  • Both ethanol and water extracts of unossified velvet antler were found to exhibit a significant immuno-stimulating activity as measured by carbon clearance test in mice, a remarkable anti-fatigue effect in weight-loaded forced swimming performance in mice, a significant anti-stress effect on immobilization in rats. The antler extracts also showed a weak but significant anti-thrombotic activity. These findings are indicative of adaptogenic properties of antlers and their normalizing effects during stressful condition.

  • Depression is very common mental disorder, so many people suffer from it, which makes the treatment of depression important. Many drugs to treat depression were developed and being prescripted. But they have a lot of side effects, so it needs to develop drugs without side effects or with less side effects. Herbal medicines have been used to treat not only physical disorder but also mental disorder and it has been reported that they have less side effects. Therefore, there is the need to discover and use herbal medicine with antidepressant effect. The purpose of this study was to reseach Antidepressant effect of Licium chinense Mill. and its influence on serotonin and its metabolite of depression model rats. We used 'forced swimming test(FST)' to know antidepressant effect of Licium chinense Mill. and HPLC to check the influence on serotonin and its metabolite(5-HIAA) of Licium chinense Mill. after rats' brains were divided into cerebral cortex, striatum, hypothalamus and hippocampus. The results were obtained as follows : In the study of antidepressant effect by 'forced swimming test(FST)' method, Licium chinense Mill. had a significant antidepressant effect. In the study of influence on serotonin and 5-HIAA by HPLC, Licium chinense Mill. mainly increased serotonin and 5-HlAA of cerebral cortex and striatum signigficantly among 4 parts of rat's brain above-mentioned. These results suggest that Licium chinense Mill. has antidepressant effect that may be related with the increase of serotonin and its metabolite as its mechanism, but more precise experiments will be need to prove their relation.

  • A series of 5-alkoxy-tetrazolo[1,5-a]quinolines were synthesized to evaluate their anticonvulsant and antidepressant effects. Anticonvulsant effects and neurotoxicity of the compounds when injected intraperitoneally to mice were determined by a maximal electroshock (MES) test and a rotarod test, respectively. Only three of the synthesized compounds (4a, 4b, 4c) displayed anticonvulsant activity at a dose of 300 mg/kg. Most of the compounds significantly reduced immobility times during the forced swimming test (FST) at a dose of 100 mg/kg, indicative of antidepressant activity. Among the compounds, 5-(2-fluorobenzyloxy)tetrazolo[1,5-a]quinoline (4k) reduced immobility time by 66.85% at 30 mg/kg compared with the same dose of Fluoxetine, which reduced immobility time by 52.30%. According to the results of the 5-Hydroxytryptophan induced head-twitch test and yohimbine toxicity potentiation test, the noradrenergic system seems not to be involved in the antidepressant-like effect of compound 4k while the serotonergic system seems a little to be involved.

  • Depression is one of the most common neuropsychiatric disorders and has been associated with the neuroendocrine system and alterations in behavior. Schisandra chinensis Baillon is one of major medicinal plants used as a Korea medicine and food sources, and has been processed in the fields of various food products and medicinal herbs. The chronic mild stress (CMS) protocol is widely used to evoke depressive-like behaviors in laboratory mice or rat. The CMS procedure induced some behavioral changes that are compatible with the common expectations, i.e. 'anhedonic' behavior and can affect corticosterone level. The present study, Schisandra chinensis extract administration by daily gavage from the 3 weeks exhibited an antidepressant-like effect on CMS-induced depression in mice. Schisandra chinensis extract administration at dose of 200mg/kg significantly increased the sucrose consumption, and decreased the immobility durations in forced swim test and tail suspension test. Furthermore the corticosterone level decreased than control group. In conclusion, Schisandra chinensis extract showed antidepressant-like effects on sucrose preference test, forced swimming test and tail suspension test based on CMS model.

  • Objectives: In this research, the effect of samul-tanggahyangbuja on depression and learning in ovariectomized rats subjected to repetitive stress were assessed. Samul-tanggahyangbuja is the prescription consisting of Samul-tang and Cyperi Rhizoma. Methods: Ovariectomized rats were repeatedly stressed over a 2-week period. After being orally medicated with samul-tanggahyangbuja (100 or 400 mg/kg), rats performed the Morris water maze test and forced swimming test, and social exploration was assessed in a behavior test. As well, sucrose intake was measured and measurements of blood serum corticosterone and the change of interleukin-$1{\beta}$ (IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in blood samples were made. Results: 1. In the Morris water maze test, rats medicated with 100 mg samul-tanggahyangbuja mastered the maze in a shorter time on the 4th day in comparison with the control group, while rats medicated with 400 mg samul-tanggahyangbuja mastered the maze more quickly (p<0.05 on the 3rd day ; p<0.01 on the 4th day, as compared to control). 2. Immobility time in the forced swimming test was significantly decreased in rats receiving 400 mg samul-tanggahyangbuja compared with the control group (p<0.05). 3. Sucrose intake and active social behavior of rats receiving 400 mg samul-tanggahyangbuja were markedly increased in comparison with the control group (p<0.01). 4. Blood serum corticosterone measurements revealed decreased blood serum corticosterone level after medicating with samul-tanggahyangbuja. But it was not statistically significant. 5. Treatment with either dose of samul-tanggahyangbuja significantly reduced IL-$1{\beta}$ and TNF-${\alpha}$ (p<0.05). Conclusions: These results suggest that samul-tanggahyangbuja possesses the anti-depressant and cognitive-enhancing activities related to menopause.

  • This study investigated the stimulative or sedative effects of inhaling fragrant essential oils (EOs) by using a forced swimming test (FST) with mice. This behavioral test is commonly used to measure the effects of antidepressant drugs. The inhalation by mice of EOs, such as ginger oil (p<0.05), thyme oil (p<0.05), peppermint oil (p<0.05), and cypress oil (p<0.01) resulted in 5% to 22% reduction of immobility. The same results were achieved when over-agitation was artificially induced in the mice by an intraperitoneal injection of caffeine (a psycho-stimulant). In contrast, inhalation of some EOs by the mice resulted in increased immobility. To evaluate more correctly the sedative effects of EOs, the immobility of over-agitated mice induced with caffeine was ascertained after the inhalation of various EOs. Inhalation of lavender oil (p<0.01) and hyssop oil (p<0.01) increased the immobile state in mice that were treated with caffeine. The results of this study indicate that the inhalation of essential oils may induce stimulative or sedative effects in mice.
