Embodiment 1

[0026] Embodiment 1 Preparation of acute systemic monkey Parkinson's disease model of the present invention

[0027] 1. Purpose of the experiment

[0028] Establish a systemic MPTP monkey Parkinson's disease model with typical symptoms and conduct a comprehensive evaluation of the model to make it suitable for various researches such as new drug evaluation.

[0029] 2. Experimental method

[0030] 2.1 Experimental animals selected:

[0031] Referring to the inclusion criteria of experimental monkeys (see below), 3 healthy adult macaques were purchased from Chengdu Ping An Experimental Animal Breeding Center. Age 5-7 years, weight 5.0-6.1Kg, two males and one female, represented by M1, M2 and F1 respectively. After passing the inspection and quarantine, they are placed in the Large Animal Breeding Center of the National (Chengdu) Traditional Chinese Medicine Safety Assessment Center (GLP) for breeding.

Embodiment 2

[0109] Example 2 Validate the acute systemic monkey Parkinson's disease model with drugs for the treatment of acute Parkinson's disease and initially establish a related drug screening platform

[0110] A, get the acute systemic monkey Parkinson's disease model that embodiment 1 method establishes;

[0111] B, using currently recognized medicines for the treatment of acute Parkinson's disease (Madopar, Sining) administered to the acute systemic monkey Parkinson's disease model animals of the present invention;

[0112] c, observe the influence situation of candidate drug on the quantitative index of acute Parkinson's disease, and score (with the animal behavior score table of embodiment 1 Table 1), evaluate the medicine of potential treatment acute Parkinson's disease, also verified the present invention simultaneously Feasibility of using acute systemic monkey Parkinson's disease model animals for drug screening.

Abstract

The invention provides a preparation method for an acute general Parkinson's disease monkey model. The preparation method comprises the following step of: continuously applying 0.36 mg / kg of MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) to a monkey for five times once every two days in an intravenous injection way. The invention provides a method for screening a medicament for treating the acute Parkinson's disease. By performing continuous peripheral vein injection of MPTP, an acute general Parkinson's disease monkey model with symptoms similar to those of an advanced-stage Parkinson's disease patient can be established. The model has stable symptoms within 1-4 months after establishment, and recovers rapidly later.

Description

technical field [0001] The invention relates to an acute systemic monkey Parkinson's disease model and a drug screening method thereof. Background technique [0002] There are many experimental animal models of Parkinson's disease (PD), including surgical injury of mice and rats or models of damage caused by stereotaxic injection of 6-hydroxydopa. The most valuable model animals should be species that have similar structure, function and complexity to the human nervous system, especially the basal ganglia of the midbrain. The primate PD animal model can reflect the basic characteristics of PD symptoms, and is currently the animal model closest to human PD, which provides a good foundation and platform for the basic research of PD. [0003] MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) causes damage to dopaminergic neurons in the substantia nigra-striatum region of the central nervous system. Although the hemimonkey Parkinson's disease model is simple to model, low in...
