  • The growth responses of a variety of human intestinal bacteria to extracts of Panax ginseng and five other oriental medicinal Araliaceae were elraluattd in vitro and in vivo. The extracts enhanced the growth of Brifidobnnerilrm breve and B. longlim in media with or without carbon sources, suggesting that bifidus factors) might be involved in the phenomenon. This effect was most pronounced with water extract of P. ginseng, the growth of 27 bifidobacteria strains belonging to B adolescentis, B. longum, B. brim and B. infantis being greatly stimurated, whereas seven B. bifidum strains and other bacteria such as clostridia and Escherichin soli had little or no ability to utilise it for growth. Methanol extracts of p. ginseng were found to selectively inhibit growth of various clostridia including bifidobacteria. Paraputrificum, but this effect was not observed on other bacteria including bifidobacteria. The effect of ginseng extract intake (600 mg/day for two weeks) on the faecal microflora, pH, volatile fatty acids, ammonia, putrefactive products, and -glucuronidase, -glucosidase and nitroreductase activities, and on the blood components (triglyceride, total cholesterol and ammonia) were investigated using seven healthy human volunteers. The total concentration of faecal microflora including Bifidnkaderiifm app. during the period of ginseng extract intake %twas significantly unaffected from the preceding and subsequent control peroids. However, the frequency of occurrence of subjects having C. perfringens was significantly decreased. The faecal pH value was also significantly decreased, suggesting that the intake might increase the activity of Bifidobncterium spry. Other biochemical properties in faeces did not changed significantly. The levels of ammonia and triglycerid in blood were decreased with ginseng extract intake. These results may be an indication of at least one of the Pharmacological actions of p. ginseng as an adaptogen.

  • The growth responses of a variety of human Intestinal bacteria to extracts of Pun(1.vKy'n.ieny and five other oriental medicinal Araliaceae were evaluated in vitro and in vivo. The extracts enhanced the growth of Bifidobncterilim breve and B. longum in Media with or without carbon sources, suggesting the bifid factor (5) might be involved in the phenomenon. This effect was most pronounced with water extract of p. ginseng, the growth of 27 bifidobacteria strains belonging to B. ndolexcentium, H. longlrm, and 1. breve and B. iniuntis being greatly stimurated, whereas seven B. bifidum strains and other bacteria such as clostridia and 5.fcherirhia coli had little or no ability to utilizes it (or growth. Methanol extracts of p, ginseng were found to selectively inhibit growth of various clostridia including C. perfringens and C. Paraputrificum, but this effect was not observed on other bacteria including bifidobacteria. The effect of ginseng extract intake(600 mg/day for two weeks) on the fecal microflora, pH, volatile fatty acids, ammonia, putrefactive products, and -glucuronidase, -glucosidase and nitroreductase activities, and on the blood components (triglyceride, total cholesterol and ammonia) were investigated using seven healthy human volunteers. The total concentration of fecal microflora including Bri'idobucterilim app. during the period of ginseng extract intake was significantly unaffected from the proceeding and sub sequent control periods. However, the frequency of occurrence of subjects having C. perfringens was significantly decreased. The fecal pH value was also significantly decreased, suggesting that the intake might increase the activity of Bifidobacterium spp. Other biochemical properties in faces did not changed significantly. The levels of ammonia and triglycerid in blood were decreased with ginseng extract intake. These results may be an indication of at least one of the pharmacological actions of P ginseng as an adaptogen.

  • Bacteroides fragiles Roid8은 인간의 장내에서 가장 우세한 균종에 속하는 것으로서 효소활성을 측정해본 결과 다른 균들에 비해 $\alpha-fucosidase$의 활성이 높은 것으로 나타났다. 본 연구실에서 조사된 $\alpha-fucosidase$의 생산 최적배지 조성은 1L 배지당 BHI 37g, hemin 10mg, cysteine 0.5g, resazurin 1mg, vitamin K 1mg, starch 5g을 함유하였다. 또한 DEAE-sepharose와 CM-cellulose 크로마토그래피를 거쳐 조효소액을 분리하여 조사한 결과 효소의 최적 반응온도는 $40^{\circ}C$, 최적반응 pH는 7.0이었다. 무기 금속이온의 영향은 $Co^{++}\;and\;Zn^{++}$ 존재 하에서 효소역가가 낮아졌다.
