Vaccination is the main strategy for preventing influenza infection. However, vaccine efficacy is influenced by several factors, including age and health status. The efficacy of the influenza vaccine is much lower (17% to 53%) in individuals over 65 yr of age compared with young adults (70% to 90%). Therefore, increasing vaccine efficacy remains a challenge for the influenza vaccine field. In this study, we investigated the impact of supplementing vaccination with the dietary intake of Korean red ginseng (RG) extract and RG saponin. Mice were immunized two times intranasally with inactivated influenza A (H1N1) virus. Mice received RG extract or RG saponin orally for 14 d prior to the primary immunization. After the primary immunization, mice continued to receive RG extract or RG saponin until the secondary immunization. Mice vaccinated in combination with dietary intake of RG extract and RG saponin showed elevated serum anti-influenza A virus IgG titers and improved survival rates in lethal influenza A virus infection: 56% and 63% of mice receiving RG extract or RG saponin survived, respectively, while 38% of mice that only received the vaccine survived. Moreover, mice receiving RG extract supplementation recovered their body weight more quickly than those not receiving RG extract supplementation. We propose that the dietary intake of RG extract and RG saponin enhances the vaccine-induced immune response and aids in providing protection against influenza virus infection.

Ethanol exerts different effects on hepatic cellular metabolism, depending mainly on the duration of its intake. In the presence of ethanol following an acute load, a number of hepatic functions are inhibited, including lipid oxidation and microsomal drug metabolism. In its early stages, chronic ethanol consumption produces adaptive metabolic changes in the endoplasmic reticulum which result in increased metabolism of ethanol and drugs and accelerated lipoprotein production. Prolongation of ethanol intake may result in injurious hepatic lesions such as alcoholic hepatitis and cirrhosis A number of such metabolic effects of ethanol are directly linked to the two major products of its oxidation; hydrogen and acetaldehyde. The excess hydrogen from ethanol unbalances the liver cell's chemistry. In the presence of excess hydrogen ions the process is turned in a different direction. In this study, it was attempted to observe the effect of ginseng saponins on alcohol Oehydrogenase(ADH), aldehyde dehydrogenase(ALDH) and microsomal ethanol oxidizing system(MEOS) in vivo as well as in vitro. Furthermore, the effect of ginseng saponin on the hydrogen balance in the liver and the hepatic cellular distribution of (1-14C) ethanol, its incorporation into acetaldehyde and lipids was also investigated. It seemed that ginseng saponin stimulated the above enzymes and other related enzymes in ethanol metabolism, resulting in a rapid removal of acetaldehyde and excess hydrogen from the animal body,

Previously we have reported that black ginseng was produced by nine-time repeated steaming 5-year fresh ginsengs at 95${\circ}$C for 3hr in pottery apparatus and drying at 60${\circ}$C for 12${\sim}$36 hr and had an outstanding anticancer activity. This study was designed to examine the ability of black ginseng to suppress body weight gain appetite, and to investigate the effect of black ginseng on lipid profile in male rats fed normal diets. The extract of black ginseng was administered daily for 3 weeks, and the changes of body weight and food intake were measured. After administering the extracts for 3 weeks, the fat weight and serum lipid levels were also measured. Black ginseng persistently suppressed weigh gain and food intake was also reduced, but not significantly; The weight of both epididymal and abdominal fats was decreased In black ginseng-treated rats. Serum triglyceride level in rats administered with black ginseng was also significantly lowered. Therefore, these results reveal that the repeated administration of black ginseng causes a suppression of body weigh gain by decreasing triglyceride level in blood and body fat deposit.

Tow groups of subjects were studied before, during, and after long-term use of commercial Panax ginseng preparations. Group A (n = 10) consisted of users who also used other psychomotor stimulants including caffeine, while subjects in Group B (n = 8) used no drugs other than ginseng. During 12 weeks of regular ginseng use, users in Group A showed signs of central nervous system stimulation and reported feelings of well-being. Two subjects manifested possible allergic reactions while one developed a ginseng abuse syndrome marked by hypertension, nervousness, sleeplessness, skin eruptions, edema, and morning diarrhea. This syndrome was associated with excessive dosages, concomitant intake of caffeine, and possible allergic reactions. Subjects in Group B reported stimulation and feelings of well-being while showing some signs of nervousness. One subject developed a possible contact urticarial reaction to a ginseng cosmetic. All adverse reaction were transient and disappeared when ginseng use was discontinued. It is suggested that adverse reactions can be prevented by moderate use of standardized ginseng preparations while restricting use of other psychomotor stimulants.

We have found many beneficial effects of the long-tenn intake of Korean red ginseng (KRG) in human immunodeficiency virus (HIV) type-I infected patients, including the maintenance of CD4+ T cell count for 10 years with KRG only and the delayed development of resistance mutation to ZDV. In this study, to investigate whether KRG-intake could affect the clinical progression and nef gene variation, we determined 200nef sequences from 70 patients. Follow-up period was $8.8{\pm}2.9$ years and annual decrease in CD4+T cell was $41{\pm}57/ul.$ Nested polymerase chain reaction (PCR) and direct sequencing were perfonned with peripheral blood mononuclear cells (PBMC) obtained at times during the study period. First, there was a significant correlation between survival duration and duration of KRG-intake $(36.8{\pm}38$ months)(P=0.000). There were significant correlations between the last NefProg score and CD4+ T cell count (r= 0.208, P<0.05) and annual decrease in CD4+ T cell count (r =0.346, P<0.01) in 70 patients. In addition, there were significant correlations between KRG-intake and annual decrease (r= 0.323, P<0.01), and the CD4+ T cell count itself (r=0.229, p<0.05). Furthennore, there was also a mild significance between the NefProg score and the duration of KRG-intake in only SP and RP (n=30, r=-0.281, P=0.067). In addition, we detected various defects in 21 patients $(30.0\%),$ not including 5 premature stop codons. Ten $(12.5\%)$ patients showed repeated deletion of an amino acid. Four of 10 patients were gross deletions and they were treated with KRG for more than 20 months. The number of patients with repeated gross deletions was significantly higher in the order of slow progressors $(18\%)$, typical progressors($3\%$), and rapid progressors($0\%$) (P<0.05). We also observed that long-tenn intake of KRG might make the change from A or D to T at position 54 and decrease NefProg score. Taken together, our results show clear evidence that the long-term intake of KRG has effects on nef gene variation as well as definite clinical usefulness.

This study was conducted to investigate the application possibility of leaf and stem extract(LSE) extracted from the mixture of leaf and stem of ginseng radix(Panax ginseng CA. Meyer). This study measured the intake levels and efficiency ratio, growth rate, absorption ratio of carbohydrate, lipid and protein of rat by feeding with LSE during 6 weeks. We analyse the hematological and serum metabolic variables, serum lipid concentrations. Total diet and protein intake levels were low, but efficiency ratios were significantly high in LSE administered groups than the control group. Weight gain, liver and kidney weight of LSE groups were significantly higher than the control group. Blood RBC, Hct, Hb, total protein and albumin concentrations were reasonable levels in LSE administered groups compared to the basal diet group. Also serum total cholesterol, LDL-cholesterol, triglyceride contents of LSE groups were low, but HDL-cholesterol level was higher than the basal diet group. These results imply that leaf and stem of ginseng radix could be used as possible food resources, functional food material and feed stuff.

The aim of this study was to evaluate the efficacy of red ginseng drinks as school meal drinks for 456 middle and high school students in Cheongdo-gun, North Gyeongsang Province. In preliminary studies, we focused on saponin with an efficacy of Rg 1 and Rg 2 in prepared red ginseng drinks. The health benefits and sensory characteristics were also investigated. For the frequency analysis, the satisfaction of the drinks as beverages serving as a school meal was relatively low, and the demand for fruit drinks was high. The result of sensory evaluations indicated a positive response of > 50.0% for the container packaging and design, daily intake, and tastes. Regarding the correlation analysis on red ginseng drinks, there were significant differences (p < 0.01) in the response to packaging (a daily intake) and design. In addition, health and learning benefits showed a very high correlation at the p < 0.01 significance level.
