Objectives In this study, we analyzed the effect of Dioscoreae Rhizoma on exercise practice ability and blood fatigue variable factor in the forced swimming test. Methods Male mice were divided into four group. Mice were administrated with saline, Discorae Rhizoma extracted by water (DRW), Discorae Rhizoma extracted by 30% ethanol (DRE), red ginseng (RG), orally once per day, for 1 week. Exercise performance was evaluated by exhaustive swimming time and weights. Glycogen contents of liver and soleus muscle were measured at the end of the experiment. In addition, the biochemical parameters such as asparate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen, creatine, lactate dehydrogenase (LDH), ammonia, triglycerides (TG), total cholesterol (TC) and free fatty acid (FFA) were analyzed. Results Both DRW and DRE showed an improvement of swimming endurance compared with control group. Levels of ALT, ammonia, TG, TC and FFA were significantly decreased in both DRW and DRE compared with control group. Levels of AST, Creatine were significantly reduced in DRE group compared with control group. Moreover LDH showed only a tendency to increase in the DRW and DRE groups. Conclusions In summary, the present study showed that Dioscoreae Rhizoma improved in physical fatigue and exercise practice ability and DRE improved the superior than those of DRW.

The aim of this was to evaluate the effects of Rhus Verniciflua Stoke (RVS) extract powder on the endurance capacity for the forced swimming mice. Thirty mice were divided into 3 groups including negative control, 250 (RVS-250) and 500 (RVS-500) mg/kg RVS extract powder groups for 4-times swimming exercises. The swimming times to exhaustion in RVS-250 and RVS-500 mice were prolonged 1.6- and 2.0-fold at 4 weeks compared with negative control mice, respectively. Blood biochemical parameters for AST, ALT, T-CHO and TG were not significantly different between RVS fed or negative control mice. However, blood concentration of creatinine was significantly increased in RVS-250 mice, but not in RVS-500 mice. During the longer swimming exercise in RVS group, blood glucose and lactate levels were significantly decreased, but free fatty acid not changed. And also LDH levels were significantly decreased in RVS groups compared to negative control mice. Hepatic lipid peroxidation was not affected by RVS, but SOD and catalase activity were significantly increased in RVS groups. Interestingly, the levels of testosterone and free testosterone were significantly increased in RVS groups before swimming exercise, but they were not significantly changed among groups after swimming exercise. The present results suggest that RVS extract powders may enhance swimming exercise performance by recovering the exercise-fatigue via reduction of blood LDH activity and by burning blood glucose as an energy source. These results imply that RVS-produced testosterone may act as an energy buster to enhance physical activity.

A series of 5-alkoxy-tetrazolo[1,5-a]quinolines were synthesized to evaluate their anticonvulsant and antidepressant effects. Anticonvulsant effects and neurotoxicity of the compounds when injected intraperitoneally to mice were determined by a maximal electroshock (MES) test and a rotarod test, respectively. Only three of the synthesized compounds (4a, 4b, 4c) displayed anticonvulsant activity at a dose of 300 mg/kg. Most of the compounds significantly reduced immobility times during the forced swimming test (FST) at a dose of 100 mg/kg, indicative of antidepressant activity. Among the compounds, 5-(2-fluorobenzyloxy)tetrazolo[1,5-a]quinoline (4k) reduced immobility time by 66.85% at 30 mg/kg compared with the same dose of Fluoxetine, which reduced immobility time by 52.30%. According to the results of the 5-Hydroxytryptophan induced head-twitch test and yohimbine toxicity potentiation test, the noradrenergic system seems not to be involved in the antidepressant-like effect of compound 4k while the serotonergic system seems a little to be involved.

Objectives : In order to investigate the antidepressant effects of Forsythiae Fructus(FF), we performed the Forced Swimming Test(FST). Also the expressions of corticotropin-releasing factor (CRF), c-Fos and tyrosine hydroxylase(TH) were measured by immunohistochemical method at paraventricular nucleus(PVN), ventral tegmental area(VTA) and locus coeruleus(LC). Methods : Spraque-Dawley rats were administered FF extract(100 mg/kg, 400 mg/kg) intragastrically three times prior to the FST. Results : The duration of immobility in the FST was significantly decreased in the FF 100 mg/kg, 400 mg/kg groups(p<0.05). The expression of CRF was significantly reduced in the FF 100 mg/kg and 400 mg/kg groups(p<0.001). c-Fos expression was significantly decreased at PVN in the FF 100 mg/kg group(p=0.069). TH expression at VTA was significantly increased in the FF 100 mg/kg and 400 mg/kg groups(p<0.05). TH expression at LC was not significantly changed(p=0.346). Conclusion : According to the results, it can be suggested that Forsythiae Fructus has antidepressant effect via the decreased immobility through the reduction of CRF and c-Fos expression at PVN.

Inflammation has been linked to various diseases. Especially, fatigue is a frequent symptom in several inflammatory disorders. Therefore, blocking inflammatory process is effective in fatigue. We investigated whether Denmark porcine placenta (DPP) alleviates fatigue by inhibiting inflammatory reaction using forced swimming test (FST) animal model and RAW264.7 cells. In FST-induced fatigue animal model, the mice which received the DPP for 21 days showed decreases of interleukin $(IL)-1{\beta}$ and IL-6 serum levels. Furthermore, our data revealed that lipopolysaccharide (LPS)-induced $IL-1{\beta}$, IL-6, and tumor necrosis $factor-{\alpha}$ secretion were markedly inhibited by DPP in RAW264.7 cells without inducing cytotoxicity. LPS-enhanced nitric oxide secretion and inducible nitric oxide synthase expression were inhibited by DPP. The present study also figured out that these effects of DPP were mediated by blockade of caspase-1 and nuclear $factor-{\kappa}B$ activation. Taken together, our results indicated that DPP could be alleviating fatigue as candidate of anti-inflammatory agent.

Objective : This study was designed to assess the protective effects of Chengwhabosimtang on the animal model of depression, chronic mild stress(CMS). Method : Male Sprague-Dawley rats Were used for this experiment. The subjects Were divided into 3 groups (1. CMS-drug: Chengwhabosimtang administered during CMS treatment, 2. CMS-vehicle: water administered, 3. normal ). After 4 weeks of CMS treatment they were executed Forced swimming test(FST) and Elevated plus maze. Tyrosine hydroxylase(TH) in ventral tegmental area(VTA) and c-Fos in paraventricular nucleus(PVN) were measured. Result : 1. In FST, CMS-drug group showed significantly decreased immobility behavior. 2. CMS-drug group showed no significantly lower TH level in VTA than CMS-vehicle group. 3. CMS-drug group showed significantly less c-Fos expressed cell bodies in PVN than CMS-vehicle group. 4. In Elevated plus maze, CMS-drug group showed no significantly anxiety. Conclusion : These results suggest that Chengwhabosimtang may have protective antidepressant effects in CMS model rats. And these effects could be explained by the elevated stress-copying behaviors which are related with PVN of hypothalamus and dopaminergic neurons in VTA.
