The purpose of this study is to investigate whether the intracellular hydrogen peroxide productions of mouse macrophage RAW 264.7 are modulated by Red Ginseng-Ejung-tang water extract (ER) and White Ginseng-Ejung-tang water extract (EG). Red Ginseng-Ejung-tang were composed of Red Ginseng, Atractylodes rhizome white, Zingiberis Rhizoma Siccus, and Glycyrrhizae Radix. White Ginseng-Ejung-tang were composed of White Ginseng, Atractylodes rhizome white, Zingiberis Rhizoma Siccus, and Glycyrrhizae Radix. The intracellular hydrogen peroxide productions were measured by dihydrorhodamine 123 assay with spectrofluorometer (excitation 485 nm; emission 535 nm). For 4, 20, 24, 44, 48, 68, and 72 h incubation, ER significantly increased hydrogen peroxide productions of RAW 264.7 at the concentration of 25, 50, 100, and $200{\mu}g/mL$ (P <0.05). EG for 4, 20, 24, 44, and 48 h incubation significantly increased hydrogen peroxide productions of RAW 264.7 at the concentration of 25, 50, 100, and $200{\mu}g/mL$ (P <0.05). For 68 and 72 h incubation, EG at the concentration of 50, 100, and $200{\mu}g/mL$ significantly increased hydrogen peroxide productions in RAW 264.7 (P <0.05). These results suggest that ER and EG have the immune-enhancing properties related with their increasing effects on the intracellular hydrogen peroxide production of macrophage.

This study was conducted to develop a healthy and functional drink using red ginseng, maekmoondong and omija using Saengmaeksan. Since the red ginseng extract was used as a raw material, it was diluted from 1,000 to 1,500 times using distilled water and the highest sensory score was obtained when the red ginseng extract was diluted to 1,500 times. When the red ginseng extract was mired with omija and maekmoondong, there was no difference between the ratio of 1: 20 : 1, 1 : 21 : 1 and 1: 22: 1 (red ginseng : omija : maekmoondong). In case of sweetener, honey showed the highest sensory store compared to sucrose, pear extract apple extract, sucralose and aspartame. Additionally, the sweetness was evaluated using all sweeteners and 10 brix or 11 brix showed the highest sensory score. Therefore, red ginseng extract was first mixed with omija and maekmoondong in the ratio of 1 : 20 : 1, and distilled water was added to 1,500 times of the amount of red ginseng extract. Honey was finally added to the mixture to obtain 10 brix concentration and this was highly acceptable.
