  • Purpose : This study was conducted to investigate the antimicrobial effects of herb for removing dampness and promoting urination against vaginal microbes. Methods : Staphylococcus aureus. Methicillin-resistant Staphylococcus aureus(MRSA), Candida albicans and Gardnerella vaginalis were used for vaginitis-induced microbes. Lactobacillus gasseri, Streptococcus spp. and Escherichia coil HB101 were used for normal vaginal florae. And herbs for removing dampness and promoting urination(Dianthi herbs. Tokoro Rhizoma, Saururi Herbs, Pyrrosiae Folium, Artemisiae Iwayomogii Herba, Plantaginis Semen, Tetrapanacis Medulla, Polygoni Avicularis Herba, Malvae Semen, Akebiae Caulis, Kochiae Fructus, Lygodii Spora) were used. Antimicrobial activities were estimated by the change of optical densities and colony test in vitro. Results : Plantaginis Semen, Artemisiae Iwayomogii Herba and Lygodii Spora had the antimicrobial susceptibility and selective toxicity against MRSA and Gardnerella vaginalis. Polygoni Avicularis Herba had the antimicrobial susceptibility and selective toxicity against Staphylococcus aureus. MRSA and Gardnerella vaginalis. Malvae Semen and Kochiae Fructus had the antimicrobial susceptibility and selective toxicity against MRSA. Dianthi Herba had the antimicrobial susceptibility and selective toxicity against Gardnerella vaginalis. Conclusion : According to these results, we can suggest that Plantaginis Semen, Artemisiae Iwayomogii Herba, Lygodii Spora, Polygoni Avicularis Herba, Malvae Semen, Kochiae Fructus and Dianthi Herba would be available to the antimicrobial agent for vaginitis-induced microbe in vitro.

  • Two experiments were conducted to evaluate the effects of a complex Lactobacilli preparation on performance, resistance to E. coli infection and gut microbial flora of weaning pigs. In exp. 1, twelve pigs (7.65$\pm$1.10 kg BW), weaned at 28 d, were randomly allotted into 2 groups and placed in individual metabolic cages. During the first 7 d, one group of pigs was provided ad libitum access to water containing $10^5$ colony forming units (CFU) Lactobacilli per ml and the control group was provided tap water. The Lactobacilli preparation included Lactobacillus gasseri, L. reuteri, L. acidophilus and L. fermentum, which were isolated from the gastrointestinal (GI) tract mucosa of weaning pigs. On d 8, 20 ml of $10^8$ CFU/ml E. coli solution (serovars K99, K88 and 987P at the ratio of 1:1:1) was orally administered to each pig. Diarrhea scores and diarrhea incidence were recorded from d 7 to 14. On d 14, pigs were euthanized and digesta and mucosa from the stomach, duodenum, jejunum, ileum, cecum and colon were sampled using aseptic technique to determine microflora by culturing bacteria in selective medium. The results showed that Lactobacilli treatment significantly decreased E. coli and aerobe counts (p<0.01) but increased Lactobacilli and anaerobe counts (p<0.01) in digesta and mucosa of most sections of the GI tract. A 66 and 69.1% decrease in diarrhea index and diarrhea incidence, respectively, was observed in the Lactobacilli treated group. In exp. 2, Thirty-six crossbred Duroc$\times$Landrace$\times$Yorkshire piglets, weaned at 28$\pm$2 days, were selected and randomly allocated into 2 groups. There were 18 piglets in each group, 3 piglets in one pen and 6 replicates in each treatment with 3 pens of barrow and 3 pens of female piglet in each treatment. Piglets had ad libitum access to feed and water. The initial body weight of piglet was 7.65$\pm$1.09 kg. Dietary treatments included a non-medicated basal diet with Lactobacilli ($10^5$ CFU/g diet) or carbadox (60 mg/kg) as control. On d 21, six pigs per group (one pig per pen) were euthanized. Ileal digesta was collected to determine apparent amino acid digestibility. Microflora content was determined similarly to exp.1. The results showed that Lactobacilli treatment significantly improved average daily feed intake (ADFI) of pigs compared to carbadox (p<0.05) during the first 2 wks after weaning and average daily gain (ADG) and ADFI increased significantly (p<0.05) from d 8 to 14. Nitrogen and total phosphorus digestibility also increased (p<0.05). Bacterial counts were similar to exp. 1. The results indicate that the complex Lactobacilli preparation improved performance for 2 wks after weaning, enhanced resistance to E. coli infection, and improved microbial balance in the GI tract.

  • Rice bran is byproducts of the hulling of rice, an important food resource in Korea. Various studies have been reported immune-enhancing effects of rice bran cultured with Lentinus edodes. In particular black rice bran contains anthocyanin, and the effects of antioxidant have been reported. The objective of the this study was to investigate the possible immune-enhancing effects of black rice bran substance extracted from a submerged culture of Lentinus edodes with black rice bran (crude fermentation-polysaccharide, CFP) and products(crude fermentation-polysaccharide-S. cerevisiae CFP-S, crude fermentation-polysaccharide-L. gasseri, CFP-L) which are of secondary fermentation of by using Saccharomyces cerevisiae and Lactobacillus gasseri in the Blab/c male mice. We found that supplementation of CFP, CFP-S and CFP-L enhanced macrophage and splenocyte proliferation compared to the control group(NC) in mice. Also, we measured the concentration of cytokines(IFN-${\gamma}$, TNF-${\alpha}$, IL-6) secreted by activated macrophage and splenocyte. The results of the experiment are that supplementation of CFP and CFP-S increased the macrophage and splenocyte proliferation compared to the control group but supplementation of CFP-L decreased the splenoyte proliferation compared to the control group(without mitogen and treated with LPS). When macrophage and splenocyte were stimulated by CFP and CFP-S supplementation, it was increased IFN-${\gamma}$, TNF-${\alpha}$ and IL-6 concentration compared with the control group. These results suggest that the capacity of CFP and CFP-S seem to act as a potent immune modulator causing augmentation of immune cell activity, and enhance the immue function through regulating cytokine production capacity by activated macrophage and splenocyte in mice.

  • The purpose of this study was to investigate changes in the contents of constituents in Sipjundaebo-tang (SJ) and its fermentations (FSJ) with 8 species of lactic acid bacteria. Eight strains of lactic acid bacteria, Lactobacillus casei KFRI129, L. plantarum KFRI 144, L. curvatus KFRI 166, L. hilgardii KFRI 229, L. delbruekil subsp. lactis KFRI 442, L. casei KFRI 692, L. gasseri KCTC 3163, and Bifidobacterium breve KFRI 744, were utilized for the fermentation of Sipjundaebo-tang. As a result we identified three constituents which increased and two constituents which decreased. The increased constituents were isolated by chromatographic techniques and then their structure elucidated using NMR and MS. The decreased constituents were confirmed by comparing standard compounds. These compounds were quantitatively analyzed using the HPLC/DAD system. The increased constituents were identified to be cinnamyl alcohol (1), liquiritigenin (3), and nodakenetin (5), while the decreased constituents were liquiritin (2) and nodakenin (4). Generally, liquiritin (2) and nodakenin (4) were noted as having decreased in fermented Sipjundaebo-tangs (FSJs), while cinnamyl alcohol (1), liquiritigenin (3), and nodakenetin (5) were seen to have increased. Sipjundaebo-tang fermented by L. plantarum KFRI144 exhibited the most remarkable changes in all of fermentations. The eight lactic acid bacteria all demonstrated differing decomposable rates on the five maker compounds in fermented Sipjundaebo-tang (FSJ).
