|
Objectives: The investigation of the antidepressant effects of Citri Reticulatae Viride Pericarpium (CR)
Methods: we performed the forced swimming test. Also the expression of Tyrosine Hydroxylase (TH) was measured with immunohistochemical method at the Ventral Tegmental area (VTA), Locus coeruleus (LC). The Adrenocorticotropic Hormone (ACTH) level was measured in plasma.
Results: 1. The duration of immobility in the forced swimming test was significantly decreased in the CR 100 mg/kg, CR 400 mg/kg groups, comparing with the control group (p < 0.05, p < 0.001). 2. TH expressions in the VTA, LC were significantly reduced in the CR 100mg/kg and CR 400mg/kg treated group, comparing with the control group (p < 0.05, p < 0.001). 3. ACTH expression in plama was significantly reduced in the CR 100 mg/kg treated group, comparing with the control group (p < 0.05).
Conclusions: According to the above results, it can be considered that Citri Reticulatae Viride Pericarpium has antidepressant effect through the reduction of TH expression at VTA, LC and ACTH level in plasma.
