Objectives : The purpose of this study is to analyze animal behavioral changes and related neurobiological mechanisms in recent studies using animal models with pain and depression. Methods : We conducted database search in Pubmed, NDSL, and EMBASE up to January 2021. Included studies were classified as depression-like behavior observed in pain model, pain-like behavior observed in depression model, and pain and depression comorbidity model. The results of pain- and depression-like behaviors, the changes of neurobiological mechanisms, and the treatment methods such as drugs, natural substance-derived chemicals, or acupuncture were analyzed. Results : We included 124 studies (81 studies in depression-like behavior observed in pain model, 19 studies in pain-like behavior observed in depression model, and 24 studies in pain and depression comorbidity model). Pain and depression comorbidity animal models were induced using various methods by drugs or surgery. Von frey test, a method for evaluating mechanical allodynia was the most commonly used for measuring pain-like behavior and the forced swimming test was the most commonly used for measuring depression-likes behavior. The changes of neurobiological factors, such as decrease of 5-hydroxytryptamine and increase of oxidative stress and pro-inflammation cytokines were generally changed in the frontal cortex, hippocampus, thalamus, and spinal cord in all types of models. For treating pain and depression-like behaviors, various types of drugs such as antidepressant, tranquilizer, analgesic, and natural substance-derived chemicals were used. Acupuncture treatment was used in 4 studies. Conclusions : In the future, more diverse studies on the combined model of pain and depression need to be conducted. In addition, it is necessary to establish a mechanistic basis for the development of various treatments by identifying the common mechanisms of pain and depression.

Objectives: Depression is a mood disorder showing low energy, loss of interest, anhedonia, and anxiety. It affects a patients' daily life. This disease is considered a social problem because the patient may commit suicide in extreme cases. JSB is composed of 12 Korean medicinal herbs. It has been prescribed to patients with depression. The objective of this study is to investigate anti-depressive effects of JSB on restraint stress-induced depression in a mouse model. Methods: Depression was induced by restraint stress. Mice were orally administered JSB at 10, 20, or 40 mg/kg for 14 days. Forced swimming test (FST) and open field test (OFT) were performed. Brain-derived neurotrophic factor (BDNF) mRNA level was measured by real time-PCR. Plasma levels of corticosterone and serotonin were measured by ELISA. Blood levels of AST and ALS were measured using a biochemical analyzer. Results: JSB treatment significantly reduced the immobility time in FST. BDNF mRNA level was increased by JSB treatment in the hippocampi of mice. Although the expression of TNF-α was also increased by JSB, such increase was not statistically significant. The increase of corticosterone level in plasma induced by restraint stress was significantly down-regulated by JSB. JSB reduced blood level of AST, but not ALT. Conclusions: JSB has a potential to manage depression, setting a foundation for clinical application of Korean medicine with safety.

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.

Objective : This study is conducted to investigate the effect of Astragali Radix on Post Traumatic Stress Disorder(PTSD) induced by the Single Proposed Stress(SPS). Methods : The experiment was conducted with five groups; SAL groups with only saline treatment, SPS group, SPS + ARX25 group, SPS + ARX50 group, and SPS + ARX100 group. After applying SPS, saline and ARX were administered for 14 days to identify the change of body weight, sucrose intake amount, and behavioral changes through Open Field Test(OFT) and Forced Swimming Test(FST). After the behavioral experiment, plasma corticosterone levels, serotonin, norepinephrine and dopamine concentrations were measured by enzyme-linked immunoassay in medical prefrontal cortex, hippocampus, and amygdala. Brain-derived neurotrophic factor(BDNF) in the hippocampus was measured using Reverse Transcription Polymerase Chain Reaction. Results : Weight change has significantly decreased in the SPS group compared to the SAL group(p<0.05). On day 14, the sucrose intake of rats has significantly increased in the SPS + ARX100 group compared to the SPS group(p<0.05). In OFT, the number of staying in the central space has significantly increased in the SPS + ARX100 group(p<0.01). In FST, immobility has significantly decreased in SPS + ARX50 group and SPS + ARX100 group(p<0.05). The concentration of serotonine, dopamine and BDNF expression has increased significantly in SPS + ARX100 group compared to SPS group(p<0.05) Conclusions : In the SPS-induced PTSD experiment, ARX increased sucrose intake and the numbers of crossing in the central zone space in OFT, decreased immobility time in FST, and increased concentration of serotonin, dopamine, and BDNF. It can be postulated that the ARX could be effective for the treatment of PTSD.

1. Objective This study was done to identify the anti-stress effect of Hyeongbangdojeok-san (HDS), Yanggyeoksanhwa-tang(YST) in Soyangin. 2. Methods Experimental animals were composed of YST, HDS+stress groups which were administered each by 200mg/kg, 400mg/kg and the Saline+stress group. On the 1st day, making the rats forced swim and on the 2nd day, applying Forced swimming test to the rats. After FST, the levels of Corticosterone in the blood were measured. For the study of learning retardation, memory ability and anxiety reaction, experimental animals were composed of YST, HDS+restraint stress groups which were administered each by 400mg/kg, no stress group and the Saline+restraint stress group. Restraint stress were applied 2 hours a day for 3 weeks. On the last day of the 3rd week, Elevated Plus Maze(EPM) was applied to the groups and Morris Water Maze(MWM) was applied to the groups for 7 days. 3. Results 1. As the results of measuring FST which reflects depression, the YST+stress group and the HDS+stress group showed significant effect in comparison with the Saline+stress group. The levels of Corticosterone in the blood were decreased only in the 400mg/kg YST+stress group. 2. As the results of measuring how long EPM which reflects anxiety reaction stayed in the open arm, there was the trend which can suppress anxiety reaction in the HDS+restraint stress group bur no statistical significance. But there was any suppression of anxiety reaction in the YST+restraint stress group. 3. According to the result of MWM, the saline+restraint stress group showed the learning retardation which means increased time arriving at goal compared to the normal group at the second and third day of measurement. On the contrary, a learning retardation was significantly decreased in the YST+restraint stress group at the third day of measurement. 4. Among the Probe trial test a memory loss occurred in the saline+restraint stress group, but memory ability was significantly increased in the YST+restraint stress group. 4. Conclusion: As the results above, Soyangin Yanggyeoksanhwa-tang has significant influence to the antidepression effect, the learning retardation, the anxiety reaction and also in the Hormone level. Hyeongbangdojeok-san has significant influence to the antidepression effect, in the Hormone level, bur not to the learning retardation and anxiety reaction. prefer to drink cold water, and who are suffering from chronic gastritis.

Water and methanol extracts of cricket were examined for their liver protective effects against $CCl_4-intoxication$ in ICR-mice. Serum transaminases (S-GOT and S-GPT), lactate dehydrogense (LDH) and glutathione-S-transferase (GST) activities and TBARS (Thiobarbiturate-reactive substances) content were measured for evaluation of liver protective effects. The activities of GOT, GPT, LDH and hepatic content of lipid peroxide after $CCl_4-treatment$ were higher than normal control but those levels decreased th 74, 50, 101 and 40%, respectively, by the treatment of cricket methanol extract. The anti-fatigue effects of water and methanol extracts investigated by an acute weight-loaded forced swimming test showed significantly prolonged swimming time in the mice administered cricket extracts. These results suggest us that water/alcohol extract of G. bimaculatus may be used as a liver protective food.

The purpose of this study was to evaluate whether wild ginseng (WG) administration could attenuate anxiety- and depression-like behaviors and expression of corticotrophin-releasing factor (CRF) and neuropeptide Y (NPY) following withdrawal from repeated morphine administration in rats. Male rats were administered daily doses of WG (50, 100, or 200 mg/kg, i.p.) for 5 days, 30 min before morphine injection (40 mg/kg, s.c). The anxiety- and depression-like behavioral responses were measured 72 h after the last morphine injection using an elevated plus maze (EPM) and forced swimming test (FST), respectively. Changes in hypothalamic CRF and NPY expressions were also examined by analyzing their immunoreactivities in the hypothalamus. Daily administration of WG significantly reduced anxiety- and depression-like behavior, and elicited the suppression of CRF expression and the stimulation of NPY expression in the hypothalamus. Our results demonstrated that WG extract might be effective at inhibiting the anxiety and depression responses due to morphine withdrawal by possibly modulating the hypothalamus CRF and NPY systems. Furthermore, these findings imply that WG extract can be used for developing new medication to cure or alleviate morphine withdrawal symptoms and to prevent relapses of morphine use.

Objective : The present experiments were designed to study on the immune-enhancing effect of Mountain grown ginseng, Mountain cultivated ginseng, and Panax ginseng Method : In order to compare the immune-enhancing effect of moutain grown ginseng, moutain cultivated ginseng and Panax ginseng, the study was done through the forced swimming test (FST), measurement of T helper Th1, Th2 cytokines and fatigue related factors. Result : Moutain grown ginseng and panax ginseng decreased the immobility time in the FST compared to the control. Glucose, blood urea nitrogen (BUN), creatinine, lactate dehydrogenase (LDH) and Total-protein (T-protein) in serum were investigated. The serum achieved from ginseng administered mouse showed higher BUN, T-protein than the control. moutain grown ginseng administered group showed lower LDH than the control group. moutain grown ginseng administered mouse showed higher glucose than the control. Creatinine was same in either experimental or control group. Ginseng-induced cytokine production in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages were compared. Moutain cultivated ginseng (10-4 dilution) and panax ginseng (10-3 dilution) were increased the interferon $IFN-{\gamma}$ production compared with media control (about 1.6-fold P<0.05) at 48 h. Moutain grown ginseng (10-4 dilution) was increased the $IFN-{\gamma}$ and interleukin IL-4 production compared with media control (about l.4-fold for $IFN-{\gamma}$ and 1.6-fold for IL-4 P<0.05) at 48 h. Moutain grown ginseng (10-3 dilution) and moutain cultivated ginseng (10-4 dilution) were increased the turmor necrosis factor $TNF-{\alpha}$ production compared with $rIFN-{\gamma}$ treated cells (about 1.9-fold for $TNF-{\alpha}$ P<0.05), respectively. Moutain cultivated ginseng (10-3 dilution) was increased the IL-12 production compared with $rIFN-{\gamma}$ treated cell (about 1.7-fold for IL-12 P<0.05). Conclusion : These data suggest that three different three kinds of ginseng act on immune responses in different aspects.

Depression is a type of mood disorder characterized by hypochondriasis, decreased appetite, and insomnia. Depression is a disease that affects more than 100 million people worldwide. 2-Nonadecanone (NAC) is a bioactive substance that constitutes Fomes fomentarius, and NAC is expected to have an antidepressant effect. By using the forced swimming test (FST), we investigated the effects of treatment with NAC on immobility subacutely in rats after oral dosing once a day for 2 days. Serum levels of cytokine interleukin-1 beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) were determined by enzyme-linked immunosorbent assay (ELISA). Nuclear factor-2 (Nrf-2) and inducible nitric oxide synthases (iNOS) were analyzed by western blot method. NAC dose-dependently decreased immobility in the FST. NAC dosedependently decreased FST-induced increase of cytokine levels, as manifested by significantly stronger effects on $IL-1{\beta}$ and $TNF-{\alpha}$ levels at higher doses than the lowest dose of NAC. Western blot analysis showed that Nrf-2 was significantly lower in the NAC-treated group than in the disease-induced group. The iNOS results were also significantly lower in the NAC-treated group than in the other groups. Considering FST results, the antidepressant effect of NAC is effective. Considering the results of cytokine and protein expression, this anti-depressant effect may be related to the anti-inflammatory effect. Therefore, it can be said that the anti-inflammatory effect of NAC increases the antidepressant effect in the FST experiment.
