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.

When ginseng saponin fractions were treated with secretion regulatory agents, it increased cAMP level at the case of thyrotropin (but the amounts were small). Total saponin increased cAMP level at DEcAMP and isoproterenol, and decreased the level at carbachol and propranolol, but at NaF it had little effect. When diol saponin or triol saponin were treated with secretion regulatory agents, biol saponin decreased cAMP level but triol saponin increased it except for isoproterenol. Also, in propra%olol, which inhibits the increase of CAMP level, diol and triol saponin showed crossing effect, too. From the above results, ginseng saponin fractions are believed that it has the, effects of promotion or inhibition on cAMP production in the thyroid , both diol saponin and triol saponin have crossing effect on thyroid hormone secretion regulatory agents. The normalizatin action of ginseng saponin fractions is notable at the case of NaF and carbachol.

To investigate the effect of ginseng saponin fractions (total saponin, diol saponin and triol saponin) on the antibody production and on the recovery of immunosuppression in mouse, chick ${\gamma}$-globulin was used as immunogen and CY(cyclophosphamide) as immunosuppressive drug. The effect of ginseng saponin fractions on the production of total serum protein was investigated also. Circulating antibody was measured with ELISA method. Total saponin, dial saponin and triol saponin resulted 4 times higher titer values compared to control group in the production of antibody but resulted no effect on the recovery of immunosuppression induced by CY. From the above results ginseng saponin fractions are believed to effect on intact immune system and to promote antibody production by helping the cooperations among lymphocytes or the growth of lymphocytes. And the increase of total serum protein has no direct relations with the increase of circulatory antibody.

The effects of ginseng saponin on the activity, phosphorylation, [$^{3}$H] ouabain binding and light scattering (disruption) of purified $Na^{+}$ ,$K^{+}$ -ATPase isolated from the outer medulla of sheep kidney were compared to those of gypsophila saponin, sodium dodecylsulfate (SDS), and Triton X-100 on the same parameters. $Na^{+}$ , $K^{+}$ -ATPase activity, phosphorylation, and [$^{3}H$] ouabain binding were inhibited by ginseng saponin (triol>total>diol), SDS, or Triton X-100, but increased by gypsophila saponin. Low doses of ginseng saponin (3.mu.g saponin/.mu.g protein) decreased phosphorylation sites and ouabain binding site concentration (Bmax) without any change of turnover number and affinity for ouabain binding which were decreased by high dose of ginseng saponin (over 10.mu.g saponin/.mu.g protein), SDS or Triton X-100. On the other hand, gypsophila saponin increased the affinity without any change of Bmax for ouabain binding. Inhibition of $Na^{+}$ ,$K^{+}$ -ATPase activity by ginseng saponin and SDS or Triton X-100 appeared before and after decrease in light scattering, respectively. These data suggest that ginseng saponins (total, diol, triol saponin) inhibit $Na^{+}$ , $K^{+}$ -ATPase activity by specific direct and general detergent action at low and high concentrations, respectively, and this inhibitory action of ginseng sapornin to $Na^{+}$ , $K^{+}$ -ATPase is not general action of all saponins.

To study the effects of ginseng saponin components on the signal transduction in the ac tivation of murine macrophages, phagocytosis and Intracellular calcium concentration of peritoneal exuded mouse macrophages were examined. The phagocytosis was increased significantly after treatment with total saponin, diol-saponin, $Rg_1$ and $Rg_2$, but triol-saponin was unable to increase phagocytosis. The phagocytosis were increased when H7, a PKC inhibitor, was pretreated and increased significantly by saponin fractions except total saponin. Pertussis toxin, which inactivates G-protein, decreased the phagocytosis. But the phagocytosis was restored to the control level by saponin fractions and the phagocytosis was increased significantly by $Rg_2$ and $Rg_2$. The triol saponin increased phagocytosis approximately by 2-fold as compared with the TMB-8 treated group. Peritoneal exuded macrophages displayed a prominent rise in cytosolic calcium following treatment with triol-saponin, $Rg_1$, $Rg_2$ and $Rg_2$. Incubation of macrophages with PT resulted in an inhibition of cytosolic calcium mobilization, but increased cytosolic calcium mobilization with saponin fraction.

It has been known that the ginseng extracts activate the lipid metabolism in animal body. The experiments were undertaken to elucidate the effects of total, diol, and trial saponin of ginseng on the activities of acyl Co-A synthetase and hydroxyacyl Co-A dehydrogenase involved in fatty acid metabolism in normal albino rat liver. The acyl Co-A synthetase activity, in vitro, was increased by 20% with treatment of 2.5${\times}$10-3% total saponin, by 14% with 2.5${\times}$10-3% diol saponin, arid 30% with 2.5${\times}$10-4% triol saponin, respectively. And the enzyme activity was increased by 27% at 2 hours after intraperitoneal injection of total saponin. Hydroxyacyl Co-A dehydrogenase activity, in vitro, was increased by 77% with 10-4% total saponin, by 64% with 10-2% diol saponin, and by 72% with 10-3% triol saponin, respectively. Also, the enzyme activity, in vivo, was increased by 15.3% and 33% at 2 hours and 4 hours.

Alternative or complementary medicine plays an important role in health care system. Ginseng, being one of the most popular oriental herbs, is believed to contain various steroid hormone activity. Ginseng has been demonstrated pharmacological effect in the cardiovascular, endocrine, central nervous, and immune system. Our objective was to study that total saponin might mediate some of their actions by binding to the steroid hormone receptor, as they share many of the actions of steroid hormone in various physiological system. Using total saponin from Panax Ginseng, we have studied the possibility of total saponin being a potential estrogen receptor, androgen receptor, and retinoic acid receptor ligand. Total saponin activated the transcription of both the estrogen and androgen responsive luciferase reporter plasmids at a concentration of 100$\mu\textrm{g}$/ml in COS cells transiently transfected with the corresponding receptor and hormone responsive receptor plasmids. And total saponin caused a concentration-dependent stimulation of estrogen receptor. Total saponin increased the expression of estrogen responsive c-fos proto-oncogene at the protein level in MCF7 cells at 24 h treatment as examined by Western analysis. The c-fos induction was used as a specific marker of estrogen responsiveness. This activation was inhibited by the specific estrogen receptor antagonist, ICI 182,780. However, total saponin failed to activate the retinoic acid receptor in COS cells transiently transfected with the corresponding receptor and retinoic acid responsive reporter plasmids. These results show that total saponin is capable of activating estrogen and androgen receptors.

This study was carried out to obtain the basic information for non-saponin contents that can be used to index fresh ginseng roots (Panax ginseng C. A. Meyer) cultivated in the Republic of Korea and China. Non-saponin components in fresh gingeng roots which were cultivated in various areas and ages in Korea were determined. Acidic polysaccharide, total polysaccharide, crude polyacetylene were quantitatively analyzed by using the method of spectrophotometric determination, while the total protein was analyzed by using Lowry method. The results show that there were no statistically significant differences for the average contents of four non-saponins among 4-years-old, 5-years-old, and 6-years-old fresh ginseng roots. Additionally, this study assessed the average contents of non-saponin components in 4-years-old fresh ginseng roots (Panax ginseng C. A. Meyer) which were cultivated in Korea and China. The result showed that the average contents of crude polyacetylene and acidic polysaccharide were statistically significant. Four-years-old fresh ginseng roots cultivated in Korea had the higher average contents of crude polyacetylene and acidic polysaccharide than those cultivated in China. However the average contents of total polysaccharide and total protein had no statistically significant difference.

This study was carried out to isolate saponin compounds from red-ginseng efflux, which was produced during the industrial processing of red-ginseng from fresh ginseng. We isolated crude saponin from the efflux extract (moisture content 35.0%) by using Diaion HP-20 adsorption method. Non-saponin fraction, which was adsorbed on Diaion HP-20 resin, was removed by eluating with $H_{2}O$ and 25% spirit. Then crude saponin was eluated with 95% spirit, continuously. Saponin in the eluated fractions was confirmed by TLC analysis. Crude saponin isolated from red ginseng efflux extract contained 12.10% of saponin. whereas those of white ginseng and red-ginseng were 3.30 and 3.39%, respectively. Ginsenoside contents showed the highest contents kin crude saponin from red ginseng efflux extract. Expacilly, the ginsenoside-$Rb_{1}$ and Re showed the highest contents in red-ginseng efflux extract when compared with those of white ginseng and red ginseng crude saponins. And the other ginsenosides except ginsenoside-$Rb_{1}$ and -Re also showed the highest contents in red ginseng efflux extract. However, the ratio of PD saponin (Panaxadiol saponin: $Rb_{1}+Rb_{2}$+Rc+Rd) to PT saponin (panaxatriol: $Re+Rg_{1}$) showed almost the same level when compared with those of ginseng saponin fractions. Ratio of PD/PT from red ginseng efflux extract was 1.99. Ratios of PD/PT from white ginseng and red ginseng were 1.85 and 1.84, respectively. Saponin purity, which was calculated by ratio percent of total ginsenoside to curde saponin content, was 45.90%. In case of white ginseng and red ginseng, the purities were 35.50 and 36.00%, respectively. However, by PHLC analysis, we confirmed that crude saponin isolated from red ginsengs. It suggested that crude saponin isolated from red ginseng ellux also would be useful component as ginseng saponins.
