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.

We tested whether ginsenosides $Rg_3$-standardized ginseng extract (RGE) has anti-stress effects in restraint-stressed animals. RGE increased time spent in the open arms and open arm entries in the elevated plus-maze test. In addition, RGE blocked the reduction of center zone distance and stereotypes behaviors in the open-field test. RGE also increased head dips in stressed mice, indicating anxiolytic-like effects. Stress decreased movement distance and duration, burrowing, and rearing frequency but increased face washing and grooming. RGE significantly reversed burrowing and rearing activity in stressed mice. In addition, we measured sleep architecture in restraint stressed rats using EEG recorder. Stress increased rapid eye movement (REM) sleep, but total sleep and non-rapid eye movement (NREM) sleep were not changed. RGE did not affect sleep architecture in stressed rats. These behavioral experiments suggest that RGE has anti-stress effects in restraint-stressed animal models.

The effects of anti-stress chrysanthemum flower (ASCF) extract drink (ASCF-0.1% and ASCF-0.5% concentrations) were tested for the anti-stress action. ICR male mice (20$\pm$2 g) were fed with basic experimental diets and given free access to water containing these ingredients for 18 days. Psychological stress/sociopsychologcal stress exposed by foot-shock for 1 hour for 3 days. Both ASCF-0.1 and ASCF-0.5 groups in the sociopsychological stress resulted in a significant decrease of 28.1% and 27.3% in plasma corticosterone (CS) secretion compared with psychological stress (control group). Noradrenaline (NA) secretions in the brain were significantly increased 49.7% and 53.9%, respectively, in ASCF-0.1 and ASCF-0.5 groups compared with control group. MHPG-SO4 (3-Methoxy-4-hydroxyphenylethy-leneglycol sulfate) levels in the brain resulted in a marked decreases of 12.9% and 16.6%, respectively in ASCF-0.1 and ASCF-0.5 groups. NA/MHPG-SO4 ratios in the brain of ASCF-0.1 and ASCF-0.5 groups resulted in a significantly increase of 71.3% and 81.0%, respectively, compared with control group. These results suggest that anti-stress chrysanthemum flower (ASCF) drink can effectively ridded the sociopsychological stress.

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.

Oxidative stress and overproduction of free radicals have been reported to be a major pathological hallmark of neurodegenerative diseases. Samultang has been known as a beneficial agent to treat liver disease and cardiovascular diseases. However, the anti-oxidant activities and neuro-protective effects of Samultang against oxidative stress still have not been evaluated yet. The aim of the present study was to investigate the anti-oxidant and protective effects of Samultang and its four herbal plants, Paeonia lactiflora (PL), Ligusticum striatum (LS), Rehmannia glutinosa (RG), and Angelica gigas (AG), in vitro system and in SH-SY5Y neuronal cells. The extracts of Samultang strongly increased the radical scavenging activities of 1,1-diphenyl-2-picrylhydrazyl (DPPH), hydroxyl radical (${\cdot}OH$), and nitric oxide (NO) in a concentration-dependent manner. Furthermore, we investigated the protective effects of Samultang on cellular damage against oxidative stress induced by hydrogen peroxide ($H_2O_2$) in SH-SY5Y cells. Treatment with Samultang alleviated the oxidative stress from $H_2O_2$ by increasing the cell viability and decreasing the intracellular reactive oxygen species levels. Based on these results, we further investigated the radical scavenging effects of PL, LS, RG, and AG. In our results, PL had the highest DPPH, ${\cdot}OH$, and NO radical scavenging activities. Thus, PL has a crucial role in Samultang, which has anti-oxidative and neuro-protective effects. The present research suggests that Samultang and PL have protective roles against oxidative stress from $H_2O_2$-induced neuronal cell death.

스트레스 반응은 위급 상황에서만 활성화 되는 것이 아니라 우리 주변을 둘러싼 모든 사회적, 물리적 환경에 의해 끊임없이 기인된다. 예를 들어 소음, 강한 빛과 열, 주거의 공간 등과 같은 물리적 환경과 타인과의 관계, 부당한 대우, 규칙, 형식과 같은 사회적 관계 이 그것이다. 고려 인삼은 항스트레스 작용을 한다고 알려져 있으나 현재까지 대부분의 연구는 인삼 엑기스 또는 총 사포닌을 투여 시 나타나는 물리화학적인 척도 (수영 시간, 뜨거움에 대한 반응, 포도당 및호르몬 수준 등)를 측정하였으며 뇌에서 ginsenoside의 기능연구는 매우 미흡한 수준이다. 특히 신호전달, 전사체 (transcriptome),proteomics, system biology와 같은 분자생물학적인 방법을 이용한 기전 연구는 전혀 수행된 바 없다. 따라서 인삼의 항 스트레스 반응 기전을 이해하기 위해서는 인삼투여 후 뇌에서 나타나는 분자적 변화에 대한 연구가 앞으로 요구된다. 또한 microarray 등의 분자생물학적 기법을 이용하여 인삼 투여에 의해 반응하는 유전자를 발굴함으로써 이러한 인자들이 인삼 효능 시험 등에 지표로 응용될 수 있을것이다.
