The effects of extract mixture of red ginseng and steamed Rehmaniae radix prepared for antidiabetic activity was examined in streptozotocin-Induced diabetic rats. The increased blood glucosec level in the streptozotocin-induced diabetic rats was significantly decreased by the treatment with the mixture (800, 1600 mg/kg, p.o.). However, neither red ginseng extract nor steamed Rehmaniae radix extract alone showed significant hypoglycemic effects. The mixture prevented a weight loss in streptozotocin-induced diabetic rats. These results suggest that the mixture has the relieving action against streptozotocin-induced hyperglycemia.

Objectives : Nitric oxide(NO) is a reactive free radical and a messenger molecule in many physiological functions. However, excessive release NO of induces neurotoxicity. We investigated whether a mixture of red ginseng and paeonia radix prossesses a protective effect against sodium nitroprusside(SNP)-induced apoptosis in the human neuroblastoma cell line SK-N-MC. Methods : We performed 3- (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay, 4,6-diamidino-2-phenylindole(DAPD) staining, terminal deoxynucleotidyl transferase(TdT)-mediated dUTP nick end labeling(TUNEL)assay, DNA fragmentation assay, reverse transcription-polymerase chain reaction(RT-PCR), Western blot analysis, and caspase-3 enzyme activity assay in SK-N-HFC cells. Result : MTT assay showed that SNP treatment significantly reduced the viabilities of cells and that pre-treatment with the red ginseng and paeonia radix mixture alleviated SNP-induced cytotoxicity. The cells treated with SNP exhibited several apoptotic features, while those pre-treated fir 1 h with the mixture of red ginseng and paeonia radix 1 h prior to SNP expose showed reduced apoptotic features. In addition, the cells pre-treated with the red ginseng and paeonia radix mixture for 1 h prior to SNP expose increased bel-2 expressions, decreased Bax expressions, and decreased caspase-3 enzyme activity. Conclusions : These results show that the red ginseng and paeonia radix mixture exerts a protective effect against SNP-induced apoptosis in SK-N-MC cells.

Fludarabine, a chain terminating anti-cancer drug, is a purine analogue that causes DNA strand breaks in normal cells. In this study, we determined if A. melanocarpa and Korean red ginseng extract mixture reduce cytotoxicity of fludarabine. Treatment of HaCaT cells with $10{\mu}M$ of fludarabine for 24 hours decreased cell viability and increased DNA strand breaks. Treatment of A. melanocarpa and Korean red ginseng extract mixture for 24 hours increased cell viability as compared with single extract treatment. The protective effect of these extracts on cell activity increased in a concentration-dependent manner. DNA strand breaks induced by fludarabine decreased as concentration of extract mixture increased. p-H2AX level, a marker of DNA strand breakage, decreased depending on the concentration of extract mixture. The effect of mixed extract of A. melanocarpa and Korean red ginseng on DNA damage is due to the anti-oxidative effect of A. melanocarpa and signal transmission through glucocorticoid receptor upon binding of saponin of Korean red ginseng.

본 시험은 흑홍삼이 함유된 혼합물의 숙취해소효능을 확인하기 위해 수행하였다. 효소원을 이용한 혼합 재료들 간의 ADH와 ALDH의 활성은 시중에 판매되고 있는 타사 비교군에 비해 현저히 높은 값을 보였다. 그리고 알코올을 투여하여 숙취를 유도한 시험동물의 혈중 에탄올의 양과 아세트알데히드의 양을 측정하여 생체 내 알코올 분해효능을 평가한 결과, 흑홍삼혼합물을 섭취한 군에서 알코올 투여 1시간 후부터 에탄올의 양은 숙취유도군에 비해 월등히 낮았으며, 시간이 지날수록 농도 의존적으로 에탄올의 양이 감소하였다. 주요 숙취 증상을 야기하는 아세트알데히드의 양은 숙취유도군에서 시간이 지날수록 증가한 반면, 흑홍삼혼합물 섭취군은 알코올 섭취 1시간 후부터 증가하였다가 시간이 지날수록 빠르게 감소함을 확인하였다. 또한 흑홍삼혼합물이 알코올분해효소의 활성에 미치는 영향을 알아보기 위해 간 조직을 분리해 ADH와 ALDH의 활성을 측정한 결과, 흑홍삼혼합물을 섭취한 군이 타사 비교군에 비해 높은 활성을 보임을 확인하였다. 이상의 시험결과로 보아 흑홍삼 혼합음료는 혈중 에탄올의 흡수를 지연시킬 뿐 아니라, ADH와 ALDH의 활성을 증가시켜 혈중 에탄올과 아세트알데히드의 농도를 효과적으로 감소시켜 숙취해소 음료로 이용이 가능하리라 기대된다.

This study was designed to investigate the synergetic hepatoprotective effects from a mixture of Korean Red Ginseng and Pueraria Radix on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity in mice. Liver toxicity was induced by intraperitoneal administration of $CCl_4$ (0.6 mg/kg) in 12 groups of ICR mice. The negative control group was given $CCl_4$ without test samples and the normal group was given no treatment. Among treatment groups, the RGAP treatment (Korean Red ginseng acetic acid extract : Pueraria radix water extract, w/w, 38.4:57.6) decreased $CCl_4$-elevated ALT (101.60 IU/L), AST (833.89 IU/L), and LDH (365.02 IU/L) levels in the serum, and increased the SOD (11.03 unit/mg protein) and CAT (0.37 unit/mg protein) levels and the LPO levels ($59.09{\mu}M/g$ tissue) more than that in the mice group with $CCl_4$-induced control group hepatotoxicity. These results suggest that administration of a mixture of Korean Red ginseng and Pueraria radix decreases $CCl_4$-induced liver damage and enhances antioxidant activity in mice and imply that administration of the mixture in a certain ratio is more effective than single administration of either Korean Red ginseng or Pueraria radix alone.

Chemical studies of nitrogen compounds of Panax ginseng seem relatively rare, Probably due to the isolation difficulties, subsequently the investigations of biological activities are little. The experimental conditions were established for highly complete extraction of peptides (basic, acidic and neutral) from Panax ginseng. This task was achieved by applying the follow isolation procedure: 1 , the sequential extraction with water, 0.1% TFA in 20% acetonitril and buffer pH 6.5 (water-pyridine-acetic acid 100:3:900) : 2, fractionation by ultrafiltration : 3, n-butanol extraction 4, cation- and anion-exchange chromatography : 5, chromato-electrophoresis. The comparison of red ginseng (xylem Sl pith part) and red ginseng inside white (xylem Sc pith part) was also provided. To analyze the peptide mixture the chromato-electrophoresis method of separation was applied. Optimal conditions for peptides mapping of sample were explored. Our experiments revealed the quantitative difference of peptide between xylem & pith and phloem & cortex part. We have also found the qualitative difference in the composition of polypeptides between normal red ginseng (xylem Sc pith part) and red ginseng inside-white (xylem St pith part)

A study was designed to investigate the sorption characteristics of binary mixture of red ginseng powder and maltodextrin(DE-17) or lactose stored at various relative humidities ranging from 52% to 93%. At low relative humilities below RH 67%, the sorption equilibrium was easily achieved, whereas at higher relative humidity values over 75%, all of the mixtures tended to absorb moisture continuously with an increase in storage time. A linear equation of log(dw/dt): a log(t)+ log b was found to be valid between the sorption rate and storage time with respect to storage humilities. A linearity was also found between log(1-Aw) and the amount of water absorbed over the Aw range of 0.52∼0.93 and the slope was affected by the kind of sugar added with that of red ginseng powder and maltodextrin mixture being the smallest.

To develop a ginseng wine, the brewing conditions and sensory evalution of the wine were studied. The ginseng, ginseng marc and red ginseng marc can be made into wine by ethanol fermentation with Saccharomyces cerevisae. The results showed that the higher ginseng concentration was, the faster the brewing velocity became. The ginseng marc wine brewed with 10% ginseng marc and 25% sugar was a great favorite The results from the mixture of ginseng and ginseng marc revealed that the mute the content of ginseng was, the faster the velocity of brewing became. It took 27 days for a wine from 10% ginseng marc to be brewed Into 12% ethanol, 10% ginseng took 10days and red ginseng took 15 days. Among these, a wine from 10% ginseng was superior to others in flavor, color and taste. And the wine from 6.7% red ginseng was favorite. Contents of the favorite wine from ginseng marc were 80mg/ml of reducing sugar, 2.6 of acidity, 12% of ethanol, 28mg/ml of saponin, and it's pH was 3.5. Contents of the favorite wine from red ginseng marc were 58mg/ml of reducing sugar, 2.8 of acidity, 12% of ethanol, 44mg/ml of saponin, and it's pH was 2.8.

Currently, injuries to customers due to health functional foods are annually increasing. To evaluate the antigenicity of Korean red ginseng mixture (KRGM), we tested for systemic anaphylactic shock and passive cutaneous anaphylaxis in guinea pigs. Based on a comparison of measured body weights, there were no changes in body weight for the KRGM treatment group compared with the control group. In the ovalbumin treated group, however, there was a statistically significant decrease in body weight. For the active systemic anaphylaxis test, after the induction, there were no symptoms that suggested anaphylactic shock in the control and KRGM treatment group. In the ovalbumin treated group, there were symptoms that suggested severe anaphylaxis, and those symptoms included restlessness, piloerection, tremor, rubbing or licking the nose, sneezing, coughing, hyperpnea, dyspnea, staggering gait, jumping, gasping and writhing, convulsion, side position and Cheyne-stokes respiration. All animals died within thirty minutes in the ovalbumin treated group. For the passive cutaneous anaphylaxis test in guinea pigs sensitized to KRGM, each anti-serum was diluted in a stepwise manner. This was followed by an intravenous injection of a mixture of KRGM and Evans blue. The results of the test showed that all the responses were negative in the control and the low-dose and high-dose administration groups. However, in the ovalbumin treated group, all the responses were positive. Based on the above results, there were no anaphylactic responses for up to 12 times the amount of human intake of KRGM in Hartley Guinea-pigs. The results suggest that KRGM is safe as measured by the systemic and local antigenicity in guinea pigs.

In this study, rat hepatocytes known to have active carbohydrate metabolism were obtained by using the liver perfusion technique to examine the hypoglycemic action of red ginseng saponin components [ginsenoside (mixture, $Rb_1$, and $Rg_1$)] and incubated in two different media-one containing insulin and glucagon (control group), and the other containing glucagon only, The specific activities of some regulatory enzymes such as glucokinase, glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and glucose 6-phosphatase, in main pathways which were directly related to the glucose metabolism were compared between these two kinds of hepatocytes cultured in two different media. The effects of red ginseng saponin components [ginsenoside (mixture, $Rb_1$, and $Rg_1$)] under the concentration of $10^3$~$10^6$% on these enzymes In hepatocytes were also investigated, when they were added to these two media. The results were as follows. The specific activity of enzymes such as glucokinase, glucose 6-phosphate dehydrogenase, and 6-phosphogluconate dehydrogenase related to glucose-consuming pathways of insulin-deficient group was much less than control one, however, their decreased activity was recovered after the addition of ginseng components at all range of concentrations. The increased specific activity of these on - zymes was shown by the addition of ginseng components to the control group. On the other hand, the specific activity of glucose 6-phosphatase related to glucose-producing pathway of insulin-deficient group was much higher than control one, but their Increased activity was decreased after the addition of ginseng components at all range of concentrations. The same results were obtained after the addition of ginseng components to the control group. These results suggest that the red ginseng saponin components might better diabetic hyperglycemia by regulating the activity of enzymes related to glucose metabolism directly and/or Indirectly though more detailed studies were needed.
