  • As the growth factor of lactic acid bacteria, LD (trehalose) was isolated from Lentinus edode5 by using silica gel column chromatography. LD induced the growth of Bifidobacteria breve and Lactobacillus brevis, which were isolated from human feces. LD selectively induced the growth of lactic acid bacteria among total microflora. When total intestinal microflora were cultured in the medium containing LD, it stimulated the growth of lactic acid bacteria and inhibited harmful enzymes, ${\beta}$-glucosidase, ${\beta}$-glucuronidase, and tryptophanase, of intestinal bacteria. LM, which was a monosaccharide from L. edooles, induced the growth of lactic acid bacteria but it seems to be invaluable in vivo. LH isolated from L. edodes by Sephadex G-100 column chromatography was not effective for the growth of lactic acid bacteria.

  • In this Study, we have attempted to determine the effects of dietary fructose polymers (fructan), high molecular-weight ${\beta}-(2,6)-linked$ levan, and low-molecular-weight ${\beta}-(2,1)-linked$ inulin, on two intestinal enzymes $({\beta}-glucuronidase\;and\;{\beta}-glucosidase)$. As a preliminary experiment, when intestinal microflora were cultured in anaerobic media harboring levan or its oligosaccharides, bacterial cell growth was observed in the levanoligosaccharide-supplemented media, but not in the levan-supplemented media, indicating that levan's size is important for the utilization by intestinal bacteria of levan as an energy Source. In our animal study, the intake of a levan-rich diet was determined to significantly attenuate the activity of the harmful enzyme $({\beta}-glucuronidase$, but d id not affect the activity of ${\beta}-glucosidase$.

  • Lactic acid bacteria have been considered as the most beneficial probiotic organisms contributing to inhibition of harmful and putrefactive intestinal bacteria. Among them, Bifidobacterium spp. has been considered as one of the most beneficial probiotic organism that can improve the health of humans, since it is one of the major bacteria flora in human intestine. However, the harmful enzyme-inhibitory activity of lactic acid bacteria of Kimchi, which is a representative Korean fermented food has not been evaluated. (omitted)

  • A study was conducted to assess the nutritive value of two diets based on a low-energy variety of wheat, RAC C1 and their effects on intestinal mucosal structure and function in broiler chickens. The diets were fed with or without microbial enzyme supplement to male and female broiler chickens. The digesta viscosity was reduced (p<0.001) through supplementation with a microbial enzyme in male and female chicks. Enzyme supplementation also improved the dietary apparent metabolizable energy content (p<0.001) and had slight but non-significant positive effects on chick growth and feed conversion ratio. Intestinal mucosal structure and enzyme function were not affected by microbial enzyme supplement. Male chicks consumed more feeds (p<0.001), attained higher final body weight (p<0.001) and were more efficient at feed utilization (p<0.01) than the female chicks. Except for duodenal villus surface area and ileal protein content, intestinal mucosal structure and enzyme activities were similar between the two sexes and dietary treatment groups. The study showed an improvement in the nutritive value of the diets in the presence of the microbial enzyme supplement.

  • This study was conducted to investigate the effects of dietary supplementation with multiple enzymes composed of phytase plus carbohydrolases (ROVABIO$^{(R)}$ Max, RM) on growth performance, nutritional availability and intestinal viscosity in broiler chicks. A total of one thousand, one-day-old male broiler chicks were randomly allotted into treatment groups that received one of five experimental diets for 32 days. Each group consisted of 40 birds and all experiments included five replicates. The dietary treatments included PC (a positive control diet), NC1 (65 kcal/kg, 0.15% and 0.10% less ME, available phosphorus and calcium levels, respectively, than the PC diet), NC2 (85 kcal/kg, 0.20% and 0.10% less ME, available phosphorus and calcium levels, respectively, than the PC diet), NC1+RM (NC1 plus ROVABIO$^{(R)}$ Max) and NC2+RM (NC2 plus ROVABIO$^{(R)}$ Max). The average body weights, daily body weight gains and feed conversion rates of the chicks fed a diet containing RM improved significantly or tended to improve. The treatments also had no effect on the carcass characteristics or blood parameters, but the viscosity of the intestinal contents of the chicks fed the diet containing RM was significantly lower than that of chicks in the NC without RM groups. Additionally, chicks fed the dietary RM showed increased breaking strength and ash content of the tibia when compared to chicks that received the non-RM diets. Taken together, the results of the present study indicated that the addition of multiple enzymes consisting of phytase plus NSP enzymes improved the growth performance and mineral status of the tibia in broiler chickens fed corn-wheat-soybean meal-based diets with reduced levels of nutrients. Further, these findings suggest that the improved animal performance is associated with reduced intestinal viscosity by the dietary enzyme complex.

  • To investigate the intestinal absorption of a fibrinolytic and proteolytic lumbrokinase extracted from Eisenia andrei, we used rat everted gut sacs and an in situ closed-loop recirculation method. We extracted lumbrokinase from Eisenia andrei, and then raised polyclonal antibody against lumbrokinase. Fibrinolytic activity and proteolytic activity in the serosal side of rat everted gut sacs incubated with lumbrokinase showed dose- and time-dependent patterns. Immunological results obtained by western blotting serosal side solution using rat everted gut sacs method showed that lumbrokinase proteins between 33.6 and 54.7 kDa are absorbed mostly by the intestinal epithelium. Furthermore, MALDI- TOF mass spectrometric analysis of plasma fractions obtained by in situ recirculation method confirmed that lumbrokinase F1 is absorbed into blood. These results support the notion that lumbrokinase can be absorbed from mucosal lumen into blood by oral administration.

  • Schizandrae Fruits has been used as a traditional Oriental medicine for treatment of many stress-induced diseases. In the present study, we investigated inhibitory activity of enzymatic hydrolysate of Schizandrae fructus (SC-EX) in growth of tested intestinal microorganism and activity of bowel inflammation related enzyme. SC-EX was added to the proteose peptone-yeast extract-fildes (PYF) media to investigation the effect on the growth of type culture of intestinal microorganism. The growth of lactic acid bacteria such as Bifidobacterium species and Lactobacillus species was accelerated by more than 3% concentration of SC-EX. But, growth of harmfulness bacteria such as E.coli, Clostridium sp. Staphylococcus sp. Streptococcus sp. was inhibited by more than 3% concentration of SC-EX. Also, SC-EX was exhibited a concentration-dependent inhibitory activity of the bowel inflammation related enzymes. The SC-EX was showed 76% and 92% inhibitory activity of 5-lipoxygenase and cyclooygenase at 5% additional concentration respectively. Our results indicated that SC-EX may possess improvement effect on the intestinal flora and Anti-inflammatory effect on the bowel.

  • This paper attempts to investigate the effect of proteolytic enzyme on the absorption and excretion of pyrazinamide. The rat small intestinal absorption of pyrazinamide in the presence of proteolytic enzyme such as chymotrypsin and compounding enzyme (chymotrypsin and trypsin) are increasingly absorbed, but in the trypsin are similar to that of control. Blood levels of pyrazinamide after rabbit's duodenum injection are significantly enhenced to correspond to 112-120% by proteolytic enzymes concentration respectively, but both on the high concentration of chymotrypsin and the low concentration of trypsin are insignificantly enhenced. Proteolytic enzymes do not give the effect on clearance of pyrazinamide. Proteolytic enzymes give the effect on absorption of pyrazinamide, but do not give the effect on excretion of pyrazinamide.

  • Colon drug delivery is advantageous in the treatment of colonic disease and oral delivery of drugs unstable or suceptible to enzymatic degradation in upper GI tract. In this study, multilayer coated system that is resistant to gastric and small intestinal conditions but can be easily degraded by colonic bacterial enzymes was designed to achieve effective colon delivery of prednisolone. Variously coated tablets containing prednisolone were fabricated using chitosan and cellulose acetate phthalate (CAP) as coating materials. Release aspects of prednisolone in simulated gastrointestinal fluid and rat colonic extracts (CERM) were investigated. Also, colonic bacterial degradation study of chitosan was performed in CERM. From these results, a three layer (CAP/Chitosan/CAP) coated system exhibited gastric and small intestinal resistance to the release of prednisolone in vitro most effectively. The rapid increase of prednisolone in CERM was revealed as due to the degradation of the chitosan membrane by bacterial enzymes. The designed system could be used potentially used as a carrier for colon delivery of prednisolone by regulating drug release in stomach and the small intestine.
