We have concerned the action of traditional herbal medicine (THM) to relate with longevity, aging and immune, etc. Espically, we have studied on the role of intestinal bacteria on THM such as Nokyongdaebo-Tang, Bojungikgi-Tang, Ikgibohyul-Tang, Bobyulansin-Tang and Bojanggunbi-Tang. Samples of the p.o. administration of 2 g/kg for 2 weeks did not find the change transaminase activities in mice. But, Nokyongdaebo-Tang and Bojanggunbi-Tang elevated the serum glucose levels and Bojungikgi-Tang elevated the total cholesterol levels in mice. ${\beta}-Glucuronidase$ activities in mice faeces are decreased by the treatment of Nokyongdaebo-Tang, Bojungikgi-Tang, Ikgibohyul-Tang and Bojanggunbi-Tang, but increased by the treatment of Bohyulansin-Tang. Number of lactic acid bacteria in mice faeces are increased by the treatment of Nokyongdaebo-Tang, Bojungikgi-Tang, lkgibohyul-Tang, Bohyulansin-Tang and Bojanggunbi-Tang. We recognized that ${\beta}-glucuronidase$ activities and the number of lactic acid bacteria were remarkably decreased by the pretreatment of antibiotics in mice. Nokyongdaebo-Tang and Ikgibohyul-Tang at the p.o. administration of 2 g/kg significantly increased the ${\beta}-glucuronidase$ activities and Bojungikgi-Tang and Bohyulansin-Tang remarkably increased the number of lactic acid bacteria in antibiotics pretreated mice.

Background : To investigate the effect of Hwanggeumjackyak-tang (HJT) on Dextran sulfate sodium (DSS) induced ulcerative colitis. Methods : The experimental animals were divided into three groups; group 1, normal group(Normal); group 2, DSS-induced colitis and untreated group(UT+DSS); group 3, DSS-induced colitis and HJT 200 mg-treated group(HJT200+DSS). We evaluated cytotoxicity after HJT administration and confirmed the anti-inflammatory effect by histological changes in the intestine and genetic analysis of mucosal cells after HJT administration for each group. In addition, microbiological weapons and metabolites in faeces were examined, and the correlation between gut microbiome and metabolites was also investigated. Result : HJT was not observed to be cytotoxic, even at relatively high concentrations, and was effective in protecting the barrier and preventing intestinal inflammation by suppressing the increase in mucus secretion and the expression of inflammatory factors in mucosal cells. HJT treatment affected the increase in the amount and diversity of the gut microbiome in faeces and the increase in metabolites thought to be involved in alleviating inflammation in the gut. Conclusion : This study demonstrates the therapeutic potential of HJT in ulcerative colitis. Further studies should be carried out to confirm our findings.

Application of water-saving self-feeders can reduce water consumption of pigs by more than 50% . so the feeding-watering system one of the most important way of the reduction of the slurry. Bioactive deep litter housing can eliminate slurry. Matured urine, faeces and litter can use for the purposes of soil conditioning and fertilizing . Water-saving slurry handling technology can halve manure dilution so it can double the nutrient content of the slurry. By using of straw bale biofilter for reducing emissions of pig houses makes fattening of pigs possible close to populated area. Developed rate control system for slurry application make avoiding over-fertilization possible , can fulfill better the demand of nutrient of plants. By means of computer aided manure utilization system area distribution of soil characteristics can determinate . The system is suitable for planning the utilization of manure and slurry in environment -friendly way.

A balance study was conducted to determine the requirements of iron, copper, cobalt and manganese in crossbred calves. Six calves were fed milk average 10 percent of their body weight and were supplemented with 15 g mineral mixture daily. A balance trial was conducted at $2\frac{1}{2}$ months of age. The primary route of excretion was through digestive tract as 99.87, 80.99, 77.27 and 99.94 percent of Fe, Cu, Co and Mn were excreted through faeces. The requirements of Fe, Cu, Co and Mn were computed using the respective mineral balance data and were found to be 169.60, 7.20, 4.48 and 8.89 mg/kg respectively.

Eighteen strains of Clostpidium perfringens were isolated from the piglets with hemorrhagic enteritis. The characteristics of the outbreaks, clinical signs and lesions were examined. The biochemical properties, type of toxins and susceptibility to antimicrobial agents against the isolates were investigated. 1. The incidence of diarrhea was appeared in 97(22.4%) of 432 piglets examined. 2. The isolation rate of Cl perfingens from the 97 diarrheal faeces were 18.5%(18 strains) 3. The population of Cl perfingens in feces were ranged $10^{8-9}$cfu/g in 5(32.5%) and $10^{3-7}$cfu/g in 13(67.4%) of 18 samples. 4. The toxin type of the 18 isolates investigated by mouse inoculation test was all type C strains of Cl perfringens. 5. As a results of antimicrobial susceptibility test, 18 isolates were higly susceptible to cephalothin, tetracycline and penicillin.

The aqueous and methanolic extracts of 110 crude drugs were screened for hyaluronidase inhibitory activity using a microplate assay. Among them, MeOH extract of 15 crude drugs inhibited more than 80% of hyauluronidase activity at the concentration of 5mg/ml. The active principles of Anemarrhenae Rhizoma, Rhei Rhizoma, Ephedrae Herba, Pteropi Faeces and Ginseng Radix alba were transferred into organic solvents.

본 연구는 성장중인 닭에 있어서 맹장내 혐기성 미생물수와 맹장의 길이와의 관계를 구명하기 위해서 실시되었다. 5주령의 160수의 닭을 80수씩 분리하여 케이지내 사육 (대조구)및 염소 방목장내 염소와 같이 사육 (처리구)의 2처리로 구분하여 실시하였으며, 본 시험기간동안의 사료는 닭의 성장단계에 적합한 시판의 사료를 기초사료로 활용하였다. 시험기간 (5∼8주형)까지의 증체량은 8주령 에서는 대조구가 처리구보다 유의하게 놀았으며(P<0.05), 12주령에서는 처리구가 대조구보다도 유의하게 높았다(p<0.05). 맹장의 길이는 6, 9, 10 및 11주령에 처리구가 대조구보다 유의하게 길었다 (P<0.05). 맹장내 총 혐기성미생물수도 6, 9, 10 빛 11주령에 처리구가 대조구보다 유의하게 많았다(P<0.05). 대조구 및 처리구 함께 맹장의 길이와 증체량간에는 r= 0.816의 상관관계가 인정되었다. 맹장의 길이와 맹장내 혐기성 미생물 수는 대조구 및 처리구 함께 r=0.95이상의 높은 상관 관계가 인정되었다(P<0.01). 결론적으로 성장중인 닭에 있어서 섬유소 함량이 높은 염소의 배설물 섭취 등의 영향에 따른 맹장내 혐기성 미생물 수의 증가가 맹장의 길이 증가에 관계되어진다.

This study was conducted to investigate lactobacillus salivarius subsp. salivarius having probiotic properties to be used as the health adjuncts with fermented milk products. Acid- and bile-tolerant lactobacillus salivarius subsp. salivarius was isolated with lactobacilli MRS broth from faeces of 80 healthy persons (infants, children and adults). It was used as a probiotic strain in fermented milk products. The pH of fermented milk decreased from pH 6.7 to 5.0 and titratable acidity increased from 0.3% to 1.0% by L. salivarius subsp. salivarius (isolation strain 20, 35, and 37), when incubated for 36 h at 37$^{\circ}C$. The number of viable cell counts of fermented milk was maximized at this incubation condition. The SDS-PAGE evidenced no significant change of casein but distinct changes of whey protein were observed by isolated L. salivarius subsp. salivarius for titratable acidity being incubated by 0.9-1.0% at 37$^{\circ}C$. All of the strains produced 83.43 to 131.96 mM of lactic acid and 5.39 to 26.85 mM of isobutyric acid in fermented products. The in vitro culture experiment was performed to evaluate ability to reduce cholesterol levels and antimicrobial activity in the growth medium. The selected L. salivarius subsp. salivarius reduced 23-38% of cholesterol content in lactobacilli MRS broth during bacterial growth for 24 h at 37$^{\circ}C$. All of the isolated L. salivarius subsp. salivarius had an excellent antibacterial activity with 15-25 mm of inhibition zone to E. coli KCTC1039, S. enteritidis KCCM3313, S. typhimurium M-15, and S. typhimurium KCCM40253 when its pH had not been adjusted. Also, all of the isolated L. salivarius subsp. salivarius had partial inhibition zone to E. coli KCTC1039, E. coli KCTC0115 and S. enteritidis KCCM3313 when it had been adjusted to pH 5.7. The selected strains were determined to have resistances of twelve antibiotic. Strains 27 and 35 among the L. salivarius subsp. salivarius showed the highest resistance to the antibiotics. These results indicated that some of the L. salivarius subsp. salivarius (strain 27 and 35) are considered as effective probiotic strains with a potential for industrial applications, but the further study is needed to establish their use as probiotics in vivo.
