Résumé
This study was aimed to observe effects of Albizia Julibrissin Flower Total Flavonoids (AJFTF) on the learning and memory abilities and plasma monoamine neurotransmitters 5-HT and NE content of depression model rats . A total of 90 SD rats were randomly divided into the normal group , model group , western medicine group ( Venlafaxine Hydrochloride 0 . 0125 g?kg-1 ) and high , middle and low dosage groups of AJFTF ( equivalent to the crude drug of 10 , 5 , 2 . 5 g?kg-1 ) . Depression model rats were induced by solitary cultiva-tion and chronic unpredictable stress . The learning and memory abilities of model rats were evaluated with the Morris water maze . And the plasma contents of 5-HT and NE were determined by enzyme-linked immunosor-bent assay ( ELISA ) . The results showed that AJFTF ( administered with high , middle and low dosage for 21 days ) significantly shortened the incubation period of the Morris water maze positioning and navigation ( P <0 . 05 or P < 0 . 01 ) , and increased the times of crossing the platform in space exploration ( P < 0 . 05 or P <0 . 01 ) . There was a certain dose-effect relationship . The AJFTF ( high , middle and low dosage ) increased the plasma contents of 5-HT and NE ( P < 0 . 05 ) . It was concluded that AJFTF can improve learning and memory abilities of depression model rats which indicates that AJFTF have potential antidepressant effects . Its action mechanism may be related to increase plasma monoamine neurotransmitter content of 5-HT and NE .
Résumé
This study was aimed to observe effects of herbal pair of semen Ziziphi Spinosae (SZS) and A lbizia Julib-rissin flower (AJF) on cognitive function and serum BDNF among depression patients. A total of 60 depression pa-tients were enrolled and randomly divided into two groups. In the SZS-AJF group, 30 patients were administered with SZS-AJF decoction. In the control group, 30 patients were administered with venlafaxine hydrochloride sus-tained-release tablets. Hamilton Depression Rating Scale (HAMD), Wisconsin Card Sorting Test (WCST), and the serum-brain derived neurotrophic factor (BDNF) were detected before treatment and after six weeks of treatment. The results showed that there were no significant differences on the HAMD score, WCST (Response Administered (Ra), Categories Completed (Cc), Correct Responses (Cr), Perseverative Errors (Pe), Non-perseverative Errors (Npe)), serum BDNF before and after treatment between two groups. Compared with pretreatment, HAMD score, Ra, Cc, Cr, serum BDNF were increased after treatment in both groups. The Pe and Npe were decreased after treatment. There was sta-tistical significance between pretreatment and posttreatment (P< 0.05, or P< 0.01). It was concluded that the herbal pair of SZS-AJF has anti-depressant effect. It can improve cognitive function of depression patients. The anti-de-pressant mechanism of herbal pair of SZS-AJF may be related to the increasing of serum BDNF level.
Résumé
This study was aimed to observe the effects of herbal pair of Semen ziziphi spinosae (SZS) and A lbizia julibrissin flower (AJF) on the quality of life (QOL) among elderly patients with depression. A total of 70 elderly patients with depression were enrolled and randomly divided into two groups. The Chinese medicine group (with 35 cases) was given SZS-AJF decoction, and the western medicine group (with 35 cases) was given venlafaxine hydrochloride sustained-release tablets. The HAMD scale score, QOL Assessment Questionnaire (GQOLI-74), and the Side-Effects Scale Score (TESS) were detected 8 weeks before and after the treatment. The results showed that there was no significant difference on the clinical efficacy between two groups. On the comprehensive assessment of QOL, the physical function dimension, mental function dimension and QOL total score of Chinese medicine group were higher than the western medicine group with significant difference (P < 0.05). There were no significant differences on the material function dimension or social function dimensions between two groups. The HAMD score, physical function dimension, mental function dimension, social function dimension and score of QOL were all higher than the pretreatment score with significant differences in both groups (P < 0.05). The TESS score in Chinese medicine group was lower than the western medicine group. And the main adverse reactions in the Chinese medicines group were nausea and vomiting. It was concluded that the herbal pair of SZS and AJF had antidepressant efficacy. It can improve the QOL among elderly patients with depression.
