The experiments were conducted to evaluate the feeding values of red pepper seed (Exp. 1) and to investigate its dietary supplementation on layer performances (Exp. 2). The values of TME, TMEn and average TAAA determined by force-feeding 14 roosters (Hy-line) were 2.83 kcal/g, 2.94 kcal/g and 82.72%, respectively. a total of 200 layers (ISA-brown) was divided into 4 groups with 5 replicates of 10 birds per replicate, and fed the experimental diets containing different level of red pepper seed (0, 3, 5, 10%). There were no differences in performances of laying hens among treatments. Liver lipids in all groups containing red pepper seed were significantly reduced as compared to those of control (P＜0.05).

Exposure to UVB radiation can cause diverse biological photodamage to skin. Eeb 761 and Korean red ginseng are the major and most effective natural drug against a variety of oxidative damage. But, the protective effects against UVB radiation have not been clearly identified. In this study, we investigated the protective effect of topical EGb 761 and Korean red ginseng on pigmentation by UVB radiation. Pro-inflammatory cytokines($IL-l{\beta}$, IL-6 and $TNF-{\alpha}$) and melanogenesis proteins(tyrosinase, TRP-1 and TRP-2) mRNA were measured by reverse transcription-polymerase chain reaction(RT-PCR) analysis. The in vivo protection against pigmentation was calculated using chromameter. The mRNA level of IL-lf and TNF-a were increased by UVB irradiation in treated and non-treated group, while no significant changes were observed in IL-6 level. Topical treatment with EGb 761 and Korean red ginseng remarkably reduced expression of tyrosinase, TRP-1 and TRP-2 in the non-irradiated and irradiated skin. Application of EGb 761 and Korean red ginseng significantly protected the WB-induced skin pigmentation and Korean red ginseng was more effective. Our study suggests that topical ECb761 and Korean red ginseng can regulate melanogenic proteins and protect UVB radiation on skin pigmentation.

In this study, we investigated the effects of 40% ethanol extract of Red Ginseng (RGE) on the productions of inflammatory proteins in Antigen I/II (Ag I/II)-N, a recombinant protein isolated from Streptococcus mutans -stimulated in RAW 264.7 cells. RGE inhibited the expression of Ag I/II-N-induced pro-inflammatory mediators, both mRNA and protein synthesis levels, without any cytotoxic effects. Moreover, RGE significantly inhibited Ag I/II-N induced NF-κB translocation into the nucleus by preventing the degradation of inhibitor κB-α. In conclusion, RGE down regulates the expression of pro-inflammatory genes involved in the synthesis of NO and iNOS in Ag I/II-N-stimulated RAW 264.7 cells by suppressing NF-κB activity.

Objective: This study was performed to determine the apparent metabolizable energy (AME_n) content of tannin-free red/bronze, white/tan and U.S. No. 2 varieties of grain sorghum for feeding Japanese quail and validate their nutrient profile by evaluating effects on performance and carcass traits with full-substitution of corn. Methods: Experiment 1 determined the AME_n content of red/bronze, white/tan, and U.S. No. 2 grain sorghum varieties fed to mixed-sex Japanese quail (Coturnix japonica) (n = 314) at 3 and 6-weeks of age. Analyses were based on a 2×4 factorial treatment design with age and grain types defining the treatments, and a randomized complete block experiment design with cage and trials defining the block. AME_n values were validated by evaluating the performance and carcass traits of Japanese quail (n = 644) from 1 to 40 days of age in Experiment 2 with birds were fed 1 of 4 complete diets. Statistical analyses were conducted on performance data and select individual carcass trait measurements. Results: Determined AME_n values at 3-weeks of age were 3,524±122.03 (red/bronze), 3,252±122.03 (white/tan), and 3,039±123.44 (U.S. No. 2) kcal/kg. At 6-weeks of age, determined AME_n were 3,373±297.35 (red/bronze), 3,279±297.35 (white/tan), and 2,966±298.64 (U.S. No. 2) kcal/kg. Carcass traits showed live body weight (p = 0.0409) and hot carcass weight (p = 0.0234) were greatest in U.S. No. 2; however, carcass yield (p<0.0001) was lowest. No significant differences were observed among treatments for feed intake, feed conversion ratio, breast weight and breast yield (p>0.05). Conclusion: These studies demonstrated that tannin-free grain sorghum varieties may be a potential alternative to corn in quail diets while maintaining growth performance and carcass parameters.

To study the effects of diets containing red Ginseng, rats were fed diets containing various amounts of red Ginseng for 10 weeks. The Ginseng diets were 600 mg of red Ginseng extract concentration, 1,200 mg of red Ginseng powder, 6,000 mg of red Ginseng tea, 3,000 mg of red Ginseng extract concentration, 6,000 mg of red Ginseng extract concentration, 12,000 mg of red Ginseng extract concentration per Kg of diet, and control. As results, growth rate, feed efficiency ratio, organ weight, and hematocrit value showed no statistically significant differences between red Ginseng fed animals and the controls. Serum cholesterol level and GPT were slightly lower in the experimental animals than those in the controls. These differences, however, were not statistically significant. Serum GOT activities for all experimental animals showed no statistically significant except for Group fed with 6,000 mg of red Ginseng extract concentration per Kg diet. This Group revealed significantly lower GOT activities than those of the controls statistically. No abnormalities of liver, spleen, and kidney were observed in the experimental animals.

A study was designed to investigate the effectiveness of Korean Red Ginseng (ERG) as an oral agent for erectile dysfunction (EF), which was compared to that of placebo and trazodone. Patients who were believed to have EF of mild or non-organic etiologies, randomized into 3 groups to receive 600 mg KRG 3 times daily (group A), placebo (group B) and 25mg trazodone once a day after evening (group C). All agents were given orally. Ninety patients, composed of 30 in each group, were included and analyzed only when clinical follow-up could be achieved at the end of the study for at least 3 months. There were no significant differences(p>0.05) between each group in mean age (43.7 years), duration of EF (5.8 years), the state of marriage (married : 80 patients) and duration of marriage (18.2 years). In group A, the parameters such as rigidity and tumescence on erection, early detumescence, libido and patient's satisfaction were significantly more effective than that of other group (p<0.05). But there were no significant differences in the parameters such as the frequency of coitus, premature ejaculation and morning erection between 3 groups (p>0.05). The efficacy achieved with KGR (60%) was significantly higher (p<0.05) than that of placebo (30%) and trazodone (30%). There were no significant changes on level of serum testosterone and type of AVS-penogram in group A. No side effect was demonstrated in all patients.

Purpose: The purpose of this study is to identify the clinical effect of Red Ginseng in the treatment of postmenopausal hot flushes. Methods: We studied 49 women from 45 to 55 years old who complained hot flushes. We randomly divided women into two groups, We treated one group with red ginseng capsule, and treated another group with placebo for 2 months. patients recorded the frequency of the hot flush on an everyday basis. And we measured temperature of patient's face by DITI. Results: Red ginseng and Placebo treated group significantly decreased the frequency of the hot flush. After treatment, the temperature on the cheekbones who treated by red ginseng get lower than before treatment. But there is no statistically difference between red ginseng and placebo. Conclusion: This study shows that both red ginseng and placebo have remarkable effects on patients, but red ginseng is not better than placebo.

Red ginseng is a medicinal herb widely used in East-Asia for a long time. Recently there have been a lot of studies about the effect of red ginseng on the immune responses. We investigated the differences between Korean red ginseng and Chinese red ginseng in the lymphocyte proliferation and cytokine production. The rats were divided into 3 groups, KRG(Korean Red Ginseng) group, CRG(Chinese Red Ginseng) group, and the Control group. Experimental groups were administered with Korean and Chinese red ginsengs for three months respectively. Then we obtained the lymphatic cells from spleen and compared the ability of KRG on the lymphocyte proliferation and the cytokine production after mitogen-stimulated culture to CRG. The proliferation of lymphocyte and level of $IL-1{\alpha}$ were significantly increased only in KRG group. There were significant increases in the level of $INF-{\gamma}$ in both KRG and CRG groups. There were no significant differences in the level of IL-2 and $TNF-{\alpha}$. These results indicate that KRG can induce infection-relevant immune responses much faster and higher than CRG. Furthermore, functional activation of CD8+ T-cell may be activated by red ginsengs.

It was confirmed that complex fermentation (CF) was more efficient than single-strain fermentations in inducing changes in the contents of phenolic compounds of Maclura tricuspidate and Pyrus Montana Nakai. A mixture of Maclura tricuspidata, Pyrus montana Nakai, Platycodon grandiflorum and Codonopsis lanceolata were fermented in CF using Aspergillus shirousamii (koji), yeast, and lactic acid bacteria (LAB) for 24 days, and the pH, °Brix, total acidity, anti-oxidant activity, polyphenol content, nitric oxide (NO), and Western blotting of inducible nitric oxide synthase (iNOS), cyclo-oxygenase-2 (COX-2), and tumor necrosis factor-𝛼 (TNF-𝛼) of the sample were determined. There was no significant change in pH and total acidity. °Brix significantly decreased from day 6 onwards. HPLC confirmed that the concentrations of chlorogenic acid, 4-hydrobenzoic acid, vanillic acid, and caffeic acid significantly increased from day 18 during the fermentation. Additionally, DPPH, ABTS radical scavenging activity, total phenol, and total flavonoid were confirmed to be increased until 18 days. NO was significantly inhibited from day 6, along with significant inhibition of iNOS, COX-2, and TNF-a. In conclusion, this study confirmed that CF of low-use (or underutilized) wild vegetables enhances phenolic compounds. It effectively suppresses NO, iNOS, COX-2, and TNF-𝛼, markers of inflammation-related pathogenesis. Altogether, our results suggest that CF of the above plants has a potential anti-inflammatory effect.

The aim of this study was to evaluate the potential of fermented red ginseng extract (FRGE) as feed additive in broilers and laying hens. In broilers, 480 Arbor Acre male broilers were randomly allotted to 4 treatments with 6 replications per treatment and 20 chicks per pen. The experiment lasted 5 weeks and dietary treatments were as follows: i) CON, basal diet; ii) FRGE1, basal diet+1 g/kg fermented red ginseng extract; iii) FRGE2, basal diet+2 g/kg fermented red ginseng extract and iv) FRGE3 basal diet+4 g/kg fermented red ginseng extract. Throughout the experiment, no effects were observed (p>0.05) in performance in response to FRGE. At the end of the experiment, FRGE administration improved (p<0.05) the lymphocyte level compared with CON. The relative weight of bursa of fabricius and spleen were increased (p<0.05) by the inclusion of FRGE3. Besides, redness ($a^*$) value for the breast meat was higher (p<0.05) in FRGE1 and FRGE3 treatments than that in CON. In laying hens, 240 ISA brown layers at 35 weeks of age were used in this 8-week trial. Dietary treatments were the same as in the broilers trial with 10 replicates per treatment and 6 layers per replicate. During the entire experiment, there were no significant differences (p>0.05) in performance or egg quality among all the treatments. However, the layers fed diets supplemented with FRGE had higher lymphocyte level (p<0.05) compared with those fed CON. In conclusion, the dietary supplementation with FRGE did not influence performance but improved the lymphocyte level in both broilers and laying hens.
