Objective:To explore the plasma catecholamines (CAs) concentration of postnatal depression and to analyze the re-lationships between postnatal depression and CAs level. Methods: Using high performance liquid chromatography (HPLC) to mea-sure the subjects"" plasma noradrenaline (NE)、 adrenaline (E) and dopamine (DA) concentration. The postnatal depression group was compared with depression, ante partum and normal group. Results: NE level of plasma in the depression group and the post-natal depression group were all higher than those of normal group P < 0.05). E:there were no significant differences on E level of plasma between two groups. DA level of plasma in the postnatal depression group higher than that of normal group( P < 0.01) but depression group and normal group had no significant difference ( P > 0.05) . Conclusion: the plasma NE increase is relative to postnatal depression episode, the plasma DA may be relative to postnatal depression episode. The relationship between plasma and postnatal depression remains unclear.
