Sulgidduk samples containing 2, 4, and 8% red ginseng powder and a control[ED highlight - consider specifying what the control was, if 0%, then change to Sulgidduk samples containing 0(control), 2, 4 and 8%] were examined for moisture content, color, gelatinization properties, textural characteristics, and sensory qualities to determine the optimal ratio of red ginseng powder in the formulation. The moisture contents among the samples did not differ significantly. Specifically, they ranged from 39.64 to 40.69%, and increased as the red ginseng powder content increased. Additionally, the lightness decreased and the yellowness and redness increased as the red ginseng powder content increased. Evaluation of the gelatinization properties revealed that the, peak viscosity(P), hold viscosity(H), final viscosity(F), setback, and time to peak viscosity decreased with increasing red ginseng powder content, but the breakdown and temperature to peak viscosity did not differ significantly among samples[ED highlight - please ensure my changes are correct]. The hardness and adhesiveness decreased with increasing red ginseng powder content, as did the cohesiveness, gumminess, and chewiness; however, the springiness did not differ significantly among samples. Sulgidduk containing 4% red ginseng received the highest scores for flavor, taste, texture and overallquality. Based on the above results of the sensory and texture analyses, Sulgidduk containing 4% red ginseng had the highest quality[ED highlight - please ensure my changes are correct].

Dry rehydratable film (Petrifilm) method was compared with the standard pate count (SPC) method for estimation of total bacteria in ginseng products. Ginseng products (7 sample) was analyzed for total count by the SPC, and Petrifilm methods, respectively. In the case of ginseng tea, ginseng extract, ginseng extract pill, ginseng powder capsule, and ginseng extract tea, they showed non-significant values at the 1% level. However, the values of ginseng powder and tablet showed significant at the 1% level. These results generally indicate the suitability of the dry rehydratable film methods as alternatives to the SPC method for estimating of total bacteria in ginseng product samples except to ginseng powder and ginseng tablet.

Background: Some phenolics detected in the soil may inhibit the seed germination and seedling growth of ginseng (Panax ginseng). This study investigated the effect of irrigation and ginseng root residue addition on the soil microbial community and root rot disease in 2-year-old ginseng. Methods and Results: Each $20{\ell}$ pot was filled with soil infected with ginseng root rot pathogens, and irrigated daily with $2{\ell}$ of water for one month. After the irrigation treatment, ginseng fine root powder was mixed with the irrigated soil at a rate of 20 g per pot. In descending order, ${NO_3}^-$, electric conductivity (EC), exchangeable Na (Ex. Na) and K (Ex. K) decreased due to irrigation. In descending order, ${NO_3}^-$, EC, Ex. K, and available $P_2O_5$ increased with the additon of ginseng powder to the soil. The abundance of Trichoderma crassum decreased with irrigation, but increased again with the incorporation of ginseng powder. The abundance of Haematonectria haematococca increased with irrigation, but decreased with the incorporation of ginseng powder. The abundance of Cylindrocarpon spp. and Fusarium spp., which cause ginseng root rot, increased with the incorporation of ginseng powder. The abundance of Arthrobacter oryzae and Streptomyces lavendulae increased with irrigation. The abundance of Streptomyces lavendulae decreased, and that of Arthrobacter spp. increased, with the incorporation of ginseng powder. Aerial growth of ginseng was promoted by irrigation, and ginseng root rot increased with the incorporation of ginseng powder. Conclusions: Ginseng root residues in the soil affected soil nutrients and microorganisms, and promoted ginseng root rot, but did not affect the aerial growth of ginseng.

The present study was carried out to evaluate the effect of Panax ginseng on the metabolism of nonprotein nitrogen compounds in rabbit blood. After rabbits were administered with ginseng powder orally for 30 days or with ginseng extract intraperitoneally for 10 days, the blood was collected from portal and ear vein to measure ammonia, urea, creatinine and nonprotein nitrogen. The blood ammonia level in ear vein of control rabbits was $87.0{\pm}5.1{\mu}g/100ml$ and was not significantly different from that of rabbits which were administered with ginseng powder orally or with ginseng extract intraperitoneally. But oral administration of ginseng powder produced a great decrease in ammonia level of portal vein from 1,392 to $704{\mu}g$ per 100ml, suggesting that intestinal ammonia production is suppressed by ginseng powder due to its antimicrobial activity. While there was no significant difference between the control and the rabbits which were administered with ginseng extract intraperitoneally. Ginseng administration had no effect on the creatinine level in blood from ear and portal vein, except the intraperitoneal injection of ginseng extract. It slightly lowered the creatinine level only in ear vein blood. The values of urea and nonprotein nitrogen were net affected by the administration of ginseng.

The aim of this study was to develop rice wine (Yakju) containing various amounts and particle sizes of ginseng powder and to analyze the physicochemical characteristics and content of ginsenosides in ginseng-Yakju. Soluble solid content, pH, ethanol concentration, acidity, amino acid content, and evaluation of preference showed no difference between four kinds of Yakju groups, regardless of ginseng supplementation and particle size of the ginseng powder. During fermentation of Yakju containing ginseng, the contents of ginsenosides Rb1, Rb2, Rb3, and Rc were decreased. Otherwise, the content of ginsenoside Rh1 was increased highly by brewing microorganisms in Yakju. Recovery ratios of ginsenosides in ginseng-Yakju were approximately 25.4% (coarse ginseng power) and 23.8% (fine ginseng powder), which were superior to the recovery ratio of ginsenosides in Yakju containing ginseng slices (5%).

In order to observe the effect of defatted ginseng which is made by extracting fat from ginseng using petroleum ether during the growth and the starvation, the powder of defatted ginseng was added to the basal diet by 25% and 50% respectively, and the mixtures were fed for 4 weeks to just weanling white female rat which weighed 78-82 g. As for the diet initake, there was not showed any meaningful difference between the defatted ginseng powder fed group and the control group (to which was fed just - the basal diet not including defatted ginseng powder), but the protein intake for the former group appeared to be reduced (P<0.02-0.01) compared to the control group. As for the growth rate, that of the defatted ginseng powder fed group appeared higher (P<0.02) than that of the control group in 1 week after feeding, but since after 2 weeks, there was not showed meaningful difference between the two groups. As for the weight-reduction rate by starvation, that of the 25% defatted ginseng powder fed group showed just 79.6% (P<0.05) of the control group's in 5 days after feeding, but the rate of the 50% defatted ginseng powder fed group appeared 119.3% of the control group's. As for the required time from the beginning of starvation to the death, it was resulted that the higher the rate of defatted ginseng addition is, the shorter the time becomes (P<0.05)

Exposure to the sun, ultraviolet radiation, and oxidative stress are the chief etiologic factors responsible for melasma. The ingredients of Korean red ginseng powder, which include ginsenoside and phenolic compounds, have antioxidative effects and reduce ultraviolet B-induced pigmentation. This study was designed to evaluate the effectiveness and safety of Korean red ginseng powder in patients with melasma. In 25 female patients, 3 g of Korean red ginseng powder was orally administered for a 24 week period. The level of pigmentation and erythema were determined and clinical improvement was evaluated by the melasma area and severity index (MASI), melasma quality of life scale (MELASQoL), and patient- and investigator-rated global improvement scale. After 24 weeks, the MASI score decreased from 8.8 to 5.6, and MELASQoL showed improvement in 91% of patients (p<0.05). The mean level of pigmentation decreased from 184.3 to 159.7 and erythema levels decreased from 253.6 to 216.4 (p<0.05). Additionally, 74% of the patients showed some improvement in both patient- and investigator-rated global improvement scales at week 24. Korean red ginseng powder was well tolerated by most of the patients. In conclusion, Korean red ginseng powder showed good tolerability and beneficial effects in patients with melasma. The use of Korean red ginseng would be counted as a useful adjunctive therapy for patients with melasma.
