This study was carried out to determine the effect of white and red Panak ginseng on body weight gain, feed efficiency, epididymal fat weight, and total serum cholesterol and triglyceride levels in male rats (Wister/ST, 8-week-old, 320 g) fed high fat diet. Rats were divided largely into two groups; normal control (NC) and high-fat-diet (HFD)-fed groups. HFD-fed animals were subdivided into 2 groups; HFD-fed control (FC), and HFD- and ginseng-fed groups. HFD and ginseng fed animals were furthor subdivided into white (WG)- and red ginseng (RG)-treated groups. Ginseng-treated groups received ethanol extract at daily doses of 250, 500, 1,000 mg/kg b.w. for 4 weeks. Consequently, a total of 40 rats were divided into 8 groups. Body weight gain of WG-500 (P<0.05), WG1000 (P<0.01) and RG500 (P<0.05) was significantly lower than that of the NC. Feed efficiency showed same result. The epididymal fat weight of WG500, WG1000 and RG250 was markedly lower (P<0.05) than that in FC. Total serum cholesterol level of WG250, WG500, WG1000 and RG1000 groups were significantly lower (P<0.05) than that of FC. Decrease in the total cholesterol level was most significant in WG100 group. Treatment of ginseng significantly reduced serum free cholesterol and triglyceride levels of the HFD-fed rats irrespective of white or red ginseng. Among the test groups, administration of ginseng at daily dose of 1,000 mg/kg b.w. showed the most potent free cholesterol and triglyceride lowering activity. These results led us to the conclusion that administration of ginseng lowers serum total or free cholesterol and triglyceride levels in HFD-fed animals. Moreover the beneficial effect of white ginseng was slightly more potent than that of the red ginseng.

In this study, 8 kinds of fruits and vegetables such as apples, pears and radishes were cut and hot water extracts and Steamed hot water extract from fruits and vegetables were prepared and used as experimental substrates. As a result of fermenting with 1% (W/V) red ginseng extract (W/V) and 8 types of lactic acid bacteria mixed starter added to the lactic acid bacteria fermented extract, the pattern and content of ginsenosides were almost unchanged in the fruit and vegetable extract group and the steam treatment group. However, in the lactic acid bacteria fermented group, the TLC pattern was changed according to the fermentation process and treatment, and the content of ginsenosides converted into Rg₃(S) and Rg₅ increased. No change in the number of lactic acid bacteria (cfu) was observed in all four types of fruit and vegetable extracts. The number of lactic acid bacteria CFU was slightly decreased in the four fermented groups of fruit and vegetable extracts, but the growth inhibitory effect of beneficial bacteria was not significant. The growth inhibitory effect of the three harmful bacteria was not affected by the growth of E. coli and Pseudomonas in the four fruit and vegetable extracts. However, the proliferation of Salmonella was inhibited, which was confirmed as the growth inhibitory effect of the fruit and vegetable extract regardless of whether the steamed hot water extract or red ginseng extract was added.

Experiment was performed to investigate the immunotoxicity of cadmium administered orally and the effect of ginseng petroleum ether fraction on it. Mice were given 3, 30, or 300 ppm cadmium as cadmium chloride orally in the drinking water and injection of ginseng petroleum ether fraction intraperitoneally for 4 weeks. Mice were sensitized and challenged u'ith sheep red blood cells (5-HBC). Immune response was evaluated by delayed type hypersensitivity (DTH), Rosette forming cell (RFC), phagocyte activity, and natural killer cell activity (NK cell activity). In the present study, cadmium suppressed the cellular immunity, It also depressed phagocyte activity very significantly in all cadmium-administered groups, NK cell activity in the cadmium-300 ppm administered group. Ginseng petroleum ether fraction showed restoring effect on the decrease in RFC by cadmium-administration. Remarkably, it showed very significant restoring effect on the depression of phagocyte activity induced by cadmium-administration. From this result, we suppose that the anti-tumor effect of ginseng ether or petroleum ether extract, which has been reported by some other researchers, is mainly due to the increase of phagocyte activity by it's administration.

The effects of korean red ginseng (KRG) extracts on orifacial pain control in terms of the systemic inflammatory response and pharmacological effects as health supplements were investigated. The experimental group were divided into three groups, the control group (n=6), formalin (5%, $50{\mu}{\ell}$) injection group (n=6), and formalin (5%, $50{\mu}{\ell}$) injection added KRG administrated group (4.5 ml/kg, n=6). The KRG administrated group prior to the formalin injection significantly attenuated the behavioral response compared to that of the control group. Pain reduction was suppressed mainly from 15 min to 30 min. The KRG administrated rats showed significantly reduced p38 MAPK, iNOS and Nrf2 expression in the brain and medulla oblongata according to Western blot analysis. These findings suggest that KRE may have a useful effect on orificial pain control functions by preventing the p38 MAPK pathway.

The present study was conducted to investigate the effects of Korean red ginseng water extract (KRGWE) on developmental toxicity caused by the environmental estrogen bisphenol A (BPA) in Sprague-Dawley rats. fifty males successfully mated were randomly assigned to five experimental groups, 1.e., group I (vehicle control), group II (BPA 1000mg/kg), group III (KRGWE 400mg/kg), group IV (BPA 1000mg/kg & KRGWE 200mg/kg), and group V (BPA 1000mg/kg & KRGWE 400mg/kg). The test articles were administered by gavage to mated females from gestational days (GD) 1 through 20 (sperm vaginal lavage=day O). All females were subjected to caesarean section on GD 21 and their fetuses were examined for external, visceral, and skeletal abnormalities. In the group II, significant maternal toxic effects including suppressed body weight, decreased body weight gain during pregnancy, and reduced food consumption were observed in pregnant rats. The minimal developmental toxicity including fetal ossification delay was also found in fetuses. In addition, a tendency for increased pregnancy failure, increased pre-and postimplantation loss, and decreased fetal body weight was observed. However, no fetal morpho-logical abnormalities were seen in surviving fetuses at a dose level of 1000mg BPA/kg. On the other hand, the maternal toxicity and developmental toxicity found in the groups IV and V were comparable to those of the group II. There were no adverse signs of either maternal toxicity or developmental toxicity in the group III. These results showed that administration of BPA at a dose level of 1000mg/kg to pregnant rats resulted in significant maternal toxicity and minimal developmental toxicity, and that no protective effects on BPA-induced maternal toxicity and developmental toxicity were found by concomitant gavage dosing of KRGWE.

The purpose of this study is to confirm the radiation protection and recovery effects of natural mixed radiation protection agents. Red Ginseng, Saururus chinensis (Lour.) Baill. and Rubus coreanus Miq. mixed extract was orally administered to male SD rats and changes were observed in the blood, small intestine and prostate. The experimental group was organized into a general control group (NC Group), mixed extract administration group (RSR Group), 6 Gy irradiation group (IR Group), and irradiation group after administration of the mixed extract (RSR+IR Group). Among them, the RSR Group and RSR+IR Group were orally administered 2 cc (36.6 mg/day/250 g) of the extract once for two weeks at the same time, and at the end of administration, the IR Group and RSR+IR Group were irradiated with 6 Gy whole body radiation. Looking at hematological changes, the RSR + IR Group showed higher recovery and higher levels of white blood cells and platelets than the IR Group. And SOD levels showed high activity in the group administered the extract. Looking at the small intestine, compared to the IR Group, the RSR+IR Group shows better protection and recovery of small intestine villi length. Likewise, in the prostate, there is less cell damage in the RSR+IR Group, and on the 21st day, the prostate spacing is constant, showing a similar pattern to the NC Group. It is believed that the mixed extract used in the study has radiation protection and recovery effects in male SD rats and will be helpful in the study of mixed radiation protection agents.

The swelling and hydration properties of Korean red ginseng tails and yield of total solids in extract were studied during extraction with ethanol solution having a concentration of 0-90% at $60-100^{\circ}C$. Extraction was carried out 5 times which was taken 8 hours per each time of extraction. The swelling, hydration and total solids yield were increased as the ethanol concentration decreased and as the extraction temperature raised. The cumulative value of solids yield suggested that three times of extractions with water or 70% ethanol were effective to recover more than 84%. Linear regression analysis on the properties investigated and extraction conditions showed a linear logarithmic relationship .

This study was investigating the anti-obesity effects of diets with a mixture of cheese, red ginseng and fermented mature fruit of Rubus coreanus Miquel. We fed the experimental diets (SC5, SC10) supplemented with 5% or 10% cheese containing of fermented mixture, then orally administered the extract of fermented mixture (RB100, RB300) at a concentration of 100 or 300 mg/kg body weight to SD rats with high fat diet (HFD). The results were as follows: Sample cheese groups decreased visceral fat mass and adipocyte size of stomach compared to that of HFD group. Additionally, lipid droplets of liver in sample cheese groups were smaller than that in HFD group. The serum triglyceride (TG), total cholesterol (tChol), glucose, leptin, and insulin levels in sample cheese group were lower than that in HFD group. But, the serum adiponectin and HDL-cholesterol (cHDL) levels were higher than that in HFD group. These results suggest that fermentation of red ginseng and Rubus coreanus mixed with cheese might be helpful in preventing obesity in high fat diet-fed rats.

We produced the Red ginseng residue water(RGW), ethanol(RGE), 1,3-butylene glycol(RGB) extract from Red ginseng residues, analyzed the components of the extracts by HPLC, and evaluated the cell viability on B16F10, antioxidant and anti-wrinkle effects for application of cosmetics. As a result, RGW, RGE, RGB have various ginsenoside and its content of RGB were higher than RGW, RGE as component analysis by using high performance liquid chromatography(HPLC). RGW showed similar with RGB in cell viability on B16F10 which were higher than RGE. DPPH radical scavenging activity increased according to the RGE>RGB>RGW. SOD-like activity increased according to the RGB>RGE>RGW. Also, elastase inhibition effect increased according to the RGW>RGB>RGE. These results suggested that RGB and RGW may have potential for the application of antioxidant and anti-wrinkle effects for cosmetics.

Ginseng is one of the most widely used medicinal plants, particularly in East Asian countries. Certain fractions or purified ingredients of ginseng have been shown to exert inhibitory effects on growth of cancer cells in culture or on tumorigenesis in experimental animals. Moreover, a recent epidemiologic study reveals that ginseng intake is associated with a reduced risk for environmentally related cancers such as esophageal, gastric, colorectal, and pulmonary tumors. Heat treatment of Panax ginseng C. A. Meyer at the temperature higher than that applied to the conventional preparation of red ginseng yielded a mixture of saponins with potent antioxidative properties. Thus, the methanol extract of heat-processed ginseng (designated as'NGMe') attenuated lipid peroxidation in rat brain homogenates induced by ferric ion or ferric ion plus ascorbic acid. Furthermore, the extract protected against strand scission in f Xl 74 supercoiled DNA Induced by UV photolysis of H2O2 and was also capable of scavenging superoxide generated in vitro by xanthine/xanthine oxidate or in differentiated human promyelocytic leukemia (HL-60) cells by the tumor promoter,12-0-tetvade- canoylphorbol-13-acetate (TPA). Since tumor promotion is closely linked to oxidative stress, we have determined possible anti-tumor promotional effects of NGMe on two-stage mouse skin tumorigenesis. Topical application of NGMe onto shaven backs of female ICR mice 10 min prior to TPA significantly ameliorated skin papillomagenesi s initiated by 7,12-dimethylbenz (a) anthracene (DMBA).'Likewise, TPA-induced epidermal ornithine decarboxylase activity and elevation of tumor necrosis factor-a were suppressed signifies%fly by NGMe pretreatment. NGMe topically applied onto surface of hamster buccal pouch 10 min before each topical application of DMBA inhibited oral carcinogenesis by 76olo in terms of multiplicity. Taken together, these results suggest that processed Panax ginseng C. A. Meyer has potential cancer chemopreventive activities.
