In this study, cell cracker method as a non-collision method was evaluated for the possibility in manufacturing red ginseng powder. In color value of red ginseng powder, the L values indicating brightness were 68.18 for hammer mill (group A) and 72.08 for cell cracker (group B). The a values (redness) and b values (yellowness) were 4.21 26.56 for group A and 5.73, 28.36 for group B, respectively. As an extraction time increased, the absorbances at 420 nm of water extract of both groups were increased. In the loose bulk density, tapped bulk density and volume reduction radio indication the of powder in group A were less than those in group B. In both groups, the angles of side of red ginseng powder were shown less value than the angles of side of the powder. These two angles in group A were lets than those in group B. In sensory evaluation, the touchness between both groups was, not observed significant difference. In the contrary, the color and flavor, main factors affecting the overall quality of red ginseng powder product of group B were shown superior to those of group A. The overall preference of group B was shown higher than that of group A.

Radioprotective effects of a red ginseng extracts on antioxidant enzymes(Superoxide dismutase, catalase and peroxidase) activities relationship to lipid peroxidation were studied in the cytosol fraction of mice liver. The experiments were carried out on Irradiated (5.5 Gy, $^{\60}Co$) and non-irradiated ICR mice after treatment of red ginseng extracts (5.5mg/mouse ; ip), In wholebody irradiated mice, irradiation caused a decrease in the activity of all these enzymes(on Day 21) The activities of SOD, Catalase and Peroxidase of red ginseng extracts treated mice were enhanced by $35.4\%,\;20.2\%$ and $20.1\%$, compared with non-treated mice. The red ginseng extracts led to inhibited increase of malondialdehyde product by ionizing radiation. The enhanced activity of enzymes that removed free radicals generated by radiation and thereby indicate that ginseng probably plays on important role in radioprotective effect.

Cylindrocarpon destructans is the major pathogen inducing the root rot disease in ginseng. Up to now, there is no reliable and convenient method to analyze the spore density or population of this pathogen in ginseng-growing soil or any contaminated farmlands. Therefore, it will be very valuable to develop a new and reliable method in detecting the spore of this pathogen. In this study, a molecular biological technique using two step nested PCR method, was developed. Two universal ITS primers, ITS5F and ITS4R were used in the first round of PCR to amplify a fragment of ITS region from the genomic DNA of C. destructans. The specific prmers Nest 1 and Nest 2 were designed and used in the second round of PCR to amplify a inner fragment from the first round PCR product of C. destructans. C. destructans spore, only soil samples from the diseased ginseng farm produced the positive bands, suggesting its usefulness in detecting the C. destructans spores in soil samples. Thus it is recommended to first extract the whole genomic DNA from soil samples and use it for the PCR reaction, thereby eliminating the inhibitory activity of soil components.

Background: The present study investigated the effect of ginseng berry hot water extract (GBx) on blood flow via the regulation of lipid metabolites and blood coagulation in rats fed a high-fat diet (HFD). Methods: Sixty rats were divided into five groups in descending order of body weight. Except for the control group, the other four groups were fed a HFD containing 45% kcal from fat for 11 wk without GBx. GBx groups were then additionally treated by gastric gavage with GBx dissolved in distilled water at 50 (GBx 50) mg/kg, 100 (GBx 100) mg/kg, or 150 (GBx 150) mg/kg body weight for 6 wk along with the HFD. To investigate the effects of GBx on rats fed a HFD, biochemical metabolite, blood coagulation assay, and histological analysis were performed. Results: In the experiments to measure the serum levels of leptin and apolipoprotein B/A, GBx treatment attenuated the HFD-induced increases in these metabolites (p < 0.05). Adiponectin and apolipoprotein E levels in GBx-treated groups were significantly higher than the HFD group. Prothrombin time and activated partial thromboplastin time were increased in all GBx-treated groups. In the GBx-treated groups, the serum levels of thromboxane $A_2$ and serotonin were decreased and concentrations of serum fibrinogen degradation products were increased (p < 0.05). Moreover, histomorphometric dyslipidemia-related atherosclerotic changes were significantly improved by treatment with GBx. Conclusion: These results suggest the possibility that GBx can ameliorate blood flow by decreasing intima-media thickness via the regulation of blood coagulation factors related to lipid metabolites in rats fed a HFD.

Background: In previous work, we reported that Korean Red Ginseng saponin fraction (RGSF) showed anti-inflammatory activities in vitro and in vivo. Methods: The present study investigated the radioprotective properties of RGSF by examining its effects on ionizing radiation (IR)-enhanced and lipopolysaccharide (LPS)-mediated inflammatory responses in murine macrophage cells. Results: RGSF induced strong downregulation of IR-enhanced and LPS-induced proinflammatory responses such as nitric oxide (NO) production (Inhibitory Concentration $50(IC_{50})=5.1{\pm}0.8{\mu}M$) and interleukin-$1{\beta}$ levels. RGSF was found to exert its radioprotective effects by inhibition of a signaling cascade that activated checkpoint kinase 2enuclear factor-${\kappa}B$. In addition, RGSF strongly inhibited IR-enhanced LPS-induced expression of hemoxyganase-1, implying that the latter may be a potential target of RGSF. Conclusion: Taken together, our data suggest that RGSF can be considered and developed for use as an effective radioprotective agent with minimal adverse effects.

Objectives: Reactive Oxygen Species(ROS) are continuously produced at a high rate as a by-product of aerobic metabolism. Since tissue damage by free radical, ROS such as hydrogen peroxide($H_2O_2$), nitric oxide(NO) increases with age. Several lines of evidence provided that ROS appears to cause to develop aging-related various diseases such as cancer, arthritis, cardiovascular disease. In this study, we have conducted to investigate the pharmacological effects of red ginseng for the development possibility to pharmacopuncture drug sources or healthy aid foods. Methods: For our aims, it was investigated the biological activities of Red Ginseng ethanol extracts (RGEE) by measuring total polyphenol contents, total flavonoid contents, DPPH radical scavenging activity, ABTS radical scavenging activity and cell viability of MCF 10A and SK-MEL-2 in vitro with MTT assay method. Results: The total polyphenol contents of RGEE was 3.06${\pm}$0.11mg/g in 10mg/ml, the total flavonoid contents of RGEE was 1.35${\pm}$0.01mg/g in same concentration. The ABTS radical scavenging activity was about 80% and that of DPPH activity was 65% in 50mg/ml of RGEE. The cell viability of SKMEL-2, skin cancer cell line was decreased and that of MCF 10A, skin normal cell line was increased. Conclusions: We conclude that RGEE may be useful as potential functional foods or pharmacopuncture drug sources on the diseases induced by oxidant stress.

The aim of this study was to investigate the effect of face wash with ginseng cold process (CP) soap. In order to remove external environmental factors, skin changes were examined immediately after 10 minutes of face wash. The same water and towel were used at the same place. As a control group, the cases of washing with water without using cleanser and with foam cleanser (F/C), which is a popular commercial product, were set. In the case of water washing, there was a significant decrease in pores and pigmentation, but the significance was small. In the case of F/C washing, there was a very significant decrease in pores and pigmentation, but the loss of moisture was rapid. In the case of ginseng cp soap, pores and pigmentation were significantly reduced, while moisture loss was negligible. Ginseng cp soap is considered as a form of face wash that is suitable for skin care.

Background: Di-(2-ethylhexyl) phthalate (DEHP) is the most common endocrine disrupting chemical used as a plasticizer. DEHP is associated with the development of endometrium-related diseases through the induction of inflammation. The major therapeutic approaches against endometrial cancer and endometriosis involve the suppression of inflammatory response. Korean Red Ginseng (KRG) is a natural product with anti-inflammatory and anti-carcinogenic properties. Thus, the purpose of this study is to investigate the effects of KRG on DEHP-induced inflammatory response in endometrial cancer Ishikawa cells and a mouse model of endometriosis. Methods: RNA-sequencing was performed and analyzed on DEHP-treated Ishikawa cells in the presence and absence of KRG. The effects of KRG on DEHP-induced cyclooxygenase-2 (COX-2) mRNA levels in Ishikawa cells were determined by RT-qPCR. Furthermore, the effects of KRG on the extracellular signal-regulated kinases (ERKs) pathway, COX-2, and nuclear factor-kappa B (NF-kB) p65 after DEHP treatment of Ishikawa cells were evaluated by western blotting. In the mouse model, the severity of endometriosis induced by DEHP and changes in immunohistochemistry were used to assess the protective effect of KRG. Results: According to the RNA-sequencing data, DEHP-induced inflammatory response-related gene expression was downregulated by KRG. Moreover, KRG significantly inhibited DEHP-induced ERK1/2/NF-κB/COX-2 levels in Ishikawa cells. In the mouse model, KRG administration significantly inhibited ectopic endometriosis growth after DEHP-induced endometriosis. Conclusions: Overall, these results suggest that KRG may be a promising lead for the treatment of endometrial cancer and endometriosis via suppression of the inflammatory response.
