Purpose: The aim of this study was to evaluate the clinical significance of inflammatory biomarkers in acute infectious diarrhea among children. Methods: Clinical parameters including fever, bacterial and viral etiology based on stool culture and multiplex polymerase chain reaction, and nine biomarkers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leukocytes in blood and calprotectin, lactoferrin, myeloperoxidase, polymorphonuclear elastase, leukocytes, and occult blood in feces were evaluated in children who were hospitalized due to acute diarrhea without underlying disease. Results: A total of 62 patients were included. Among these patients, 33 had fever, 18 showed bacterial infections, and 40 patients were infected with 43 viruses. Of all the biomarkers, CRP was significantly correlated with fever (p<0.001). CRP, ESR, calprotectin, lactoferrin, myeloperoxidase, fecal leukocytes, and occult blood were significantly associated with infection with bacterial pathogens (p<0.001, p=0.04, p=0.03, p=0.003, p=0.02, p=0.03, p=0.002, respectively). The combination of CRP and fecal lactoferrin at their best cut-off values (13.7 mg/L and $22.8{\mu}g/mL$, respectively) yielded a sensitivity of 72.2%, and a specificity of 95.5% for bacterial etiology compared with their individual use. Conclusion: Blood CRP is a useful diagnostic marker for both fever and bacterial etiology in acute pediatric diarrhea. The combination of CRP and fecal lactoferrin yields better diagnostic capability for bacterial etiology than their use alone for acute diarrhea in children without underlying gastrointestinal disease.
Thirty two Holstein female calves (initial body weight = $40{\pm}3.0$ kg) were used to investigate the effects of probiotic and prebiotic on average daily gain (ADG), fecal E. coli count, white blood cell count, plasma IgG1 level and cell-mediated immune response to injection of phytohemagglutinin in suckling female calves. Calves were assigned randomly to one of the four treatments, including whole milk without additives (control), whole milk containing probiotic, whole milk containing prebiotic and whole milk containing probiotic and prebiotic (synbiotic). Average daily gain was greater in calves fed probiotic, prebiotic and synbiotic at weeks 6, 7 and 8 (p<0.05). E. coli count was significantly lower in calves fed probiotic, prebiotic and synbiotic on d 56 (p<0.05). There was no significant difference between treatments in blood samples and cell-mediated response. This study showed that addition of probiotic, prebiotic and combination of these additives to milk enhanced ADG and reduced fecal E. coli count in preruminant calves.

This study was conducted to identify the useful blood variables in diagnosing calf diarrhea in Hanwoo calves and good indicators for calf diarrhea. In 530 Hanwoo calves, fecal scores were recorded on a scale of 0 to 3, and blood samples were collected and analyzed for hematology, serum biochemistry, and acute phase proteins. Among the blood variables, 16 blood variables showed significant differences (p < 0.01) according to fecal scores. After reference intervals of these 16 blood variables were calculated, the distributions of calves by calculated reference intervals showed a significant difference (p < 0.001) and linear associations (p < 0.001) in blood urea nitrogen (BUN), glucose (GLU), blood sodium concentration (Na), blood potassium concentration (K), fibrinogen (Fib), and haptoglobin (Hp). Of 6 blood variables, the optimal cut-off values were calculated for BUN, K, Fib, and Hp, and the area under the curve was 0.5 or more: BUN (9.5 mg/dL, AUC: 0.623), K (5.8 mmol/L, AUC: 0.599), Fib (650.0 mg/dL, AUC: 0.706), and Hp (12.5 mg/dL, AUC: 0.847). These findings could be useful in evaluating calves with diarrhea and making decision of further treatment of calf diarrhea in Hanwoo calves.

This study was undertaken to determine the effects of dietary supplementation with herbal extracts of Portulaca oleracea L. (POL), on the reproductive performance, blood profiles, immune response, and fecal microbial population in multiparous sows. On the basis of initial body weight, a total of 20 multiparous sows (Landrace×Yorkshire; 229.2±1.15 kg) were randomly allotted to 2 treatment groups, each including 10 replicates. The dietary treatments were administered during the lactation period, and included a corn-soybean meal-based diet (control group) and diet supplemented with 0.05% POL. Throughout the experimental period, no significant differences were observed between the two diet groups for body weight, backfat thickness, and reproductive performance. Blood profile analysis revealed significantly decreased lymphocyte concentrations and IL-1β levels (p<0.05), and increased serum IgG levels (p=0.051), of sows consuming the POL supplemented diet. Furthermore, coliform counts tended to decrease in sows consuming diet supplemented with POL (p=0.063). Taken together, our results indicate that POL supplemented diets exert beneficial effects on blood profiles, immune response, and fecal microflora of multiparous sows, without any negative effect on the reproductive performance.
A 5-wk trial with 96 ($(Landrace{\times}Yorkshire){\times}Duroc$) pigs ($BW=26.56{\pm}0.42kg$) was conducted to investigate the effect of eugenol and cinnamaldehyde as feed additive in growing pigs. Pigs were assigned to 1 of 3 treatments in a randomized complete block design according to their sex and BW. Each treatment contained 8 replications with 4 pigs (2 gilts and 2 barrows) per pen. Treatments included: control (basal diet; CON); (basal diet+1,000 mg eugenol/kg; ET); (basal diet+1,000 mg cinnamaldehyde/kg; CT). Administration of eugenol and cinnamaldehyde did not did not affect (p>0.05) the growth performance and apparent total tract digestibility. Dietary CT and ET led to a higher (p<0.05) lymphocyte concentration compared with CON. The inclusion of CT and ET decreased (p<0.05) the fecal E. coli concentration (p>0.05). Pigs fed the diets supplemented with eugenol and cinnamaldehyde had reduced (p<0.05) $NH_3$ and $H_2S$ concentration throughout the experiment. In conclusion, results obtained in the present study indicated that supplementation of eugenol and cinamaldehyde had no effect on growth performance of pigs but exhibited lymphocyte-enhancing activity and decreased the fecal E. coli concentration and fecal noxious gas content ($NH_3$ and $H_2S$).
The present study was conducted to evaluate the usefulness of common Korean legumes as a high-fiber supplement in therapeutic diets for diabetic patients. Streptozotocin-induced diabetic rats were used as animal models and four kinds of legumes, black soybean (BS), yellow soybean (YS), green pea (GP) and soybean curd residue (SCR) were tested as high-fiber supplements. Seven groups of normal and streptozotocin-induced diabetic rats were fed isocaloric experimental diets containing 8% dietary fiber from one of four legumes or purified cellulose and pectin for 6 weeks. The effects of the legumes on the glucose and lipid metabolism of diabetic rats was examined and compared with the effects of cellulose and pectin. The legume supplementation did not show any beneficial effect on glucose tolerance, however, it exhibited a plasma cholesterol-lowering effect in diabetic rats. The cholesterol-lowering action was especially strong in BS and the degree of the effect was comparable to that of pectin. The levels of total lipids, cholesterol, and triglyceride in the hepatic tissues of rats fed legume diets were similar to those of the pectin group. All legume supplements induced an increase in fecal steroid excretion. The fecal cholesterol contents were significantly high following the supplementations of YS and SCR (p < 0.05). The excretion of fecal bile acids in the BS and YS groups was significantly higher than it was in the pectin group (p < 0.05). Concentration of lipid peroxidation products in the blood and urine of diabetic animals was lower in the legume groups than in the cellulose group. The levels of hepatic lipid peroxidation products were significantly lower in the BS and YS groups than in the pectin group (p < 0.05). From the results of this study, the plasma cholesterol-lowering effect of BS is possibly due to the significant (p < 0.05) in-crease in fecal steroid excretion, which suggests that BS could be beneficial in improving abnormal lipid metabolism in diabetic rats.

The safety assessment of Bifidobacterium longum SPM1205 isolated from healthy Koreans and this strain's inhibitory effects on fecal harmful enzymes of intestinal microflora were investigated. The overall safety of this strain was investigated during a feeding trial. Groups of SD rats were orally administered a test strain or commercial reference strain B. longum $1\times10^9\;CFU/kg$ body weight/day for four weeks. Throughout this time, their feed intake, water intake and live body weight were monitored. Fecal samples were periodically collected to test harmful enzyme activities of intestinal microflora. At the end of the four-week observation period, samples of blood, liver, spleen, kidney, and gut tissues were collected to determine for hematological parameters and histological differences. The results obtained in this experiment demonstrated that four weeks of consumption of this Bifidobacterium strain had no adverse effects on rat's general health status, blood biochemical parameters or histology. Therefore, it is likely to be safe for human use. Fecal harmful enzymes such as $\beta-glucosidase,\;\beta-glucuronidase$, tryptophanase and urease, were effectively inhibited during the administration of the B. longum SPM1205. These results suggested that this B. longum SPM 1205 could be used for humans as a probiotic strain.
This study was performed to investigate the effets of hesperidin extracted from tangerine peel on Cadmium (Cd) and lipid metabolism lipid peroxide formation, and antioxidative enzyme activities in rats. Forty-eight male Sprague-Dawley rats weighing 158.3$\pm$3.5g were blocked into eight groups according to body weight. Rats were raised for three weeks with diets containing 0 or 0.04%(w/w) cadmium chloride and 1%(w/w) extracted hesperidin from tangerine peel, commercial hesperidin or naringin. Food intake, weight gain and food efficiency ratio were significantly lower in the Cd-administered groups. The Cd concentrations in blood and liver and the Cd excretions in urine and feces were significantly higher in the Cd-administered groups. Among the Cd groups, blood Cd concentrations were decreased, fecal Cd excretions were increased, and Cd retenition ratios were decreased by feeding flavonoid diets. Plasma total lipid concentrations were significantly lower in the extracted hesperidin group, plasma triglyceride concentrations were significantly lower in the extracted hesperidin and naringin groups. Plasma HDL-cholesterol concentrations and HDL : total cholesterol ratios were increased by feeding flavonoids. Among the Cd groups, liver total lipid concentratons were decreased by feeding flavonoids. Fecal total lipid, fecal cholesterol, and fecal triglyceride excretions were significantly higher in the naringin group, and they were increased by feeding flavonoids among Cd groups. Thiobarbituric acid reactive substance concentrations in plasma and liver were higher in Cd groups, and were significantly decreased by feeding flavonoids. The activities of erythrocyte catalase, superoxide dismutase and glutathione peroxidase showed a tendency to increase by feeding. The activities of liver catalase, superoxide dismutase and glutathione peroxidase were not significantly affected by administering Cd or flavonoids. In conclusion, all flavonoids that were used in this experiment inhibited lipid peroxide formation in plasma and liver, but this effect was not caused by the increased in the activities of antioxidative enzymes.

The present study was conducted to investigate the effect of sea tangle and hypoglycemic agent on lipid metabolism in normal and dabetic rats. Male Sprague-Dawely rats were fed AIN-76 based experimental diets containing 5%(w/w) cellulose or 15%(w/w) sea tangle for 3 weeks, after which diabetic groups were made diabetic by intramuscular injection of streptozotocin(STZ, 45mg/kg BW). Metformin(350mg/kg BW) as a hypoglycemic agent was given once a day using a feeding tube for 5 days. Body weight grains were reduced significantly by STZ treatment, but not influenced by metformin feeding. Blood glucosel levels in sea tangle groups were reduced, compared with those in cellulose groups. Metformin feeding showed the lowering effect of blood glucose. Plasma levels of triglyceride were increased significantly in diabetic rats, but decreased in metformin group by sea tangel feeding. Total cholestero contents showed a similar tendency with triglyceride, but were reduced in diabetic groups without metformin by sea tangle feeding. Plasma levels of HDL-cholesterol were reduced in diabetic rats, compared with those in normal rats. There was a significant increase in fecal weights in diabetic rats fed sea tangle. Fecal contents of cholesterol were lower in diabetic rats than in normal rats. In normal rats, it tended to increase by sea tangle feeding, but not significantly. Fecal excretions of coprostanol and coprostanone were reduced significantly in diabetic rats, compared with those of normal rats. It tended to increase in diabetic rats by simultaneous feeding of sea tangle and metformin, but not significantly. Diabetes reduced fecal excretion of bile acid, but it was increased by sea tangle and metformin feeding.

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.
