Abstract:

BACKGROUND: The establishment of animal models of Parkinson’s disease plays an important role in clinical and basic experiments of Parkinson’s disease, and its stability directly affected study results.
OBJECTIVE: To evaluate the behavior and pathological changes of rats with Parkinson’s disease established by unilateral two-point injection with 6-hydroxydopamine.
METHODS: A total of 62 Sprague-Dawley rats were randomly assigned into experimental group (n=50) and normal group (n=12). Using stereotatic technique, 6-hydroxydopamine was injected into the right substantia nigra compact part and midbrain ventral tegmental area to establish models of Parkinson’s disease in the experimental group. Behavioral changes of rats, tyrosine hydroxylase and dopamine content were observed.
RESULTS AND CONCLUSION: At 2 weeks, after induction with apomorphine, left rotation speed > 7 r/min was observed in only 22 rats of the experimental group. No significant difference in the number of rotation between 2 and 4 weeks was detected (P > 0.05). Tyrosine hydroxylase and dopamine content significantly reduced in the model group. Results indicated that unilateral two-point injection of 6-hydroxydopamine could be used to successfully establish rat models of Parkinson’s disease with similar behaviors and pathologies.
