This study was made to observe changes in hemograms of the Sarcoma-180 mouse treated with extracts of Poria cocos and Panax ginseng. The life span of the Sarcoma-180 mouse administered with the mixture of the extract of Panax ginseng with the extract of P. cocos and the extract of P. cocos was extended more than the non-treated group. In the body weight of the Sarcoma-180 mouse, the non-treated group was increased more than the normal group and the groups administered with the mixture of ginseng extract with hoelen extract and hoelen extract. In the numbers of white blood cell especially lymphocyte, the groups administered with the mixture of ginseng extract with hoelen extract and hoelen extract were similar to the normal group, but the non-treated group was decreased. The Hematocrit, mean corpuscular volume and mean corpuscular hemoglobin in the mice infected with Sarcoma-180 were not significantly different between the group treated with extracts of them and the non-treated group. In the distributions and sizes of white blood cell and platelet in the mice, the group administered with the Hoelen extract was similar to the normal group comparing to the non-treated group.

The effects of white ginseng and red ginseng ethanol extracts on the proliferation, nitric oxide (NO) production and tumor necrosis factor-$\alpha$ (TNF-$\alpha$) in human Band T lymphocytes isolated from blood cell of sasang constitution were examined in vitro. White ginseng extract known as medicine suitable for soeumin constitution showed the highest immune activities such as proliferation, NO production and TNF-$\alpha$ in soeumin constitution, and followed by taeeumin and soyangin, respectively (P<0.05). However, there were immunologically insignificant differences among sasang constitution lymphocytes treated by red ginseng ethanol extract. Both white and red ginseng ethanol extracts showed significantly higher immunological activities than LPS-induced sasang constitution lymphocytes on NO production and TNF-$\alpha$ release (P<0.05). The different immunological activities of white and red ginseng extracts in sasang constitution lymphocytes might be due to the component changes during the processing of ginseng. Thus, the findings of components suitable for all constitutions from red ginseng extract could be applied as a new constitution marker.

Ginseng extracts were frnctionelod into several fractions with carious organic solvents, and the effects of these fractions on the activity of aminoacyl-tRHA synthetase was examined. Fractions which showed positive effect on the activity of the aminoacyl-tRNA synthetase were obtained both from white ginseng and red ginseng. The total methanol extract of whit ginseng and the ether extract from the total methanol extract of red ginseng gave Positive results. Therefore it may be Presumed that the Positive components have rather nonpolar nature.

Radiation protective fraction was Isolated and partially purified from Korean white ginseng. The effect of the fraction was studied on the cell survival of W-damaged CHO-Kl cells. As a result, it was found that the fraction increased the survival rate of damaged cells significantly within the dose range of which cytotoxicity did not appear This fraction was separated into two parts by adding butanol, namely the precipitated protein component and the butanol extract. Damaged cells were treated with each of these components and their survival rates were measured. The protein component demonstrated significant increase in the survival rates, while the butanol extract showed no such increment. These results suggest that the radiation protective effect of the ginseng fraction is originated from the butanol-precipitated protein component, not from the butanol-soluble compounds.

This study was to examine antioxidative effects of ginseng extracts on liver of high fat diet-treated mice. ICR male mice were given high fat diet with red ginseng or white ginseng extracts (500, 1500, 3000 mg/kg/day, orally) for 4 weeks. We also Investigated the relationship between lipid peroxidation and ginseng extracts on the oxidative stress. We measured the levels of malondialdehyde (MDA, a marker of lipid peroxidation), hydrogen peroxide, superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH) in liver tissue. The activities of SOD was generally low in all ginseng extract groups. But the activity of GPx was high in all ginseng extract groups. The hydrogen peroxide contents were similar in almost all groups. The level of GSH was higher in all ginseng extract group in high fat diet (FD) group. The levels of MDA (the end product of lipid peroxidation) were lower in all ginseng extract groups than in FD group. These results that the antioxidant effects of red ginseng and white ginseng extracts prevent oxidative damage by antioxidant effects involving SOD, GPx and increasing the ability of the body to synthesize endogenous antioxidants. It was concluded that ginseng can protect against oxidative stress by high fat diet through its antioxidant properties.

It was found that petroleum ether extract of White Ginseng had a very slightly stimulating effect on the RNA biosynthesis of Baker's yeast, while both ethanol extract of White Ginseng(WGpet-alc) and Red Ginseng Extract(RGE) showed a significant stimulating effect on the RNA biosynthesis and its activity to change mononucleotide composition of the yeast RNA was noticeable; RGE induced a remarkable decrease of AMP, CMP and especially of UMP, however a marked increase of GMP, and it was observed that the molar ratio of GMP was 78.5 % of all mononucleotides of the yeast RNA. It is of interest that these results are closely related with the stimulating effect of protein biosynthesis of Baker's yeast cells.

Curd yoghurts were made with ginseng products, ginseng extract, white ginseng powder and tail ginseng powder, which have pharmacological effects and are palatable by Korean. The acidity, number of lactic acid bacteria, and viscosity of yoghurts were examined and taste, flavor and preservation of yoghurts were also tested. The results obtained were summarized as follows. 1. The acidity of yoghurts was higher for ginseng yoghurts, especially for tail ginseng yoghurt(1.13%) than for control Yoghurt(0.95%). 2. The number of lactic acid bacteria was higher for ginseng yoghurts, especially for tail ginseng yoghurt($9.8{\times}10^8/ml$) than for control yoghurt($6.5{\times}10^8/ml$). 3. The viscosity of yoghurt was higher for ginseng yoghurt, especially for white ginseng powder yoghurt than for control Yoghurt. 4. The score of taste and flavor of yoghurt were higher for ginseng yoghurt, whereas those of texture of yoghurt were lower than control yoghurt. However, the score of total sensory test was higher for tail ginseng yogurt than other yoghurts. 5. When yoghurts were stored at $5^{\circ}C$ for 10 days, the pH, acidity and number of lactic acid bacteria in yoghurts were not changed significantly.

Succinate dehydrogenase was activated by ethyl acetate extract from the methanol extract of white ginseng previously treated with petroleum ether and ethyl ether to remove all highly nonpolar components, and the residual aqueous solution from the ethyl acetate extraction. Also, all of the extracted fractions of red ginseng except the ether extract gave positive results. On the contrary to some suggestions by other workers that alkaloids of ginseng may enhance the succinate degydrogenase activity, our results show that the alkaloids may have exhibited some inhibitory eject on this enzyme.

The authors have already shown that 6 year old red ginseng extract or its powder has remarkable anticarcinogenic effects. In this study, we further investigated whether fresh ginseng or white ginseng has similar anticarcinogenic effects and also if their anticarcinogenic effects are related to the types and ages of ginseng using Yun's anticarcinogenicity test (9 week medium term bioassay model). Dried fresh ginseng and red ginseng at 1.5, 3, 4, 5 and 6 years, and while ginseng at 3, 4, 5 and 6 years were used. The following results were obtained: 1) In the dried fresh ginseng treated groups, the incidence of lung adenoma induced by benzo(a)pyrene was 41.39) and its incidence was reduced to 31.2%, 30.0%, 31.3%, 30.7% and 27.8% after co-treatment with 1.5, 3, 4, 5 and 6 year-dried fresh ginseng, respectively. A significant effect was observed only in 6 Year-dried fresh ginseng. 2) In the white ginseng treated groups, the incidence of lung adenoma induced by benzo(a)pyrene was 45.0% and its incidence decreased to 41.3%, 38.0%, 31.6%, and 25.3% after co-treatment with 3, 4, 5 and 6 year-white ginseng, respectively. Five and 6 year-ginsengs showed significant inhibition of lung adenoma. 3) In the red ginseng treated groups, the incidence of lung adenoma induced by benzo(a) pyrene was 48.6% and its incidence diminished to 37.9%, 41.7%, 31.7%, 28.3% and 25.5% after co-treat-melt with 1.5, 3, 4, 5 and 6 year-red ginseng, respectively. In 4, 5 and 6 year-ginsengs, the anticarcinogenic effect was prominent. From the above results, we concluded that a significant anticarcinogenic effect was observed in 6 year-dried fresh ginseng, 5 and 6 year-white ginsengs, and 4, 5 and 6 year-red ginsengs.
