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.

This study was performed to investigate the effect of red ginseng extract including some vitamin B groups as test drug on learning and memory in mice. Single and repeated administrations of the test drug improved the acquisition and the process of consolidation in the tests using step-through and step-down apparatus, indicating this test drug improved learning and memory. However, the test drug did not improve scopolamine-induced amnesia. These results suggest that test drug may be useful as a nootropic agent.

Preventive effect of red ginseng saponin on experimentally-induced hyperkeratosis was investigated by ultrastructural observation, skin weight and epidermal lipid analysis. Hexadecane increased skin weight per unit area and epidermal lipids, free fatty acids, cholesterol and triglyceride in guinea pig skin. Topical application of ginseng saponin reduced these hyperkeratotic responses regradless of the concentration and the purity of ginseng saponin. Ultrastructurally, lipids and empty space-containing multiple horny cells were piled and nuclear remnants, desmosome, desmosomal bodies, tight junction were shown in the stratum corneum of hexadecane-treated skin.

In an attempt to explore the effect of Ginseng on the permeability of the biological membrane to cations we have investigated the effect of Ginseng-alcohol extract on the transport of $Na^+$ human red blood cell preprations. The $Na^+$ influx was measured in intact red cells using $^{22}Na$ as a tracer and the efflux in reseated red cells using $^{24}Na$ as a tracer. 1. The influx of $Na^+$ was not apparently changed by the Ginseng-alcohol extract of 20mg% in the incubation medium. 2. Similarly, 20mg% Ginseng-alcohol extract in the cellular space did not alter the efflux of $Na^+$ from the cell. However, 50mg% of Ginseng-alcohol extract in the cell resulted in a significant increase in the $Na^+$ efflux and this effect was magnified when the cell was suspended in the medium containing the Ginseng-alcohol extract in a concentration of 20mg %. The results suggest that Ginseng-alcohol extract over 50mg% increase permeability of red blood cell membrane to $Na^+$ by altering the membrane integrity.

Korean Red Ginseng (KRG) is a heat-processed ginseng developed by the repeated steaming and air-drying of fresh ginseng. Compared with fresh ginseng, KRG has been shown to possess greater pharmacological activities and stability because of changes that occur in its chemical constituents during the steaming process. In addition to anticancer, anti-inflammatory, and immune-modulatory activities, KRG and its purified components have also been shown to possess protective effects against microbial infections. Here, we summarize the current knowledge on the properties of KRG and its components on infections with human pathogenic viruses such as respiratory syncytial virus, rhinovirus, influenza virus, human immunodeficiency virus, human herpes virus, hepatitis virus, norovirus, rotavirus, enterovirus, and coxsackievirus. Additionally, the therapeutic potential of KRG as an antiviral and vaccine adjuvant is discussed.

온도와 시간을 달리하여 홍삼박을 볶음처리하여 얻은 분말과 수용성 추출액의 향기성분과 관능적 특성을 분석한 결과, $200^{\circ}C$에서 20분간 처리하였을 때 무처리 분말보다 정유성분의 양이 많았고, 향기성분은 7종의 pyrazin계 화합물을 비롯하여 29종의 화합물이 확인되었다. Panel에 의해 평가된 관능적 향미는 무처리구인 홍삼박 분말에서는 흙 냄새, 묵은 쌀 냄새, 비린내, 마른나무 냄새가 강하였으나, 볶음처리한 분말에서는 탄내, 구수한 냄새가 강하게 평가되었다. 볶음처리한 분말 $5\%$용액의 향은 무처리구에서는 비린내가 강하였으나, 처리구에서는 향기로운 냄새, 탄내, 누룽지 냄새, 마른나무 냄새가 강하였으며 비린내는 매우 약하게 평가되었다. $200^{\circ}C$에서 20분간 처리구에서 특히 커피와 같은 향미, 개운한 맛, 누룽지 냄새가 강했고, $2.5\%$ 용액에서는 개운한 맛, 떫은 맛이 강한 것으로 평가되었다. 볶음처리 시 생성된 이들 향미성분은 유리당과 aiginine함량의 급격한 감소에 의한 것으로 생각된다.

This study was conducted to determine the effects of mixed Korean red ginseng marc with aluminum sulfate on gas concentration and volatile fatty acid (VFA) in poultry litter during 4 weeks in terms of livestock and environment managements. A total of 240 broiler chicks were randomly allocated to four treatments in four replications and 15 birds per replicate. The four treatments was mixed to rice hull under each pen at 0, 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate per kg poultry litter (rice hulls). Carbon dioxide, methane, acetic acid, and propionic acids were measured weekly. The results that could be available include: First, during the experimental period, carbon dioxide emissions were not remarkably different among treatments. Second, no differences were observed among treatments in methane emissions at 2 weeks through 4 weeks, but at 1 week, the reduction in methane emissions was in following order: 100 g aluminum sulfate > 20 g red ginseng marc + 90 g aluminum sulfate > 10 g red ginseng marc + 90 g aluminum sulfate > control. Third, in spite of statistically differences, treatment with 10 g or 20 g red ginseng marc + 90g aluminum sulfate, and 100g aluminum sulfate reduced acetic acid and propionic acid as a function of time, except acetic acid in aluminum sulfate treatment at 2 and 4 weeks. In conclusion, the results indicated that like aluminum sulfate, using 10 g or 20 g red ginseng marc with aluminum sulfate was effective in decreasing methane and propionic acid released from poultry litter.

Using an ethopharmacological technique, we demonstrated that saponin fraction from red ginseng root possessed a potent psychotropic actions on either intermale or maternal aggression models. A series of experiments clearly indicated that one of psychoactive ingredient is ginsenoside Rbl. Although a drug-induced debilitation of motor performance remains a possible cause of the antiaggressive effect of the drug, ginsenoside Rb 1 did not alter the locomotor activity of the mice during agonistic confrontations. Thus, one can eliminate the possibility that the psychoactive effect of ginsenoside Rbl might be concealed by a drugindulced impairment of motor performance. More recently, we developed a new model for copulatory disorder and introduced into the behavioral analysis of drug action. Male mice which has been housed individually from weaning for 5 weeks failed to manifest copulatory behavior when they encountered with the sexually-receptive females. Daily administration of crude ginseng saponin during isolation housing period prevented the development of copulatory disorder, whereas both ginsenoside Rbl and Rgl were ineffective. A further experiment may be needed to explore active ingredient of ginseng saponins. Keywords Panax ginseng, Korean red ginseng, psychotropic action, saponin, ginsenoside Rb1

In this study we investigated the immune effects of oral administration of anionic macromolecules extracted from Codium fragile (CFAM) and red ginseng extract mixture on the peritoneal macrophage cells in immune-suppressed mice. Cyclophosphamide (CY) induces the immune-suppressed condition. CY-treated mice were orally fed with different concentrations of CFAM supplemented with red ginseng extract and the peritoneal macrophages collected. CY treatment significantly decreased the immune activities of peritoneal macrophages, compared to the normal mice. The administration of CFAM mixed with red ginseng extract significantly boosted the viability of macrophage cells and nitric oxide production of peritoneal macrophages. Further, the oral administration of CFAM mixed with red ginseng extract up-regulated the expression of iNOS, COX-2, and TLR-4 as well as cytokines such as IL-1β, IL-6, TNF-α, and IFN-γ more than the red ginseng-treated group. This study showed that CFAM enhanced the immune activity of red ginseng extract in the peritoneal macrophage cells of immune-suppressed mice. Furthermore, CFAM might be used as a co-stimulant of red ginseng extract through the regulation of macrophage cells for the enhancement of human health and immunity.
