  • This study was performed to investigate the anxiolytic-like effects Panax ginseng in mice using the elevated plus-maze model. Furthermore, the anxiolytic-like effects of Panax ginseng were compared to a known active anxiolytic drug, diazepam. Ginseng total saponin (GTS, 100 mg/kg) from red ginseng (RG), sun ginseng (SG) total extract (50 mg/kg), butanol fraction of SG(25 and 50 mg/kg) and ginsenosides ($Rb_1,\;Rg_1,\;and\;Rg_5$ and Rk mixture) significantly increased the number of open arm entries and the time spent on the open arm, compared with that of control. However, Red ginseng (RG) total extract (l00 mg/kg), GTS (25, 50 mg/kg), SG total extract (25 mg/kg) and ginsenosides ($Rg_{3}-R\;and\;Rg_{3}-S$) did not increase the number of open arm entries and the time spent on the open arm. On the other hand, butanol fraction of RG (l00 mg/kg), total extract of SG (50 mg/kg), butanol fraction of SG (50 mg/kg), ginsenosides ($Rb_{1},\;and\;Rg_{5}$ and Rk mixture) decreased the locomotor activity, in a similar fashion to diazepam. These data support that ginseng has the anxiolytic-like effects and the anxiolytic potential of SG was stronger than that of RG. Ginsenosides $Rb_{1},\;Rg_{1},\;and\;Rg_{5}$ and Rk mixture play important role on the anxiolytic-like effects of Panax ginseng. We provide evidence that ginseng and some ginsenosides may be useful for the treatment of anxiety.

  • Cyclic nucleotide phosphodiesterases (PDEs) represent the unique enzymatic system degrddinf cAMP and cGMP which play a major role in the regulation of cell physiology. To investigate a possible molecular mechanism of ginsenosides, their activities were evaluated on PDEs which are recently described is new therapeutic targets. PDEs are classified into 7 families according to their genes (PDEI to PDE7) and are differently distributed in tissues. The IC50 values of ginsenosides were determined on PDEI to PDE 5 chromatographically isolatetl from bovine aorta. The results show that total ginseng saponin extract preferentially inhibits PDE 1 and PDE4 at concentrations nearby 200 ug/ml. Protopanaxadiol (PPD) fraction acts preferentially on PDE4 with and IC50 value of 100 nlml and inhibits also PDEI and PDE5 at 14 to 2 fold higher concentrations, respectively. Protopanaxatriol (PPT) fraction preferentially inhibits PDE 1 with and IC50 value of 170 ug/ml. Compound Rgl, originated from PPT fraction, and RC3 (5) represent the most active compounds towards PDE 1 with IC50 values around 80 UM. However Rg3 (R), epimer of Rgl (5) has no effect on the various PDEs tested, excepted on PDE3 rich is sligthly sensitive Compound Rbl, originated from PPD, acts on both PDEI and PDE4. It if two fold less active than Rgl and Rg3 (5) on PDEI. Taken together, these results mainly suggest that PDEI and PDE4 inhibitions could be a molecular mechanism which would participate in ginsenoside mechanisms, especially the effect of PPD on blood vessel and on CNS.

  • The present study was undertaken to investigate an effect of ginseng butanol fraction(total saponin) on the hepatic ethanol metabolism, we used experimental animals for the subject of study. When, in case of ADH and MEOS, ginseng butanol fraction was added, enzyme activity was increased in a small dose, and on the contrary, in a large dose, showed inhibitory effect. in catalase, the activity showed no significant effect by adding ginseng butanol fraction. In the light of kinetic aspect, when, in reaction mixture, ethanol and ginseng butanol fraction were concurrently added and reacted, Km value of ADH and MEOS was decreased. After pretreated with ginseng butanol fraction and inducement of acute toxic state by ethanol, the activities of ADH and MEOS were increased to an extent of about 25% compared to controls. But catalase activity was not significantly affected. In case that ginseng butanol fraction was given to mice fed with 5% ethanol instead of water for 60 days, the activities of ADH and MEOS were increased about 20% to 50% compared to ethanol-treated group. On the contrary, catalase activity was not affected. But blood concentrations of ethanol were decreased due to ginseng butanol fraction treatment. All these observations suggested that reduction of ethanol blood concentration should be dependent upon increased activities of ADH and MEOS. Thereby it suggests the recovery from alcohol intoxication can be prompted by treatment with ginseng.

  • Superoxide dismutase (SOD) and catalase constitute the first coordinated unit of defense against reactive oxygen species. Here, we examined the effect of ginseng saponins on the induction of SOD and catalase gene expression. To explore this possibility, the upstream regulatory promoter region of Cu/Zn superoxide dismutase (SODI) and catalase genes were linked to the chloramphenicol acetyl-transferase (CATI structural gene and introduced into human hepatoma HepG2 cells. Total saponin and panaxatriol did not activate the transcription of SODI and catalase genes but panaxadiol increased the transcription of these genes about 2-3 fold. Among the Panaxadiol ginsenosides, the Rb2 subtraction appeared to is a major induce of SODI and catalase genes. Using the deletion analyses and mobility shift assays, we showed that the 5051 gene was greatly activated by ginsenoside Rba through transcription factor AP2 binding sites and its induction. We also examined the effect of the content ratio of panaxadiol extracted from various compartment of ginseng on the transcription of 5031 gene. Saponin extract that contains 2.6-fold more PD than PT from the fine root Increased the SODI induction about 3-fold. These results suggest that the panaxadiol fraction and its ginsenosides could induce the antioxidant enzymes, which are important for maintaining cell viability by lowering level of oxygen radical generated from intracellular metabolism.

  • 사포닌 함량과 PD계 사포닌과 PT계 사포닌의 조성 비율이 상이한 사포닌 분획물 TS-1, TS-2, TS-3 즉 주종 ginsenoside의 총함량$(G-Rb_1,\;-Rb_2,\;-Rc,\;-Rd,\;G-Re,\;-Rf,\;-Rg_1)$은 각각 $41\%,40\%,62\%$이고, PD계 사포닌과 PT계 사포닌의 함유 조성비율(PD/PT)이 각각 1.55, 2.25, 2.61인 시료를 6년근 홍삼으로부터 추출 제조하여, 생체외 실험으로 음경해면체 절편에 대한 이완반응과 생체내 실험으로 사포닌분획물 투여에 따른 음경 해면체내압의 변화에 미치는 효과를 조사하였다. PHE에 의해 수축된 음경해면체 절편에 대한 이완 반응은 홍삼 사포닌은 각각 농도 의존적 이완작용을 보였으며, 음경 해면체평활근의 이완작용에 있어 각 분획물의 $ED_{50}$은 TS-1이 1.68, TS-2, 1.97, TS-3, 2.29 mg/ml서 TS-1이 가장 의의있게 낮았다. 이러한 홍삼 사포닌 분획물의 이완효과 기전은 음경 해면체평활근에 NO나 칼슘 및 칼륨 통로 등에 영향을 미쳐 복합적인 이완작용을 보이는 것으로 사료되었다. 흰쥐를 이용한 생체내 실험으로 홍삼 사포닌 투여에 따른 음경해면체내압의 변화 조사에서 각 사포닌 분획물은 농도의존적으로 해면체내압의 증가를 야기시켰다. 이들 해면체내압의 증가 정도는 TS-1이 가장 강하였고,TS-2,TS-3 순이었다. 이상의 결과로부터 홍삼의 사포닌 분획물은 음경해면체평활근의 이완작용과 내압의 증가에 영향을 미쳐 음경발기의 상승을 야기시키는 효과가 있으며 그 효과는 그 함유 조성에 따라 차별성이 있다는 것이 확인되었으므로 금후 주요 활성성분의 구명이 요망되고 있다.

  • Background: Ginseng total saponin (GTS) contains various ginsenosides. These ginsenosides are widely used for treating cardiovascular diseases in Asian communities. The aim of this study was to study the effects of GTS on cardiac injury after global ischemia and reperfusion (I/R) in isolated guinea pig hearts. Methods: Animals were subjected to normothermic ischemia for 60 minutes, followed by 120 minutes of reperfusion. GTS significantly increased aortic flow, coronary flow, and cardiac output. Moreover, GTS significantly increased left ventricular systolic pressure and the maximal rate of contraction ($+dP/dt_{max}$) and relaxation ($-dP/dt_{max}$). In addition, GTS has been shown to ameliorate electrocardiographic changes such as the QRS complex, QT interval, and RR interval. Results: GTS significantly suppressed the biochemical parameters (i.e., lactate dehydrogenase, creatine kinase-MB fraction, and cardiac troponin I levels) and normalized the oxidative stress markers (i.e., malondialdehyde, glutathione, and nitrite). In addition, GTS also markedly inhibits the expression of interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6, and nuclear factor-${\kappa}B$, and improves the expression of IL-10 in cardiac tissue. Conclusion: These data indicate that GTS mitigates myocardial damage by modulating the biochemical and oxidative stress related to cardiac I/R injury.

  • The present study was undertaken to elucidate the effects of ginseng components on rat lens aldose reductase activity. Ginseng total saponin (GTS) exhibited inhibitory activities on rat lens aldose reductase in a dose-dependent manner. Among ginsenosides, Rf and Rgl showed potent inhibitory activities on rat lens aldose reductase. Lipid soluble fraction also inhibited rat lens aldose reductase activities. These data suggest that ginseng components inhibit rat lens aldose reductase activity in vitro.
