This study was performed to examine the anti-cancer effect of Red Ginseng in the DENGalN-PH-induced hepatic tumor model system in rats. One hundred of male SPF Sprague-Dawley rats(6weeks old) were randomly divided into five groups. Rats in groups 1, 2, 3, and 4 were administered to diethylnitrosamine intraperitoneally 200 mg/kg body weight for the caner initiation. Rats in group 5 were given to saline as a control. On two weeks after cancer initiation, rats in groups 1 and 3 were fed on diet containing 0.01% of acethylaminofiuorene(AAF) which is strong cancer-promotor for 6 weeks, while rats in groups 2 and 4 were fed on water containing 0.05% of phenobarbital which is weak cancer.promotor for 6 weeks. Rats in groups 1 and 2 were treated with diet containing 3% of Red Ginseng for six weeks(from 9th week till 15th week after cancer initiation). Rats in all groups were necropsied time-sequencially at 8, 15, and 36 weeks. The hepatic lesions of rat treated with carcinogens expressed glutathione S-transferase placental form(GST-P) at 8 week. The GST-P positive foci of rats treated with AAF were larger than that of any other rats, while the GST-P positive foci of rats treated with AAF and red ginseng were significantly decreased. This anti-cancer effect of Red ginseng might be involved in the enhacement of natural killer cell activity. To know whether there is direct relationship between Red Ginseng and natural killer cell activity, the activity of natural killer cell was examined after treatment AAF, AAF+Red ginseng and Red ginseng only, respectively. Comparing with natural killer cell activity in AAF-treated group, natural killer cell activity was significantly activated in AAF+ Red ginseng-treated group. This indicated that Red ginseng might enhance natural killer activity after treatment carcinogen in rats. These results suggested that Red ginseng might have a cancer prevention ability by promoting natural killer cell activity during hepatocarclnogenesis.

Non-saponin gingseng fraction components (NSRG) have been known to have a variety of biological activity. However, the effects of these components on the function of brain cell have not been characterized in detail. In this study, we investigated the preventive effect of non-saponin red ginseng components on acrylamide (ACR)-induced suppression of neural cell adhesion molecule (NCAM), which is highly expressed in neuronal cells. The data showed that NSRG blocked the suppression of NCAM expression by ACR in neuroblastoma cells (SK-N-SH). In addition, NSRG significantly increased NCAM expression in ACR-nontreated neuroblastoma cells. NSRG treatment resulted in the increase of cell proliferation in a concentration-dependent manner. We also examined whether NSRG could modulate the NO production of astrocytes. When glioma cells (C6) were treated with various concentrations of NSRG (100-300 ug/ml) in the presence or absence of $IFN-{\gamma}$ for 24 hours, NO production was suppressed in $IFN-{\gamma}-$stimulated C6 cells. Taken together, these results demonstrate that treatment of brain cells with NSRG results in the enhancement of proliferation, the suppression of NO production and the protective effect on NCAM expression impaired by ACR. Thus, the present data suggest that NSRG has proliferative and neuroprotective effects and these effects could be useful in neuronal diseases.

The clinical efficacies of Korean Red Ginseng for improving sexual function has been reported only by self-reporting questionnaires.AVS-Penogram is a method evaluating natural penile blood flow changes by Gamma-camera after intravenous injection of Techmetium 99$\^$m/-RBC and also stimulating by erotic video tape. To more objectively evaluate the efficacies of Korean Red Ginseng for erectile function, we applied AVS-Penogram as a objective diagnostic tool. AVS-Penogram studies were done in 28 patients with erectile dysfunction after administration of Red Ginseng(19) or placebo(9) group. The pattern of AVS-Penogram before medication were normal type in 4, impossible in 2, unstable in 20, delayed in 1, and mixed in 1. The unstable type were the most prevalent observed in 71.4% of all patients. The patterns of AVS-penogram were 2.2. 13.1 in Red Ginseng group, while in placebo group normal 2, unstable 7. After 4 weeks in Red Ginseng group, there were 3 cases of improved penogram findings, while only 1 in placebo group. There were no statistical significancies in the type of penogram changes on both group. But the maximum radioactivity were improved in 11 patients(57.9%) in Red Ginseng group, while 2(22.2%) in placebo group. There were statistical significancies in comparing the maximal radioactivity of penogram on both group. These AVS-Penogram findings shows, encouraging results of by increased penile blood flow Korean Red Ginseng our medication. Further study is more needed to reconfirm these results by more concentrated active formulations of sapanonin St other active ginsenosides. These promising results will lead to develop a new remedy for erectile dysfunction by Korean Red Ginseng

For centuries, ginseng has been used for the therapeutic purpose in oriental herb medicine. Several studies have been conducted in the past to evaluate the effect of ginseng on erythropoiesis. However the results were controversial. We therefore attempted in the present studies to evaluate the effect of ginseng on the erythropoietic activity. In one series of experiments, the recovery pattern of peripheral blood(red cell count, hemoglobin content, hematocrit and reticulocyte count) was studied in posthemorrhagic anemic rabbits. After animals were maintained with normal(control group) or 1 gm% ginseng (experimental group) diet for 2 weeks, hemorrhagic anemia was induced by withdrawing blood equivalent to 25% of the total blood volume and then changes in peripheral blood were followed for following 30 days. In other series of experiments, we studied effect of ginseng on erythrokinetics using $^{59}Fe$. $^{59}Fe(10{\sim}40\;{\mu}Ci/animal)$ was injected intravenously after animals were fed with normal (control group) or 1 gm% ginseng(experimental group) diet for 2 weeks. And radioactivities in the blood compartments were measured at appropriate intervals for 15 days. Front these various erythrokinetic parameters were estimated. Results are summarized as follows: 1) Reticulocyte count was higher in the experimental group than in the control group after 2 weeks of administration of experimental diet. During the posthemorrhagic period, the reticulocyte count increased in both the control and experimental groups, but the increase appeared much earlier in the experimental group. 2) The posthemorrhagic recoveries of hematocrit, hemoglobin content and red cell count appeared to be faster in the experimental group as compaired with the control group. 3) The half life$(T_{1/2})$ of $^{59}Fe$ in the plasma was significantly(P<0.05) shorter in the experimental group(82.6 min, N=8) than in the control group(121 min, N=6). Plasma iron turnover (PIT) of the experimental group (1.78 mg/dl/24 hr.) was approximately 4 times greater than that of the control group(0.45 mg/dl/24 hr.). 4) The maximum red cell utilization(RC-U) was 82.1% in the experimental group ana 74.5% in the control group. Red cell iron turnover(RIT) of the experimental group(1.62 mg/dl/24 hr.) was slightly higher than that of the control group(0.35 mg/dl/24 hr). 5) Erythron turnover was significantly(p<0.05) greater in the experimental group(1.27 mg/dl/24 hr.) than in the control group(0.24 mg/dl/24 hr.). Marrow transit time of the experimental group(2.05 days) tended to he faster than that of the control group(2.84 days). These results suggest that the gingseng improves the recovery of posthemorrhagic anemia and stimulates the erythropoiesis in rabbits.

In this study, we identified that the fermentation of Korean indigenous probiotics and red ginseng produced ginsenoside compound K (CK) from major ginsenosides. Based on whole genome sequencing of 19 probiotics species, β-glucosidase, α-arabinofuranosidase, β-xylosidase, and α-rhamnosidase related to bioconversion of ginsenosides are identified in the genome of 19 species, 3 species, 6 species, and 8 species, respectively. Among the 19 probiotics species, Bifidobacterium longum CBT BG7 converted from ginsenoside Rb1 to CK, and both B. breve CBT BR3 and B. lactis CBT BL3 converted ginsenoside Rb1 to Rd. The final concentration and yield of ginsenoside F2 and CK were higher in the fermentation with the nondisrupted cells than with disrupted cells. The combination of both CBT BG7 and BL3, and CBT BG7 and BR3 showed higher amounts of F2 than CBT BG7 only. CBT BG7 with adding α-amylase increased the amounts of F2. In this study, we identified that the fermentation of both Korean indigenous probiotic bacteria CBT BG7, BR3 and BL3, and red gingseng is able to produce CK, a bioactive compound that promotes health benefits.

Ginseng root, as a folk medicine, has been used in far eastern countries for thousands of years. Ginseng extract has been shown to have a variety of effects on the activity of the central nervous system, promoting stimulation as well as inhibition of the cortical activity. A survey of the relevant literatures has indicated that the putative anxiolytic activity of red ginseng has not been scientifically investigated. Therefore, the present study was designed to assess anxiolytic effect of gingseng total saponins(GTS). The putative anxiolytic effects of several fractions of GTS were investigated in mice using an elevated plus maze paradigm. Single dose administration of TS Fr.-I showed anxiolytic action in mice. Anxiolytic effect induced by TS Fr.-I was similar to that induced by diazepam. TS Fr.-II, TS Fr.-III and TS Fr.-IV did not show the anxiolytic action compared with that of TS Fr.-I. It was suggested that regulation of GABAergic neurotransmission may be important in the action of GTS. The Interaction of GTS fractions with benzodiazepine receptor was performed using rat cortical membranes. GTS inhibited the binding of [3H] Ro 15-1788 on the benzodiazepine receptor. Among from TS fractions, the binding activity of GTS in the TS Fr.-IV was highest, which did not show the anxiolytic activity. From these results, we conclude that GTS has anxiolytic action, and this is not related to benzodiazepine receptor binding activity.
