The expression and significance of tyrosine hydroxylase in the brain tissue of Parkinsons disease rats

The expression and significance of tyrosine hydroxylase (TH) in brain tissue of rats with Parkinson's disease (PD) were explored and analyzed. A total of 120 clean-grade and healthy adult Wistar rats weighing 180-240 g were randomly divided equally into four groups according to the random number table method. Rats were sacrificed before and after the model establishment for 3, 6 or 8 weeks. The...
