Objective: To investigate the effects of WenDan Decoction (WD) on the Dopamine synthesis of Schizophrenia rat model,s striatum. Methods: Immunohistochemistry technology and high-pressure liquid chromatography with electrochemical detector (HPLC-EC) were used to evaluated tyrosine hydroxylase (TH) and DA . Results:WD can increase TH and DA . The composition regularity of WD is that expelling phlegm plus regulating the flow of Qi(EP-RFQ) and invigorating the spleen to clear away damp pathogen plus regulating the low of Qi (ISCADP-RFQ) can mainly accelerate DA synthesis.
