Immunological activities of the combined-administration of Ginseng Radix Rubra and Vitis Fructus were examined in C57BL/6 mice. Ginseng Radix Rubra and Vitis Fructus were extracted with distilled water or 40% ethyl alcohol. Ginseng Radix Rubra water extracts (GW), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:1)], the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus water extracts [GVW(1:3)], 40% ethyl alcohol extracts of Ginseng Radix Rubra (GE), the mixture (1:1) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:1)] and the mixture (1:3) of Ginseng Radix Rubra and Vitis Fructus 40% ethyl alcohol extracts [GVE(1:3)] were administered p.o. once a day for 7 days, respectively. GVW(1:1) and GVW(1:3) decreased the viability of thymocytes increased by GW, but GVE(1:1) and GVE(1:3) increased the viability of thymocytes decreased by GE. GVW(1:1) and GVW(1:3) increased the viability of splenocytes decreased by GW or GE. Also, GVW(1:1) and GVE(1:1) enhanced the population of helper T cell in thymocytes, and GVE(1:1) and GVE(1:3) decreased the population of cytotoxic T cells increased by GE. Furthermore, GVW(1:1), GVW(1:3), GVE(1:1) and GVE(1:3) enhanced the population of $B220^+$ cells decreased by GW or GE, and decreased the population of $Thyl^+$ cells increased by GW or GE, and decreased the population of splenic $CD4^+$ cells increased by GW or GE. In addition, GVW(1:1) and GVW(1:3) decreased the phagocytic activity and the production of nitric oxide in peritoneal macrophages increased by GW, but GVE(1:1) and GVE(1:3) enhanced the phagocytic activity and the production of nitric oxide in peritoneal macrophages decreased by GE. These results suggest that Vitis Fructus has an regulative action on immune response of Ginseng Radix Rubra.

The ginsenosides content of ginseng radices extracts were investigated in the Food Code and the Shibata methods. Crude saponins and each ginsenosides content of the manufactured ginseng radix alba extracts were revealed to be higher than those of the manufactured ginseng radix rubra extracts. A large amount of a ginseng radix rubra specific component(ginsenoside Rg3) was shown in the manufactured ginseng radix rubra extracts. Also a large amoung of ginsenoside Rg3 was shown in the manufactured ginseng radix alba extracts. (omitted)

In order to evaluate estrogenic compounds in natural products, an in vitro detection system was established. For this system, the human breast cancer cell line MCF7 was stably trans-fected using an estrogen responsive chloramphenicol acetyltransferase (CAT) reporter plas-mid yielding MCF7/pDsCAT-ERE119-Ad2MLP cells. To test the estrogenic responsiveness of this in vitro assay system, MCF7/pDsCAT-ERE119-Ad2MLP cells were treated with various concentrations of 17f3-estradiol. Treatments of 10$^{-8}$ to 10$^{-12}$ M 17$\beta$-estradiol revealed significant concentration dependent estrogenic activities compared with ethanol. We used in vitro assay system to detect estrogenic effects in Puerariae radix and Ginseng radix Rubra extracts. Treat-ment of 500 and 50 $\mu\textrm{g}$/ml of Puerariae radix extracts increased the transcriptional activity approximately 4- and 1.5-fold, respectively, compared with the ethanol treatment. Treatment of 500, 50, and 5 $\mu\textrm{g}$/ml of Ginseng radix Rubra extracts increased the transcriptional activity approximately 3.2-,2.7, and 1.4-fold, respectively, compared with the ethanol treatment. These observations suggest that Puerariae radix and Ginseng radix Rubra extracts have effective estrogenic actions and that they could be developed as estrogenic supplements.

This study was performed to investigate the anxiolytic effects of total sponin fraction from Ginseng Radix Rubra (KRG) in mice using the elevated plus-maze model. The water extract of KRG and ginseng total saponins (GTS) purified from the water extract of KRG were administered orally to mice. One hour after administration of KRG water extract and GTS, mice were tested on the elevated plus-maze. The water extract of KRG 100 mg/kg, and GTS 25 and 50 mg/kg did not increase open arm entries and time spent on open arm. However, GTS 100 mg/kg increased the number of open arm entries and time spent on open arm. On the other hand, as the plus-maze test was affected by changes in locomotor activity, an additional test was carried out with the specific aim of monitoring locomotor activity. The water extract of KRG 100 mg/kg, and GTS 25 and 50 mg/kg did not affect the locomotor activity. However, GTS 100 mg/kg significantly decreased locomotor activity. From this study, we suggest that GTS may play an imponant role on the anxiolytic effects in the plus-maze model.

This study was designed to compare the antidiabetic activities between Ginseng Radix Alba (GRA), Ginseng Radix Rubra (GRR) and Panax Quinquefoli Radix (PQR) in multiple low dose (MLD) streptozotocin (STZ) (20 mg/kg i.p injection far 5 days) induced diabetic rats. In the glucose tolerance test, 500 mg/kg of each ginseng ethanol extract was administered intraperitoneally 30 min before glucose challenge. While GRA failed to lower blood glucose level, GRR and PQR both significantly prevented the hyperglycemia when compared with the control group. In the MLD STZ-induced diabetic rats, 300 mg/kg of each ginseng ethanol extract was administered intraperitoneally for 2 weeks. Plasma glucose and insulin levels were markedly improved in all treatment groups. While GRR showed the highest antidiabetic activity, and GRA and PQR revealed somewhat equipotent antidiabetic activities, but less than that in GRR-treated group as far as blood parameters and diabetic symptoms such as polyphagia and polydipsia are concerned. Blood glucose levels were closely associated with plasma insulin levels, and this result may suggest that ginseng ethanol extracts showed the activity to enhance insulin secretion as well as preventing destruction of pancreatic islet cells. To elucidate the relationship between antidiabetic activity and ginsenoside profiles, seven major ginsenosides were quantified by HPLC. We figured out the fact that protopanaxatriol (PPT): proptopanaxadiol (PPD) ratio might play an important role in its hypoglycemia effects.

The effect of water extract composed of panax ginseng radix rubra, acanthopanacis cortex, and cordyceps (PAC) on diabetic animal models were investigated in two different diabetic animal models. FAC water extract significantly reduced the plasma glucose levels on day 30 as compared with the diabetic control group in $KKA^Y$ obese, hyperglycemic and hyperglycemic and hyperinsulinemic mice, and also reduced the plasma glucose levels as well as total cholesterol in multiple low dose (MLD) strep tozotocin-induced diabetic SD rats. PAC water extract also showed an inhibitory effect on reduction of body weight and on development of MLD STZ-induced diabetic state. Elevated kidney hypertrophy, which is a characteristic feature shown in early stage of diabetic nephropathy and calculated as the ratio of kidney mass (g) relative to the body weight (g), was also markedly improved in PAC water extract- treated group as compared to the diabetic control group. Taken together, these data suggest that PAC water extract may have a potential as a antidiabetic agent in type 2 diabetes mellitus.

Uncoupling proteins (UCPs) are transmembrane proton transporters present in the mitochondria. In UCPs. UCP1 and UCP3 play an important role in adaptive thermogenesis by uncoupling mitochondrial oxidation of substrates from ATP synthesis. PPARg coactivator 1(PGC-1) regulates transcriptional activity of PPARg and other nuclear receptors and controls the expression of UCPs. (omitted)

KJHST (Kejihongsarntang) is a modified oriental prescription that consists of five herbs such as Ginseng Radix rubra Koreana, Atractylodis Rhizoma, Zingiberis Rhiaoma, Cinnamomi Ramulus and Glycyrrhizae Radix. For the evaluation of antioxidant and staminal activities of KJHST (Kejihongsarntang), the study was done in comparison of Ginseng Radix rubra (GR). For the antioxidant study, KJHST inhibited hemolysis of erythrocyte and decolored the DPPH(2,2-diphenyl-1-picrylhydrazyl) free radical in a dose depenrlent manner more effectively than GR alone in vitro. KJHST and GR significantly suppressed the time course (1 hr∼6 hr)-level of MDA (malondialdehyde) following AAPH (2,2'-azo-bis-(2-amidino-propane) dihydrochloride) treatment in vivo as compared with control data with no statistical difference. From the evaluation of stamina by swimming test GR and KJHST significantly increased the swimming time in a time and dose dependent manner as compared with control data, while GR was more effective than KJHST in 2 weeks after treatment, though KJHST was more effective than GR at low dose (25 m/kg) 4 weeks after treatment. From the results it can be concluded GR and KJHST had antioxidant and staminal activities.

The purpose of this study is to examine the improvement of endurance exercise performance by taking mixtures of Ginseng Radix rubra and Paeonia Radix. For this purpose, time of exhaustion, $V0_2max$, heart rate, and blood lactate was used as improvement index. The experiments were executed to thirty eight men in their twenties. They were randomly assigned into four groups[CG: control group(n=10), IG: ingestion mixtures group(n=9), TPG: ingestion placebo+training group(n=9), TIG: ingestion mixtures+training group(n=10)]. IG and TIG took mixtures of Ginseng Radix rubra and Paeonia Radix for four weeks, and TPG and TIG exercised once a day, three times a week, exercised for 25 minutes during the first week and added 2 minutes by week during four weeks up to 75% of their maximum heart rate. Time of exhaustion showed statistically significant increase for IG, TPG and TIG. TIG had the longest time of exhaustion and IG the shortest. In case of $VO_2max$, no statistically significant change was found among four groups. However, IG, TPG, TIG showed small increase in $VO_2max$. Similarly, no significant change was found for heart rate in rest even though TIG and TPG appear to have decreasing trend. For maximum heart rate, no significant change was found either, but IG, TPG and TIG showed increase. In case of blood lactate from rest to exercise until 18 minutes, no group had significant decrease. In case of blood lactate in exhaustion, IG, TPG and TIG had significant increase. Blood lactate recovery volume at 5 minutes, 10 minutes, 20 minutes showed no significant results for all four groups, but TIG and TPG had a small increase.
