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.

KJHST (Kejihongsarntang) is a modified oriental prescription that consists of five herbs such as Ginseng Radix rubra Koreana, Atractylodis Rhizoma, Zingiberis Rhiaoma, Cinnamomi Ramulus and Glycyrrhizae Radix. For the evaluation of antioxidant and staminal activities of KJHST (Kejihongsarntang), the study was done in comparison of Ginseng Radix rubra (GR). For the antioxidant study, KJHST inhibited hemolysis of erythrocyte and decolored the DPPH(2,2-diphenyl-1-picrylhydrazyl) free radical in a dose depenrlent manner more effectively than GR alone in vitro. KJHST and GR significantly suppressed the time course (1 hr∼6 hr)-level of MDA (malondialdehyde) following AAPH (2,2'-azo-bis-(2-amidino-propane) dihydrochloride) treatment in vivo as compared with control data with no statistical difference. From the evaluation of stamina by swimming test GR and KJHST significantly increased the swimming time in a time and dose dependent manner as compared with control data, while GR was more effective than KJHST in 2 weeks after treatment, though KJHST was more effective than GR at low dose (25 m/kg) 4 weeks after treatment. From the results it can be concluded GR and KJHST had antioxidant and staminal activities.

Background: Aerobic training can be defined as any physical exercise that increases the heart rate and enhances the body's intake of oxygen long enough to benefit the condition of body. Running, cycling, and swimming are examples of aerobic activities. This type of exercise optimises immune functions. Recently several experimental findings suggested that the regular swimming training increase immune response, but there have been very few reports which compare warm water exercise with cold water exercise in spleen lymphocytes. Methods: This study was designed to examine the effects of regular swimming training on Index, the number of lymphocytes, proliferative activity and production of reactive oxygen species (ROS) by splenocytes in BALB/c mice. Thirty six mice (6 week old) were performed 10 weeks of regular swimming training and they were divided into 6 groups according to the regular swimming training (CRG: control resting group, CEG: control exercise group, WRG: warm water trained resting group, WEG: warm water trained exercise group, CORG: cold water trained resting group, COEG: cold water exercise group). Analytical items were weight change, spleen index, the number of lymphocytes, proliferative activity and production of ROS. All data were expressed as mean and standard deviation by using SPSS package program (ver. 10.0). Results: The swimming training significantly decreased body weight, and increased spleen index, the number of lymphocytes and proliferative activity in the presence or absence of Con A and LPS added conditions. For the WRG and CORG, the quantity of ROS from splenocytes was higher than CRG, whereas, ROS by spleen lymphocytes was lower following 90 min acute exercise stress. Conclusion: These results suggested that the swimming training not only increases the number of lymphocytes but also increases proliferative activity by splenocytes in vitro.

$Nokyangbotang^{TM}$ (NYBT) is a kind of powerful food for health and have been drunk at a oral dose of 80 ml (99.5 mg) three times per day: It has not been well studied about the anti-fatigue and hepatoprotective activity. In this experiments, we evaluated pathophysiologically the effect of NYBT on swimming time in mouse and hepatoprotective activity in rats intoxicated with carbon-tetrachloride. NYBT was nontoxic in orally acute toxicity test ($LD_{50}$, 320 ml/60 kg): a nontoxic food in more four times of one-shoot dosage (80 ml) to human. Weight-loaded forced swimming test was carried out to measure the swimming time of mice with a 4% load of body weight in plastic cylinder (diameter $10{\;}cm{\;}{\times}{\;}height{\;}20{\;}cm$) on water bath at $25^{\circ}C$, and the anti-fatigue activity represented the ratio of swimming time of experimental group to that of control group. NYBT had dose-dependent anti-fatigue activity Mice administered NYBT at a dose of 320 ml/60 kg once daily for 5 days could swim about two times more than control. Hepatoprotective activities of NYBT were examined by the determination of malonedialdehyde (MDA) and pathological survey in liver and liver function test of rat intoxicated with $CCl_4$ at i.m. dose of 2 ml/kg once daily for 7days. NYBT decreased dose-dependently thiobarbituric acid reactive substance: Oral administration of NYBT at a dose of 20 ml/60 kg was $38.51{\;}{\pm}{\;}3.02$ nmol MDA/g of tissue, that of 80 ml/60 kg was $33.76{\;}{\pm}{\;} 1.84$ nmol MDA/g of tissue, and that of 320 ml/60 kg was $32.87{\;}{\pm}{\;}1.90$ nmol MDA/g of tissue as compared with control group ($43.61{\;}{\pm}{\;}2.85$ nmol MDA/g of tissue). All rats administered NYBT at a dose of 320 ml/60 kg were survival as compared with 40% survival of control animals, and GPT activity of rats administered NYBT at a dose of 80 ml/60 kg was decreased as compared with control. In histopathological survey, NYBT improved slightly the fatty changes of hepatocytes around centrilobular area. These results suggest that NYBT has anti-fatigue and hepatoprotective activity in rats and mice.

This study was conducted to investigate the attractant substances of different solvent fractions of mackerel and tuna viscera. Mackerel and tuna viscera were extracted with methanol and the resultant were fractionated with n-hexane, chloroform, ethyl acetate, n-butanol and water. The chemical compounds such as free amino acid, fatty acid, nucleotide related compounds contents were estimated for mackerel, tuna viscera and various fractions. These fractions were also subjected to attracting experiments in water tank to estimate attracting effects. The aqueous fractions of mackerel and tuna viscera showed the highest attraction effect on swimming crab. The major chemical compounds of the aqueous fractions were histidine, taurine, cysteine, glutamic acid, inosine monophosphate (IMP) and inosine (HxR) for mackerel and arginine, glutamic acid, aspartic aid, alanine, IMP and hypoxanthin (Hx). Results indicated that higher polarity compounds, such as amino acid and nucleotide related compounds have higher attraction activities than nonpolar substances such as neutral lipid.

Objectives: In this study the authors investigated effects of the ethanolic extract of Rhodjola Rosea(HKC) on fatigue and hypothalamic IEG expression in rat forced swimming(FS) model. Methods: Sprague-Dawley rats were administered HKC extract(25 mg/100g, p.o.) for 3 days prior to FS, some rats underwent 10 min FS and others exhaustive forced swimming(EFS). In addition, other rats were administered extract at different times after EFS over 3 consecutive days. Results: When HKC administered before 10 mins of FS, serum actate dehydrogenase(LDH) and creatine phosphokinase(CPK) activities were significantly lower than control group. When HKC administered prior to EFS, blood lactate was significantly lower versus control group. When HKC was administered after EFS, blood lactate(at 6 and 24 hours after EFS) were significantly lower and serum LDH, CPK activities(at 24 hours after EFS) were significantly lower versus control group. When HKC was administered after EFS, c-Fos positive neurons in hypothalamic periventricular area(PVA), medial part(mPVN) and anterior hypothalamic nucleus caudal part(AHC) were significantly lower at 24 hours after EFS than in control group. HSP-72 positive neuron numbers in hypothalamus were significantly lower at 24 hours after EFS than in control group. Finally, when HKC was administered prior to 10 mins FS, HIF-$1{\alpha}$ expression in the gastrocnemius muscle was significantly increased. Conclusions: These results suggest that HKC extract has an anti-fatigue effect, and it reduces neuronal cell stress responses induced by physical stress by having a beneficial effect on lactate metabolism.

As people's interest in the increase of individual leisure time and health grows, their interest in sports is also growing day by day to improve their standards of living. In the midst of the social changes, people's awareness of the disabled's sports activities is changing as well. However, the disabled's full access to public sports centers is restricted due to the shortage of facilities, area and available programs in public sports centers including community gymnasiums. In order to solve this problem, rehabilitation sports centers have been built as part of public sports centers, but the number of rehabilitation sports centers is still small. Besides, the disabled find themselves uncomfortable when using rehabilitation sports centers because most of them are outdated and too small in size. To make matters worse, sports centers for the use of the disabled only have a negative effect on the disabled's making inroads into society by hampering them from being a part of social unification. This study made a comparative analysis on the areal state of indoor gyms and swimming pools, which are the main areal factors of rehabilitation sports centers and public sports centers. Based on this analysis, this study aims to propose a sports center use plan for both the disabled and non-disabled. As a result, the total floor area ratios of indoor gyms for the disabled were found to be higher than those of public sports centers. This is because many indoor gyms for the disabled are not well equipped with resting areas, auxiliary or supporting areas. Regarding swimming pools for the disabled, their total floor area ratios and areas were found to be lower than those of public sports centers because, in many cases, these swimming pools are used for the rehabilitation of the disabled in rehabilitation sports centers. For this reason, swimming area for individual leisure activity or hobby is insufficient.

The methanolic extract of Hibiscus vitifolius flowers (HVE), was evaluated for neurophamacological activities by carrying out rota rod, locomotor activity and traction performance in mice and swim endurance activity in rats in different dosages (10, 30 and 100mg/kg body weight). HVE showed a significant effect on central nervous system by increasing the time taken for rota rod, traction performance and locomotor activity while swimming time was found to be decreased when compared to normal control animals. These results suggest that HVE possess significant anxiolytic and anti depressant activity which may be attributed to the presence of flavonoid in HVE.
