Mechanism of aqueous fructus aurantii immaturus extracts in neuroplexus of cathartic colons

Figure 2 Relative mRNA expression of 5-hydroxytryptamine receptor 4 and neurofilament-H in rat colon tissue. ^aP < 0.05, ^bP < 0.01 vs control; ^cP < 0.05, ^dP < 0.01 vs model. FAI: Fructus aurantii immaturus; H: High dose (4 g/kg); L: Low dose (1 g/kg); M: Medium dose (2 g/kg); NF-H: Neurofilament-H; 5-HTR4: 5-hydroxytryptamine receptor 4.
