Effects of Jitai tablet (JTT) on dopamine D2 receptor (D2R) levels in the striatum by immunohistochemical staining (a) (Bar = 5.00 mm) and autoradiography with [125I]IBZM (b). The significant decrease of D2R expression in the striatum was inhibited by JTT pre-treatment, or significantly attenuated by post-treatment with high dose of JTT (JTT-H). Data are expressed as mean ± SD (n = 5). METH group vs. control group: # p < 0.05, ## p < 0.01; JTT treatment group vs METH group: * p < 0.05, ** p < 0.01
