significantly lower than that of madopar group ( all P<0.05).Compared with control group, the Hcy concentration in non-treatment group, madopar group and combination group were significantly increased ( all P<0.05 ) .And the Hcy concentration in madopar group was significantly higher than those in none treatment group and combination group ( all P<0.05 ) .Conclusion Madopar combined with entacapone therapy can significantly reduce plasma Hcy levels in patients with PD, which may be beneficial to the treatment of PD.

ABSTRACT
Objective:To observe the clinical effect of piribedil and madopar on Parkinson's disease ( PD) . Methods:Totally 58 patients with PD were divided randomly into the treatment group (29 cases) and the control group (29 cases). Piribedil and madopar were used in the treatment group, while only madopar was applied in the control group. Therapeutic effect of both groups was evaluated by UPDRS at the end of 6 courses. Results:The decrease of UPDRS after the remedy in the treatment group was more significant than that in the control group (P<0. 05), and the total effective rate in the treatment group(89. 7%) was significantly higher than that in the control group(65. 5%)(P<0. 05). Conclusion:The clinical effect of piribedil combined with madopar on PD is superior to that of madopar alone, therefore, the combination use is a useful method in the treatment of PD with the value of popularization and applica-tion.
ABSTRACT
Objective To study and analyze the clinical efficacy and safety of madopar and pramipexole in treatment of Parkinson's disease.Methods 120 cases with Parkinson's disease admitted in the Sixth Hospital of Ningbo City from Mar 2013 to Mar 2014 were randomly and evenly divided into combination group and single group,each group had 60 cases. The single group were treated with madopar,while combination group were treated with madopar and pramipexole. The treatment efficiency,incidence and score of adverse reactions in two groups were recorded and compared in order to assess their efficiency and safety. Results The treatment efficiency,adverse reactions in combination group (95.00%,20.00%)were better than single group (58.33%,83.33%),the differences were statistically significant (P<0.05).The score of adverse reactions in combination group after treatment was better than before treatment,the difference was significant(P<0.05 ). While in control group,the score of adverse reactions was a little higher than before treatment,but the difference was not significant. Conclusion Madopar and pramipexole has better efficacy and high safety in treatment of Parkinson's disease.
ABSTRACT
OBJECTIVE: To compare the Madopar(R) (Levodopa Benserazide) test with Insulin Tolerance Test (ITT) as a provocation test for growth hormone (GH). METHOD: One hundred eighty-seven subjects who had not organic disease such as hypothalamic-pituitary disease were studied. Seventy-one subjects underwent an ITT by injection of 0.1 U/kg of regular insulin and blood samples for GH assay were taken at 0, 30, 60 and 120 minutes. One hundred sixteen subjects underwent a Madopar(R) test by administration of Madopar(R) and blood samples for GH assay were taken at 0, 60, 120 and 180 minutes. RESULTS: The GH mean peak response in ITT was significantly higher than that of the Madopar(R) test. Below 50 years, 18 of ITT and 24 of Madopar(R) test showd a GH peak response of less than 5 ng/ml. Above 50 years, 14 of ITT and 53 of Madopar(R) test showd a GH peak response of less than 5 ng/ml. CONCLUSION: The results suggested that the GH response to the Madopar(R) test was much less than that of the ITT. The Madopar(R) test was limited in diagnosis of the adult GH deficiency in normal adults.
