Depression is a very difficult disease to be cured because several nervous systems are involved. In the present study, we evaluated the effects of Keum-Ryung-Ja-San (KRJS), a traditional herbal prescription, on depressive behaviors in mice using the forced swimming test. KRJS was given 1 h prior to the forced swimming test (50, 100, 200, an400 mg/kg, p.o.). The duration of immobility time in the forced swimming test was significantly reduced by KRJS treatment (200 mg/kg, P<0.05) and similar effects were observed with a classical antidepressant, imipramine (15 mg/kg, i.p.). With subchronic administrations of KRJS and its constituents at several doses for 1 week, a decreased duration of immobility time was observed with KRJS and Corydalis ternata (200 mg/kg, p.o. P<0.05). These results suggest that KRJS may have antidedpressive activities and CT may contribute to the antidepressive activity of KRJS.

Objectives : Ganoderma Lucidum has been used in traditional oriental medicine to treat various conditions including chronic fatigue and cough. This experimental study was designed to investigate the effects of yeast-fermented Ganoderma Lucidum extract on the fatigue of rats elicited by forced swimming. Materials and methods : The rat subjects were divided into 4 groups: normal group, control group administered with 0.9% normal saline, experimental I(Exp I) group administered with yeast-fermented Ganoderma lucidum extract and experimental II(Exp II) group administered with Ganoderma lucidum extract for 4 weeks. All the serum samples collected by heart puncture were used to measure biochemical factors such as glucose, lactate, lactate dehydrogenase(LDH), creatine kinase(CK), inorganic phosphorus, ammonia, total cholesterol(TC), triglycerides(TG), high-density lipoprotein(HDL), low-density lipoprotein(LDL), aspartate transaminase(AST), alanine transaminase(ALT). Results : 1. Weight change and swimming time were not significantly different in the experimental groups as compared with control group. 2. Lactate was significantly decreased in the experimental groups as compared with control group. Inorganic phosphorus was also significantly decreased in the Exp I group as compared with control group(p<0.05). 3. Serum lipid concentration was not significantly different in the experimental groups as compared with control group. 4. AST and ALT were significantly decrease in the experimental groups as compared with control group. Conclusions : Yeast-fermented Ganoderma lucidum in forced swimming rats would appear to reduce fatigue-related factors, AST, ALT of serum and promote anti-fatigue effect.

Objectives: Cultivated wild ginseng (cWG), called SanYangSanSam, has been used clinically in patients with chronic fatigue in Korea. Little is known about effects of the ginseng distilled (volatile) components produced during evaporizaiton. Recently, we first identified one major component from cWG distilled extract, panaxydol, by using mass spectrometry. However, functional properties of cWG distilled extract and panaxydol remains elusive. Therefore, the present study evaluated the effect of cWG distilled extract or panaxydol on exercise-induced fatigue in rats. Methods: Fatigue was induced by forced swimming and the immobility time was analyzed in male Sprague-Dawley rats. The animals received intraperitoneally either vehicle, cWG distilled extract, or panaxydol 10 min prior to beginning of the forced swimming test (FST) once daily for 5 days. After the FST on day 5, we also analyzed fatigue-related biochemical levels including blood urea nitrogen (BUN), lactate acid (LAC), and lactate dehydrogenase (LDH) in serum and levels of glycogen in liver and soleus muscle. Results: The forced swimming time in cWG distilled extract (0.6 mL/kg)-treated group was significantly longer than that of control group on day 4 and 5. Panaxydol (0.1 and 0.25 mg/kg)-treated groups showed significantly enhanced performance in the forced swimming, compared to control. In addition, a significant decrease in serum LDH level was found in panaxydol-treated group, while there were no alternations in levels of serum BUN and LAC and glycogen in liver or soleus muscle. Conclusion: The present study demonstrated cWG distilled extract and its active component panaxydol have a function of anti-fatigue.

Effects of two types of formula designed for commercial product on forced-swimming capacity and related biochemical parameters of Sprague-Dawley rats were evaluated. Treatment groups were fed diet supplemented with 4.56% formula A (EFA: exercise-trained and formula A-supplemented group) or B (EFB: exercise-trained and formula B-supplemented group) for 4 weeks. All groups were regularly trained twice a week to be accustomed to swimming. After 4 weeks, each group was divided into two subgroups: 90 min swimming (90-min subgroups) and swimming until exhaustion (all-out subgroups). Serum was collected, and skeletal muscles were dissected out after swimming. Forced-swimming time until exhaustion was significantly longer (p<0.05) in EFA and EFB groups than that of exercised control group. Among 90-min subgroups, serum ammonia level of EFB group was significantly lower than that of exercised control group (p<0.05). Among all-out subgroups, serum lactate levels were not significantly different among exercised control and treatment groups, whereas serum-free fatty acid levels of EFA and EFB groups were significantly lower than that of exercised control group (p<0.05). In conclusion, EFA and EFB groups enhanced forced swimming capacity of rats by increasing fat utilization and delaying accumulation of serum fatigue factor.
