  • Brassica juncea is a polyphenols enriched edible plant, with diverse medicinal uses of different parts of which have been mentioned in the Ayurveda. The effects of 10 daily oral doses (100, 200, and 400 mg/kg/day) of a methanolic Brassica juncea leaf extract in rat models of anxiety using nondiabetic and alloxan-diabetic rats were quantified. In all the three behavioural tests used, i.e. elevated plus maze, open field, and social interaction tests, anxiolytic-like activity of the extract was observed in the diabetic animals only. Quantitatively, the efficacy of the highest tested dose of the extract in these tests was always less than those observed after its lower ones. These observations provide further experimental evidences for the conviction that Brassica vegetables could as well be useful for combating diabetes associated mental health problems.

  • 목 적: 본 연구는 갱년기 우울증 모델에서 사물탕가향부자(SGH)의 항우울 효능 및 면역반응에 대한 실험적 유의성을 확인함으로써 임상적인 응용에 기초자료로 사용하기 위하여 시행되었다. SGH가 반복적인 스트레스를 가한 난소적출 흰쥐에서 항우울행동 효과와 estradiol level 및 anti-inflammatory cytokine인 IL-4에 미치는 영향을 연구하고자 하였다. 방 법: 난소적출 흰쥐에 2주간 반복적인 스트레스를 주고 동시에 SGH(200 and 400 mg/kg/day)를 경구 투여한 후 행동검사인 Elevated Plus Maze(EPM)를 통한 우울행동과 혈청 estradiol, IL-4의 변화를 측정하였고, 또한 뇌 내 Locus coeruleus(LC)와 Paraventricular Nucleus(PVN)에서 IL-4의 변화를 측정하였다. 결 과: 1. EPM에서 SGH 400 mg 투여군은 대조군에 비해서 open arms에 머무는 시간이 현저히 증가하였고, closed arms에 머무는 시간이 현저히 감소하였다. 2. EPM에서 SGH 투여군은 대조군에 비해서 open arms와 closed arms를 교차하는 횟수가 증가하였으나, 통계적인 유의성은 없었다. 3. Estradiol 측정에서 SGH를 투여한 후 estradiol 수준이 현저하게 증가하였다. 4. IL-4 측정에서 SGH를 투여한 후 혈청 IL-4 수준이 현저하게 증가하였다. 5. 뇌에서의 IL-4 면역반응은 대조군에서 감소하였으나, SGH를 투여한 후 LC와 PVN에서 IL-4 수준의 유의성 있는 변화는 나타나지 않았다. 결 론: 이상의 결과로 사물탕가향부자는 난소적출 흰쥐의 항우울행동과 면역조절에 유효함을 알 수 있었다.

  • The aim of this study was to evaluate the effects of Jowiseungcheongtang compared with St. John's wort in the chronic mild stress(CMS) animal model of depression. Wistar rats were used for this study. The subjects were divided into 4 groups (Naive group: without CMS procedure, CMS-vehicle: water was administered during CMS procedure, CMS-Jowiseungcheongtang: Jowiseungcheongtang was administered after 5 weeks of CMS procedure, CMS-St. John's wort: St. John's wort was administered after 5 weeks of CMS procedure) During 9 weeks of CMS procedure, The change of the consumption of sucrose and the changes of weights were measured. After CMS procedure, Morris water maze test, open field test, elevated plus maze test and Western blotting were measured. The results were as follows. 1. The consumption of sucrose solution was significantly reversed in Jowiseungcheongtang group and relatively reversed in St. John's Wort group at 7 week. 2. In open field test, Neither Jowiseungcheongtang nor St. John's wort group showed statistically significant change of exploratory activity. In EPM test, St. John's Wort group showed significant decrease of total arm entry in comparison with Naive group. And Jowiseungcheongtang group was showed no significant change. 3. In Morris water maze test, St. John's Wort group showed significant increase in escape latency of the last Morris water maze trial. And in water maze probe test, there was no significant change. 4. St. John's Wort group showed relative increase in LP1 division of 5HT1A receptor compared with Naive group. Both St. John's Wort and Jowiseungcheongtang group showed relative increase in P2 division of GluRl compared with Naive group. These results suggest that Jowiseungcheongtang is as effective as St. John's Wort in the treatment of depression.

  • Acupuncture has been used for the treatment and prevention of stress-related disorders. In the present study, the effect of electroacupuncture on the behavioral and biochemical responses to restraint stress was evaluated in rats. Sprague-Dawley male rats underwent to immobilization stress for 21 days (6 hours/day). Electroacupuncture (2 Hz, 2 mA, and 10 minutes) was applied either to the acupuncture point HT7 (Shenmen) or the nonacupuncture point in the tail for the last 7 days. Rats were randomly divided into four groups: the normal group (n=10, without the restraint stress), the stress group (n=10, with restraint stress), the HT7 group (n=10, with restraint stress and electroacupuncture to HT7), and the NA group (n=10, with restraint stress and electroacupuncture to the nonacupuncture point). The anxiety-related behavior was tested using the elevated plus maze and the Vogel test on day 22. The expression of tyrosine hydroxylase in the locus coeruleus was measured by immunohistochemistry. R maze and the Vogecreased the response of the anxiety-related behavior. The number of tyrosine hydroxylase-immunoreactive cells were also increased. The HT7 group showed a significant decrease of anxiety-related behavioral response, compared to the stress group. The tyrosine hydroxylase-immunoreactive expression was also decreased in the HT7 group. These findings suggestthat electroacupuncture to HT7 might play a role in reducing the stress-related responses, which may be helpful for the treatment of stress-related disorders.

  • Background: Panax vietnamensis Ha et Grushv. or Vietnamese ginseng (VG) is a recently discovered ginseng species. Studies on its chemical constituents have shown that VG is remarkably rich in ginseng saponins, particularly ocotillol saponins. However, the psychopharmacological effects of VG have not been characterized. Thus, in the present study we screened the psychopharmacological activities of VG in mice. Methods: VG extract (VGE) was orally administered to mice at various dosages to evaluate its psychomotor (open-field and rota-rod tests), sedative-hypnotic (pentobarbital-induced sleeping test), anti-stress (cold swimming test), anxiolytic (elevated plus-maze test), and cognitive (Y-maze and passive-avoidance tests) effects. Results: VGE treatment increased the spontaneous locomotor activity, enhanced the endurance to stress, reduced the anxiety-like behavior, and ameliorated the scopolamine-induced memory impairments in mice. In addition, VGE treatment did not alter the motor balance and coordination of mice and did not potentiate pentobarbital-induced sleep, indicating that VGE has no sedative-hypnotic effects. The effects of VGE were comparable to those of the Korean Red Ginseng extract. Conclusion: VG, like other ginseng products, has significant and potentially useful psychopharmacological effects. This includes, but is not limited to, psychomotor stimulation, anxiolytic, antistress, and memory enhancing effects.

  • 본 연구는 불안, 불면증, 우울증 또는 삶의 질에 대하여 지치(Lithospermum erythrorhizon) 유래 naphthoquinone, 즉 shikonin의 영향을 고찰하고, 확실히 밝혀지지 않은 메카니즘을 규명하고자한다. 우리는 지치의 주요성분인 naphthoquinone이 스트레스에 의한 수면장애, 강제수영에 의한 우울, 미로에 의해 유발된 불안현상 등의 조절에 영향을 미칠 것이라고 가설을 세웠다. 수컷 쥐를 이용하여 부동 혹은 수영시간, 수면시간, open arms으로 지속시간 및 진입빈도를 측정하고 기록하였다. Naphthoquinone(10, 30 & 100mg/kg)의 투여군에서 GABAA receptor의 활성으로 일어나는 barbiturate-유도 수면을 증가시켰다. 미로에서 open arms 상태로 지속되는 시간이 증가되고, 강제수영에서 부동시간이 줄었다. 결과적으로 naphthoquinone은 불안을 완화, 수면과 항우울경향이 있고, 불안, 불면과 우울증에서 효과적인 치료효과가 있었다.

  • Behavioral analysis in mice provided important contributions in helping understand and treat numerous neurobehavioral and neuropsychiatric disorders. The behavioral performance of animals and humans is widely different among individuals but the neurobehavioral mechanism of the innate difference is seldom investigated. Many neurologic conditions share comorbid symptoms that may have common pathophysiology and therapeutic strategy. The forced swim test (FST) has been commonly used to evaluate the "antidepressant" properties of drugs yet the individual difference analysis of this test was left scantly investigated along with the possible connection among other behavioral domains. This study conducted an FST-screening in outbred CD-1 male mice and segregated them into three groups: high performers (HP) or the active swimmers, middle performers (MP), and low performers (LP) or floaters. After which, a series of behavioral experiments were performed to measure their behavioral responses in the open field, elevated plus maze, Y maze, three-chamber social assay, novel object recognition, delay discounting task, and cliff avoidance reaction. The behavioral tests battery revealed that the three groups displayed seemingly correlated differences in locomotor activity and novel object recognition but not in other behaviors. This study suggests that the HP group in FST has higher locomotor activity and novelty-seeking tendencies compared to the other groups. These results may have important implications in creating behavior database in animal models that could be used for predicting interconnections of various behavioral domains, which eventually helps to understand the neurobiological mechanism controlling the behaviors in individual subjects.

  • 목 적: 본 연구는 만성 스트레스로 인한 갱년기 우울증 모델에서 사물탕가향부자(SGH)의 항우울 효과를 검증하여 실험적 유의성을 확인하고자 시행되었다. 방 법: 난소적출 흰쥐에 4주간 만성 스트레스를 가하고 SGH(100 and 400 mg/kg/day)를 투여한 후 행동검사인 sucrose intake test(SIT), elevated plus maze(EPM), forced swimming test(FST) 및 Morris water maze test(MWMT) 등을 통한 우울행동 변화와 혈청 corticosterone(CORT), IL-$1{\beta}$ 및 IL-4 등의 변화를 측정하였고, 또한 뇌 내 hippocampus와 hypothalamus에서 5-HT의 변화를 측정하였다. 결 과: 1. SIT에서 SGH 400 mg/kg/day 투여군은 대조군에 비해서 자당 섭취가 유의하게 증가하였다(p<0.05). 2. EPM에서 SGH 400 mg/kg/day 투여군은 대조군에 비해서 open arms에 머무는 시간이 유의하게 증가하였고(p<0.01), open arms와 closed arms를 교차하는 횟수도 대조군에 비해서 유의하게 증가하였다(p<0.05). 3. FST에서 SGH 100 mg/kg/day, 400 mg/kg/day 투여군 모두 대조군에 비해서 immobility시간이 유의하게 줄어들었다(SGH 100 p<0.05, SGH 400 p<0.01). 4. MWMT에서 SGH 100 mg/kg/day, 400 mg/kg/day 투여군은 모두 대조군에 비해서 실험 4일째에서 acquisition trials 수행 시간이 유의하게 단축되었고(p<0.05), SGH 400 mg/kg/day 투여군은 대조군에 비해서 retention trials 수행 시간이 유의하게 증가하였다(p<0.05). 5. CORT와 IL-4 측정에서 대조군과 SGH 투여군 모두 유의한 변화가 없었고, IL-$1{\beta}$ 측정에서 대조군에서는 유의하게 증가하였지만 SGH 투여군에서는 대조군에 비해서 유의한 변화가 없었다. 6. Hippocampus에서의 5-HT 측정에서 SGH 400 mg/kg/day 투여군은 대조군에 비해서 유의하게 증가하였다(p<0.05). Hypothalamus에서의 5-HT수준은 SGH 투여군 모두 대조군에 비해서 유의하게 증가하였다(SGH 100 p<0.05, SGH 400 p<0.01). 결 론: 이상의 결과로 SGH는 만성 스트레스를 가한 난소적출 흰쥐에서 항우울 효과가 있음을 알 수 있었고, HPA axis, immune system 보다 5-HT system에 작용하는 것으로 사료된다.
