신성고혈압백서모델인 one-kidney, one-clip Goldblatt 고혈압백서에서 혈압과 NO생성에 미치는 고려홍삼 사포닌과 비사포닌의 영향을 규명하고자, 무마취 무제한상태에서 혈압을 측정하고, 혈중 NO와 NO합성효노에 대한 활성 및 단백량을 실시한 결과이다. 고려홍삼 사포닌은 정상혈압백서 및 신성고혈압백서에서 모두 혈압을 강하시키는 효과가 현저하였는데 혈압강하는 초기 2-4분 동안 최대를 보였으며 혈압강하와 동시에 심박수의 증가 현상이 관찰되었다. 그러나 고려홍삼 비사포닌은 혈압강하효과와 심박수의 증가현상은 사포닌에 비하여 미미 하였다. 고려홍삼 사포닌에 의한 혈압강하 현상과 NO와의 상관관계를 규명하기 위하여 혈중 NO를 측정한 결과 홍삼사포닌은 혈중 NO를 상승시켰다. NO합성효소의 활성도를 측정하기 위하여 $[^{3}H]-L-arginine$의 $[^{3}H]-L-cioulline$으로의 변환률을 측정한 결과 고려홍삼 사포닌에 의하여 NO합성효소의 활성도는 증가하였다. 이상의 결과를 종합해 볼 때 고려홍삼은 혈압을 강하시키는 효과가 있으며, 이러한 혈압강하는 주로 사포닌 성분에 의한 것으로 생각된다. 이러한 고려홍삼 혈압강하 현상은 혈중의 NO량을 증가시키는 것에 기인하며 NO의 증가는 NO합성효소의 활성도의 증가에 기인하는것으로 사료된다.

To investigate the effect of ginseng extracts on the changes of flllidity and lysis of liposome reverse phase evaporation vesicle (REV) was employed as model membrane and methylene blue was used as photosensitizer. Fluoresence polarization (P vaule) that represented fluidity of liposome was increased by photooxidation. All of the ginseng saponin inhibited the increasing rate of P value; the order of effect was ginseng water extract>biol saponin>triol saponin>crude saponin. In trapped G-6-P% measurement for lysis of liposome, ginseng water extract and crude saponin promoted the lysis of liposome. Therefore, we thought that ginseng extracts acted as both antioxidant and detergent.

The content and composition of saponin compounds of Panax species were analyzed according to their species, region and processing type of red and white ginseng. The species employed were Korean-, Chinese-, Japanese red ginsengs, and Korean white ginseng of Panax ginseng, American- and Canadian ginsengs of Panax quinquefolium, and Panax notoinseng. Twelve main saponin components in the ginseng were identified and quantified using TLC and HPLC. All three species had remarkably different content and composition. However, within each species they were similar. Twelve major ginsenosides were determined in P. ginseng, eight in p. quinquefolium, and six in P. notoginseng. Of the components of P ginseng Rf, $Rh_1$, $Rh_2$ and Ra were not detected in P quinquefolium, and $Rb_2$, Rc, Rf, $Rh_2$, Ra and Ro not detected in P. notoinseam. Crude saponin content and protopanaxadiol/protopanaxatriol saponin ratio were compared. They were 4.81~5.24% and 1.27~ 1.45 in p. ginsengs, 7.01~7.25% and 2.12~ 2.15 in p. quinquefolium, 9.80% and 0.99 in P. notoineng. The prosapogenin and sapogenin content were different among the Panax species.

The effect of ginseng saponin on aflatoxin(AF) production by Aspergillus parasiticus NRRL2999 and the mutagenicity of produced aflatoxin. The production of aflatoxin were decreased by the addition of ginseng saponin and the most effective concentration was 0.05%. The ratio of aflatoxin $B_{1}$ and aflatoxin $G_{1}$ were not changed by the addition of ginseng saponin. For the nutagenicity test, Ames method were adopted. Mutagenicity of mycelial aflatoxin was decreased by the addition of ginseng saponin on TA98, but not changed on TA100. Mutagenicity of excreted aflatoxin to broth was slightly increased by the saponin on TA98, but decreased on TA100.

Crude saponin and ginsenosides in commercial white ginsengs such as six kinds of whole ginsengs, five kinds of tail roots and one undergrade raw ginseng were analyzed. The contents of crude saponin and ginsenosides in whole ginsengs were found to be 2.7 to 4.6% and 1.0 to 1.7%, respectively. On the other hand, those of tail roots were 3.3 to 7.2% and 1.3 to 4.4%, respectively. The content ratio of PD to PT saponin in whole ginsengs showed a little variation as 0.73 to 0.92, while those of tail roots showed a greater variation in the range of 0.72 to 1.75, indicating that tail roots contain higher content of PD saponin than whole ginsengs did.

The effect of Korean Ginseng saponins (total saponin, PD saponin and PT saponin) on the serotonin type 3 receptor, which is known to be involved in nausea and vomiting following anticancer chemotherapy or the general anesthesia, was investigated. after in vitro transcribed recombinant serotonin type 3 receptor in the Xenopus laevis oocyte, classic two electrodes voltage clamp technique was used. All of ginseng saponins inhibited the response of the agonist, serotonin, on the serotonin type 3 receptor in a dose-dependent manner. PT saponin showed to have the inhibitory effect more than 2 times as potent as PD saponin. Total saponin shifted the serotonin dose response plot to the right (EC$\_$50/, 0.70$\pm$0.17 $\mu$M into 3.57$\pm$1.42 $\mu$M, and Hill coefficient, 2.14$\pm$0.60 into 1.52$\pm$1.00). Ginseng saponin did not change the reversal potential (∼0 mV) of serotonin type 3 receptor. These results suggest that Korean ginseng saponin may have the inhibitory effect on serotonin type 3 receptor.

We have studied the effect of ouabain, tool ginseng saponin, panax saponin C (protopanaxatriol derivative) and ginsenoside $Rb_{1}$ (protopanaxadiol derivative) on $Na^+,K^+$-ATPase and $Mg^{++}$-ATPase activities were determined by the method of Robinson and ATPase activities were determined by the method of King. The $Na^+,K^+$-ATPase activities were inhibitied by 90.1% and 51.1% respectively at the concentration of $10^{-3}M$ and $10^{-4}M$ ouabain. The results are consistent with those of Robinson. The $Na^+,K^+$-ATPase activities were increased by 14.3% and 10.0% respectively at the concentration of $10^{-4}$g/ml and $10^{-5}$g/ml total ginseng saponin. Panax saponin C obtained by the method of Han and ginsenoside $Rb_{1}$ obtained by the method of Shibata were used. The $Na^+,K^+$-ATPase activities were increased in the presence of panax saponin C and the increased activity with panax saponin C was greater than that with total ginseng saponin. On the other hand ginsenoside $Rb_{1}$ showed an inhibitory effect on $Na^+,K^+$-ATPase. Total ginseng saponin, panax saponin C and ginsenoside $Rb_{1}$ had no effect on $Mg^{++}$-ATPase. Therefore, it may be concluded that total ginseng saponin has dual effects on microsomal $Na^+,K^+$-ATPase, that is, panax saponin C exhibits stimulatory action, whereas ginsenoside $Rb_{1}$ shows inhibitory action.

There is a potential role of collagenase-3 in alveolar bone loss and periodontal disease progression, we need to develope or find chemotherapeutic drugs or herbal agents which may regulate the expression of MMP-13. Ginseng saponin, one of the major components of Korea ginseng(panax ginseng) root, has many various biologic effects, such as cytotoxic effect, tumoricidal effects, cytokine regulations, and protein biosynthesis effect. The purpose of this study was to determine the effects of Korea red ginseng saponin on MMP-13 gene expression in osteoblasts. The experimental groups were cultured with ginseng saponin in concentration of 1.0, 10, 25, 50, 100, 250 and $500{\mu}g/ml$ for MTT assay. Primary rat calvarial cells were pre-treated for 1 hour with ginseng saponin(100 ${\mu}g/ml$) and then stimulated with $IL-1{\beta}(1.0ng/ml)$ and PTH(10 nM). MMP-13 gene expression was evaluated by RT-PCR. The results were as follows: Ginseng saponin was cytotoxic to osteoblast at concentration exceeding $250{\mu}g/ml$ for longer than 24 hours in tissue culture(p<0.01). In RT-PCR analysis, steady state MMP-13 mRNA levels were increased approximately 350% by $IL-1{\beta}$, and 400% by PTH when normalized to untreated control. $IL-1{\beta}-indued$ MMP-13 mRNA expression was reduced 50% by pretreatment with ginseng saponin. But ginseng saponin didn't inhibit MMP-13 expression from PTH stimulated cells. This results suggest that ginseng saponin Inhibit $IL-1{\beta}-indued$ MMP-13 mRNA expression.

Total saponin from Korean red ginseng changed thermodynamic parameters of membranes from dipalmitoylphosphatidylcholine (DPPC) and ghost erythrocytes of human. In liposomes from DPPC, temperature of the main transition (Lb'-La) in liquid-crystalline phase increases by 0.2$^{\circ}C$ in average, but enthalpy does not change. Total saponin at a concentration of smaller than $10^5$% "stabilizes" the timid bilayers. At larger than 0.07 of saponin/DPPC ratio, saponin leads to an exclusion of the bound lipid molecules from the main phase transition into lamella liquid crystalline La-phase. Total saponin influences specifically all erythrocyte membrane transitions in a concentration-dependent manner, i.e. on the structures of all the main membrane skeleton proteins. A high structural specificity of saponin with membrane proteins, could be a base of specificity of physiological response of not only erythrocytes, but also other cells.her cells.
