  • Disease associated with microorganisms are far from resolved by current therapeutics. One of effective approach to health maintenance and disease control is the use of dietary bacterial and carbohydrate supplements. This comprises use of probiotics and prebiotics. Probiotics mean the live microorganisms, which when administered in adequate amounts confer a health benefit on the host. Prebiotics mean a nondigestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria that can Improve the host health. Especially, probiotics has the relation which is close with innate immunity and adaptive immunity. And probiotics has the clinical value with many disease like lactose intolerance, constipation, acute gastroenteritis, food hypersensitivity and allergy, atopic dermatitis, crohn's disease, rheumatoid arthritis, pelvic radiotherapy, intestinal inflammation and chemical exposure, colon cancer, inhibitory effect of Helicobacter pylori and lowering the level of cholesterol. We use jointly korean medicine and probiotics and it has the more therapeutic effect in the many disease.

  • Analysis of health-related microbes called probiotics was performed by capillary electrophoresis. A rapid and easy characterization for two important probiotics, Saccharomyces cerevisiae and Enterococcus feacalis, was obtained in the running buffer containing poly(ethylene oxide). Quantitation of probiotic (Saccharomyces cerevisiae) shows a good linearity between the peak area versus the concentration of microbe. From the comparison of electropherograms of antidiarrhea, it was found that capillary electrophoresis could be employed for the quality control and quality assurance for the production of a medicine containing the probiotics.

  • Objective: This study was conducted to evaluate the effect of probiotics (Bacillus subtilis and Enterococcus faecium) and xylo-oligosaccharide (XOS) supplementation on growth performance, nutrient digestibility, serum profiles, intestinal health, fecal microbiota and noxious gas emission in weanling pigs. Methods: A total of 240 weanling pigs ([Yorkshire${\times}$Landrace]${\times}$Duroc) with an average body weight (BW) of $6.3{\pm}0.15kg$ were used in this 28-day trial. Pigs were randomly allocated in 1 of the following 4 dietary treatments in a $2{\times}2$ factorial arrangement with 2 levels of probiotics (0 and 500 mg/kg probiotics) and XOS (0 and 200 mg/kg XOS) based on the BW and sex. Results: Administration of probiotics or XOS improved average daily gain (p<0.05) during 0 to 14 d and the overall period, while pigs that were treated with XOS had a greater average daily gain and feed efficiency (p<0.05) compared with unsupplemented treatments throughout 15 to 28 d and the whole experiment. Either probiotics or XOS treatments increased the apparent total tract digestibility of nutrients (p<0.05) during 0 to 14 d. No effects on serum profiles were observed among treatments. The XOS increased villus height: crypt depth ratio in jejunum (p<0.05). The supplementation of probiotics (500 mg/kg) or XOS (200 mg/kg) alone improved the apparent total tract digestibility of dry matter, nitrogen and gross energy on d 14, the activity of trypsin and decreased fecal NH3 concentration (p<0.05). Administration of XOS decreased fecal Escherichia coli counts (p<0.05), while increased lactobacilli (p<0.05) on d 14. There was no interaction between dietary supplementation of probiotics and XOS. Conclusion: Inclusion of XOS at 200 mg/kg or probiotics (Bacillus subtilis and Enterococcus faecium) at 500 mg/kg in diets containing no antibiotics significantly improved the growth performance of weanling pigs. Once XOS is supplemented, further providing of probiotics is not needed since it exerts little additional effects.

  • 본 실험은 육계에 서로 다른 혼합미생물을 급여하여 효과를 구명하고자 실행하였다. 1일령 로스 수컷 400수에 무첨가구인 대조구와 생균제 A와 B를 각각 0.1과 0.2%수준으로 5개처리구 5반복 반복당 16수씩 평사로 5주간 급여하였다. 증체량, 사료섭취량, 사료요구율을 주간별로 측정하였으며, 실험 종료시에 회장과 맹장의 전체 유산균, 효모균, 살모넬라, 대장균 수를 조사하였다. 혈장의 단백질, 콜레스테롤, ND 백신항체가를 측정하였고, 분에서 발생되는 $CO_2$, NH$_3$. COD를 측정하였다. 증체량은 사육 초기 3주간에 생균제 급여구에서 대조구보다 높은 경향이었으며, 후기 2주간에는 현저하게 높았다(P<0.05). 사료섭취량은 처리구간에 통계적인 차이가 없었으며, 사료요구율은 생균제 B 처리구에서 다른 처리구보다 유의적으로 개선되었다. 전체 살모넬라 수는 회장에서 일관성이 없었지만 대장균수는 생균제 급여구에서 대조구에 비하여 낮게 나타났다. 분에서 NH$_3$$CO_2$ 발생도 생균제 급여구에서 대조구에 비하여 낮았지만 통계적인 차이는 없었으며 계분의 COD는 다른 유해가스의 발생과 동일한 경향을 나타냈다. 혈중 전체 콜레스테롤은 생균제 종류에 관계없이 낮은 경향을 나타냈다. ND백신 항체가는 생균제 급여구에서 높아지는 경향을 나타냈다.

  • This study was conducted to investigate the effects of supplementation of a probiotics complex on growth performance, nutrient digestibility, diarrhea score and microbial population in pigs weaned at 21 days of age. Treatments were 1) control A (0.2% antibiotics, Avilamycin), 2) control B (0.1 % $Ractocom^{(R)}$), 3) 0.1%, 4) 0.2% and 5) 0.3% probiotics complex; 80 pigs were used and each treatment had 4 replicates with 4 pigs per replicate (16 pigs per treatment). During phase I period (d 0 to 14), although there was no significant difference, pigs fed control B diet showed higher ADG (average daily gain) and better F/G (feed/gain) than any other treatments. During late experimental period (d 15 to 28), pigs fed diet supplemented with 0.2% probiotics complex showed slightly higher ADG. Overall (d 0 to 28) the diet that contained 0.2% probiotics complex gave slightly higher ADG and ADFI (average daily feed intake) than the other diets. In a metabolic trial using 20 piglets, nutrient digestibility showed the best results in pigs fed 0.2% probiotics complex diet, but not significantly different from other groups. Diarrhea score and microbial population status in intestine, colon and feces were not affected by dietary treatments. In conclusion, this study suggested that a newly developed probiotics complex can replace antibiotics in weaned pigs.

  • It has been suggested that probiotics could be useful for the prevention of symptomatic relapse in patients with inflammatory bowel disease (IBD). Interleukin (IL)-8 has been well recognized as one of the pro-inflammatory cytokines that could trigger inflammation and epithelial barrier dysfunction. In this study, the anti-inflammatory effects of probiotics were investigated using a human epithelial cell line (HT-29). Probiotics from infant feces and kimchi were tested for their cytotoxicity and effects on adhesion to epithelial cells. The present results show that seven strains could form 70 % adhesion on HT-29. The probiotics used in this study did not affect HT-29 cell viability. To screen anti-inflammatory lactic acid bacteria, HT-29 cells were pretreated with live and heat-killed probiotics, and lipopolysaccharide (LPS) ($1{\mu}g/mL$) was then added to stimulate the cells. The cell culture supernatant was then used to measure IL-8 secretion by ELISA, and the cell pellet was used to determine IL-8 and toll-like receptor (TLR-4) mRNA expression levels by RT-PCR. Some probiotics (KJP421, KDK411, SRK414, E4191, KY21, and KY210) exhibited anti-inflammatory effects through the repression of IL-8 secretion from HT-29 cells. In particular, Lactobacillus salivarius E4191, originating from Egyptian infant feces, not only decreased IL-8 mRNA expression, but also decreased TLR-4 expression. These results indicate that Lactobacillus salivarius E4191 may have a protective effect in intestinal epithelial cells.

  • A complex interplay between genetic and environmental factors partially contributes to the development of allergic diseases by affecting development during prenatal and early life. To explain the dramatic increase in the prevalence of allergic diseases, the hygiene hypothesis proposed that early exposure to infection prevented allergic diseases. The hygiene hypothesis has changed to the microbial hypothesis, in which exposure to microbes is closely linked to the development of the early immune system and allergic diseases. The intestinal flora may contribute to allergic disease through its substantial effect on mucosal immunity. Based on findings that exposure to microbial flora early in life can change the Th1/Th2 balance, thus favoring a Th1 cell response, probiotics may be beneficial in preventing allergic diseases. However, evidence from clinical and basic research to prove the efficacy of probiotics in preventing allergy is lacking. To date, studies have yielded inconsistent findings on the usefulness of probiotics in allergic diseases. It is difficult to demonstrate an exact effect of probiotics on asthma, allergic rhinitis, and food allergy because of study limitations, such as different first supplementation period, duration, different strains, short follow-up period, and host factors. However, many studies have demonstrated a significant clinical improvement in atopic dermatitis with the use of probiotics. An accurate understanding of the development of human immunity, intestinal barrier function, intestinal microbiota, and systemic immunity is required to comprehend the effects of probiotics on allergic diseases.
