Objectives: Rehmanniae Radix Preparata (RRP) has been used as a traditional remedy to treat gynecology and endocrine diseases. Recently, studies on antioxidant and anti-inflammatory effects of RRP have been reported, so it was judged that RRP extracts would have an anti-depressive effect. Methods: We investigated the anti-neuroinflammatory and anti-depressive effect of RRP on lipopolysaccharide (LPS)-induced depression and LPS-stimulated BV2 microglia. RRP inhibited the LPS-stimulated excessive release of nitrite in the BV2 cells. RRP also significantly inhibited the inflammatory cytokines such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta and IL-6 in LPS-stimulated BV2 microglial cells. Results: RRP significantly suppressed the LPS-induced mitogen-activated protein kinase (MAPKs) and nuclear factor (NF)-𝜅B activation. In addition, administration of RRP not only inhibited the immobility time in the forced swimming test (FST) but also increased the total travel distance in the open field test (OFT). Also, RRP inhibited the elevation of TNF-alpha, IL-1beta, and IL-6 in brain of LPS-injected mice. Conclusions: Considering the overall results, our study showed that RRP exhibited the anti-neuroinflammatory and anti-depressive activities via deactivation of MAPKs and NF-𝜅B.

Objectives: The purpose of this study was to examine the anti-depressive effects of BanHaHuBakTang-kami (BHHBT) on an animal model of depression induced by chronic immobility stress. Methods: Mice were treated daily with immobilization stress for 2 hours over a period of 21 days. To examine the effect of BHHBT, we performed behavioral, biochemical and histological analysis to measure immobility time (FST), brain neurotransmitter concentration (HPLC, ELISA), hippocampal damage (H&E staining) and CRF-R1 expression (immunohistochemistry). Results: BHHBT has reduced the immobility time of immobilization stress exposed mice in the forced swimming test. BHHBT has increased the amount of serotonin in the brain. BHHBT has increased the expression level of serotonin in the brain. BHHBT 540 mg/kg were sufficient to prevent tissue damage in the hippocampus region. BHHBT has reduced the expression level of CRF receptors in the hippocampus region. Conclusions: These results suggest that BHHBT may have anti-depressive effects on mice treated with immobilization stress by reducing immobility, increasing brain serotonin concentration and reducing CRF-R1 expression in the hippocampus region.

Objectives: The purpose of this study was to evaluate anti-depressive effects of exercise on child and adolescent and its association with brain derived neurotrophic factor (BDNF). Methods: Twenty nine middle school boys (age $13.3{\pm}0.7$) were divided into two groups, 15 boys for control group and 14 in the experimental group. The control group participated in a regular exercise program, 3 times a week for 15 weeks. During the same period, the experimental group participated in an aerobic exercise program specifically designed to enhance anti-depressive effect of exercise. Serum BDNF level and its performance of each group on the Beck Depression Index (BDI), Children's Depression Inventory (CDI), Screen for Child Anxiety Related Emotional Disorders (SCARED), Aggression Questionnaire (AK-Q), and Stroop task were compared before and after the exercise program. Results: Scores of BDI, CDI, SCARED, and AK-Q were significantly lower in both groups after the exercise programs compared to those before the programs. The Stroop task performances were significantly improved after the programs. However, there were no significant differences between two exercise programs, except SCARED separation anxiety, AK-Q physical, and verbal aggression scores. Also, no association was found between serum BDNF level and anti-depressive effects of exercise. Conclusion: Our preliminary results suggest a possible effect of exercise on depression, anxiety, aggression, and cognition of child and adolescents.

Sogeunjung-tang (S-tang) is a traditional Korean medicine that has been used for the therapy of anxiety disorder in a variety of clinical situations. However, no study has investigated this effect. The aim of this study was to investigate the effectiveness of S-tang for reducing depression in animal model. The anti-depressant effect of S-tang was investigated in ICR mice by using forced swimming test (FST). After FST, we analyzed the blood biochemical parameters from blood. The immobility time was significantly decreased in the S-tang oral administration or pharmaceutical acupuncture group compared with the control group at 14 days (p < 0.05). The anti-depressant effect of S-tang was higher than that of fluoxetine (a classical anti-depressant). S-tang or fluoxetine significantly decreased the creatine kinase and lactate dehydrogenase level compared with the control group (p < 0.05) but not glucose, protein, and blood urea nitrogen level. Further investigation of S-tang as a potential pharmacologic agent in the management of depression related anxiety is warranted.

Obesity increases the risk of developing metabolic diseases such as hypertension, type 2 diabetes, hyperlipidemia, and cardiovascular diseases, as well as some cancers. To prevent the occurrence of these diseases and death, it is essential to manage obesity. Though there are several treatments for obesity, lifestyle interventions, such as diet and exercise, and drug therapy are most widely used in clinical practice. Among the anti-obesity drugs available, the weight loss effect of naltrexone/bupropion has been well-proven. We present a case study in which naltrexone/bupropion, a glucagon-like peptide-1 agonist, and a sodium-glucose transporter 2 inhibitor showed significant weight loss and improved metabolic parameters. Additionally, the management of type 2 diabetes and hypertension, which are common diseases in patients with obesity, was also included.

Objectives : Investigation of the antidepressant effect of Glycyrrhizae Radix (GR) through the anti-inflammatory effect. Methods : Depression in rats was induced by LPS (i,p.3days). The rats were treated with GR100 mg/kg (GR 100) or GR400 mg/kg (GR 400). The depressive immobility was examined with Tail Suspension Test(TST) and Forced Swimming Test(FST). The expression of nuclear factor-${\kappa}B$(NF-${\kappa}B)$, $I{\kappa}B$ was measured with western blotting. The concentration of corticosterone, cytokine in plasma was measured with ELISA. The expression of c-Fos in the paraventricular nucleus(PVN) and tyrosine hydroxylase(TH) in the locus coeluleus(LC) were measured with immunostaining method. Results : In the TST, GR400 group significantly decreased immobility time compared with the LPS group. In the FST, GR100, GR400 group significantly decreased immobility time comparing with the LPS group. c-Fos expression in GR100 and GR400 group was decreased comparing with the lipoplysaccharide(LPS) group. The $I{\kappa}B$ expression of GR100 and GR400 group was increased comparing with the LPS group. The level of corticosterone of GR100 group was decreased comparing with the LPS group. The concentration of cytokine of GR100 and GR400 group was decreased comparing with the LPS group. TH expression in the LC was increased in LPS group, but in GR100 and GR400 group was not shown significant decrease. Conclusion : According to this results obtained, GR has antidepressant effects by the anti inflammatory action through the suppression of HPA axis activity, not through the action against the catecholaminergic system.
