  • Objectives : Anxiety and depression are stress-related disorders. Their prevalence are increasing rapidly. Ginseng is the root of Panax ginseng C.A. Meyer (Araliaceae) which has been used for many centuries in asian region. Anxiolytic effect is one of the popular effects of ginseng. Several studies reported saponin fraction of ginseng, including ginsenoside, is a major ingredient of anxiolytic effect. In present study, we investigated anxiolytic-like and antidepressant-like effect of non-saponin fraction in mice. Material and Method : Mice were divided into five groups. Experimental groups were administered non-saponin fractions (25 mg/kg; nsp25, 50 mg/kg; nsp50, 100 mg/kg; nsp100) respectively once a day in the morning at 9am for 1 week. Then, we performed elevated plus-maze (EPM) test for investigating the anxiolytic-like effect and forced swimming test (FST) for investigating the antidepressant-like action. Results : Non-saponin fraction 50 mg/kg group increased frequency and time spent (p<0.05) in open arm on EPM test and decreased immobility time (p<0.05) on FST compared with control group. Conclusions : We suggest that non-saponin fraction has anxiolytic-like effect and antidepressant like effect in mice.

  • Objectives : This study investigated the effects of electroacupuncture on memory, depression, and plasma stress hormone levels in rats that were under immobilization stress. Materials and Methods : The immobilization-only group was given two hours of immobilization stress for 10 consecutive days. The immobilization and high frequency EA group was given two hours of immobilization stress simultaneously with high frequency (100Hz) electroacupuncture stimulation on the right ST-36 (Zusanli) for 10 consecutive days. We conducted the inhibitory avoidance and forced swimming tests to recognize whether immobilization stress and electroacupuncture have effects on memory and depression. We collected blood samples from the tail of each rat at 30, 60, 90, and 120-minute intervals during the immobilization stress and EA stimulation to measure plasma concentrations of ACTH, corticosterone, melatonin, and norepinephrine induced by immobilization stress and electroacupuncture. Results : There was a significant effect of high frequency on the increase in anamnesis based on the result of the inhibitory avoidance test, but there was no significant effect of decreasing depression based on the result of the forced swim test. Also, there was no significant effect on the response indicated by stress hormones. Conclusions : 1. High frequency electroacupuncture (100Hz) improved anamnesis in immobilization stress states under the inhibitory avoidance task. 2. High frequency electroacupuncture (100Hz) did not reduce depression induced by immobilization stress under the forced swimming test. 3. High frequency electroacupuncture (100Hz) did not decrease stress hormones through blood sampling.

  • A unicellular algae, Chlorella vulgaris(CV), was used as a biological response modifier. The effect of CV on forced swimming test and blood biochemical parameters related to fatigue was investigated. Blood urea nitrogen(BUN); creatine kinase(CK); lactic dehydrogenase(LDH); glucose(Glc); total protein(TP); and albumin were determined. CV was orally administered to mice in the range of 0.05 to 0.15 g/kg/day. A forced swimming test results on 3 and 7 day after administration of CV, showed that immobility time was decreased in the CV-administered group(0.15 g/kg). In addition, the contents of BUN in the blood serum were decreased in CV-fed group. The contents of CK and LDH were tended to decrease, but not statistically significant. The plasma Glc level was increased in CV-fed groups(0.05 and 0.1 g/kg) compared to control group. It had no effect on the elevation of TP and albumin level. The results indicate that CV could improve physical stamina.

  • Objectives: The main objective of this study was to evaluate the anti-depressant effects of pharmacopuncture using sumsu (Bufonis venenum). Methods: Animals were divided into three groups (control, sham, and experimental), with eight mice per group. The sham and the experimental groups were exposed to 2 hours of immobilization stress daily for 14 days. They were also injected with normal saline (sham) or subjected to pharmacopuncture with sumsu at the acupoints HT7, SP6, and GV20 (experimental). The depression or anxiety-like behaviors of the mice in each group were evaluated 1 day after treatment. Results: There was no difference in locomotor activity between the groups during the open-field test; i.e., all groups had normal motor function. However, the open-field and the forced-swimming tests revealed that depression and anxiety-like behaviors were decreased significantly in the group treated with sumsu pharmacopuncture. Conclusion: Sumsu pharmacopuncture attenuated depressive or anxiety-like behavior in mice stressed with chronic immobilization. These results suggest that sumsu pharmacopuncture has therapeutic potential for treating neuropsychiatric disorders such as anxiety or depression disorder.

  • Electroacupuncture(EA) is known to affect various autonomic functions such as blood pressure regulation, immune modulation and the improvement of disorders concerning autonomic functions. The aim of the present study was to establish whether EA has an immune-enhancing effect. ICR mice weighing 20 to 25g were divided into four groups: Group I(n=6), blank; Group II(n=6), control; Group III(Zusanli, n=6), low frequency-EA(10Hz of electrical stimulation), and Group IV(Zusanli, n=6), high frequency-EA (100Hz of electrical stimulation). For this study, we investigated expressions of spleen heat shock protein (HSP)70, HSP90 and secretions of cytokines. A Forced Swimming Test(FST) was performed as a model of activity test in mice. After three days of the FST, 10Hz EA($114.8{\pm}7.27s$) and 100Hz EA($147.5{\pm}1.29s$) immobility time significantly decreased compared with the control group($157.2{\pm}1.48s$). After seven days, 10Hz EA($124{\pm}1s$) and 100Hz EA($141{\pm}4.24s$) also significantly decreased immobility time compared with the control group($168{\pm}7.93s$). 10Hz EA and 100Hz EA increased the expression of HSP70 but did not change that of HSP90. 100Hz EA increased secretions of IL-6 and IL-12 compared with the control group however, 10Hz EA failed to change those of IL-6 and IL-12. The present results suggest that EA may be useful for down-regulated immune diseases.

  • The antidepressant effects of Cirsium japonicum compositae was investigated using open field test and forced swimming test. Total extract of Cirsium japonicum (CJ) was orally administered at dose of 20, 100, 300, 500 mg/kg bodyweight. Supplementation of CJ increased dose-dependently movement, rearing frequency and total turn angle in the center area of open field in mice. Treatment of Cirsium japonicum's extract (300 mg/kg, CJ) decreased immobile duration and increased mobile and strong mobile duration significantly; and it is comparable to that of imipramine and fluoxetine. These results indicate that CJ has antidepressant effect. Treatment of CJ did not induced any impairment in motor coordination and myorelaxation. These results indicate that the constituents or its complex of Cirsium japonicum could be a candidate of new antidepressant drug.

  • Objectives: In this research, the effect of Gyogam-dan (GGD) on depression and immunity were assessed in ovariectomized rats subjected to repetitive stress. GGD is the prescription consisting of Poria cocos and Cyperi Rhizoma. Methods: Ovariectomized rats were repeatedly stressed over a 2-week period. After GGD (100 or 400 mg/kg) were orally administered, Elevated Plus Maze (EPM) and forced swimming test (FST) were performed to evaluate depressive and anxiety response. As well, the change of corticosterone (CORT) and the change of interleukin-$1{\beta}$ (IL-$1{\beta}$) and interleukin-4 (IL-4) in blood serum and in brain were mesured. Results: 1. In the EPM, there were no statistically significant differences among the groups. 2. In the FST, immobility time significantly decreased in rats of each experiment group compared with the control group (p<0.01). 3. Serum CORT level were decreased in 400 mg GGD group (p<0.05). 4. On IL-$1{\beta}$ and IL-4 measurement in the serum and brain, there were not significant increase or decrease compared with the control group. Conclusions: These results suggest that GGD is effective to reduce depression-behavior in ovariectomized rats. However, GGD do not has significant efficacy to reduce anxiety-behavior in EPM test. Measurement of serum CORT level reveals significant decrease and it shows anti-depressant like effect. Results on immunity are not significant.

  • Objectives: We evaluated the anti-fatigue effects of Rh2-enriched Korean ginseng (Ginseng Rh2+) using a forced exercise-induced chronic fatigue mouse model. Methods: ICR male mice were subjected to running wheel for 1 h, 5 days/week during 4 weeks, and running velocity was gradually increased. Each running session was followed by oral administration of distilled water, Ginseng Rh2+ (150 or 300 mg/kg), or N-acetyl-L-cysteine (NAC, 100 mg/kg) 1 h later. The exercise tolerance and forced swimming test were performed to evaluate the fatigue condition. Results: Chronic forced exercise reduced the physical activity, as evidenced by the behavioral tests, which were notably ameliorated by Ginseng Rh2+ treatment. Ginseng Rh2+ treatment also attenuated the alterations of energy metabolism and oxidative stress in skeletal muscle tissues and/or sera, including malondialdehyde (MDA), lactate concentration and its related factors (lactate dehydrogenase, blood urea nitrogen, and glucose levels). Conclusion: These findings strongly suggest that Ginseng Rh2+ exerts a potent anti-fatigue effect through modulation of energy metabolism and oxidative response.
