Objectives : Jakyakgamcho-tang has been used as analgesic and spasmolytic for muscle pain. It has reported to anti-diabetes, anti-inflammation, and neuro-protective effects. A clinical study of muscle fatigue and pain improvement effect of Jakyakgamcho-tang has been reported with increasing frequency of clinical use. However, the anti-fatigue effect of Jakyakgamcho-tang in animal model has not been studied. In this study, we compared anti-physical fatigue effects of water and 30% ethanol extract of Jakyakgamcho-tang. Methods : The amounts of components contained in water and 30% ethanol extract of Jakyakgamcho-tang were compared by ultra-performance liquid chromatography. Anti-physical fatigue effects were evaluated using weight-loaded forced swimming test. We also investigated the effects of Jakyakgamcho-tang on the change of fatigue parameters by blood biochemical analysis. Results : The relative amount of components of Jakyakgamcho-tang were about 19-53% higher in the 30% ethanol extract than in the water extract. In the swimming test, 30% ethanol extract showed a significantly greater anti-fatigue effects than conventional water extract of Jakyakgamcho-tang. The 30% ethanol extract of Jakyakgamcho-tang improved the exhausted swimming time (54%), and serum lactate dehydrogenase (48%) and lactic acid (60%) levels compared with water extract of Jakyakgamcho-tang. Conclusions : These results showed that differences in the amounts of components by different extraction were associated with differences of anti-fatigue effect of Jakyakgamcho-tang. Thus, the 30% ethanol extraction method could be applied to dose-reducing formulations of traditional herbal medicines.

KH-red ginseng/chlorella (KH-RG/C) is the mixed material of the Korean red ginseng powder (Panax ginseng, 75%) and extract of Chlorella vulgaris (25%). To evaluate the effects of KH-RG/C on endurance capacity and immune regulation, the forced swimming test (FST) was conducted. The immobility time in the FST was significantly decreased in KH-RG/C treated group compared with the DW-treated group at the 3 and 10 days, respectively. In the analysis of the blood biochemical parameters, KH-RG/C treatment significantly increased the glucose level. However, the lactic dehydrogenase level decreased. Although KH-RG/C increased aspartate aminotransferase, it was not different significantly. And KH-RG/C had no affects in the alanine aminotransferase, and blood urea nitrogen levels. In splenocytes and macrophages, KH-RG/C also did not affect the interleukin (IL)-2, IL-4, and IL-12 production. These results suggest that KH-RG/C may influence to immune regulation through increasing the physical endurance capacity without effect in activation of immune cells.

Objectives : For the purpose of verifying the anti-depressant effect of Paeoniae Radix Rubra(PR), the expression of corticotropin-releasing factor(CRF), c-Fos and tyrosine hydroxylase(TH) was evaluated after performing the Forced Swimming Test(FST). Methods : Spraque-Dawley rats were ingested PR extract(100mg/kg, 400mg/kg, p.o.) for 3 times prior to FST. And the expression of corticotropin-releasing factor(CRF), c-Fos in the paraventricular nucleus(PVN) and tyrosine hydroxylase(TH) in the locus coelureus(LC) and ventral tegmental area(VTA) was measured immunohistochemically after FST. Results : The duration of immobility was significantly decreased in PR 100mg/kg Group and PR 400mg/kg Group, in comparison with the control group (p<0.001). The expression of CRF in the PVN was significantly decreased in PR 400mg/kg Group in comparison of the control group (p<0.05). The expression of c-Fos in the PVN was rather significantly increased in PR 100mg/kg Group in comparison with the control group, while almost no change was demonstrated in PR 400mg/kg Group. The expression of TH was significantly decreased in VTA in comparison with the control group (p<0.05), but the number of expression cells in LC was slightly decreased in case of PR 100mg/kg group while it was increased in case of PR 400mg/kg Group. Conclusion : Judging from the result of the aforementioned tests, Paeoniae Radix Rubra has decreased immobility. In addition, it has also decreased the expression of CRF and the expression of TH in VTA, while the expression of c-Fos and of TH in LC has no significance. Therefore, it is believed that Paeoniae Radix Rubra has an anti-depressant effect by decreased immobility through the reduced expression of CRF and TH in VTA.

Depression is a sort of mental disorder which is very common. To treat depression, many drugs such as TCA, MAOI are developed and used. But they have a lot of side effects, so it needs to develop drugs without side effects or with less side effects. Herbal medicines have been used to treat diseases not only physical but also mental and have less side effects. therefore, it has been thoght the need to develop herbal medicine with antidepressant effect. The purpose of this study was to reseach antidepressant effect and influence on monoamines of chunwangboshimdan thought to have antidepressant according to ancient medical book- donguibogam- and recent reports. We used 'forced swimming test(FST)' to know antidepressant effect of chunwangboshimdan and HPLC to check the influence on monoamines and their metabolites(norepinephrine, dopamine, DOPAC, HVA, serotonin, 5-HIAA) of chunwangboshimdan after divided into cerebral cortex, striatum, hypothalamus and hippocampus. The results were obtained as follows: In the study of antidepressant effect by 'forced swimming test(FST)'method, chunwang boshimdan had a significant antidepressant effect. In the study of influence on monoamines by HPLC, chunwangboshimdan mainly increased dopamine among monoamines and their metabolites(norepinephrine, dopamine, DOPAC, HVA, serotonin, 5-HIAA) significantly in 4 parts of rat's brain above-mentioned. Calculated by turnover ratio formulae of monoamine, chunwangboshimdan has more results than Imipramine. These results suggest that chunwangboshimdan has antidepressant effect that is related with the increase of monoamines by suppressing their metabolism as its mechanism.

The purpose of the present study was to examine the effect of Lycii Radicis Cortex (LRC) and betaine (BT) on immobility and neurochemical change in the forced swimming test (FST) in the rat. LRC, BT or fluoxentine was administered intraperitoneally to Sprague-Dawley rats three times (1, 5 and 23.5 h) before the FST. To investigate antidepressant-like effect, serotonin (5-HT) and norepinephrine (NE) were examined in the hippocampus and hypothalamus of rats. LRC (100 mg/kg) and BT (30, 100 mg/kg) significantly decreased the immobility time in the FST. LRC (100 mg/kg) significantly increased both 5-HT and NE levels in the hypothalamus of rats exposed to FST. BT (100 mg/kg) significantly increased 5-HT levels in the hypothalamus and hippocampus of rats. Taken together, these results demonstrated that improvement in the behavioral changes after LRC and BT administration may be mediated by elevation of 5-HT level in the hypothalamus and hippocampus, indicating a possible antidepressant-like activity. The present results suggest that the efficacy of LRC and BT in an animal model of depression may provide anti-depressant effects in human, which remains to be determined.

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.

Objectives : The effects of Extraction after Mixture of Bupleuri Radix and Lycii Radicis Cortex on the change of the HPA-Axis system and the Catecholamic system was investigated. Methods : After performing the Forced Swimming Test(FST), the expressions of corticotropin releasing factor(CRF), c-Fos in the paraventricular nucleus(PVN), and tyrosine hydroxylase(TH) in the ventral tegmental area(VTA) and locus coeruleus(LC) were measured by immunohistochemical method. Results : The duration of immobility in FST was significantly decreased in A 100(Extraction after Mixture of Bupleuri Radix and Lycii Radicis Cortex, 100mg/kg) and A 400(Extraction after Mixture of Bupleuri Radix and Lycii Radicis Cortex, 400mg/kg)(p<0.001). The expression of CRF in the PVN was shown the tendency to reduce in A100 and A400. The expression of c-Fos in the PVN was shown the tendency to reduce in A100 and A400. The expression of TH in the VTA was shown the tendency to reduce mildly in A100 and A400. The expression of TH in the LC was significantly reduced in A400(p<0.001). And the dose dependent reduction tendency was shown, respectively. Conclusions : According to the results above mentioned, the immobility, c-Fos and CRF expression was reduced at lower dose and was increased at higher dose. Therefore there is contradictory effects on the HPA Axis system in accordance with the dose. But in the effects on the catecholaminergic system, it significantly reduced the expression of TH in the LC. It was validated that the effect on the catecholaminergic system was ruled by Bupleuri Radix rather than Lycii Radicis Cortex via mainly the noradernergic system.
