The current study was designed to define whether a blend of prunus mume extract(25%) containing lactic acid(75%) and grape seed extract(10ppm) could affect in vitro antimicrobial activity and growth performance, intestinal microflora, plasma biochemical profiles and digestive enzymes activities in broiler chickens. In paper disc agar diffusion test, we clearly observed antimicrobial activity against E. coli in response to prunus mume extract or a blend of prunus mume extract. For in vivo test, a total of ninety six 3-d-old male broiler chicks were assigned to basal diet(CON), basal diet supplemented with antibiotics (ANTI) and 0.5% a blend of prunus mume extract(PRNUS) until 35 days of age. Throughout the entire experimental period(3-35 days), there were no differences in BW and FCR between the birds fed the basal diet with antibiotics and the diet supplemented with a blend of prunus mume. However, ANTI group showed a significant increase in BW and total gain compared to CON group. The weights of digestive organs such as the pancreas and mucosal tissues were not affected by dietary treatments. There was no difference in plasma levels of glucose, cholesterol, AST and ALT activity. However, triglyceride in plasma increased(P<0.05) in the birds fed the diet supplemented with 0.5% a blend of prunus mume extract compared to those fed antibiotics supplemented diet. The activities of pancreatic trypsin and amylase, and intestinal hydrolase including disaccharidase were not affected by dietary treatment. The colony forming units(CFU) of lactobacillus in the lower ileal-cecum of the birds fed the diet supplemented with a blend of prunus mume extract was significantly(P<0.05) higher than that of birds fed antibiotic supplemented diet without affecting the CFU of E. coli. In conclusion, the birds fed the diet supplemented a blend of prunus mume as an alternative to antibiotics showed a similar growth performance and an significant increase in lactobacillus population compared with the birds fed basal and antibiotics supplemented diets.

Phytoestrogens, especially soy-derived isoflavones, are receiving great scrutiny as a food supplement for preventing hormone dependent disease such as postmenopausal osteoporosis. Their beneficial effects are derived from aglycone form of isoflavones, such as daidzein, genistein or glycitein. In contrast to the common usage of soybean, black bean (Rhynchosia Molubilis : Yak-kong) has been used as a supplement for preventing postmenopausal osteoporosis in oriental medicine. To investigate the effects of the saliva, artificial stomach fluid, and digestive enzymes on the conversion of glycosidic isoflavone to aglycone form, soybean and black bean were extracted with 70% methanol and freeze-dried. The recovery yield of methanol extracts of black bean was 14.1% which was higher than that of soybean, 13.5%. In terms of total isoflavones, we routinely obtained larger amount of isoflavones from black bean than those from soybean. By incubating methanol extracts of soybean and black bean with IN HCI for 180 min, the proportions of aglycones relative to the total isoflavone were significantly increased (32.4% and 52.4%, respectively). In vitro conversion, digestive enzymes ($\beta$-glucosidase and $\alpha$-glucosidase) may hydrolyze glycosidic bond of isoflavone more effectively than saliva or artificial stomach fluid did. It seems to say that the activity of $\beta$-glucosidase was higher than those of $\alpha$-glucosidase. The rate of conversion of glucoside form to aglycone form in black bean and soybean was low in physiological condition (pH) tested, although the enzymatic hydrolysis of glucoside was active. These results demonstrated that the composition of aglycone in food may be the important factors in terms of the bioavailability of isoflavones. (Korean J Nutrition 36(1): 32-39, 2003)

Background and Objective: There has been no universally agreed standard chemotherapy regimen for patients with advanced biliary tract carcinomas (BTC). We aimed to fully display and evaluate the clinical evidence for gemcitabine or gemcitabine-cisplatin combination for advanced BTC. Methods: Systematic searches were performed to identify relevant randomized controlled trials (RCTs) and uncontrolled trials. Overall survival (OS), progression-free survival (PFS), overall response rates (ORR), tumor control rates (TCR), and toxicity were evaluated. Evidence levels of the results were evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Results of the eleven gemcitabine-cisplatin trials and ten gemcitabine trials showed both chemotherapy regimens had benefits with reference to mean OS (8.63 vs. 8.79 months), mean PFS (4.86 vs. 4.72 months), pooled ORR (25.3% vs. 19.6%) and TCR (55.2% vs. 53.1%). Two RCTs showed the gemcitabine-cisplatin combination to prolong the mean PFS (mean difference [MD] 2.57, 95%CI 1.69 3.45), substantially increasing the mean OS (MD 3.59, 95% CI 3.48 3.71), and producing a similar effect in ORR (risk ratio [RR] 1.59, 95%CI 1.04 2.43), increasing TCR (RR 1.15, 95%CI 1.02 1.31) compared with gemcitabine alone, with generally manageable grade 3 or 4 adverse events. The evidence level of OS was moderate, and other outcomes (ORR, PFS, TCR, anaemia, neutropenia) were at low evidence levels. Conclusion: Available evidence was limited with low quality, which showed that both gemcitabine-cisplatin and gemcitabine alone had clinical activity with acceptable safety profiles, and gemcitabine-cisplatin appeared to be more useful for advanced BTC patients than gemcitabine alone.

Objective: This study aimed to investigate the effect of Salvia miltiorrhiza (S.m.) aerial parts as an alternative ingredient on growth performance, nutrient digestibility, and digestive enzymes in growing rabbits. Methods: Treatments included five tested diets: a control (basal diet), antibiotic (basal diet+enramycin at 5 mg/kg), and S.m. aerial parts powder added at 3.0%, 6.0%, and 9.0% of feed using 300 growing rabbits. Results: The diets with S.m. aerial parts addition at 9.0% decreased (p<0.05) feed/gain compared to the control, but there were no differences in feed intake and body weight gain. In contrast with the control, the addition of antibiotic increased (p<0.05) digestibility of dry matter, crude protein, energy, fiber, and ash. The herb addition did not cause differences in the digestibility of most nutrients compared to the antibiotic, but fiber digestibility of the herb at 6.0% and 9.0% was lower (p<0.05) than that of the antibiotic. Moreover, the antibiotic and the herb also similarly increased (p<0.05) the activities of duodenal α-amylase, maltase, lipase, and trypsin, compared to the control, and the herb at 6.0% and 9.0% showed a greater (p<0.05) activity of elastase than the dose 3.0%. Conclusion: The obtained data indicate that S.m. aerial parts can be a potential forage in rabbit's diet at 9.0% with a beneficial regulation on nutrition and digestion.

This study was undertaken to investigate the proteolytic enzyme from Neungee mushroom [Sarcodon aspratus (Berk) S. Ito]. The proteolytic activity of Neungee was higher than other several edible mushrooms under various pHs. The potency of proteolytic enzyme of Neungee was same as the digestive drugs containing protease. So the proteolytic activity of the enzyme was increased in neutral or weak alkaline pH, whose characteristics would be alkaline protease. The specific activity of the purified enzyme obtained by using Tris acryl CM-cellulose ion exchange increased 20 times as compared with that of the crude extract. The proteolytic enzyme was stable at room temperature, but decomposition was fast when incubated at higher temperature more than $40^{\circ}C$. The half life of the enzyme was longest in neutral pH and rate constant was increased in acidic or alkaline solution.

This study was conducted to determine if dietary fiber would reduce exposure of the tissues to dietary benzo[a]pyrene(BP) , a well-known carcinogenic polycyclic aromatic hydrocarbon, as evaluated by benzo[a]pyrene hydroxylase (BPH) activity. The effects of three different sources of dietary fiber(pectin, polydextrose, and clellulose) on BPH activity were studied using Sprague-Dawley rats. In this study, male rats were fed a fiber-free purified diet for 7 days, whereupon they were switched to experimentla diets for 48h. After 48h, their liver, stomach , small intestinal mucosa and large intestinal mucosa were assayed for BPH activity. Thissues exposed to benzo[a]pyrene(400mg/kg diet, fiber-free) showed significant increse in the activity of BPH ; 27 times in liver, 7 times in stomach, 18 times in small intestinal mucosa and 3 times in large intestine. The inhibition in BP -induced BPH activity by dietary fiber in liver, stomach and small intestinal mucosa was observed in the decreasing order : 10 % perctin > 10% polydextrose >5 % polydextrose > 10% cellulose. Decreased BPH induction indicates that soluble dietry fibers, especially pectin and polydextrose in this study, protect the tissues of digestive system from exposure to BP.

The Present experiment was designed to investigate the effects of Soo Jeom San on the function of heart and digestive organs. And thus it was analyzed the total acidity, recovery effect, and the other various enzyme activities such as ATPase, Creatine kinase, Aspartate transaminase, and Lactate dehydrogenase. The results were obtained as follows : 1. The Total acidity decreased after Soo JeomSan administration for 6 days, however the total acidity inoreased after the drug administration for 9 days, these phenomena demonstrate that Soo Jeom San acts as a dual factor. The mechanism of decreasing the total acidity was considered to the inhibition of ATPase activity used for HCI active transport from parietal cells. 2. Soo Jeom San recovered the islets of Langerhans which was disrupted by streptozotocin. The recovery mechanism was suggested that Soo Jeom San stimulates the ${\beta}-cell$ proliferation. 3. Soo Jeom San inhibited the enzyme activities such as Creatine kinase and Aspartate transaminase, however the drug activated Lactate dehydrogenase. According to the obtained results, Soo Jeom San may be used for curing gastric ulcer and myocardiac infarction.
