Fig. 4From: Alterations of monoamine neurotransmitters, HPA-axis hormones, and inflammation cytokines in reserpine-induced hyperalgesia and depression comorbidity rat modelReserpine-induced changes in monoamine neurotransmitters and their metabolic products. A The model group showed decreased concentration of 5-HT. B The model group showed decreased concentration of NE. C No significant difference existed in concentration of DA. D No significant difference existed in concentration of 5-HIAA. E No significant difference existed in concentration of HVA. F No significant difference existed in concentration of DOPAC. Data is expressed as the mean ± SD. ****p < 0.0001, compared with their respective control groupBack to article page
