Ginsenoside Rgl (Rgl), the pharmacologically active constituent of ginseng (Panax ginseng C.A. Meyer), has a variety of biological activities. The present study was undertaken to evaluate a possibility of Rgl whether it can be used in treatment or prevention of stress disorders. Animals were stressed by immobilization for 2 hours or electroshocks for 20 minutes. The normal group was not exposed to any stress. Rgl was subcutaneously injected as dosages of 5 and 10 mg/kg and red ginseng (RG) was orally administered 200 mg/kg as the positive control. Animals were given supplements for 5 days without stress, and then were given supplements for 5 days with stress. We recorded stress-related behavioral changes of experimental animals using the Etho-vision system. Weight of adrenal gland and levels of corticosterone in plasma were measured and stress related behaviors (smelling, grooming, face washing, rearing) were observed. Rgl didn't make significant behavioral changes in total open field and elevated plus maze test. Rgl did not influence on behavioral changes induced by electroshock stress. Whereas, 10 mg/kg of Rgl alleviated the increment of the freezing and face washing time and the decrement of the smelling and rearing time induced by restraint stress. The administration of Rgl 10 mg/kg has significantly increased the endurance time on rotating rod and swimming pool tests compared to the control group. These results indicate that Rgl can alleviate the damage induced by physical stress. This result suggests that Rgl may bea new candidate for treating stress related disorder.

LED 청색광과 적색광을 2년근 인삼에 대하여 혼합 처리하여 생육 반응과 진세노사이드 함량에 미치는 영향을 알아 본 결과 인삼의 지상부의 엽면적과 건물중은 청색광과 적색광의 비율이 1:1 처리에서 상대적으로 가장 높았으나 인삼 뿌리의 건물중은 1:3 비율이 가장 컸다. 진세노사이드 함량은 지상부은 청색광과 적색광 비율이 1:1에서 가장 높았지만 인삼 뿌리의 함량은 1:1 비율이 가장 낮았다.

Panax ginseng C. A. Meyer has been one of the most highly recognized medicinal herbs in the Orient. Previous experiments have demonstrated that $Rg_3,\;and\;Rg_5$ statistically significantly decreased the incidence of benzo(a)pyrene-induced mouse lung tumor, $Rh_2$ showed tendency of decrease and $Rh_1$ showed no effect. It was, therefore, concluded that $Rg_3,\;Rg_5\;and\;Rh_2$ are active cancer chemopreventive components in red ginseng and they either singularly or synergistically act in the prevention of cancer. This study was undertaken to compare the cancer chemopreventive effects of $Rg_3,\;Rg_5\;and\;Rh_2$(purity: more than $60\%$) isolated from fermented ginseng extract and BST fermented ginseng with fortified ginsenoside $Rg_3\;and\;Rh_2$. The cancer chemopreventive effects were investigated in experimental groups treated with benzo(a)pyrene(BP) with ginsenoside $Rg_3,\;Rg_5\;Rh_2\;or\;BST$ at three doses of $50^{\circ}C/ml,\;100^{\circ}C/ml\;and\;200^{\circ}C/ml$ When mice given with $50^{\circ}C/ml$ concentration of ginsenoside $Rg_3$ combined with BP for 6 weeks after BP administration, $Rg_3\;showed\;60\%$ of lung tumor incidence, where as $100^{\circ}C/ml\;and\;200^{\circ}C/ml\;of\;Rg_3$ combined with BP groups had significant decrease of incidence $(40.0\%)$ respectively, with the inhibition rate being $35.5\%.$ While the tumor incidence was not decreased in the group treated with BP and 50 of $Rg_5,$ the incidence was $34.0\%\;and\;32.0\%$ in the group treated with BP and 100 and 200 of $Rg_5$, respectively. These incidences were significantly less than the group treated with BP alone, with the inhibition rate being $45.2\%\;and\;48.4\%,$ respectively. On the other hand, in the group treated with BP and 50 of ginsenoside $Rh_2,$ the tumor incidence was not decreased. However, the incidence was $40.0\%\;and\;38.8\%$ in the experimental treated with BP and 100 and 200 of $Rh_2,$ respectively, with the inhibition rate being $45.2\%\;and\;48.4\%,$ respectively. In addition, the incidence showed the tendency to decrease in the experimental group treated with BP and 50 of BST which contained $16.2\%\;of\;Rh_2,\;15.4\%\;of\;Rg_3\;and\;2.5%\;of\;Rg_5.$ The tumor incidence was $54.0\%$ in this group. In the group treated with 100 and 200 of EST, the incidence was $34.0\%\;and\;30.0\%,$ respectively, the incidences significantly being lower than the group treated with BP alone, with the inhibiting rate being $45.2\%\;and\;51.6\%,$ respectively. The results of this study strongly suggested that ginsenoside $Rg_3,\;Rg_5\;and\;Rh_2$ are the active components of red ginseng having a cancer chemopreventive activity and $Rg_5$ is the strongest cancer chempopreventive among them. On the other hand, the results demonstrating that the incidence of lung tumor was more markedly reduced by BST fermented ginseng with fortified ginsenoside $Rh_2\;or\;Rg_3$ compared to the single component alone, suggest that the combination of these components may remarkablely improve the cancer preventive effect

The effect of different phytogenic feed additives on reducing odorous compounds in swine was investigated using in vitro fermentation and analyzed their microbial communities. Soybean meal (1%) added with 0.1% different phytogenic feed additives (FA) were in vitro fermented using swine fecal slurries and anaerobically incubated for 12 and 24 h. The phytogenic FAs used were red ginseng barn powder (Panax ginseng C. A. Meyer, FA1), persimmon leaf powder (Diospyros virginiana L., FA2), ginkgo leaf powder (Ginkgo biloba L., FA3), and oregano lippia seed oil extract (Lippia graveolens Kunth, OL, FA4). Total gas production, pH, ammonianitrogen ($NH_3$-N), hydrogen sulfide ($H_2S$), nitrite-nitrogen ($NO_2{^-}$-N), nitrate-nitrogen ($NO_3{^-}$-N), sulfate (${SO_4}^{--}$), volatile fatty acids (VFA) and other metabolites concentration were determined. Microbial communities were also analyzed using 16S rRNA DGGE. Results showed that the pH values on all treatments increased as incubation time became longer except for FA4 where it decreased. Moreover, FA4 incubated for 12 and 24 h was not detected in $NH_3$-N and $H_2S$. Addition of FAs decreased (p<0.05) propionate production but increased (p<0.05) the total VFA production. Ten 16S rRNA DGGE bands were identified which ranged from 96 to 100% identity which were mostly isolated from the intestine. Similarity index showed three clearly different clusters: I (FA2 and FA3), II (Con and FA1), and III (FA4). Dominant bands which were identified closest to Eubacterium limosum (ATCC 8486T), Uncultured bacterium clone PF6641 and Streptococcus lutetiensis (CIP 106849T) were present only in the FA4 treatment group and were not found in other groups. FA4 had a different bacterial diversity compared to control and other treatments and thus explains having lowest odorous compounds. Addition of FA4 to an enriched protein feed source for growing swine may effectively reduce odorous compounds which are typically associated with swine production.
